Description

Matter No. P39445 -WOSIGNAL STRENGTH INDICATIONS TO PREVENT CONNECTION LOSS BETWEEN PERIPHERAL MEDICAL MONITORING DEVICE AND CENTRAL MEDICAL MONITORING DEVICEBACKGROUND

[0001] People with medical conditions or other health-related conditions often need to monitor events to maintain their health. For example, a person with diabetes often needs to monitor their current glucose level regularly to make sure their glucose level does not go too high or too low. These people may perform continuous monitoring to determine whether applied therapeutic interventions are having the intended effect, or if additional interventions are needed to help treat their condition.

[0002] Individuals with medical conditions may use a sensor to continuously monitor their analyte levels. For example, these individuals may use a continuous glucose monitor to monitor blood-glucose levels. These individuals may rely on communications between the sensor and the user’s mobile device, such as the user cell phone, to provide alarms to notify them when analyte levels are going too high or too low, changing faster than a threshold in one direction or another (or predicted to change faster than a threshold in one direction or another), and / or of other adverse situations with either themselves or in the system (e.g., sensor malfunction, sensor expiration, sensor temperature too high or low, etc.). The alarms may allow the individual to properly monitor their medical condition.

[0003] The user’s mobile device and the sensor may move away from each other and the sensor may lose connection with the user’s mobile device, thereby causing the user’s mobile device to fail to receive sensor data for allowing the user to monitor the medical condition, and which may prevent providing data and / or notifications to the user to properly treat the user’s medical condition.

[0004] Some mobile devices may provide a Connection Loss Warning (CLW) notification to inform the user when the sensor’s connection to the mobile device is lost or below a threshold. However, the CLW notification merely notifies the user of a complete signal loss or loss below a threshold. If the user is too far from their mobile device at the time of the CLW notification, the user may miss the CLW notification.Matter No. P39445 -WOSUMMARY

[0005] Embodiments are described herein for performing one or more actions based on a signal strength of a connection between a central medical monitoring device and a peripheral medical monitoring device. As described herein, a wireless connection may be established between the peripheral medical monitoring device and the central medical monitoring device. The central medical monitoring device may identify that a signal strength of the wireless connection is below an initial signal strength threshold. The central medical monitoring device may determine a corresponding signal strength notification of a plurality of signal strength notifications based on a relative signal strength of the wireless connection below the initial signal strength threshold. The plurality of signal strength notifications may comprise different levels or types of signal strength notifications configured to be provided via different sensory channels. The central medical monitoring device may provide the determined signal strength notification via at least one sensory channel.

[0006] The different sensory channels comprise one or more of an audible sensory channel, a haptic sensory channel, or a visible sensory channel. In one example, the plurality of signal strength notifications may comprise an audible signal strength notification and a visible signal strength notification. The audible signal strength notification may correspond to a first signal strength threshold. The visible signal strength notification may correspond to a second signal strength threshold that is higher than the first signal strength threshold. The audible signal strength notification may be one of a plurality of audible signal strength notifications configured to be provided at different levels. Each level of the plurality of audible signal strength notifications may correspond to a signal strength threshold that is lower than the second signal strength threshold to which the visible signal strength notification corresponds. The different levels of the audible signal strength notifications comprise different frequency levels, different levels of recurrence, different sound pressure levels (SPLs), or different volume levels.

[0007] The central medical monitoring device may identify a change in the signal strength of the wireless connection that may infer a type of interference (e. ., physical or electromagnetic obstruction), and maintain a current notification. For example, the central medica monitoring device may identify a change in the signal strength of the wireless connection at a rate greater than a threshold rate of change and maintain a signal strength notification after the signal strength is below a threshold that corresponds to another signal strength notification.Matter No. P39445 -WOThe central medical monitoring device may detect movement (e.g., via one or more sensors) of the central medical monitoring device and maintain the signal strength notification after the signal strength changes to below a threshold that corresponds to another signal strength notification.

[0008] The central medical monitoring device may operate to change an operation of another device in response to changes in the signal strength of the connection with the peripheral medical monitoring device. For example, the central medical monitoring device may operate as a primary display and provide visible signal strength notifications. The central medical monitoring device may identify a change in the signal strength of the wireless connection to below a primary display transfer threshold and transmit a message configured to transfer the role of primary display from the central medical monitoring device to another device. The central medical monitoring device may identify a change in the signal strength of the wireless connection to below a transmission power boost threshold and transmit a message configured to cause the peripheral medical monitoring device to increase a transmission power for a period of time.

[0009] The peripheral medical monitoring device may comprise a glucose monitoring device. The central medical monitoring device may receive blood glucose level measurements associated with a user from the glucose monitoring device. The signal strength notifications may be disabled from being provided when the blood glucose level of the user is within a predefined range and the signal strength notifications may be provided via the at least one sensory channel from the central medical monitoring device when the blood glucose level of the user is above or below the predefined range.BRIEF DESCRIPTION OF THE DRAWINGS

[0017] FIG. 1 A is a perspective view of a representative user environment. As shown in FIG. 1A, a user 100 may be a person with a medical condition. For example, the user 100 may be a person with a medical condition. The user 100 may use one or more devices to help monitor and / or treat the medical condition. For example, the user 100 may use one or more devices to help monitor an analyte level and / or treat the medical condition. In one example, the medical condition may include a diabetic condition. The diabetic condition may include a metabolic syndrome, pre-diabetes, type 1 diabetes, type 2 diabetes, and / or gestational diabetes. The user 100 may be in an extreme diabetic state, such as hypoglycemia or hyperglycemia, when the blood glucose level of the user 100 is above or below a threshold blood glucose level.

[0018] The one or more devices that may be used to help monitor and / or treat the medical condition of the user 100 may include a central medical monitoring device and / or one or more peripheral medical monitoring devices. For example, a mobile device 104 of the user 100 may operate as a central medical monitoring device, as the mobile device 104 may be configured with applications and / or other software for managing the medical condition of the user 100, communicating with multiple devices for sending / receiving data for managing the medical condition, and / or performing other functionality central to the management of the medical condition of the user 100. In another example, a remote computing device 122 may operate as a central medical monitoring device. Though a single central medical monitoring device may be provided as an example, one or more central medical monitoring devices may be implemented for performing, as described herein. One or more other medical monitoring devices may operateMatter No. P39445 -WOas peripheral devices or peripheral medical monitoring devices capable of connecting to the central medical monitoring device (e.g., mobile device 104) for transmitting data and / or receiving instructions that may allow the user 100 to monitor and / or treat their medical condition. In one example, the one or more peripheral medical monitoring devices may include sensors for measuring one or more analyte levels of the user 100. The central medical monitoring device (e.g., mobile device 104) may receive data from the one or more peripheral medical monitoring devices for being displayed to the user 100 and / or for being communicated to other computing devices (e.g., remote computing device 122). Peripheral devices may also, or alternatively, be referred to as slave devices.

[0019] The peripheral medical monitoring devices may include one or more glucose monitoring devices that may be used to monitor blood glucose levels and / or one or more blood glucose treatment devices that may be used to treat a diabetic condition of the user 100. A glucose monitoring device may include any device that detects and reports a level of glucose in the blood of the user 100, either through direct measurement of the blood or through an indirect detection process. A blood glucose level is also referred to as a blood sugar level. Examples of glucose monitoring devices include, but are not strictly limited to, continuous glucose monitoring devices, flash glucose monitoring devices, and blood glucose meters that provide a single measurement of blood glucose levels from a blood sample in a “spot” monitoring process. A blood glucose treatment device may include any device that treats a diabetic condition of the user 100, either through direct treatment into the blood or through an indirect treatment process or by providing information to allow for treatment.

[0020] In some embodiments, the blood glucose monitoring device and / or blood glucose treatment device is a pen device 103. The pen device 103 may include any injector pen capable of monitoring and / or managing insulin delivery. Example pen devices may communicate with an external device, such as the mobile device 104 and / or a remote computing device 122, to determine insulin levels, calculate doses, track doses, deliver insulin, and / or provide other information such as notifications or alerts. In some examples, pen devices may periodically communicate data indicating the blood glucose levels of the user 100 to an external device, such as a mobile device 104, for computing or storing the blood glucose levels of the user 100.

[0021] In some embodiments, the glucose monitoring device is a continuous glucose monitor (CGM) 102. The CGM 102 includes a subcutaneous sensor that is used to sense andMatter No. P39445 -WOmonitor the amount of glucose in interstitial fluid of the user 100. The CGM 102 includes a transmitting device that is located directly over the sensor that wirelessly powers the data transfer from the sensor. The CGM 102 periodically communicates data indicating the blood glucose levels of the user 100 to an external device, such as a mobile device 104, for computing or storing the blood glucose levels of the user 100.

[0022] Some embodiments of the mobile device 104 operate as a CGM controller device. Though the mobile device 104 is provided as an example of a device with which the CGM 102 communicates, the CGM 102 may communicate with other dedicated CGM controller devices for providing similar functionality that is described herein for the mobile device 104. In some cases, the CGM 102 processes the blood glucose data to provide an amount of glucose in interstitial fluid of the user 100. In some cases, the CGM 102 provides the blood glucose data to the mobile device 104 and / or pen device 103, and the mobile device 104 and / or pen device 103 processes the blood glucose data to manage the diabetic condition and provide treatment notifications as described herein.

[0023] In some embodiments, the blood glucose monitoring device is a flash glucose monitor (FGM) 111. The FGM 111 includes a subcutaneous sensor that is used to sense and monitor the amount of glucose in interstitial fluid of the user 100. A separate reader device, such as the mobile device 104, pen device 103, or another reader device, receives the blood glucose data from the sensor of the FGM 111 when the device is within range, such as but not limited to the RF range, of the sensor. The FGM 111 transmits an instantaneous blood glucose level or a graphical trend of the blood glucose level to the reader device for display. The mobile device 104 processes the blood glucose data to manage the diabetic condition and provide treatment notifications as described herein.

[0024] In some embodiments, the user 100 uses a blood glucose meter (BGM) 106 as a blood glucose monitoring device to monitor blood glucose levels. The BGM 106 includes a port 108 that receives a blood glucose measurement strip 110. The user 100 deposits a sample of blood on the blood glucose measurement strip 110. The BGM 106 analyzes the sample and measures the blood glucose level in the sample. The blood glucose level measured from the sample is displayed on a display 112 of the BGM 106 or communicated to an external device, such as the mobile device 104. The mobile device 104 processes the blood glucose data to manage the diabetic condition and provide treatment notifications as described herein.Matter No. P39445 -WO

[0025] The blood glucose level measured by the pen device 103 or BGM 106 or computed using data received from the CGM 102 or FGM 111, is used to treat the diabetic condition of the user 100. For example, the user 100 may use an insulin pump 116 (e.g., ambulatory non-durable insulin pump or an ambulatory durable insulin pump) to treat the diabetic condition with insulin. The mobile device 104 may determine an amount of insulin to be administered to the user 100 and the insulin pump 116 may receive instructions from the mobile device 104 to deliver a predetermined amount of insulin to the user 100. The insulin pump 116 may receive other information from the mobile device 104, such as mealtime information or exercise information of the user 100. The insulin pump 116 may determine the amount of insulin to administer based on the received information from the mobile device 104. The insulin pump 116 may communicate information to the mobile device 104. The information communicated to the mobile device 104 may include an amount of insulin delivered to the user 100, corresponding times of delivery, and / or a pump status (e.g., battery status, insulin status, pump malfunctions, and / or another status of a portion of the pump). A pump malfunction may include an occlusion, a mechanical malfunction, an electronic malfunction, and / or another malfunction detected by the pump 116 (e.g., via one or more sensors thereon).

[0026] The mobile device 104 communicates with the CGM 102, FGM 111, the BGM 106, the insulin pump 116, and / or pen device 103 using wired or wireless communications that are transmitted and received between devices on a wired or wireless communication medium. The mobile device 104 may also, or alternatively, receive data from a monitoring device (e.g., the CGM 102, FGM 111, the BGM 106, the insulin pump 116, and / or pen device 103) indirectly via one or more other devices (e.g., a remote computing device 122 or another computing device). For example, a monitoring device may be capable of communicating data to one or more intermediate computing devices for storing data thereon for being transmitted to and / or requested by the mobile device 104. The mobile device 104, the CGM 102, a CGM controller, the BGM 106, the FGM 111, the insulin pump 116, and / or pen device 103 may be collectively referred to as user devices or computing devices. The mobile device 104 communicates with the CGM 102, the FGM 111, the BGM 106, the insulin pump 116, and / or pen device 103 using the same or different wired or wireless protocols. For example, the mobile device 104 may communicate with the CGM 102, FGM 111, the BGM 106, the insulin pump 116, and / or pen device 103 using BLUETOOTH®, near field communication (NFC), THREAD®, WIFI®,Matter No. P39445 -WOZIGBEE®, WI-MAX®, a cellular communication protocol, a proprietary wireless communication protocol, or another radio frequency (RF) communication protocol. Though various blood glucose monitoring devices (e. ., pen device 103, CGM 102, BGM 106, FGM 111, and / or another blood glucose monitoring device) are provided as examples of peripheral medical monitoring devices that may operate as analyte monitoring devices, other analyte monitoring devices may be implemented for measuring and / or monitoring other analyte levels of the user 100.

[0027] The mobile device 104 may establish a connection to one or more peripheral medical monitoring devices (e.g., pen device 103, CGM 102, BGM 106, FGM 111, a blood potassium monitoring device, and / or another analyte monitoring device) at a time. For example, the mobile device 104 may establish a connection via a wired or wireless communication medium with one or more blood glucose monitoring devices. The connection may be established via a wired or a wireless communication protocol, such as BLUETOOTH®, NFC, THREAD®, WIFI®, ZIGBEE®, WI-MAX®, or another RF communication protocol. The mobile device 104 may transmit and / or receive data via the one or more established connections for assisting in monitoring and / or treating the diabetic condition. The connection between devices may be initiated by the transmission and / or receipt of a connection request message from one of the devices via a communication medium. Another device may transmit a connection response message in response to the connection request message via the communication medium. The devices may detect that the connection has been established based on the exchange of the connection request / connection response messages and / or subsequent messages, such as acknowledgement messages, messages for establishing secure communications, or other subsequent messages e.g., depending on the communication protocol).

[0028] The mobile device 104 may receive data from other devices and / or input from the user 100 via a user interface for being provided on a display. The mobile device 104 may receive input via hard buttons or soft buttons provided on the display. In response to the data that is received at the mobile device 104, the mobile device 104 may provide output to the user 100 in the form of visual output on the display, audio output via a speaker, haptic feedback via vibrations, and / or other output to the user 100.Matter No. P39445 -WO

[0029] The mobile device 104 may be a connected smart device and / or may be in communication with other connected smart devices. Example connected smart devices may include a wearable device. Though the mobile device 104 is provided as an example of a connected smart device and / or a central medical monitoring device, other mobile devices may be implemented by the user 100 as connected smart devices and / or a central medical monitoring device. For example, the user 100 may implement mobile device 104a, which may be a wearable device comprising a display. The connected smart devices may include an armband (e.g., a smart watch, such as an APPLE® watch, a FITBIT® armband, or other device capable of being worn on the arm of the user 100), a ring, glasses (e.g., GOOGLE® GLASS™), a headset (e. ., BLUETOOTH® headset), clothing (e.g., shirts, gloves, etc.), or another wearable device capable of being worn by the user 100. The connected smart devices may be a wearable device or other device capable of monitoring the heart rate of the user 100, such as a heart rate monitor. The connected smart devices may include a device capable of monitoring a wake / sleep state of the user 100, such as a wearable device, a heart rate monitor, a smart bed, or another device.

[0030] The mobile devices 104, 104a may be capable of communicating with one another and / or one or more peripheral medical monitoring devices via the wires and / or wireless communications described herein. The mobile devices 104, 104a may communicate with each other and the peripheral medical monitoring devices via the same or different communication protocols. The peripheral medical monitoring devices may be capable of connecting with each of the mobile devices 104, 104a individually and / or simultaneously.

[0031] The mobile devices 104, 104a may each be configured to determine information corresponding to the device’s location (i.e., location information). For example, each mobile device 104, 104a may be able to determine the geolocation (e.g., latitude and longitude) of the mobile device 104 using signals from a global positioning system (GPS) or triangulation via cellular communications. The mobile devices 104, 104a may each communicate with the remote computing device 122 for accessing a third-party service (e.g., via an application programming interface (API)), for example, to determine the location of the mobile device 104 or access other software / applications. In one example, the mobile devices 104, 104a may each provide data received from one or more devices to the remote computing device 122, via the network 120, for performing one or more processes described herein. The mobile device 104, 104a may eachMatter No. P39445 -WOreceive a response from the remote computing device 122 with information for being displayed to the user 100 and / or for being communicated to other devices.

[0032] Some embodiments of the mobile devices 104, 104a include one or more sensors for detecting a relative position of the device or information about the user 100. The mobile devices 104, 104a may each detect a movement or a change in orientation. Based on the movement or change in orientation (or lack thereof) of a mobile device 104, 104a over a period of time, the mobile device 104, 104a may detect that the user 100 is standing, sitting, or lying down. In other words, the mobile device 104, 104a may detect / infer that the user 100 is awake. The mobile device 104, 104a may detect that the user 100 is exercising when the movement or a change in orientation is greater than a threshold for a period of time. The mobile device 104, 104a may detect the heartrate of the user 100 using a heartrate sensor. Based on the heartrate and / or the movement of the user 100 over a period of time, the mobile device 104, 104a may detect whether the user 100 is asleep or awake. The information about the mobile device 104 or the user 100 is used to provide information about or treat the diabetic condition.

[0033] The mobile devices 104, 104a may each provide information to the user 100 about the user’s medical condition. For example, the mobile devices 104, 104a may each provide analyte levels (e.g, blood glucose levels), meal-related information, exercise-related information, treatment notifications, and / or graphs and other graphical user interfaces, such as alerts or notifications, for display. The mobile devices 104, 104a may each provide therapeutic protocol data to the pen device 103. For example, the mobile devices 104, 104a may each provide insulin dose levels for an associated medication titration event (e.g., basal insulin titration event) to the pen device 103. Having received the insulin dose level, the pen device 103 may be configured to administer a corresponding amount of insulin.

[0034] The mobile devices 104, 104a may each communicate with other devices directly via a wired communication and / or a short-range wireless communication (e.g, WI-FI®, BLUETOOTH®, BLE, NFC, or another suitable short-range wireless communication). The mobile device 104 may communicate indirectly with remote computing device(s) 122 via a network 120 (c.g, using a WI-FI® network, a cellular network, a WLMAX® network, or another wired or wireless network). The network 120 is a wired or wireless network. The network 120 is used to communicate over the Internet to other devices.Matter No. P39445 -WO

[0035] The mobile devices 104, 104a may each communicate with the remote computing device(s) 122 to generate user interfaces for display on the mobile device 104, 104a, perform remote computation, or to otherwise control a remote computing device. For example, the mobile device 104 may provide a user interface via an application (e.g., a web browser or other local application) that is generated locally for providing access to locally stored data or data from a remote computing device 122.

[0036] As described herein, the mobile devices 104, 104a may each display information to the user 100 to assist in treatment of the user’s medical condition. For example, as described herein, the mobile devices 104, 104a may each provide information to the user 100 related to the user’s health, devices assisting in treatment of the medical condition (e.g., a bolus or insulin level for treating a diabetic condition, an amount of potassium for treating a blood potassium condition, or another form of treatment), a current state of the user’s medical condition (e.g., including measured and / or monitored analyte levels, such as blood glucose levels and / or other analyte levels), and / or other information related to the user 100, the user’s medical condition, and / or one or more devices to enable proper treatment of the user’s medical condition. The mobile devices 104, 104a may each provide notifications to the user 100. The mobile devices 104, 104a may each provide notifications via one or more notification types. For example, the notifications may be provided via a visual notification on a graphical user interface displayed on the mobile devices 104, 104a, a visual notification provided via a display or one or more light emitting diodes (LEDs), an audible notification provided via a speaker or other audio device on the mobile device 104, 104a, a tactile or vibratory notification on the mobile device 104, 104a, and / or another notification type provided via the respective mobile devices 104, 104a or another device in the user environment. The notifications may be provided to the user 100 via an application (e.g., a medical application, such as a diabetes-related application, an exercise-related application, a nutrition or mealtime-related application, another health-related application, or another type of application) residing locally thereon and / or via one or more remote computing devices 122. For example, one or more remote computing devices 122 may be implemented to execute the application for providing a graphical user interface with the notifications for providing the information related to the medical condition of the user 100 and / or treatment thereof.Matter No. P39445 -WO

[0037] The mobile devices 104, 104a may each provide a notification (e.g, or alert) to the user 100 in response to different triggering events. For example, the mobile devices 104, 104a may each provide a notification to the user 100 if the user’s analyte level is greater than or less than a threshold. The CGM 102 may provide regular or continuous data indicating the glucose levels of the user 100, while the CGM 102 is connected to the mobile devices 104, 104a, and the mobile devices 104, 104a may each notify the user 100 when the analyte levels are outside of a normal or healthy range (e.g., at or above a predefined high-end threshold and / or below a predefined low-end threshold). The mobile devices 104, 104a may each also receive data related to the medical condition of the user 100 from the remote computing device 122 and notify the user 100 in response to such data.

[0038] As the mobile devices 104 may operate as a primary display or primary central medical monitoring device and may become unable to properly receive and / or monitor data from other devices (e.g., analyte monitoring devices, remote computing device 122, and / or another device) if it becomes disconnected from those devices, the mobile device 104 may provide notifications to the user 100 when the mobile device 104 becomes disconnected from another device (e.g., one or more peripheral medical monitoring devices), such that the user 100 may understand that their analyte levels or other information related to their medical condition may be changing. The mobile device 104 may also, or alternatively, transfer the role of primary display or primary central medical monitoring device to the mobile device 104. As shown in FIG. IB, the mobile device 104 may become disconnected from one or more peripheral medical monitoring devices, which may include analyte measurement devices such as the pen device 103, CGM 102, BGM 106, FGM 111, and / or another analyte monitoring device. The disconnections between the mobile device 104 and the peripheral medical monitoring devices may be the result of the peripheral medical monitoring device losing power, a range or distance between the mobile device 104 and the peripheral medical monitoring device, a congested RF environment, and / or other RF interference (e.g., walls or other physical structures). A congested RF environment may include multiple devices communicating on a same RF band, a physical interference, and / or an electromechanical interference. For example, if the mobile device 104 and the peripheral medical monitoring device are communicating on a BLUETOOTH communication link, the greater the number of other devices communicating within the same space on the same communication link may cause a greater amount of interference with theMatter No. P39445 -WOcommunications between the peripheral medical monitoring device and the mobile device 104. A relatively strong source of interference on an overlapping RF band can also cause interference with the communications between the mobile device 104 and the peripheral medical monitoring. For example, if the mobile device 104 and the peripheral medical monitoring are communicating on a BLUETOOTH communication link, a WIFI hotspot (e.g., a router device) may cause a relatively large amount of interference with the communications between the peripheral medical monitoring and the mobile device 104 due to the overlapping portions of the communication band (e. ., overlapping portions of the 2.4 GHz ISM band) on which the protocols may communicate. When the interference level of communications between the peripheral medical monitoring device and the mobile device 104 is above a certain threshold, the peripheral medical monitoring device and the mobile device 104 may be unable to successfully communicate, resulting in the disconnection. Similar causes of interference may result in the mobile device 104 becoming disconnected from other devices, such as the remote computing device 122, other peripheral medical monitoring devices in the system, and / or other third-party devices communicating with the mobile device 104 on the same protocol or communication link.

[0039] In response to devices, such as one or more of the peripheral medical monitoring devices and the mobile device 104, becoming disconnected or reaching a signal strength that is below a threshold, the mobile device 104 may provide a notification (e.g., or alert) to the user 100. For example, the mobile device 104 may execute an application (e.g., a health-related application or another application related to the medical condition of the user 100, such as a diabetes-related application) thereon that is configured to detect that the mobile device 104 and the peripheral medical monitoring device are disconnected and provide the notification to the user 100. The disconnection or signal strength falling below a threshold may be detected by the application executing on the mobile device 104 based on a failure to receive one or more messages (e.g., in response to a request or an anticipated message) within a period of time. The mobile device 104 may identify that its connection with the peripheral medical monitoring is below a signal strength threshold and alert the user 100 that data related to the user’s medical condition may be at risk of failing to be properly monitored at the mobile device 104. The mobile device 104 may provide such notifications to the user 100 via the one or more notification types (e.g., a visual notification, an audible notification, a tactile or vibratory notification, and / or another notification type).Matter No. P39445 -WO

[0040] As the interference level between the mobile device 104 and the peripheral medical monitoring on the RF communication link and / or the range or distance between the devices changes, the mobile device 104 may continue to disconnect and reconnect to the peripheral medical monitoring device causing multiple notifications to be provided to the user 100 within the period of disconnections and reconnections.

[0041] The mobile device 104 may provide one or more notifications to a user to indicate a relative signal strength of the connection on the RF communication link between the mobile device 104 and one or more peripheral medical monitoring devices to inform the user 100 when the connection is at or between one or more thresholds. For example, the mobile device 104 may be configured with one or more signal strength threshold before completely losing connection to the peripheral medical monitoring device or the connection is below a low-end threshold, and may provide notifications to the user 100 as feedback prior to the loss of connection or the low-end threshold. The feedback may be provided via one or more sensory channels, such as audible, visible, and / or haptic sensory channels, to indicate when the signal strength of the connection between the mobile device 104 and the peripheral medical monitoring device are at different thresholds. The feedback may allow the user 100 to be more likely to be notified and / or aware that the user 100 may need to perform remedial action (e.g., moving the devices closer to each other, removing forms of interference, moving to a location with less interference, turn on setting for communication on one of the devices, increasing transmit power at one or more of the devices, etc.) to improve the connection between the mobile device 104 and the peripheral medical monitoring device to prevent the loss of data (e.g., analyte values, warnings, alerts, error messages, reminders, etc.) in monitoring and / or treating the medical condition of the user 100.

[0042] The signal strength may include and / or be determined from a received signal strength indicator (RSSI) value. The RSSI value may be a measurement of the power level received by an antenna from a radio frequency (RF) signal. In the context of BLUETOOTH and / or other RF enabled devices, RSSI may be used to estimate the signal strength of the RF communication link or connection between the RF enabled devices. The RSSI value may include a measurement of the power level of the received signal. The RSSI may represent the strength of the radio signal between the transmitter of the transmitting device and the receiver of the receiving device. A stronger RSSI value may indicate a stronger signal, which may be the result of and / or indicate devices that are a closer distance to each other. Conversely, a weakerMatter No. P39445 -WORSSI value may indicate a weaker signal, which may be the result of and / or indicate devices that are a further distance from each other or have an obstruction between the devices. Though RSSI values are provided as an example measure of signal strength between two devices, other metrics may be implemented to measure signal strength of a communication link between devices.

[0043] FIG. 2 is a flow diagram illustrating an example process 200 for providing notifications to a user based on a relative signal strength between the central medical monitoring device and the peripheral medical monitoring device. One or more portions of the process 200 may be performed by one or more computing devices. For example, the one or more portions of the process 200 may be performed by central medical monitoring devices, such as mobile device 104 shown in FIGs. 1A and IB. One or more portions of the process 200 may be stored in memory as computer-readable or machine-readable instructions that may be executed by a processor of the one or more computing devices. Though portions of the process 200 may be described herein as being performed by a particular computing device, the process 200 may be performed by another computing device or distributed across multiple computing devices, such as one or more central medical monitoring devices (e.g., mobile devices, remote computing devices, or other central medical monitoring devices), peripheral medical monitoring devices (e.g, analyte monitoring devices), and / or one or more other devices. Though the process 200 may illustrate a sequence of steps or events in a particular order, the sequence of steps or events may be performed in another order.

[0044] As shown in FIG. 2, at 202, a wireless connection may be established on a wireless communication link between a central medical monitoring device ( .g, a mobile device) and a peripheral medical monitoring device (e.g, an analyte monitoring device, such as a continuous glucose monitoring device). For example, the central medical monitoring device may initiate device communication by establishing a BLUETOOTH or BLUETOOTH Low Energy (BLE) connection between the central medical monitoring device and the peripheral medical monitoring device. The central medical monitoring device may establish this connection by scanning for peripheral medical monitoring devices, identifying the peripheral medical monitoring devices through unique identifiers, and initiating secure pairing protocols with at least one peripheral medical monitoring device. Once identified, the central medical monitoring device may initiate secure pairing protocols with the peripheral medical monitoring device, which may include exchanging public keys for encrypted data transmission to ensure security and data integrity. TheMatter No. P39445 -WOcentral medical monitoring device may negotiate connection parameters (e.g., data rates, intervals, and / or transmission power) to optimize power consumption and data reliability. After successful pairing, the central medical monitoring device may maintain the status of the connection, keeping the communication channel open and ready for data exchange, which can include, for example, periodically sending keep-alive signals to maintain the connection and confirm connection stability and / or quality above a threshold.

[0045] At 204, the central medical monitoring device may monitor the signal strength of the connection between itself and the peripheral medical monitoring device. The signal strength may include an RS SI value, for example. This monitoring may involve regular checks for data packet exchanges and / or assessing connection integrity, such as verifying the presence of expected acknowledgment signals for transmitted packets.

[0046] At 206, the central medical monitoring device may determine whether the signal strength of the connection to the peripheral medical monitoring device is below an initial threshold. If the signal strength of the connection with the peripheral medical monitoring device is not below the initial threshold at 206, the central medical monitoring device may continue monitoring the connection status at 204. The connection on the wireless communication link may remain stable, and the central medical monitoring device may exchange data with the peripheral medical monitoring device (e.g., receiving analyte values and / or notifications).

[0047] If the signal strength of the connection with the peripheral medical monitoring device is below the initial threshold at 206, the central medical monitoring device may determine a relative signal strength below the threshold at 208. The central medical monitoring device may have different thresholds between the initial threshold and a threshold at which a loss of the connection is established for providing different types of notifications. The relative signal strength may trigger different types of notifications based on the signal strength being below the different thresholds. The different types of notifications may be provided via the same or different sensory channels. For example, the sensory channels may include audible sensory channels e.g., providing audible notifications), visible sensory channels (e.g. providing visible notifications), and / or haptic sensory channels (e.g., providing haptic notifications).

[0048] At 210, the central medical monitoring device may provide a notification based on the relative signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device based on the relative signal strength below theMatter No. P39445 -WOinitial threshold and the threshold at which a loss of the connection is determined. The different thresholds may trigger notifications at different sensory levels (e.g., volume, brightness, size, intensity of vibrations, or other sensory level) provided via the same sensory channel (e.g., audible, visible, or haptic notifications) and / or notifications provided via different sensory channels.

[0049] In one example, the central medical monitoring device may provide an audible notification that is progressively louder as the relative signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device is progressively weaker. The central medical monitoring device may also provide a progressively quieter audile notification as the relative signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device is progressively stronger. The progressive increase / decrease in the volume of the audible notification may operate as an active pre- warning distance notification to alert the user that they are getting closer to or further away from a loss of connection between the central medical monitoring device and the peripheral medical monitoring device.

[0050] FIG. 3A is a flow diagram illustrating an example process 300 for providing progressive signal strength notifications to a user based on a relative signal strength between the central medical monitoring device and the peripheral medical monitoring device. One or more portions of the process 300 may be performed by one or more computing devices. For example, the one or more portions of the process 300 may be performed by central medical monitoring devices, such as mobile device 104 shown in FIGs. 1A and IB. One or more portions of the process 300 may be performed by a peripheral medical monitoring device, such as a glucose monitoring device or another analyte monitoring device. One or more portions of the process 300 may be stored in memory as computer-readable or machine-readable instructions that may be executed by a processor of the one or more computing devices. Though portions of the process 300 may be described herein as being performed by a particular computing device, such as a central medical monitoring device, the process 300 or portions thereof may be performed by another computing device or distributed across multiple computing devices, such as one or more central medical monitoring devices e.g., mobile devices, remote computing devices, or other central medical monitoring devices), peripheral medical monitoring devices (e.g., analyte monitoring devices), and / or one or more other devices. Though the process 300 may illustrate aMatter No. P39445 -WOsequence of steps or events in a particular order, the sequence of steps or events may be performed in another order.

[0051] As shown in FIG. 3A, at 302, a wireless connection may be established on a wireless communication link between a central medical monitoring device and a peripheral medical monitoring device. For example, the central medical monitoring device may initiate device communication by establishing a BLUETOOTH or BLUETOOTH Low Energy (BLE) connection between the central medical monitoring device and the peripheral medical monitoring device.

[0052] At 304, the central medical monitoring device may monitor the signal strength of the connection between itself and the peripheral medical monitoring device. The signal strength may include an RSSI value, for example. This monitoring may involve regular checks for data packet exchanges and / or assessing connection integrity, such as verifying the presence of expected acknowledgment signals for transmitted packets.

[0053] At 306, the central medical monitoring device may determine whether the signal strength of the connection to the peripheral medical monitoring device is below an initial threshold. If the signal strength of the connection with the peripheral medical monitoring device is not below the initial threshold at 306, the central medical monitoring device may continue monitoring the connection status at 304. The connection on the wireless communication link may remain stable, and the central medical monitoring device may exchange data with the peripheral medical monitoring device (e.g, receiving analyte values and / or notifications).

[0054] If the signal strength of the connection with the peripheral medical monitoring device is below the initial signal strength threshold at 306, the central medical monitoring device may provide a signal strength notification at 308. For example, the signal strength notification may include a signal strength notification on one or more sensory channels, such as an audible signal strength notification configured to provide notifications via an auditory sensory channel, a visible signal strength notification configured to provide notifications via a visual sensory channel, and / or a haptic signal strength notification configured to provide notifications via a tactile sensory channel.

[0055] The audible signal strength notification may be provided at a defined level, such as a frequency level (e.g., pitch), a level of recurrence, a sound pressure level (SPL) (e.g, “loudness”) and / or a volume level. The audible signal strength notification may be increased inMatter No. P39445 -WOfrequency level, a level of recurrence, SPL, and / or volume level as the signal strength increases to corresponding signal strength thresholds. The audible signal strength notification may be decreased in frequency level, a level of recurrence, SPL, and / or volume level as the signal strength decreases to corresponding signal strength thresholds. The SPL may increase with distance to compensate for the user moving away from the central medical monitoring device with the peripheral medical monitoring device. As the distance from a sound source decreases, the SPL may decrease by 6 a-weighted decibels (dBA).

[0056] The visible signal strength notification may include an overlay notification provided in an application (e.g., a medical application, such as a diabetes-related application, an exercise-related application, a nutrition or mealtime-related application, another health-related application, or another type of application) or an operating system (OS)-layer notification (e.g., lock screen, call screen, home screen, or other graphical user interface provided by the operating system). The OS-level notifications may be displayed when the application is operating in the background and / or terminated. The visible signal strength notification may include information or feedback related to the signal strength of the connection between the medical monitoring device and the peripheral medical monitoring device. For example, the visible signal strength notification may identify a level (e.g., “one”, “two”, etc.) of the threshold and / or signal strength notification, a level or percentage of the signal strength (e.g., “eighty percent signal strength”), a notification of distance (e.g., “distance too far”), instructions to decrease the distance or perform other remedial action, and / or a notification of potential connection loss or action to prevent connection loss (e.g., “connection loss soon”). The level of the visible signal strength notification may indicate a primary display on which the visible signal strength notification is provided. For example, different levels of the visible signal strength notification may be configured to be displayed on the mobile device of the user, a wearable device (e.g., a smart watch or other wearable device), and / or another device selected as a primary display on which the visible signal strength notification is provided. The mobile device may send a message to another device, such as the wearable device or another device selected as a primary display, to cause the other device to display one or more visible signal strength notifications. The message may be sent on the wireless communication link being monitored or another communication link. As the signal strength on the communication ink with the peripheral medical monitoring device may be decreasing, the central medical monitoring device may send the message for providingMatter No. P39445 -WOthe signal strength notification to the peripheral medical monitoring device via another communication link (e.g., another RF communication signal, such as WIFI, cellular, etc.).

[0057] The haptic signal strength notification may be provided via a haptic actuator or vibration motor at the mobile device. In another example, the mobile device may send a message to another device, such as a wearable device, the peripheral medical monitoring device, or another device having a haptic actuator or vibration motor for providing the haptic signal strength notification. The haptic signal strength notification may be increased in intensity level and / or level of recurrence as the signal strength increases to corresponding signal strength thresholds. The haptic signal strength notification may be decreased in intensity level and / or level of recurrence as the signal strength decreases to corresponding signal strength thresholds. The haptic signal strength notification may be implemented to notify the user at further distances between the central medical monitoring device and the peripheral medical monitoring device, such as when the visual and auditory channels may fail to get the user’s attention. The drawback is that it adds hardware components to the sensor increasing cost / bulk / power consumption. In a further iteration, the smartwatch could also take over the alarming responsibilities when the RSSI signal is weakened to indicate to the user (assuming they are distant from their phone) to notify and close the distance or else a connection loss may be imminent. The smartwatch is fully capable of haptic, visual, and / or audible notification modalities as well.

[0058] The signal strength notification at 308 may be at an initial or lowest level for providing the signal strength notification. In another example, the level may correspond to another threshold below the initial signal strength threshold, such as when there is a drop in signal strength within a relatively short period of time. The central medical monitoring device may be configured with different signal strength thresholds between the initial threshold and a threshold at which a loss of the connection is established for providing corresponding levels of signal strength notifications.

[0059] At 310, the central medical monitoring device may determine whether the signal strength has decreased below a lower-quality signal strength threshold. For example, the central medical monitoring device may determine that the signal strength of the connection with the peripheral medical monitoring device has decreased below a next lower signal strength threshold. If the signal strength of the connection with the peripheral medical monitoring device has decreased below a lower-quality signal strength threshold at 310, the level of the signalMatter No. P39445 -WOstrength notification may be adjusted at 318 to increase the level of the signal strength notification provided by the central medical monitoring device. Prior to adjusting the level of the signal strength notification at 318, the central medical monitoring device may determine, at 316, whether the level of the signal strength notification is already at a highest predefined level. If so, the central medical monitoring device may maintain the current level of signal strength notification.

[0060] An increase in the level of the signal strength notifications may increase the perceived urgency related to a potential disconnection between the central medical monitoring device and the peripheral medical monitoring device. The level of the signal strength notification may be increased by increasing an audible signal strength notification in frequency level, a level of recurrence, SPL, and / or volume level to the next signal strength threshold. The level of the signal strength notification may be increased by increasing a haptic signal strength notification in intensity level and / or level of recurrence as the signal strength increases to the next signal strength threshold. The level of the signal strength notification mya be increased by updating the information or feedback related to the signal strength of the connection between the medical monitoring device and the peripheral medical monitoring device. For example, the visible signal strength notification may up updated to identify another level (e.g, “one”, “two”, c / c.) of the threshold and / or signal strength notification, another level or percentage of the signal strength ( .g, “eighty percent signal strength”), another notification of distance (c.g, “distance too far”), instructions to decrease the distance or perform other remedial action, and / or another notification of potential connection loss or action to prevent connection loss (e.g., “connection loss soon”). The level of the visible signal strength notification may be updated by changing the primary display on which the visible signal strength notification is provided. For example, the central medical monitoring device may initially display the visible signal strength notification and then send a message to a wearable device (e.g, a smart watch or other wearable device) and / or another device selected as the primary display for displaying an increased level of the visible signal strength notification.

[0061] As the signal strength of the connection with the peripheral medical monitoring device decreases, the decrease in signal strength may indicate that the distance between the central medical monitoring device and the peripheral medical monitoring device has increased and / or an obstruction is between the devices, such that an increase in the level of the notificationMatter No. P39445 -WOmay assist the user in becoming aware of the notification. The user being aware of the notification may allow the user to perform a remedial action or prevent the signal strength from worsening. The remedial action may also prevent the central medical monitoring device from automatically performing remedial action that may use additional resources (e.g., power resources and / or network resources) by increasing transmit power and / or transmitting additional messages due to lost packets.

[0062] The central medical monitoring device may continue to monitor the signal strength of the connection to identify whether the signal strength increases or decreases below defined thresholds for further adjusting the level of the signal strength notification. For example, the central medical monitoring device may determine, at 312, that the signal strength has increased above a higher-quality signal strength threshold. For example, the central medical monitoring device may determine that the signal strength of the connection with the peripheral medical monitoring device has increased above a next higher signal strength threshold. If the signal strength of the connection with the peripheral medical monitoring device has increased above a higher-quality signal strength threshold at 312, the level of the signal strength notification may be adjusted at 318 to decrease the level of the signal strength notification provided by the central medical monitoring device. Prior to adjusting the level of the signal strength notification at 318, the central medical monitoring device may determine, at 314, whether the level of the signal strength notification is still above the initial threshold for providing signal strength notifications. If not, the central medical monitoring device may stop providing the signal strength notifications and continue monitoring the signal strength of the connection with the central medical monitoring device at 304.

[0063] The level of the signal strength notification may be decreased by decreasing an audible signal strength notification in frequency level, a level of recurrence, SPL, and / or volume level to the next signal strength threshold. The level of the signal strength notification may be decreased by decreasing a haptic signal strength notification in intensity level and / or level of recurrence as the signal strength decreases to the next signal strength threshold. The level of the signal strength notification mya be decreased by updating the information or feedback related to the signal strength of the connection between the medical monitoring device and the peripheral medical monitoring device. For example, the visible signal strength notification may up updated to identify another level (e.g., “one”, “two”, etc.) of the threshold and / or signal strengthMatter No. P39445 -WOnotification, another level or percentage of the signal strength (e.g., “eighty percent signal strength”), another notification of distance (e.g., “distance too far”), instructions to decrease the distance or perform other remedial action, and / or another notification of potential connection loss or action to prevent connection loss (e.g., “connection loss soon”). The level of the visible signal strength notification may be updated by changing the primary display on which the visible signal strength notification is provided. For example, the central medical monitoring device may send a message to cause the visible signal strength notification to stop displaying on another device (e.g., a wearable device, such as a smart watch or other wearable device) previously selected as the primary display for displaying a decreased level of the visible signal strength notification. The central medical monitoring device may send a message causing another device to display the visible signal strength notification or may display the visible signal strength notification locally.

[0064] As the signal strength of the connection with the peripheral medical monitoring device increases, the increase in signal strength may indicate that the distance between the central medical monitoring device and the peripheral medical monitoring device has decreased and / or an obstruction between the has been removed, such that a decrease in level may be performed to preserve resources (e.g., battery power) while still assisting the user in becoming aware of the notification.

[0065] If the central medical monitoring fails to detect a decrease in signal strength below a lower-quality signal strength threshold at 310 or an increase in signal strength above a higher-quality signal strength threshold at 312, the central medical monitoring device may continue to provide the same signal strength notification at 308. The signal strength notification may be maintained at 308 for a predefined period of time, until user input is received, and / or the signal strength of the connection with the peripheral medical monitoring device changes. The signal strength notification may also be maintained at the highest level for a predefined period of time, until user input is received, and / or the signal strength of the connection with the peripheral medical monitoring device changes. The signal strength notification may be turned off after a predefined period of time to prevent utilizing battery power and / or additional resources, such as when a user should have been notified if in the area.

[0066] The central medical monitoring device may progressively increase the level of the signal strength notifications as the signal strength of the connection with the peripheral medicalMatter No. P39445 -WOmonitoring device decreases below defined thresholds to notify the user to reduce the distance between the devices, remove an obstruction or interference between the devices, and / or perform other remedial action. The signal strength notifications may be implemented in a manner to avoid unnecessary / frequent notifications and / or causing notification fatigue to the user. For example, each progressive series of notifications may be delayed by a predefined period of time (e.g., 1 minute, 5 minutes, 10 minutes, etc.) or number of measurement cycles (e.g., 1, 2, 5, or more measurement cycles) for measuring the signal strength prior to being triggered. In another example, a predefined period of time (e.g., 1 minute, 5 minutes, 10 minutes, etc.) or number of measurement cycles (e.g., 1, 2, 5, or more measurement cycles) may be implemented between each level of notification based on a change in signal strength threshold, such that a delay period may be implemented for any changes to the signal strength (e.g., RSSI) that cross a corresponding threshold. In another example, the central medical monitoring device may implement a form of hysteresis at each threshold, such that the signal strength of the connection with the peripheral medical monitoring device may go above or below a threshold by a defined amount or for a defined period of time before providing a corresponding signal strength notification. This may avoid causing frequent changes in levels or notifications when the signal strength is changing within the predefined period of time.

[0067] When providing audible signal strength notifications, the central medical monitoring device may enable a microphone to sample an ambient noise level and to proportionally increase the SPL or volume of the audible signal strength notification to compensate for background noise to increase the likelihood that the audible signal strength notification is heard. The microphone may be enabled in the settings of the central medical monitoring device in response to user input. The audible signal strength notifications may include distinctive sounds that represent a condition of signal strength (e.g., a buzz, a beep, a tone, a ring, music, etc.) and / or may include text-to-speech notifications providing a message to the user. For example, the audible signal strength notification may identify a level (e.g., “four”, “five”, etc.) of the threshold and / or signal strength notification, a level or percentage of the signal strength (e.g., “eighty percent signal strength”), a notification of distance (e.g., “distance too far”), instructions to decrease the distance or perform other remedial action, and / or a notification of potential connection loss or action to prevent connection loss (e.g., “connection loss soon”). The audible signal strength notifications may be configured as an auditory icon, such that theMatter No. P39445 -WOauditory icon sounds like a predefined or stereotypical signal (e.g, a “ping”, like on submarine radar or other signal). An auditory icon may include a sound that suggests the meaning of the notification.

[0068] The audible signal strength notifications may include an operating system (OS) level notification. For example, the user may access OS alarm settings on the central medical monitoring device to set specific tones and define the tones for the audible signal strength notifications or for each audible signal strength notification to identify the audible signal strength notifications distinctly from other notifications on the central medical monitoring device and / or to identify different levels of audible signal strength notifications from each other (e.g., higher priority notifications that may correspond with lower levels of signal strength thresholds, or the lowest level threshold). This may prevent the user from confusing the audible signal strength notifications with notifications that are not medically consequential, or allow the user to identify medically consequential notifications and / or higher-priority medically consequential notifications more easily.

[0069] A higher signal strength value (e.g., larger or more positive RS SI value) may indicate a stronger signal than a lower signal strength value (e.g., smaller or less positive RS SI value). For example, RSSI may be measured on a scale of negative numbers (e.g, 0 decibel-milliwatts (dBm) to -100 dBm), such that an RSSI value closer to zero may indicate a stronger signal than an RSSI value further from zero, which may indicate a weaker signal. The RSSI values may be logarithmic values. OdBm may be equal to ImW of transmit power. The power involved in transmissions on the communication link may be less than ImW of transmit power. A power level and distance relationship may be inferred, and a system of notification characteristics may be configured for the audible signal strength notification that increase SPL to compensate for distance (e.g., and to indicate greater perceived urgency). The audible signal strength notification may also, or alternatively, increase in frequency and recurrence to infer perceived urgency, where urgency level increases with a weaker signal strength or further distance.

[0070] In one example in which the communication link comprises BLUETOOTH or BLUETOOTH Low Energy communications, the communication link may have a maximum range of about 10 meters. Table 1 below provides an exemplary configuration of RSSI values that may be used as signal strength thresholds at which different audible signal strengthMatter No. P39445 -WOnotifications may be triggered for being provided at the central medical monitoring device. Table 1 also identifies an inferred distance based on the RSSI value, that may be stored in the configuration and / or for which the corresponding audible signal strength notification may be provided.TABLE 1>

[0071] Though specific values are provided for signal strength thresholds and / or SPL levels for providing corresponding audible signal strength notifications, these are merely examples. Other SPL values may be provided, which may be based on the type of central medical monitoring device (e.g., between ~94 and 105 dBA may be implemented for certain mobile phones or devices). Also, though RSSI is provided as a measurement of signal strength, other measurements of signal strength may be implemented. The RSSI value alone may not directly correspond to the physical distance between the device and the RF antenna, as the RF communication signal on the communication link can be influenced by various environmentalMatter No. P39445 -WOand / or hardware factors. Though SPL may be provided as an example of a type of audible signal strength notification, other types of signal strength notifications may be similarly configured.

[0072] In one example, the audible signal strength notification may sound once each time the signal strength measured between the central medical monitoring device and the peripheral medical monitoring device meets a corresponding signal strength threshold. As signal strength increases or decreases between signal strength thresholds, the corresponding audible signal strength notification may be provided. The central medical monitoring device may calculate the signal strength for each received transmission. When the signal strength changes over the threshold ranges within a predefined period of time, the audible signal strength notification may traverse through the ranges of Tabel 1 (e.g., in a matter of seconds). To avoid unnecessary notifications, each audible signal strength notification may be implemented to be set off for predefined periods of time that are each a subset of an estimated period of time over which the signal may be predicted to change (e.g., each audible signal strength notification may be provided for about .7 seconds where the estimated period of time over which the signal may be predicted to change is 5 seconds).

[0073] The level and / or type (e.g., different types of sensory channels) of the signal strength notifications may change or be maintained based on the signal strength reaching a predefined level corresponding to the level and / or type of signal strength notification. For example, the signal strength notifications may be configured to be provided via different sensory channels. For example, one or more of the signal strength notifications that correspond to one or more of the stronger signal strength thresholds may be visible signal strength notifications. As the signal strength gets weaker and reaches one or more other signal strength thresholds, the signal strength notifications may transition to audio signal strength notifications. When the signal strength (e.g., RSSI value) is relatively higher, a visible signal strength notification may be provided comprising a graphical user interface comprising information giving the user feedback. The display of the visible signal strength notification may presume the display of the central medical monitoring device may be viewed by the user. However, the display may be unable to be seen at certain distances at which the signal strength may trigger certain thresholds for providing the signal strength notification, which may prevent or diminish the effectiveness of the visible signal strength notification. Thus, at a certain signal strength threshold the type of signalMatter No. P39445 -WOstrength notification may transition from a visible signal strength notification to an audio or haptic signal strength notification.

[0074] In one embodiment, the signal strength threshold at which the signal strength of the communication link between the central medical monitoring device and the peripheral medical monitoring device is strongest may trigger a visible signal strength notification. A next signal strength threshold may trigger an audio signal strength notification. As the signal strength weakens to other signal strength thresholds, the audio signal strength notification may increase in level, as described herein. As the signal strength gets stronger, the audio signal strength notification may decrease in level until transitioning back to the visible signal strength notification.

[0075] Referring again to FIG. 3A, the central medical monitoring device may detect, at 306, that the signal strength of the connection with the peripheral medical monitoring device is below an initial threshold and provide a visible signal strength notification at 308. There may be a predefined threshold that is stored at the central medical monitoring device for triggering each of the visible signal strength notification and the audible signal strength notification, such that the central medical monitoring device may transition from providing the visible signal strength notification to the audible signal strength notification, and vice versa. Instead of transitioning to the audible signal strength notification, the audible signal strength notification may be added to or removed from the visible signal strength notification. In one example, the signal strength threshold for triggering the visible signal strength notification may be the strongest or initial signal strength threshold and the signal strength threshold triggering the audible signal strength notification may be the next weakest or next level signal strength threshold, but the thresholds may be configured differently. When the signal strength is determined to decrease below a lower-quality signal strength threshold for triggering the audible signal strength notification at 310, the central medical monitoring device may provide an audible signal strength notification at 318. As the signal strength continues to decrease below lower-quality signal strength thresholds at 310, the central medical monitoring device may decrease the level of the audible signal strength notification and / or provide a lower quality signal strength notification via another sensory channel at 318. As the signal strength is determined to increase above higher-quality signal strength thresholds at 312, the central medical monitoring device may increase the level of the audible signal strength notification and / or provide a higher quality signal strength notificationMatter No. P39445 -WOvia another sensory channel at 318. When the signal strength is determined to reach the predefined threshold (e.g., strongest signal strength threshold) for triggering the visible signal strength notification again, the central medical monitoring device may display the visible signal strength notification at 318.

[0076] The central medical monitoring device, the peripheral medical monitoring device, and / or another computing device may be used to provide haptic feedback to the user when certain signal strength thresholds are identified for triggering the signal strength notification. For example, the weaker signal strength threshold or thresholds (e.g., 90 dBm to -100 dBm) may trigger haptic feedback via the central medical monitoring device, the peripheral medical monitoring device, and / or another computing device. The haptic signal strength notifications may be implemented at the weaker signal strength thresholds than the visible signal strength notifications and / or audible signal strength notifications (e.g. signal strength thresholds at which the visible signal strength notifications and / or audible signal strength notifications may be less effective or ineffective).

[0077] Referring again to FIG. 3A, the central medical monitoring device may detect, at 306, that the signal strength of the connection with the peripheral medical monitoring device is below an initial threshold and provide a visible signal strength notification and / or an audible signal strength notification at 308. When the signal strength is determined to decrease below a lower-quality signal strength threshold at 310, the central medical monitoring device may continue to provide visible and / or audible signal strength notifications at different levels at 318. There may be a predefined threshold that is stored at the central medical monitoring device for triggering the haptic signal strength notification, such that the central medical monitoring device may transition from providing the visible signal strength notification and / or the audible signal strength notification to the haptic signal strength notification, and vice versa. Instead of transitioning to the haptic signal strength notification, the haptic signal strength notification may be added to or removed from the other signal strength notifications. As the signal strength is determined to decrease below a predefined lower-quality signal strength threshold at 310, the central medical monitoring device may cause the haptic signal strength notification to be provided at 318. The haptic signal strength threshold may be provided locally, or the central medical monitoring device may send a message to another device, such as the peripheral medical monitoring device, a wearable device, and / or another computing device. When the signalMatter No. P39445 -WOstrength is determined to increase above the predefined lower-quality signal strength threshold for providing the haptic signal strength notification, at 312, the central medical monitoring device may cause the haptic signal strength notification to stop being provided and may revert back to providing the audible signal strength notification and / or the visible signal strength notification (e.g., depending on the signal strength and the corresponding threshold). The central medical monitoring device may cause the peripheral medical monitoring device, the wearable device, and / or the other computing device to stop providing the haptic feedback by sending a message, or may stop providing the haptic feedback locally.

[0078] In order to provide the haptic feedback at the peripheral medical monitoring device, the peripheral medical monitoring device may include a haptic actuator or vibration motor, which may cause the peripheral medical monitoring device to include additional hardware components that may increase power consumption on a resource-limited medical monitoring device. To prevent additional power consumption at the peripheral medical monitoring device, the central medical monitoring device may provide the haptic notification or the message may be sent to another wearable device or another computing device for providing the haptic notification. The wearable device or another computing device may also, or alternatively, be implemented to provide the visible signal strength notifications and / or audible signal strength notifications to offload resources from being used at the central medical monitoring device or the peripheral medical monitoring device. For example, the central medical monitoring device may monitor a power level locally or at the peripheral medical monitoring device (e.g., via status messages received from the peripheral medical monitoring device) and may send a message to the wearable device and / or another computing device to provide the signal strength notification when the central medical monitoring device or the peripheral medical monitoring device are below a defined power threshold.

[0079] The level and / or type e.g., different type of sensory channels) of the signal strength notifications may change or be maintained based on the rate of change of the signal strength over a period of time may indicate a type of interference that is affecting the change in signal strength, and the level and / or type of signal strength notification may be changed or maintained to be more effective for the indicated type of interference. For example, a rate of change above a certain threshold within a predefined period of time (e.g., one or two seconds)Matter No. P39445 -WOmay indicate a physical or electromagnetic obstruction may be the cause of interference or the decrease in the signal strength.

[0080] The central medical monitoring device may calculate the rate of change of the signal strength within a predefined period of time to determine whether to make a change to the type of signal strength notification being provided or maintain the current type of signal strength notification being provided. The signal strength may be calculated based on each received communication or at least a number of communications with a predefined period of time (e.g., each second or at least every 20 seconds) before a continuous connection is dropped (e.g., a supervision timeout threshold). If the signal strength is decreased or increased with a certain rate within a period of time (e.g., one or two seconds), the change in signal strength may indicate a physical or electromagnetic obstruction may be the cause of interference or the decrease / increase in the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device. Thus, the distance between the central medical monitoring device and the peripheral medical monitoring device may be sustained or be relatively similar, which may mean that the type of signal strength notification being provided may be maintained. As such, the central medical monitoring device may provide a signal strength notification and, based on the rate of change of the signal strength, maintain the current signal strength notification. In an example, a visible signal strength notification may be maintained on the display of the central medical monitoring device and be effective in notifying the user of the change in signal strength due to the indication based on the rate of change, even though the overall signal strength may drop below a threshold set for transitioning to the audible signal strength notification or the haptic signal strength notification. However, if the rate of change is maintained within the predefined period of time (e.g., indicating there is a progressive / constant or near constant rate of change in the signal strength and that the central medical monitoring device or the peripheral medical monitoring device moving away from one another), then the type of signal strength notification may be changed based on the signal strength thresholds and the corresponding type of signal strength notification.

[0081] FIG. 3B is a flow diagram illustrating an example process 350 for providing signal strength notifications to a user based on a rate of change of the signal strength between the central medical monitoring device and the peripheral medical monitoring device. One or more portions of the process 350 may be performed by one or more computing devices. For example,Matter No. P39445 -WOthe one or more portions of the process 350 may be performed by central medical monitoring devices, such as mobile device 104 shown in FIGs. 1A and IB. One or more portions of the process 350 may be performed by a peripheral medical monitoring device, such as a glucose monitoring device or another analyte monitoring device. One or more portions of the process 350 may be stored in memory as computer-readable or machine-readable instructions that may be executed by a processor of the one or more computing devices. Though portions of the process 350 may be described herein as being performed by a particular computing device, such as a central medical monitoring device, the process 350 or portions thereof may be performed by another computing device or distributed across multiple computing devices, such as one or more central medical monitoring devices (e.g., mobile devices, remote computing devices, or other central medical monitoring devices), peripheral medical monitoring devices (e.g., analyte monitoring devices), and / or one or more other devices. Though the process 350 may illustrate a sequence of steps or events in a particular order, the sequence of steps or events may be performed in another order.

[0082] Similar portions of the procedure 350 may be performed as described in the procedure 300 shown in FIG. 3A. For example, as shown in FIG. 3B, at 302, a wireless connection may be established on a wireless communication link between a central medical monitoring device and a peripheral medical monitoring device. At 304, the central medical monitoring device may monitor the signal strength of the connection between itself and the peripheral medical monitoring device. At 306, the central medical monitoring device may determine whether the signal strength of the connection to the peripheral medical monitoring device is below an initial threshold. If the signal strength of the connection with the peripheral medical monitoring device is not below the initial threshold at 306, the central medical monitoring device may continue monitoring the connection status at 304. If the signal strength of the connection with the peripheral medical monitoring device is below the initial signal strength threshold at 306, the central medical monitoring device may provide a signal strength notification at 308. The central medical monitoring device may continue to provide signal strength notifications when the signal strength of the connection with the peripheral medical monitoring device corresponds to a given signal strength threshold. For example, the signal strength notification may include a signal strength notification on one or more sensory channels, such as an audible signal strength notification, visible signal strength notification, haptic signalMatter No. P39445 -WOstrength notification, and / or another signal strength notification configured to provide notification, as described herein. As described herein, there may be a predefined threshold that is stored at the central medical monitoring device for triggering each level and / or type of signal strength notification.

[0083] As shown in FIG. 3B, the central medical monitoring device may consider the rate of change of the signal strength when determining whether to adjust the level and / or type of the signal strength notification. For example, at 310, when the signal strength is determined to decrease below a lower-quality signal strength threshold for triggering a change in the level or type of notification, the central medical monitoring device may analyze the rate of change of the signal strength threshold over a period of time to determine whether to adjust the level or type of the signal strength notification at 352. The central medical monitoring device may maintain the type and / or level of the signal strength notification when the rate of change of the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device is determined at 352 to be increasing at a rate greater than the rate of change threshold. If the signal strength has decreased at a certain rate within a period of time (e.g., one or two seconds), the change in signal strength may indicate a physical or electromagnetic obstruction may be the cause of interference or the decrease in the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device. From this, the central medical monitoring device may infer that the physical or electromagnetic obstruction is the cause of the decrease in signal strength. Thus, the central medical monitoring device may determine that the distance between the central medical monitoring device and the peripheral medical monitoring device may be sustained or be relatively similar, which may mean that the level and / or type of signal strength notification being provided may be maintained. As such, the central medical monitoring device may maintain the current signal strength notification based on the rate of change of the signal strength.

[0084] If the rate of change is determined to be below the rate of change threshold at 352 within the predefined period of time (e.g. , maintained or maintained within a predefined margin or threshold indicating there is a progressive / constant or near constant rate of change in the signal strength and that the central medical monitoring device and the peripheral medical monitoring device moving away from one another), then the level and / or type of signal strengthMatter No. P39445 -WOnotification may be adjusted at 318 based on the signal strength thresholds and the corresponding type of signal strength notification for the current signal strength.

[0085] When the rate of change of the signal strength is below the rate of change threshold, the central medical monitoring device may adjust the type and / or level of the signal strength notification at 318. For example, the type of signal strength notification may be changed from the visible signal strength notification to the audible signal strength notification. Though the visible signal strength notification and the audible signal strength notification are provided as examples, the rate of change threshold may be considered prior to any adjustment of the level and / or notification type (e.g., using different sensory channel) of the signal strength notification. Prior to adjusting the level and / or notification type (e.g., using different sensory channel) of the signal strength notification at 318, the central medical monitoring device may determine, at 316, whether the level of the signal strength notification is already at a highest predefined level. If so, the central medical monitoring device may maintain the current level and / or type of signal strength notification.

[0086] At 312, when the signal strength is determined to increase above a higher-quality signal strength threshold for triggering a change in the level or type of notification, the central medical monitoring device may analyze the rate of change of the signal strength threshold over a period of time to determine whether to adjust the level or type of the signal strength notification at 354. The central medical monitoring device may maintain the type and / or level of the signal strength notification when the rate of change of the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device is determined at 352 to be decreasing at a rate greater than the rate of change threshold. If the signal strength has increased at a certain rate within a period of time e.g., one or two seconds), the change in signal strength may indicate a physical or electromagnetic obstruction has been removed which may be the cause of interference or the increase in the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device. From this, the central medical monitoring device may infer that the removal of the physical or electromagnetic obstruction was the cause of the increase in signal strength. Thus, the central medical monitoring device may determine that the distance between the central medical monitoring device and the peripheral medical monitoring device may be sustained or be relatively similar, which may mean that the level and / or type of signal strength notification being provided may beMatter No. P39445 -WOmaintained. As such, the central medical monitoring device may maintain the current signal strength notification based on the rate of change of the signal strength.

[0087] If the rate of change is determined to be below the rate of change threshold at 354 within the predefined period of time (e.g., maintained or maintained within a predefined margin or threshold indicating there is a progressive / constant or near constant rate of change in the signal strength and that the central medical monitoring device and the peripheral medical monitoring device moving closer to one another), then the level and / or type of signal strength notification may be adjusted at 318 based on the signal strength thresholds and the corresponding type of signal strength notification for the current signal strength.

[0088] When the rate of change of the signal strength is below the rate of change threshold, the central medical monitoring device may adjust the type and / or level of the signal strength notification at 318. For example, the type of signal strength notification may be changed from the audible signal strength notification to the visible signal strength notification. Though the visible signal strength notification and the audible signal strength notification are provided as examples, the rate of change threshold may be considered prior to any adjustment of the level and / or notification type (e.g., using different sensory channel) of the signal strength notification. Prior to adjusting the level and / or notification type (e.g., using different sensory channel) of the signal strength notification at 318, the central medical monitoring device may determine, at 314, whether the level of the signal strength notification is above the initial signal strength threshold. If so, the central medical monitoring device may stop providing a signal strength notification and continue monitoring the signal strength at 304.

[0089] One or more sensors on the central medical monitoring device may also, or alternatively, be used to infer the type of interference. For example, the central medical monitoring device may use one or more sensors on the device to determine that the central medical monitoring device is moving or is moving at a predefined speed or distance, such that the distance between the devices may be causing the change in signal strength of the connection between the devices. For example, measurement values from an accelerometer, gyroscope, and / or global positioning system (GPS) coordinates of the central medical monitoring device over time may be used to determine a change in distance by the central medical monitoring device.Matter No. P39445 -WO

[0090] The movement of the central medical monitoring device may be detected using the accelerometer, gyroscope, and / or GPS sensors installed thereon. The accelerometer may measure the linear acceleration of the central medical monitoring device, which may be used to detect steps and overall movement. The gyroscope may measure the orientation of the central medical monitoring device. The values measured by the gyroscope may be used to determine the rotation and / or tilt of the central medical monitoring device, which may be used for determining walking patterns and balance. GPS coordinate values may be used to measure distance moved over time. These sensors may be utilized in combination to infer user activity of the central medical monitoring device. The access to the sensor values may be enabled in the settings of the central medical monitoring device in response to user input.

[0091] If movement is detected at the central medical monitoring device or is detected at a predefined speed or distance, then the central medical monitoring device may be determined to be on the user and the change in signal strength may be less likely to be due to the user walking away from the peripheral medical monitoring device (e. ., if the peripheral medical monitoring device is determined to be on the user or is installed on the user). Instead, the movement of the central medical monitoring device may indicate that the change in signal strength is due to another signal-reducing factor. The other signal reducing factors may include physical or electromagnetic obstruction, including environmental conditions such as interference or presence of other radio frequency sources; Fresnel zone obstruction; and / or hardware or network issues. The hardware issues may include problems with the transmitter of the central medical monitoring device and / or the peripheral medical monitoring device. The network issues may include network congestion or interference from other electronic devices.

[0092] FIG. 3C is a flow diagram illustrating an example process 360 for providing signal strength notifications to a user based on movement of the central medical monitoring device or a detected movement at a predefined speed or distance. One or more portions of the process 360 may be performed by one or more computing devices. For example, the one or more portions of the process 360 may be performed by central medical monitoring devices, such as mobile device 104 shown in FIGs. 1 A and IB. One or more portions of the process 360 may be performed by a peripheral medical monitoring device, such as a glucose monitoring device or another analyte monitoring device. One or more portions of the process 360 may be stored in memory as computer-readable or machine-readable instructions that may be executed by aMatter No. P39445 -WOprocessor of the one or more computing devices. Though portions of the process 360 may be described herein as being performed by a particular computing device, such as a central medical monitoring device, the process 360 or portions thereof may be performed by another computing device or distributed across multiple computing devices, such as one or more central medical monitoring devices (e.g., mobile devices, remote computing devices, or other central medical monitoring devices), peripheral medical monitoring devices (e.g., analyte monitoring devices), and / or one or more other devices. Though the process 360 may illustrate a sequence of steps or events in a particular order, the sequence of steps or events may be performed in another order.

[0093] Similar portions of the procedure 360 may be performed as described in the procedures 300, 350 shown in FIGs. 3A and 3B, respectively. For example, as shown in FIG.3C, at 302, a wireless connection may be established on a wireless communication link between a central medical monitoring device and a peripheral medical monitoring device. At 304, the central medical monitoring device may monitor the signal strength of the connection between itself and the peripheral medical monitoring device. At 306, the central medical monitoring device may determine whether the signal strength of the connection to the peripheral medical monitoring device is below an initial threshold. If the signal strength of the connection with the peripheral medical monitoring device is not below the initial threshold at 306, the central medical monitoring device may continue monitoring the connection status at 304. If the signal strength of the connection with the peripheral medical monitoring device is below the initial signal strength threshold at 306, the central medical monitoring device may provide a signal strength notification at 308. The central medical monitoring device may continue to provide signal strength notifications when the signal strength of the connection with the peripheral medical monitoring device corresponds to a given signal strength threshold. For example, the signal strength notification may include a signal strength notification on one or more sensory channels, such as an audible signal strength notification, visible signal strength notification, haptic signal strength notification, and / or another signal strength notification configured to provide notification, as described herein. As described herein, there may be a predefined threshold that is stored at the central medical monitoring device for triggering each level and / or type of signal strength notification.

[0094] As shown in FIG. 3C, the central medical monitoring device may consider the movement of the central medical monitoring device when determining whether to adjust theMatter No. P39445 -WOlevel and / or type of the signal strength notification. For example, at 310, when the signal strength is determined to decrease below a lower-quality signal strength threshold for triggering a change in the level or type of notification, the central medical monitoring device may analyze the movement of the central medical device at 362. The movement may be determined based on one or more sensor values of the sensors on the central medical monitoring device. The movement may be compared to a speed or distance threshold to determine whether the movement has changed at a rate of speed and / or over a distance exceeding the corresponding threshold. The central medical monitoring device may maintain the type and / or level of the signal strength notification when the central medical monitoring device is determined, at 362, to be moving or moving at a rate or distance greater than the corresponding threshold. If the central medical monitoring device is moving or moving at a rate or distance greater than the corresponding threshold the decrease in signal strength may indicate a physical or electromagnetic obstruction may be the cause of interference or the decrease in the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device, as the central medical monitoring device and the peripheral medical monitoring device may be inferred to be moving together. From this, the central medical monitoring device may infer that the physical or electromagnetic obstruction is the cause of the decrease in signal strength. Thus, the central medical monitoring device may determine that the distance between the central medical monitoring device and the peripheral medical monitoring device may be sustained or be relatively similar, which may mean that the level and / or type of signal strength notification being provided may be maintained. As such, the central medical monitoring device may maintain the current signal strength notification based on the movement of the central medical monitoring device or movement at a rate or distance greater than the corresponding threshold.

[0095] If movement of the central medical monitoring device fails to be detected or detected at a rate or distance greater than the corresponding threshold at 362, then the level and / or type of signal strength notification may be adjusted at 318 based on the signal strength thresholds and the corresponding type of signal strength notification for the current signal strength. When the central medical monitoring device is not moving or moving at a rate or distance greater than the corresponding threshold, the central medical monitoring device may infer that the distance between the central medical monitoring device and the peripheral medicalMatter No. P39445 -WOmonitoring device is increasing to cause the detected decrease in signal strength. As such, the central medical monitoring device may adjust the type and / or level of the signal strength notification at 318. For example, the type of signal strength notification may be changed from the visible signal strength notification to the audible signal strength notification. Though the visible signal strength notification and the audible signal strength notification are provided as examples, the movement of the central medical monitoring device may be considered prior to any adjustment of the level and / or notification type (e.g., using different sensory channel) of the signal strength notification. Prior to adjusting the level and / or notification type (e.g., using different sensory channel) of the signal strength notification at 318, the central medical monitoring device may determine, at 316, whether the level of the signal strength notification is already at a highest predefined level. If so, the central medical monitoring device may maintain the current level and / or type of signal strength notification.

[0096] At 312, when the signal strength is determined to increase above a higher-quality signal strength threshold for triggering a change in the level or type of notification, the central medical monitoring device may analyze the movement of the central medical monitoring device to determine whether to adjust the level or type of the signal strength notification at 364. The central medical monitoring device may maintain the type and / or level of the signal strength notification when the central medical monitoring device is determined at 352 to be moving or moving at a rate or distance greater than the corresponding threshold. If the central medical monitoring device is moving or moving at a rate or distance greater than the corresponding threshold, the increase in signal strength may indicate the removal of a physical or electromagnetic obstruction may be the cause of interference, as the central medical monitoring device and the peripheral medical monitoring device may be inferred to be moving together. From this, the central medical monitoring device may infer that removal of the physical or electromagnetic obstruction is the cause of the increase in signal strength. Thus, the central medical monitoring device may determine that the distance between the central medical monitoring device and the peripheral medical monitoring device may be sustained or be relatively similar, which may mean that the level and / or type of signal strength notification being provided may be maintained. As such, the central medical monitoring device may maintain the current signal strength notification based on the movement of the central medical monitoring device or movement at a rate or distance greater than the corresponding threshold.Matter No. P39445 -WO

[0097] If movement of the central medical monitoring device fails to be detected or detected at a rate or distance greater than the corresponding threshold at 364, then the level and / or type of signal strength notification may be adjusted at 318 based on the signal strength thresholds and the corresponding type of signal strength notification for the current signal strength. When the central medical monitoring device is not moving or moving at a rate or distance greater than the corresponding threshold, the central medical monitoring device may infer that the distance between the central medical monitoring device and the peripheral medical monitoring device is decreasing to cause the detected increase in signal strength. As such, the central medical monitoring device may adjust the type and / or level of the signal strength notification at 318. For example, the type of signal strength notification may be changed from the audible signal strength notification to the visible signal strength notification. Though the visible signal strength notification and the audible signal strength notification are provided as examples, the movement of the central medical monitoring device may be considered prior to any adjustment of the level and / or notification type (e.g., using different sensory channel) of the signal strength notification. Prior to adjusting the level and / or notification type e.g., using different sensory channel) of the signal strength notification at 318, the central medical monitoring device may determine, at 314, whether the level of the signal strength notification is above the initial signal strength threshold for providing signal strength notifications. If so, the central medical monitoring device may stop providing signal strength notifications and continue monitoring the signal strength at 304

[0098] The movement of the central medical monitoring device (e.g., shown in FIG. 3C) may be considered with the rate of change of the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device (e.g., shown in FIG. 3B) to determine whether to change the type or level of the signal strength notification. When the rate of change of the signal strength and the movement of the central medical monitoring device both indicate a similar type of interference (e.g., the rate of change of the signal strength of the connection is below the rate of change threshold and the central medical monitoring device is considered to be moving), the central medical monitoring device may adjust the signal strength notification at 318. For example, when the central medical monitoring device is determined to be moving and the signal strength is changing by a predefined rate of change, the central medical monitoring device may provide a visible signal strength notification. WhenMatter No. P39445 -WOthe rate of change of the signal strength and the movement of the central medical monitoring device indicate a different type of interference, the central medical monitoring device may adjust the signal strength notification at 318 or maintain the signal strength notification. The central medical monitoring device may also weight the rate of change of the signal strength, the movement of the central medical monitoring device, and / or one or more other factors to determine whether to adjust the signal strength notification or maintain the signal strength notification. If the weight is above or below a threshold, the central medical monitoring device may adjust or maintain the level and / or type of signal strength notification.

[0099] The central medical monitoring device may cause the signal strength notification to be provided on one or more other devices. For example, the central medical monitoring device may cause the signal strength notification to be provided on one or more other devices based on the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device. In an example in which the signal strength notification is provided via a visible signal strength notification, the central medical monitoring device may cause a primary display of the visible signal strength notification to be changed among one or more devices based on the signal strength of the connection between the central medical monitoring device and the peripheral medical monitoring device. The medical state (e.g., diabetic state, such as hypoglycemic state, hyperglycemic state, and / or a threshold indicating the user is approaching hypo / hyperglycemic state) of the user may also, or alternatively, be considered for causing the change of the primary display of the signal strength notification or be considered when determining the primary display of the signal strength notification. Though the medical state of the user may be described as a condition for causing a change in the primary display of the signal strength notification, the medical state of the user may be considered when determining a trigger for causing another change in the level and / or type of the signal strength notification. For example, the type of signal strength notification may be changed when the user is determined to be in an extreme medical state or approaching an extreme medical state based on analyte levels and / or one or more other conditions described herein are met.

[0100] As described herein, an analyte monitoring device, such as a glucose monitoring device, may be in wireless communication or establish a wireless connection with a central medical monitoring device, such as a mobile device of the user, which may be determined to be aMatter No. P39445 -WOprimary display for providing signal strength notifications, analyte values, and / or other health-related information to the user. However, the user may implement one or more central medial monitoring devices or mobile devices that may be capable of providing signal strength notifications to the user. For example, the user may implement multiple central medical monitoring devices having a display that are each capable of operating as the primary display on which signal strength notifications may be provided to the user. When the signal strength of the connection between the central medical monitoring device (e.g., a first central medical monitoring device) and the peripheral medical monitoring device is below a threshold (e.g., that indicates the primary display may be at least a distance from the peripheral medical monitoring device), another device (e.g., a second central medical monitoring device) may be selected as the primary display. The signal strength threshold for switching the primary display may be the same or different than the threshold for providing other levels and / or types of signal strength notifications. In an example, the primary display may be transferred to a wearable device of the user, which may be closer to the user. The primary display may be transferred to another device (e.g., the second central medical monitoring device) for a period of time, until the signal strength of the connection between the central medical monitoring device (e.g., the first central medical monitoring device) and the peripheral medical monitoring device is increased above the threshold (e.g., or another threshold that is stronger for transitioning back the primary display), and / or until input is received from the user to transfer the primary display.

[0101] As described herein, the peripheral medical monitoring device may be connected to and / or capable of connecting to different devices. For example, the peripheral medical monitoring device may be connected to and / or paired to a multiple central medical monitoring devices, such as the user’s mobile phone and / or wearable device. When the first central medical monitoring device detects that the signal strength of the connection from the peripheral medical monitoring device (e.g., indicating a relatively increased distance between the two), the first central medical monitoring device may disconnect with the peripheral medical monitoring device and / or send a message to the second central medical monitoring device. The message may trigger the second central medical monitoring device to initiate and / or establish a connection with the peripheral medical monitoring device. The message may include the signal strength value of the connection between the first central medical monitoring device and the peripheral medical monitoring device. The signal strength value of the connection between the first centralMatter No. P39445 -WOmedical monitoring device and the peripheral medical monitoring device may be used by the second central medical monitoring device to determine the signal strength threshold and / or the corresponding signal strength notification to be provided by the second medical monitoring device. The message may also, or alternatively, indicate the level and / or type of signal strength notification to be provided by the second central medical monitoring device.

[0102] After the second central medical monitoring device has established a connection with the peripheral medical monitoring device, the second central medical monitoring device may operate (e.g., temporarily or until receiving a trigger to discontinue such operation) as the primary display for providing signal strength notifications, analyte values, and / or other health-related information to the user. The second central medical monitoring device may begin receiving measured analyte values and / or other information from the peripheral medical monitoring device directly for display to the user and / or operation of the second central medical monitoring device. The second central medical monitoring device may monitor the medical state of the user and provide notifications related to the medical state (e.g, such as the user entering or approaching an extreme diabetic state, such as a hyperglycemic and / or hypoglycemic state) or other health related information of the user.

[0103] After the signal strength of communications between the first central medical monitoring device and the peripheral medical monitoring device returns to a level above the threshold that triggered the transfer of the primary display to the second central medical monitoring device or higher threshold, the first central medical monitoring device may take over the role of primary display. For example, the first central medical monitoring device may monitor messages (e.g, advertisement messages or status messages) from the peripheral medical monitoring device and can again take over as the primary display. The first central medical monitoring device may send a message to the second central medical monitoring device that causes the second central medical monitoring device to disconnect from the peripheral medical monitoring device. The first central medical monitoring device may establish a connection and operate as the primary display for providing signal strength notifications, analyte values, and / or other health-related information to the user. The first central medical monitoring device may have a larger display for providing more information to the user. In another example, the peripheral medical monitoring device may monitor the signal strength of messages (e.g., advertisement messages or other messages) from the first central medical monitoring device andMatter No. P39445 -WOinitiate the transition of the primary display to the second central medical monitoring device. For example, the peripheral medical monitoring device may disconnect from the first central medical monitoring device and establish a connection with the second central medical monitoring device. The transition of the primary display may enable continuity of information and / or notifications to be provided to the user. Each of the first central medical monitoring device and the second central medical monitoring device may operate portions of a subsystem or application for providing health-related information and / or notifications to the user.

[0104] FIG. 4 is a flow diagram illustrating an example process 400 for transferring a role of primary display between a first central medical monitoring device and a second central medical monitoring device. One or more portions of the process 400 may be performed by one or more computing devices. For example, the one or more portions of the process 400 may be performed by first central medical monitoring devices, such as mobile device 104 shown in FIGs. 1A and IB, and / or a second central medical monitoring device, such as mobile device 104a shown in FIGs. 1A and IB. One or more portions of the process 400 may be performed by a peripheral medical monitoring device, such as a glucose monitoring device or another analyte monitoring device. One or more portions of the process 400 may be stored in memory as computer-readable or machine-readable instructions that may be executed by a processor of the one or more computing devices. Though portions of the process 400 may be described herein as being performed by a particular computing device, such as a first central medical monitoring device, a second central medical monitoring device, or a peripheral medical monitoring device, the process 400 or portions thereof may be performed by another computing device or distributed across multiple computing devices, such as one or more central medical monitoring devices (c. ., mobile devices, remote computing devices, or other central medical monitoring devices), peripheral medical monitoring devices (e.g., analyte monitoring devices), and / or one or more other devices. Though the process 400 may illustrate a sequence of steps or events in a particular order, the sequence of steps or events may be performed in another order.

[0105] As shown in FIG. 4, at 402, a wireless connection may be established on a wireless communication link between a first central medical monitoring device and a peripheral medical monitoring device. For example, the first central medical monitoring device may initiate device communication by establishing a BLUETOOTH or BLUETOOTH Low EnergyMatter No. P39445 -WO(BLE) connection between the first central medical monitoring device and the peripheral medical monitoring device.

[0106] At 404, the first central medical monitoring device may monitor the signal strength of the connection between itself and the peripheral medical monitoring device. The signal strength may include an RS SI value, for example. The peripheral medical monitoring device may also, or alternatively, monitor the signal strength of the connection with the first central medical monitoring device at 404. The monitoring may involve regular checks for data packet exchanges and / or assessing connection integrity, such as verifying the presence of expected acknowledgment signals for transmitted packets.

[0107] At 406, the first central medical monitoring device and / or the peripheral medical monitoring device may determine whether the signal strength of the connection is below a primary display transfer threshold. The primary display transfer threshold may be a threshold at which a primary display for providing signal strength notifications, analyte values, and / or other health-related information to the user may be transferred to another device. The primary display transfer threshold may be the same as or different from one or more other thresholds described herein for changing a level and / or type of signal strength notification. If the signal strength of the connection is not below primary display transfer threshold at 406, the first central medical monitoring device and / or the peripheral medical monitoring device may continue monitoring the connection status at 404. The connection on the wireless communication link may remain stable, and the first central medical monitoring device may exchange data with the peripheral medical monitoring device (e.g., receiving analyte values, other health-related information, and / or notifications).

[0108] If the signal strength of the connection between the peripheral medical monitoring device and the first central medical monitoring device is determined (e.g., by the first central medical monitoring device and / or the peripheral medical monitoring device) to be below the primary display transfer threshold at 406, the role of the primary display may be transferred to another device at 408. For example, the role of the primary display may be transferred to a second central medical monitoring device. The first central medical monitoring device and / or the peripheral medical monitoring device may cause the connection between the devices to be terminated. The first central medical monitoring device and / or the peripheral medical monitoring device may cause the second medical monitoring device to establish a connectionMatter No. P39445 -WOwith the peripheral medical monitoring device. For example, the first central medical monitoring device and / or the peripheral medical monitoring device may send one or more messages to the second central medical monitoring device that is configured to cause the second central medical monitoring device to establish a connection with the peripheral medical monitoring device and operate as the primary display for providing signal strength notifications, analyte values, and / or other health-related information to the user.

[0109] At 410, the first central medical monitoring device and / or the peripheral medical monitoring device may determine whether the signal strength of communications between the first central medical monitoring device and the peripheral medical monitoring device has returned to above the primary display transfer threshold. To return the role of primary display back to the first central medical monitoring device, the threshold may be higher than the original primary display transfer threshold for transferring the role of primary display to the second central medical monitoring device. This may prevent the role from changing back and forth multiple times when the signal strength may increase and decrease to levels within a range or near the threshold. Additionally, or alternatively, the first central medical monitoring device and / or the peripheral medical monitoring device may implement the primary display transfer threshold with a hysteresis, such that the primary display transfer threshold may be increased by a predefined amount after the transfer of the role of the primary display to another device.

[0110] If, at 410, the first central medical monitoring device and / or the peripheral medical monitoring device determines that the signal strength of communications between the first central medical monitoring device and the peripheral medical monitoring device has returned to above the primary display transfer threshold or another threshold established for returning the role of primary display to the first central medical monitoring device, the role of the primary display may be transferred to the first central medical monitoring device at 414. For example, the first central medical monitoring device and / or the peripheral medical monitoring devices may monitor messages communicated between one another (e.g., advertisement messages, status messages, and / or other messages) and can transmit a message to the second central medical monitoring device to cause the second central medical monitoring device to disconnect from the peripheral medical monitoring device. The message that is sent to the second central medical monitoring device may trigger a notification to the user on the display of the second central medical monitoring device to request whether the user would like to transferMatter No. P39445 -WOthe primary display. The role of primary display may be transferred automatically or in response to input from the user to transfer the role of primary display. In response to the message, the second central medical monitoring device may disconnect from the peripheral medical monitoring device and the first central medical monitoring device may connect to the peripheral medical monitoring device for operating as the primary display for providing signal strength notifications, analyte values, and / or other health-related information to the user. In one example in which the peripheral medical monitoring device may maintain a dual connection with each of the first medical monitoring device and the second medical monitoring device, a message may be sent between the devices to update the role and operation of the device operating as the primary display without causing a disconnection / connection update between devices.[0U1] If, at 410, the first central medical monitoring device and / or the peripheral medical monitoring device determine that the signal strength of communications between the first central medical monitoring device and the peripheral medical monitoring device has remains below the primary display transfer threshold or another threshold established for returning the role of primary display to the first central medical monitoring device, the role of the primary display may be maintained by the second central medical monitoring device at 412 for providing health-related information and / or notifications to the user.

[0112] In one example, the central medical monitoring device that is connected to the peripheral medical monitoring device may detect that the signal strength of the connection is below a transmission power boost threshold, which may be the same or different threshold than the primary display transfer threshold and / or one or more other signal strength thresholds described herein, and send a message to the peripheral medical monitoring device to cause the peripheral medical monitoring device to increase a transmission power to compensate for the decrease in signal strength of the connection. The message configured to cause an increase in transmission power may be sent instead of, or in addition to, providing one or more notifications or transferring the role of the primary display, as described herein. The message may be transmitted to the peripheral medical monitoring device to retain proper signal strength to maintain a connection for a predefined period of time and / or until a subsequent message is transmitted to the peripheral medical monitoring device.

[0113] Providing notifications and / or increasing the transmit power of devices may cause the devices to utilize additional power. As the central medical monitoring device and / or theMatter No. P39445 -WOperipheral medical monitoring device may be power restricted or limited devices operating on battery power or a limited / restricted power source, the notifications and / or increases in transmission power may be implemented in an energy efficient manner to help with resource management on the central medical monitoring device and / or the peripheral medical monitoring devices. For example, the central medical monitoring device and / or the peripheral medical monitoring device may provide an audible notification in advance of providing a visible notification or causing the peripheral medical monitoring device to increase its transmit power, as the audible notification may utilize less power. The audible notification may cause the user to move the peripheral medical monitoring device and the central medical monitoring device closer to each other and avoid the need for performing actions that may utilize greater amounts of power at the devices. The notifications may be provided at the central medical monitoring device prior to performing notifications via the peripheral medical monitoring device or causing the peripheral medical monitoring device to increase a transmission power, as the central medical monitoring device may have a larger battery or power capacity than the peripheral medical monitoring device.

[0114] Different signal strength thresholds are described herein as conditions operating as triggering criteria for causing an action, such as a notification to be provided at one or more devices, transferring of a role of primary display between devices, and / or causing the peripheral medical monitoring device to increase its transmit power. Though these signal strength thresholds are provided as example conditions that operate as triggering criteria for performing a corresponding activity when met, alternative or additional conditions may be met for triggering the notifications, to transfer the role of primary display, and / or to cause the peripheral medical monitoring device to increase its transmit power. For example, in order to perform certain actions described herein in response to detection of a signal strength of a connection being below a threshold, the central medical monitoring device and / or the peripheral medical monitoring device may be determined to be above or below a battery power threshold. Additionally, or alternatively, in order to perform certain actions described herein in response to detection of a signal strength of a connection being below a threshold, a user may be determined to be in a certain medical state (e.g., a hypoglycemic or hyperglycemic state) or have an analyte level above or below a certain threshold e.g., a threshold indicating the user is in a hypoglycemic or hyperglycemic state, or trending toward a hypoglycemic or hyperglycemic state).Matter No. P39445 -WO

[0115] Other conditions may also be considered for performing one or more actions described herein. For example, the user may select an option that one or more of the actions described herein (e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) be performed when contextual conditions are met in addition to the signal strength threshold. The contextual conditions may include time frames in which the peripheral medical monitoring device, the central medical monitoring device, and / or the user may benefit from the peripheral medical monitoring device and the central medical monitoring device having at least a threshold level of signal strength for communications and / or be within a threshold proximity to one another.

[0116] In one example, the contextual conditions may include an analyte level, or a predictive analyte level, of the user going above or below a threshold (e.g, above a high-end threshold or below a low-end threshold) indicating the user is approaching or has reached a certain medial state (e.g, hypoglycemic or hyperglycemic state). The actions described herein (e.g, providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may enable or assist the user in monitoring their analyte levels until the analyte levels are back within a predefined range (e.g., for a period of time). When the analyte levels are back within a predefined range, the actions described herein (e.g, providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may be less beneficial and may be prevented from occurring to save on processing and / or power resources at the central medical monitoring device and / or the peripheral medical monitoring device.

[0117] The contextual conditions may include the analyte level (e.g, glucose level) of the user increasing or decreasing at a rate of change that is greater than a threshold within a period of time (e.g., one minute, five minutes, ten minutes, fifteen minutes, thirty minutes, etc. . The rate of change of the analyte level of the user may be considered together with or irrespective of the current analyte level of the user. The actions described herein (e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase itsMatter No. P39445 -WOtransmit power based on signal strength) may enable or assist the user in monitoring their analyte levels until the rate of change of the analyte levels are back at a predefined rate of change that is less than the threshold. When the analyte levels are back at an acceptable rate of change (e.g., less than the threshold and / or for a period of time), the actions described herein (e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may be less beneficial and may be prevented from occurring to save on processing and / or power resources at the central medical monitoring device and / or the peripheral medical monitoring device.

[0118] The contextual conditions may include a period of time or a time of day. For example, the monitoring of certain analyte levels for certain medical conditions may have greater importance at specific times of day or at times of day relative to certain user activity for treating or assisting the user in treating the medical condition. In the example of the user having a diabetic condition, mealtimes and / or times of increased activity (e.g., exercise) may have greater importance for monitoring the analyte levels of the user. The mealtimes and / or times of increase activity may be predefined, based on input from the user, and / or automatically determined. The central medical monitoring device may receive an indication of a mealtime or a time of a meal from user input (e.g., logging into an electronic log stored in memory, a calendar input on an electronic calendar on the central medical monitoring device, etc ). The central medical monitoring device may receive an indication of increased user activity from user input (e.g., logging into an electronic log stored in memory, a calendar input on an electronic calendar on the central medical monitoring device, etc.) and / or one or more sensors (e.g., gyroscope, accelerometer, etc} on the central medical monitoring device and / or peripheral medical monitoring device. The periods of time or time of day may be periods during or after which a form of treatment (e.g., bolus of insulin or other treatment) may be implemented or scheduled. The central medical monitoring device may receive an indication of treatment from user input (e.g., logging into an electronic log stored in memory). The central medical monitoring device may receive other indications from user input (e.g., logging into an electronic log stored in memory) that may affect the analyte levels and / or medical condition of the user (e.g., stress, illness, treatment / medication, etc . The actions described herein ((e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based onMatter No. P39445 -WOsignal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may enable or assist the user in monitoring their analyte levels during and / or after an occurrence of an event (e.g., for an hour, two hours, three hours, five hours, etc. after a mealtime, time of increased activity, and / or treatment of the medical condition) that may affect analyte levels and / or the user’s medical condition, such as mealtimes, times of increased activity, treatment of the medical condition, times of increased stress or illness.Outside of these timeframes around particular events, the actions described herein (e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may be less beneficial and may be prevented from occurring to save on processing and / or power resources at the central medical monitoring device and / or the peripheral medical monitoring device.

[0119] The contextual conditions may include a status of one or more devices. For example, the contextual conditions may be based on a status of one or more treatment devices configured to treat the medical condition of the user. In the example in which the medical condition of the user includes a diabetic condition, a treatment device may include an insulin pump. The actions described (e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may enable or assist the user in monitoring their analyte levels during certain states of a treatment device. For example, the actions described herein ((e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may be provided during an error state (e.g., during a detected malfunction, such as occlusion, a mechanical error, an electronic error, a communication error, and / or another malfunction). The detected error or malfunction may be communicated from the treatment device to the central medical monitoring device. The central medial monitoring device may provide one or more of the notifications described herein in response to the detected error or malfunction at the treatment device. In another example, the notifications described herein may be performed by the treatment device itself and / or the peripheral medical monitoring device. In another example, the error state of the treatment device may be inferred or detected from theMatter No. P39445 -WOanalyte levels of the user (e.g., analyte levels going above a predefined threshold or below a predefined threshold).

[0120] The status of the one or more devices may include a status of the peripheral medical monitoring device. The actions described herein (e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may be prevented from being performed when the peripheral medical monitoring device is in an initial connected state or “warmup” state for a period of time after initial connection and / or implementation. In the example in which the medical condition of the user includes a diabetic condition, the peripheral medical monitoring device may be a glucose monitoring device (e.g., CGM or other glucose monitoring device) that is configured with an initial connected state or “warmup” state for calibrating one or more sensors thereon for performing measurements. During this time, the actions described herein (e.g., providing notifications based on signal strength, transferring of a role of primary display between devices based on signal strength, and / or causing the peripheral medical monitoring device to increase its transmit power based on signal strength) may be prevented from being performed, as the peripheral medical monitoring device may be performing calibration.
