Description

[Technical Field]

[0001] This application claims priority to Korean Patent Application No. 10-2023-0070642, filed with the Korean Intellectual Property Office on June 1, 2023, the disclosure of which is incorporated herein by reference. The present disclosure relates to an analyte monitoring device, and more particularly, to a continuous glucose monitoring (CGM) device and a control method thereof. [Background technology]

[0002] A continuous glucose monitoring system (CGMS) is a system that acquires a user's blood glucose concentration using a sensor in contact with the user's bodily fluid (e.g., interstitial fluid) and provides the acquired blood glucose concentration to the user. A CGM system includes a CGM device attached to the user's body to sense signals from the user's bodily fluid, and a user terminal device that provides the blood glucose concentration to the user.

[0003] A CGM device includes a sensor electronics unit including a battery and an analyte sensor inserted into the user's skin. Existing CGMs have a configuration in which the sensor electronics unit and the analyte sensor are structurally / electrically separated to prevent battery consumption before actual use. Herein, the sensor electronics unit and the analyte sensor are combined while the user wears the CGM device on their body, thereby setting up an electrical connection between the sensor electronics unit and the analyte sensor.

[0004] However, this structure requires a structure that combines the sensor electronics unit and the analyte sensor, which limits the simplification of the structure of the CGM device and the ease of manufacturing the CGM device.

[0005] Therefore, there is a need for a CGM device that has a simpler structure while preventing excessive battery consumption in actual use. Summary of the Invention

[0013] The at least one processor may not perform signal processing on the analyte signal while activating the communication interface at the predetermined first time interval, and the signal processing may include at least one of analog-to-digital conversion, noise filtering, and calibration.

[0014] If the strength of the first signal is less than a preset value or if the authentication fails, the at least one processor may activate the communication interface for the predetermined first time interval without establishing the communication channel.

[0015] If the strength of the first signal is less than the preset value, the at least one processor may not perform the authentication.

[0016] The first time interval may be shorter than the second time interval.

[0017] The at least one processor may transmit calibration information used to correct the analyte signal to the user terminal device over the communication channel.

[0019] The first signal may include first identification information for establishing the communication channel, and the step of establishing the communication channel may be performed based on whether the first identification information matches second identification information pre-stored in the memory.

[0020] The step of performing the authentication may include: demodulating a first portion of the packet of the first signal modulated based on on-off keying (OOK) to obtain a first value; and determining that the authentication is successful if the first value matches a second value pre-stored in the memory.

[0022] If the strength of the first signal is less than the preset value, the authentication may not be performed.

[0023] The control method may further include transmitting, over the communication channel, calibration information to the user terminal device for use in correcting the analyte signal.

[0027] A brief explanation of terms used herein will be given before describing the present disclosure in detail.

In addition, in the drawings, in order to clearly explain the present disclosure, parts unrelated to the description will be omitted, and similar reference numerals will be used throughout the specification to describe similar parts.

[0033] FIG. 1 is a schematic diagram illustrating a continuous glucose monitoring (CGM) system, according to one embodiment of the present disclosure.

[0034] 1 , an analyte monitoring system 1000 may include an analyte monitoring device 100 and a user terminal device 200. For example, the analyte monitoring system 1000 may be a CGM system (CGMS), and the analyte monitoring device 100 may be a CGM device. The user terminal device 200 may be a smartphone, a tablet PC, a smartwatch, a personal digital assistant (PDA), or a dedicated receiver (e.g., a receiver).

[0035] The analyte monitoring device 100 may obtain information regarding the concentration of an analyte in the bodily fluid of the user 1. The analytes may include glucose and ketones. The information regarding the analyte concentration may include a signal magnitude related to the analyte concentration and a value representing the concentration.

[0036] Analyte monitoring device 100 may be attached to the body of user 1. At least a portion of analyte monitoring device 100 may be inserted into the skin of user 1 and placed inside the body of user 1.

[0037] The user terminal device 200 may receive information regarding the concentration of the analyte from the analyte monitoring device 100. The user terminal device 200 may provide the information regarding the concentration of the analyte to a user. The user terminal device 200 may provide the information regarding the concentration of the analyte on a display. The information regarding the concentration of the analyte provided to the user may include data processed as a signal by the user terminal device 200. For example, the user terminal device 200 may apply a predefined algorithm to the signal sensed by the analyte monitoring device 100 to generate a blood glucose concentration value.

[0038] Figures 2A, 2B, and 2C are schematic diagrams showing an analyte monitoring device according to a first, second, and third embodiment inserted into a user's skin, respectively.

[0039] 2A-2C, analyte monitoring device 100 may include analyte sensor 110 and sensor electronics unit 120. Analyte sensor 110 and / or sensor electronics unit 120 may be powered by applicator 10. Analyte sensor 110 may be inserted into a user's skin S by applicator 10.

[0040] In the first and third embodiments, the applicator 10 may move the analyte sensor 110 and the sensor electronics unit 120. In the second embodiment, the applicator 10 may move the analyte sensor 110. For example, in the first embodiment, the analyte monitoring device 100 may be placed at a first position within the applicator 10, spaced a predetermined distance from the skin S. When the applicator 10 is operated by the user, the applicator 10 may move the analyte monitoring device 100 to a second position.

[0041] The applicator 10 may be operated by a user while one open side of the applicator 10 is in close contact with the skin S. The applicator 10 may include a needle (not shown) formed to surround one end of the analyte sensor 110 therein, a first elastic member (not shown) that presses the needle and one end of the analyte sensor 110 together against the skin S, and a second elastic member (not shown) for withdrawing only the needle. The needle and one end of the analyte sensor 110 may be simultaneously inserted into the skin S by decompressing the first elastic member (not shown), which is disposed in a compressed state inside the applicator 10. Once one end of the analyte sensor 110 is inserted into the skin S, the needle may be withdrawn by decompressing the compressed second elastic member (not shown), and the analyte sensor 110 may remain inserted into the skin S.

[0042] An adhesive tape may be provided on the body-contacting surface of sensor electronics unit 120 so that sensor electronics unit 120 may be fixedly attached to body skin S. Accordingly, when applicator 10 is spaced apart from body skin S, sensor electronics unit 120 may be fixedly attached to body skin S by the adhesive tape.

[0043] In a first embodiment, the analyte monitoring device 100 may include a button B for electrically connecting the analyte sensor 110 and the sensor electronics unit 120. Before a user presses button B, the sensor electronics unit 120 may be in an open-circuit state. Additionally, the analyte sensor 110 may be spaced apart from and not electrically connected to the sensor electronics unit 120. When a user presses button B, the analyte sensor 110 may be electrically connected to the sensor electronics unit 120, forming a closed circuit. In response, a battery included in the sensor electronics unit 120 may provide power to other components of the sensor electronics unit 120 (e.g., a communication interface).

[0044] In a second embodiment, the analyte monitoring device 100 may not include button B. In this case, the analyte sensor 110 may be coupled to the sensor electronics unit 120 in an open circuit state by the applicator 10. A closed circuit may be formed by coupling the analyte sensor 110 and the sensor electronics unit 120. Accordingly, a battery included in the sensor electronics unit 120 may provide power to the other components of the sensor electronics unit 120.

[0045] In a third embodiment, the analyte sensor 110 and the sensor electronics unit 120 may be initially coupled and electrically connected before operation of the applicator 10. The sensor electronics unit 120 may perform operations for communication connection with the user terminal device 200 while operating in a sleep mode using minimal power.

[0046] Analyte monitoring device 100 according to the third embodiment may have a simpler structure than the first and second embodiments. For example, analyte sensor 110 and sensor electronics unit 120 may be manufactured integrally because there is no need to move analyte sensor 110 during use by user 1 to couple / connect analyte sensor 110 to sensor electronics unit 120. Accordingly, the third embodiment may be less difficult or expensive to manufacture compared to the first and second embodiments.

[0047] For the analyte monitoring device 100 according to the third embodiment, a control method is needed to prevent excessive battery consumption because the battery is consumed before the user 1 uses the analyte monitoring device 100. For example, a sleep mode may be applied to the analyte monitoring device 100. Sleep mode (or low power mode) refers to a mode in which the analyte monitoring device 100 operates using only minimal power. In sleep mode, some operations that the analyte monitoring device 100 performs in connected mode may not be performed. For example, in sleep mode, the analyte monitoring device 100 may not perform signal processing on the analyte signal acquired using the analyte sensor 110. Additionally, to reduce power consumption, the analyte monitoring device 100 may intermittently activate a communication interface in sleep mode to wait for transmission of a wake-up signal from the user terminal device 200.

[0048] The following describes the operation and control method of the analyte monitoring device 100 in relation to the sleep mode. Meanwhile, as an example, the sleep mode is applied to the analyte monitoring device 100 according to the third embodiment, but it should be noted that the embodiment to which the sleep mode according to the present disclosure is applied is not limited to the third embodiment. In other words, the sleep mode may be applied to the analyte monitoring device 100 according to the first or second embodiment to contribute to reducing battery consumption.

[0049] FIG. 3 is a flowchart of a method for controlling an analyte monitoring device according to one embodiment of the present disclosure.

[0050] 3 , the analyte monitoring device 100 may activate the communication interface at a predetermined first time interval (S310). In this case, the analyte monitoring device 100 may operate in a first mode. The first mode may be a sleep mode (or low-power mode). The analyte monitoring device 100 may wait for reception of a radio frequency (RF) signal in a specific frequency band (e.g., 2.4 GHz). The communication interface may include an RF receiver for receiving the RF signal. Meanwhile, the first time interval may be preset to a value that can prevent excessive battery consumption of the analyte monitoring device 100 while enabling a smooth communication connection between the analyte monitoring device 100 and the user terminal device 200.

[0051] When a first signal is received from the user terminal device, the analyte monitoring device 100 may perform authentication of the first signal (S320). The first signal may be a wake-up signal. The wake-up signal may be modulated according to an on-off keying (OOK) method. The wake-up signal packet (or wake-up packet) may include a first portion modulated based on OOK. The analyte monitoring device 100 may obtain a first value by demodulating the first portion. The analyte monitoring device 100 may determine whether the first value matches a second value pre-stored in memory. The first value may be generated using an application (e.g., a dedicated app for CGM) installed on the user terminal device 200 and compatible with the analyte monitoring device 100. The second value may be a value pre-set by a manufacturer and stored in the memory of the analyte monitoring device 100.

[0052] If the first value and the second value match, the analyte monitoring device 100 may determine that authentication of the wake-up signal has been successful. If the first value and the second value do not match, the analyte monitoring device 100 may determine that authentication of the wake-up signal has failed. That is, the analyte monitoring device 100 may only be woken up through an app provided for the analyte monitoring device 100. Accordingly, the analyte monitoring device 100 may be prevented from being woken up by any device unrelated to the analyte monitoring device 100.

[0053] The analyte monitoring device 100 may determine whether the strength of the wake-up signal is greater than or equal to a preset value. If the strength of the wake-up signal is less than the preset value, the analyte monitoring device 100 may not perform authentication of the wake-up signal. Alternatively, if the strength of the wake-up signal is less than the preset value, it may be determined that authentication of the wake-up signal has failed.

[0054] The wake-up packet may include a second portion that includes identification information for the communication connection between the analyte monitoring device 100 and an external device (e.g., user terminal device 200). The identification information is information that can be used for mutual authentication between the analyte monitoring device 100 and the external device and may include, for example, a passkey.

[0055] If the first signal is successfully authenticated, the analyte monitoring device 100 may establish a communication channel between the analyte monitoring device 100 and the user terminal device 200 (S330). For example, the analyte monitoring device 100 may perform a communication connection according to the Bluetooth low energy (BLE) protocol. Specifically, the analyte monitoring device 100 may enter a second mode and transmit advertising packets to peripheral devices. The second mode may be an advertisement mode.

[0056] The advertising mode may refer to a mode in which the analyte monitoring device 100 periodically transmits an advertising signal to an external device, such as the user terminal device 200, for communication connection with the external device. In the advertising mode, the analyte monitoring device 100 may perform a broadcast to identify the user terminal device 200. The analyte monitoring device 100 may perform pairing based on the identification information received from the user terminal device 200.

[0057] The analyte monitoring device 100 may transmit information regarding the analyte signal to the user terminal device 200 at predetermined second time intervals (S340). Once the analyte monitoring device 100 is paired with the user terminal device 200, the analyte monitoring device 100 may enter a third mode. The third mode may be a connection mode. In the connection mode, the analyte monitoring device 100 may transmit information regarding the analyte signal to the user terminal device 200 at the second time intervals. The user terminal device 200 may provide the user with information regarding the received analyte signal for each second time interval.

[0058] Alternatively, the second time interval may be preset to a value that provides information about the analyte signal to a user in substantially real time. In one embodiment, the second time interval may be longer than the first time interval. For example, the first time interval may be 1 minute and the second time interval may be 5 minutes. In other embodiments, the first and second time intervals may be equal, or the first time interval may be longer than the second time interval.

[0059] On the other hand, the first time interval and / or the second time interval may be variable. For example, the first time interval and / or the second time interval may vary depending on the remaining charge of the battery 124. Specifically, as the remaining charge of the battery 124 decreases, the first time interval and / or the second time interval may increase to reduce battery 124 usage. As another example, the first time interval and / or the second time interval may vary depending on the difference between the manufacturing time of the analyte monitoring device 100 and the current time. Specifically, as the difference between the manufacturing time and the current time increases, the first time interval and / or the second time interval may increase. The analyte monitoring device 100 may measure the remaining charge of the battery 124. The analyte monitoring device 100 may measure the current time and the difference between the manufacturing time of the analyte monitoring device 100 and the current time.

[0060] The information about the analyte signal may include the magnitude of the analyte signal or a concentration value of the analyte. In the connected mode, the analyte monitoring device 100 may perform signal processing on the analyte signal. For example, the analyte monitoring device 100 may convert the analyte signal to a digital signal. The analyte monitoring device 100 may perform noise filtering on the analyte signal. Additionally, the analyte monitoring device 100 may perform a calibration on the analyte signal to calculate a concentration value of the analyte.

[0061] In this disclosure, the first, second, and third modes are used as examples of operational modes of the analyte monitoring device 100, although various other operational modes may exist. For example, a fourth mode may be an operational mode in which the analyte monitoring device 100 is not paired with the user terminal device 200 but is performing various signal processing. In this case, the analyte monitoring device 100 may sense, process, and store analyte signals in real time. Subsequently, when the operational mode of the analyte monitoring device 100 transitions to the third mode, the data stored during this period may be transmitted to the user terminal device 200.

[0062] The transition from the third mode to the fourth mode may occur periodically. For example, the analyte monitoring device 100 may transmit information about the analyte signal to the user terminal device 200 at predetermined intervals and then enter the fourth mode. The analyte monitoring device 100 may then enter the second mode and perform advertising according to a predetermined schedule.

[0063] FIG. 4 is a sequence diagram illustrating the operation of an analyte monitoring system according to one embodiment of the present disclosure.

[0064] 4, the analyte monitoring device 100 may operate in a sleep mode (S410), where the analyte monitoring device 100 may activate its communication interface for a predetermined period of time while waiting to receive a wake-up signal.

[0065] While the analyte monitoring device 100 operates in sleep mode, the user terminal device 200 may obtain a user command for a communication connection with the analyte monitoring device 100 (S415). Once the user command is obtained, the user terminal device 200 may generate a wake-up signal. In this case, the user terminal device 200 may modulate at least a portion of the wake-up signal using the OOK method. The user terminal device 200 may transmit the wake-up signal to the analyte monitoring device 100 (S420).

[0066] The analyte monitoring device 100 may determine whether the strength of the wake-up signal is greater than or equal to a preset value (S430). If the strength of the wake-up signal is greater than or equal to the preset value (S430-Y), the analyte monitoring device 100 may not perform authentication of the wake-up signal (S440). If the strength of the wake-up signal is less than the preset value (S430-N), the analyte monitoring device 100 may remain in sleep mode without performing authentication of the wake-up signal.

[0067] If the wake-up signal is successfully authenticated (S440-Y), the analyte monitoring device 100 may operate in an advertising mode (S450). In this case, the analyte monitoring device 100 may establish a communication connection with the user terminal device 200 (S460). Specifically, the analyte monitoring device 100 may perform a broadcast to identify the user terminal device 200. The analyte monitoring device 100 may perform a pairing process with the user terminal device 200. The pairing process may be performed according to the BLE protocol.

[0068] Identification information (e.g., a passkey) used in the pairing process may be included in the wake-up signal. Alternatively, the user terminal device 200 may transmit the identification information to the analyte monitoring device 100 in the communication connection process (S460). The identification information may be obtained in various ways. As an example, the identification information may be a QR code on the packaging of the analyte monitoring device 100. In this case, the user may scan the QR code using a camera of the user terminal device 200 so that the user terminal device 200 may obtain the identification information. As another example, the user may input the identification information into a user input unit of the user terminal device 200. As another example, the user terminal device 200 may receive the identification information from an external server.

[0069] Once the communication connection between the analyte monitoring device 100 and the user terminal device 200 is complete, the analyte monitoring device 100 may enter a connection mode (S470). In the connection mode, the analyte monitoring device 100 may transmit information about the analyte signal to the user terminal device 200 (S480). In the connection mode, the analyte monitoring device 100 may perform signal processing on the analyte signal acquired through the analyte sensor. The analyte monitoring device 100 may transmit the signal-processed analyte signal to the user terminal device 200.

[0070] The user terminal device 200 may provide information about the analyte signal to the user (S490). The user terminal device 200 may display the user's blood glucose level on a display. In addition, the user terminal device 200 may perform additional processing on the information about the analyte signal received from the analyte monitoring device 100. For example, if the information about the analyte signal received from the analyte monitoring device 100 is a voltage value representing the user's blood glucose level, the user terminal device 200 may apply the voltage value to a predefined algorithm to calculate the blood glucose level. The user terminal device 200 may display the calculated blood glucose level.

[0071] 4 shows that the analyte monitoring device 100 is woken up in accordance with the command of S415 to perform a communication connection operation (S460). In this manner, the command to wake up the analyte monitoring device 100 and the command for the communication connection may be formed as one. According to another embodiment, the command to wake up the analyte monitoring device 100 and the command for the communication connection may exist separately. For example, before S460, the user terminal device 200 may receive a user command for the communication connection from the user.

[0072] In the connected mode, the analyte monitoring device 100 may transmit calibration information to the user terminal device 200. The user terminal device 200 may calculate the user's blood glucose level from the analyte signal based on the calibration information. The calibration information may include parameter values ​​to compensate for time delays due to the diffusion of glucose between the user's interstitial fluid and blood. The parameter values ​​may be calculated through in vivo testing and stored in the analyte monitoring device 100.

[0073] The calibration operation of the analyte signal may be performed by the analyte monitoring device 100. For example, in connected mode, the analyte monitoring device 100 may receive reference data from the user terminal device 200. The reference data may be the user's blood glucose level measured through a blood glucose meter. The analyte monitoring device 100 may calculate the user's blood glucose level from the analyte signal using the blood glucose level received from the user terminal device 200 and pre-stored parameter values.

[0074] FIG. 5 is a diagram illustrating a method for controlling an electronic device according to one embodiment of the present disclosure.

[0075] 5, analyte monitoring device 100 may communicate with multiple user terminal devices 201 and 202. For example, first user terminal device 201 may be a receiver that provides blood glucose information received from analyte monitoring device 100 to a user, and second user terminal device 202 may be a smartphone. However, this is an example, and first user terminal device 201 and second user terminal device 202 may be the same type of device.

[0076] Each of the first user terminal device 201 and the second user terminal device 202 may have authority to wake up the analyte monitoring device 100 (also referred to as wake-up authority for the analyte monitoring device 100). That is, each of the first user terminal device 201 and the second user terminal device 202 may generate a wake-up signal and transmit the generated wake-up signal to the analyte monitoring device 100. For example, the first user terminal device 201 may generate a first wake-up signal. The second user terminal device 202 may generate a second wake-up signal.

[0077] The analyte monitoring device 100 may wake up based on the first received wake-up signal among the wake-up signals transmitted by the user terminal devices 201 and 202, respectively. For example, if a first wake-up signal is received before a second wake-up signal and authentication of the first wake-up signal is complete, the analyte monitoring device 100 may wake up based on the first wake-up signal and establish a communication connection with the user terminal device 201. If the operating mode of the analyte monitoring device 100 is not the sleep mode, the analyte monitoring device 100 may receive the second wake-up signal. In this case, the analyte monitoring device 100 may ignore the second wake-up signal.

[0078] The devices that have wake-up authority of the analyte monitoring device 100 may be predetermined. For example, a receiver may not have wake-up authority, but a smartphone may have wake-up authority. Upon receiving a wake-up signal, the analyte monitoring device 100 may determine whether the device transmitting the wake-up signal has wake-up authority.

[0079] The analyte monitoring device 100 may determine whether the device transmitting the wake-up signal has wake-up authority based on the device identification information (e.g., model number) or type information (e.g., whether the device is a receiver or a smartphone) included in the wake-up signal packet. The analyte monitoring device 100 may compare the device identification information or type information included in the wake-up signal packet with information pre-stored in the analyte monitoring device 100, and determine whether the device transmitting the wake-up signal has wake-up authority depending on whether the identification information or type information matches the pre-stored information. The pre-stored information is information of predetermined devices that have wake-up authority for the analyte monitoring device 100, and may include device identification information or type information.

[0080] For example, if the identification information included in the wake-up signal packet matches the pre-stored identification information, the analyte monitoring device 100 may determine that the device transmitting the wake-up signal has wake-up authority. On the other hand, if the identification information included in the wake-up signal packet does not match the pre-stored identification information, the analyte monitoring device 100 may determine that the device transmitting the wake-up signal does not have wake-up authority.

[0081] Whether a device transmitting a wake-up signal to the analyte monitoring device 100 has wake-up authority for the analyte monitoring device 100 may be determined based on app information included in the wake-up signal packet. Wake-up authority for the analyte monitoring device 100 may be granted only to predetermined apps. For example, a first app may have wake-up authority, while a second app that is a follower app of the first app may not have wake-up authority. When a wake-up signal is received, the analyte monitoring device 100 may determine whether the app information stored in the wake-up signal packet matches pre-stored app information. If the app information matches the pre-stored app information, the analyte monitoring device 100 may determine that the device transmitting the wake-up signal has wake-up authority. If the app information does not match the pre-stored app information, the analyte monitoring device 100 may determine that the device transmitting the wake-up signal does not have wake-up authority.

[0082] Meanwhile, the first user terminal device 201 and the second user terminal device 202 may use different methods to obtain authentication information for a communication connection with the analyte monitoring device 100. For example, the authentication information obtained by the first user terminal device 201 may be obtained by a user directly inputting the authentication information into an input unit included in the first user terminal device 201. The authentication information obtained by the second user terminal device 202 may be obtained by scanning a QR code printed on the analyte monitoring device 100 or the packaging of the analyte monitoring device 100 with a camera.

[0083] FIG. 6 is a block diagram illustrating a configuration of an analyte monitoring system according to one embodiment of the present disclosure.

[0084] Referring to FIG. 6, an analyte monitoring system 1000 may include an analyte monitoring device 100 and a user terminal device 200 .

[0085] Analyte monitoring device 100 may include an analyte sensor 110 and a sensor electronics unit 120. Sensor electronics unit 120 may include a first communication interface 121, a first memory 122, a first processor 123, and a battery 124. For example, analyte monitoring device 100 may be a CGM device.

[0086] The analyte sensor 110 may be configured to sense an analyte signal. The analyte sensor 110 may include at least a portion of a sensor probe inserted into the body. The sensor probe may be formed with a sensing region that reacts with sugars in the body to measure blood glucose in the body.

[0087] The first communication interface 121 may include at least one communication circuit and communicate with various types of external devices. For example, the first communication interface 121 may receive a wake-up signal from the user terminal device 200. In addition, the first communication interface 121 may transmit information about the analyte signal to the user terminal device 200. The first communication interface 121 may include a Bluetooth module, a low-power Bluetooth module, an RF module, and a near field communication (NFC) module.

[0088] The first memory 122 may store an operating system (OS) for controlling the overall operation of the components of the analyte monitoring device 100 and commands or data related to the components of the analyte monitoring device 100. In particular, the first memory 122 may store instructions for setting up a communication connection with the user terminal device 200. The first memory 122 may be implemented as a non-volatile memory (e.g., a hard disk, a solid state drive (SSD), and a flash memory), a volatile memory, etc.

[0089] The first processor 123 may be electrically connected to the first memory 122 and may control the overall function and operation of the analyte monitoring device 100. The first processor 123 may execute instructions stored in the first memory 122 to control the analyte monitoring device 100.

[0090] The first processor 123 may operate in a first mode. The first mode may be a sleep mode (or low-power mode). In this case, the first processor 123 may activate the first communication interface 121 at a first time interval to wait for receipt of a wake-up signal. In the first mode, the first processor 123 may not perform signal processing on the analyte signal. Accordingly, the usage of the battery 124 may be conserved.

[0091] When a wake-up signal is received through the first communication interface 121, the first processor 123 may perform authentication of the wake-up signal. The first processor 123 may demodulate a first portion modulated based on OOK in the packet of the wake-up signal to obtain a first value. If the first value matches a second value pre-stored in the first memory 122, the first processor 123 may determine that the authentication of the wake-up signal is successful.

[0092] If the wake-up signal is successfully authenticated, the first processor 123 may enter an advertising mode. The first processor 123 may establish a communication connection with the user terminal device 200 through the first communication interface 121. The first processor 123 may broadcast using the first communication interface 121 to identify the user terminal device 200.

[0093] Once the user terminal device 200 is identified, the first processor 123 may perform pairing with the user terminal device 200. The first processor 123 may exchange authentication information for pairing with the user terminal device 200 through the first communication interface 121. For the authentication information for pairing, the analyte monitoring device 100 may include identification information about the user terminal device 200. The identification information may be included in the wake-up signal.

[0094] For example, the identification information may include first identification information. The first processor 123 may perform pairing based on whether the first identification information matches second identification information pre-stored in the first memory 122. If the first identification information matches (or is the same as) the second identification information, the first processor 123 may establish a communication channel between the analyte monitoring device 100 and the user terminal device 200. If the first identification information does not match (or is different from) the second identification information, the first processor 123 may not establish a communication channel between the analyte monitoring device 100 and the user terminal device 200.

[0095] Once the communication channel is established, the first processor 123 may control the first communication interface 121 to transmit information about the analyte signal to the user terminal device 200 at a second time interval.

[0096] Analyte monitoring device 100 may include multiple processors. For example, first communication interface 121 may be implemented as a BLE chip. In this case, the BLE chip may include a different CPU than first processor 123. In this disclosure, the operating mode of first processor 123 may refer to the operating mode of analyte monitoring device 100.

[0097] The battery 124 may provide power to the components of the analyte monitoring device 100. The consumption of the battery 124 may vary depending on the operational mode of the analyte monitoring device 100. When the analyte monitoring device 100 is in a sleep mode, the consumption of the battery 124 may be less than the consumption of the battery 124 when the analyte monitoring device 100 is in an advertising mode. When the analyte monitoring device 100 is in an advertising mode, the consumption of the battery 124 may be less than the consumption of the battery 124 when the analyte monitoring device 100 is in a connected mode.

[0098] The user terminal device 200 may include a user input unit 210, a display 220, a camera 230, a second communication interface 240, a second memory 250, and a second processor 260. For example, the user terminal device 200 may be a smartphone.

[0099] The user input unit 210 is configured to receive user commands. The user input unit 210 may receive a user command to wake up the analyte monitoring device 100. The user input unit 210 may receive a user command for a communication connection with the analyte monitoring device 100. The user command to wake up the analyte monitoring device 100 and the user command for a communication connection with the analyte monitoring device 100 do not necessarily have to be separate commands. For example, according to the user command for a communication connection with the analyte monitoring device 100, the analyte monitoring device 100 may be woken up and a communication connection between the analyte monitoring device 100 and the user terminal device 200 may be established.

[0100] The user input unit 210 may include a keypad, a dome switch, a touchpad (hydrostatic / electrostatic), a job wheel, a jog switch, and sensors (e.g., audio sensors, proximity sensors, illuminance sensors, acceleration sensors, gyro sensors, etc.). The user input unit 210 may be implemented in the form of buttons on the outside of the user terminal device 200, and some buttons may be implemented as a touch panel. When a user input (e.g., text input, voice input, change of user device operation, etc.) for defining a rule and executing a rule (e.g., a command) is received, the user input unit 210 may generate input data accordingly.

[0101] Display 220 may output information related to the analyte signal. For example, display 220 may output a user's blood glucose level. In addition, display 220 may output UI elements for receiving user commands. For example, display 220 may output user interface (UI) elements for receiving user commands for a communication connection with analyte monitoring device 100.

[0102] The camera 230 may be used to obtain identification information for authentication between the analyte monitoring device 100 and the user terminal device 200. For example, the user terminal device 200 may use the camera 230 to scan a QR code on the packaging of the analyte monitoring device 100.

[0103] The second communication interface 240 may include at least one communication circuit. The second communication interface 240 may transmit a wake-up signal to the first communication interface 121. The second communication interface 240 may receive information about the analyte signal from the first communication interface 121. The second communication interface 240 may include a Bluetooth module, a low-power Bluetooth module, an RF module, and an NFC module.

[0104] The second memory 250 may store an operating system (OS) for controlling the overall operation of the components of the user terminal device 200 and commands or data related to the components of the user terminal device 200. In particular, the second memory 250 may store instructions for setting up a communication connection with the analyte monitoring device 100. The second memory 250 may be implemented as a non-volatile memory (e.g., a hard disk, an SSD, and a flash memory), a volatile memory, etc.

[0105] The second processor 260 may be electrically connected to the second memory 250 and may control the overall function and operation of the user terminal device 200. The second processor 260 may control the user terminal device 200 by executing instructions stored in the second memory 250.

[0106] The second processor 260 may receive a user command for a communication connection with the analyte monitoring device 100 through the user input unit 210. When the user command is input, the second processor 260 may generate a wake-up signal 420. The second processor 260 may modulate at least a portion of the wake-up signal 420 using the OOK method. The second processor 260 may control the second communication interface 240 to transmit the modulated wake-up signal 420 to the analyte monitoring device 100.

[0107] The second processor 260 may control the display 220 to display information about the analyte signal.
