[0002] This application claims the benefit of U.S. Patent Application Serial No. 18 / 083,484, filed on December 17, 2022, the disclosure of which is incorporated herein by reference. Background Art

[0003] The following information is provided to assist the reader in understanding the technology disclosed below and the environments in which such technology can generally be used. Unless otherwise specifically stated in this document, the terms used herein are not intended to be limited to any particular narrow interpretation. The references set forth herein can facilitate an understanding of the technology or its background. The disclosures of all references cited herein are incorporated by reference.

[0004] A gas detection / detector device (commonly referred to as an "instrument") includes at least one gas sensor, electronic circuitry, and a power source to drive the sensor, interpret its response, and display its response to a user. Such gas detection devices or instruments can include various sensors for detecting gas analytes, including, for example, electrochemical gas sensors and combustible gas sensors. See, for example, U.S. Patent No. 9,784,755, the disclosure of which is incorporated herein by reference. The gas detection device also includes a housing to enclose and protect such components. The gas detection device can be portable or fixed in place. Portable gas detection devices are typically powered by a rechargeable battery system. Portable gas detection devices are carried by authorized users or workers within a company / facility, which may own or lease the portable gas detection devices as assets of the facility. Depending on the size and industry, a company / facility can, for example, have several, dozens, or hundreds or more of such devices shared among a large, dynamic, and temporary workforce.

[0005] There are numerous accessories available in the gas detection market for use with, for example, gas detection devices, and this places a significant responsibility on the end - user to ensure proper use. Accessories including pump probes, sampling lines of various lengths, materials, and use scenarios, and adapters are commonly used in pumped - instrument applications, where the instrument is used as a tool to indicate gas levels in a specific area, and in many cases, the gas is a specific gas or volatile organic compound (VOC).

[0006] Under current practice, the onus is on the user to select the correct accessory device or combination of accessory devices (sometimes referred to as a stack) that forms the accessory device transmission path or accessory device assembly for a gas detection device or instrument. Complicating this issue is that the market is flooded with accessory devices from multiple device manufacturers, from current and previous generations of products, such as sampling lines, probes, and adapters, as such accessory devices are rarely phased out or taken out of service.

Additionally, the accessory device identification and analysis functions herein can be responsible for and facilitate tracking and managing the various gas detection accessory devices of a facility via a software-based management system operatively or communicatively coupled to the gas detection instrument or device.

[0043] Figure 1A , Figure 1B and Figure 2 illustrate an embodiment of a portable instrument, detector device, or device 10 that includes a housing 20 formed by housing sections 22a and 22b to contain one or more sensors 30 that may be disposed within a sensor carriage 32. The carriage 32 also supports a pump system 36 fluidly connected to an inlet 38. Each sensor is operable to detect the presence of an analyte. The sensor 30 is positioned to be connected to the environment to be tested via the inlet 38.

[0044] Device 10 also includes an electronic circuitry 40 that includes a controller or control system to control the operation of the device or instrument 10 and to analyze or interpret the response(s) of the sensor(s) 30. As Figure 2 schematically shown, the control system can include, for example, a processor system 42 (e.g., including one or more microprocessors) operatively coupled to a memory system 44. As Figure 1B shown, the elements of the electronic circuitry can be incorporated into one or more printed circuit boards 41. One or more software algorithms can be stored in the memory system 44 and executable by the processor system 42 to control / operate the device 10, including, for example, data measurement / acquisition, analysis, device accessory identification and analysis as described herein, communication, etc. A user interface system 46 (including, for example, a display 46a (see Figure 1B)), speakers, haptic systems, various input / output systems, etc.) can also be placed in operable or communicative connection with the processor system 42. The communication system 48 is in operable or communicative connection with the processor system 42 to communicate with other devices / systems, either wired and / or wirelessly. The power supply 50 (e.g., a battery system including one or more lithium batteries) provides power to the electronic circuitry 40. The (multiple) gas sensors 30 can be placed, for example, in operable or communicative connection with the electronic circuitry 40 via a Universal Asynchronous Receiver / Transmitter or UART protocol, which can be, for example, part of an integrated circuit (IC) for serial communication through a serial port.

[0045] For example, as described in U.S. Patent Application No. 17,496,420, the disclosure of which is incorporated herein by reference, in multiple embodiments, the gas detection instrument or device 10 can be communicatively connected to a network or grid, e.g., the network or grid that provides software-based assistance (such as Grid Fleet Manager available from Safety io, Inc., Cranberry Township, PA) when managing the gas detection instrument or multiple / a group of gas detection instruments and their accessories. Such a software-based system or grid 500 (see Figure 2 ) can be communicatively connected to or implemented on one or more computers / networks located at a facility or remotely as part of an entire network or system 5, for example. However, as described above, the devices, systems, and methods herein for accessory device identification and analysis can be integrated into a gas detection instrument or device 10 that is not operatively connected or integrated with such a networked system.

[0046] In multiple embodiments, the software-based management system 500 is a cloud-based system that is communicatively connected to one or more computers / networks and / or devices located at a facility. For example, in multiple embodiments, the management system 500 is a cloud-based remote system through which a particular facility can create an account to enable the use of the software-based management system to help the facility integrate and streamline gas detection-related activities in a single source, thereby facilitating information access, instrument / accessory compliance, risk assessment, and worker compliance. The cloud-based system can also facilitate sharing information or data with remote locations (e.g., of manufacturers of gas detection instruments and their accessories) to, for example, further process the data and / or provide enhanced functionality.

[0047] A management system 500, which can include, for example, a computer or multiple interconnected / networked computers, provides a centralized destination for managing / monitoring a group of gas detection instruments and their accessories for a facility. In multiple embodiments, the management system 500 can be accessed, for example, via an account login from a facility computer, a mobile device, etc. For example, it can provide real-time notifications, instrument configuration, group management, and related context reports via a system / grid. The management system 500 can, for example, execute a web-based application to send data to system 5 and receive data from system 5.

[0048] Figure 2 An embodiment of system 5 of the present disclosure for an entity or facility is shown, the system including a (plurality of) portable gas detection device instruments 10 and their associated equipment or accessory devices. In the illustrated embodiment, system 5 includes a system 80 for instrument charging and testing that can include, for example, one or more single-unit and / or multi-unit chargers, a calibration station, and a cylinder holder for operably connecting to a gas cylinder. The interaction of the (plurality of) instruments 10 with system 80 to effect assignment to and deassignment from a particular user is described, for example, in U.S. Patent Application No. 17,496,420. Various wired and / or wireless communication protocols, as shown in representative embodiments such as Figure 2 can be used in system 5 to transfer data between facility devices / systems and between facility devices / systems and a supervisory or management system 500. The supervisory or management system 500 includes one or more processor systems programmed with one or more algorithms stored in a memory system, for example, as described herein and in U.S. Patent Application No. 17,496,420.

[0049] In the illustrated embodiment, the portable gas detection device 10 includes an accessory device identification system communicatively coupled to a control system, which may include, for example, one or more communication devices operable to transfer data / information or configured to transfer data / information. Such communication devices may be integrated into or operatively / communicatively coupled to the communication system 48 and / or the electronic circuitry 40, for example. The one or more communication devices communicate with corresponding or cooperative communication devices of the (multiple) gas detection accessory devices 200 to be used with the device 10. In multiple embodiments, the proximity of the communication instrument or device 10 to the corresponding communication device 210 of the gas detection accessory device 200 may initiate the transfer / transmission of data / information without user intervention, other than taking some action to effect the proximity. The (multiple) communication devices of the device 10 may communicate with the corresponding communication device 210 or identifier of the gas detection accessory 200 by wired means (e.g., by contact of one or more conductive contact elements) or wireless means (e.g., via electromagnetic waves such as radio waves, via Hall effect switches, or via optical reading methods such as barcode readers). As described above, in the case of using an accessory device combination in a component attached to the inlet 38, in multiple embodiments, each accessory device 200 in the combination may be identified sequentially. For example, each accessory device 200 may include a separate RFID tag (or other proximity device) and sequentially approach the device 10 to identify all of the accessory devices 200 in the combination. In other embodiments, a combination or stack of accessory items to be used in a component attached to the inlet 38 may be provided, for example, in the form of a kit, and a single RFID tag (or other proximity device) may be associated with the combination to send or provide data including identification data for the combination or stack of components.

[0050] The apparatus 10 may also or alternatively monitor one or more operating variables or parameters (e.g., via one or more sensors), such as pump motor back electromotive force (back EMF), pressure (e.g., measured via a pressure transducer), and / or pulse width modulation parameters, to identify the attached accessory device 200 or combination of accessory devices based on data of such operating variables or parameters stored. Additionally, time and environmental conditions such as temperature and relative humidity may be measured and tracked for identification and / or analysis. The environmental conditions may, for example, affect the measured operating variables or parameters, such as pump motor back EMF, pressure, and / or pulse width modulation parameters. For example, the pump motor back EMF and / or pressure may be measured at startup to detect a change in the motor pull-in torque, which is caused by the characteristic of one or more accessory devices creating a pressure drop across one or more accessory devices (e.g., sampling lines, etc.) when they are attached to the apparatus 10. For example, the detection of one or more operating parameters for accessory device identification may be used to reduce the user interaction steps in the identification process (compared to, for example, using a proximity-based communication system). Generally, once all components of the accessory device combination are attached to the apparatus 10, the back EMF, pressure, and / or PWM parameters are measured and matched with stored values or value ranges to identify the accessory device combination. However, one or more such variables or parameters may also be measured when each accessory device 200 is connected sequentially. Data of operating variables or parameters such as back EMF, pressure, and / or pulse width modulation parameters may be stored in a database herein for individual accessory devices 200 and / or combinations of accessory devices to identify them (as described above, individually or jointly). Such data may be stored, for example, as a function of environmental conditions and / or other conditions that may affect its measurement (e.g., as an algorithm or as a look-up table).

[0051] In multiple embodiments, for example, in a case where a user cannot use a proximity-based (or other) method to identify the accessory device 200 configured to be attached to the apparatus 10, detecting variables or parameters such as back EMF, pressure, and / or PWM parameters may be used as a backup. For example, if an increase in back EMF and / or pressure is detected, the apparatus 10 may prompt the user to ask if the accessory device 200 has been connected, and if not, determine if there is an error / fault in the system. If the accessory device 200 has been attached to the apparatus 10, the user may be prompted to perform an identification procedure as described herein (e.g., a proximity-based procedure).

[0052] Additionally, operating variables or parameters such as back electromotive force, pressure, and / or pulse width modulation parameters can be used to check whether the identified attachment device 200 or a combination thereof is correctly attached and / or operating. For example, a leak in the attachment device delivery path or the attachment device path may result in a back electromotive force or pressure that is higher than the back electromotive force or pressure stored in the memory for the identified attachment device(s) 200. A blockage or occlusion in the attachment delivery line (e.g., a blocked filter) may result in a back electromotive force or pressure that is lower than the back electromotive force or pressure stored in the memory for the identified attachment device(s) 200. Data for determining the correct attachment and / or operation of the attachment device can be stored in the database herein and may overlap partially or completely with the stored data used when identifying device attachments via device operating parameters.

[0053] In the case where the attachment device 200 or a combination of attachment devices 200 is not recognized by the attachment device recognition system herein due to the absence of associated identification information in the database, the device 10 can prompt or warn the user. The user can also be provided with the option to manually enter information about the unrecognized attachment device 200 (e.g., in the case of a sampling line, the manufacturer, length, diameter, etc. of the sampling line). Data for the new attachment device 200 or a combination thereof can be uploaded to the device 10 via communication from, for example, the system 5 (e.g., via the management system 500; e.g., via a software update). Similarly, for example, the data for the attachment device(s) 200 or a combination thereof present in the database can be updated via communication through the system 5 as described for the new attachment device(s) 200 or a combination thereof.

[0054] Examples of wireless data communication devices suitable for use herein for transferring data in close proximity include, but are not limited to, radio frequency identification (RFID) devices and near field communication (NFC) devices. In the plurality of representative embodiments discussed herein, the communication device of the instrument 10 includes an RFID device, reader, or chip 60 that is operatively or communicatively connected to the electronic circuitry 40. As is known in the art, RFID systems utilize electromagnetic energy / fields to wirelessly communicate with RFID tags associated with an object. RFID tags include a microchip or integrated circuit for storing and processing information. The integrated circuit further modulates and demodulates radio frequency or RF signals. RFID tags also include an antenna for receiving and transmitting signals over a relatively short distance. The data / information of the tag is stored in non-volatile memory. Fixed or programmable logic is provided for processing transmission and sensor data.

[0055] Also as Figure 2As shown in an embodiment of system 5, information associated with individual user data can be automatically transmitted substantially via, for example, card 300 (or other objects or items carried by the user, including those worn by the user), which includes a communication device such as RFID device / tag 310. In this regard, when card 300 is placed adjacent to RFID reader 60, individual user data (associated with the user, such as identity, entity affiliation, etc.) can be transmitted to the RFID device / reader 60 of device 10. In multiple embodiments, the data transmitted from the tag includes the UUID (Universal Unique Identifier) of RFID device / tag 310 or other unique identification information. The UUID or other unique identification information of RFID tag 310 is associated with the information of the individual user in the database of management system 500. In this regard, when the user / worker removes device 10 from the bay of the charger of system 80, device 10 reads the user's information (e.g., reads from card 300 when adjacent to device 10), and device 10 is designated as being assigned to the user. Device 10 can remain assigned to the user until the instrument 10 is placed in one of the bays of the verified chargers of system 80 and de-assignment occurs.

[0056] In addition to transmitting information from card 300 to device 10, information can also be transmitted from the user's card 300 and / or another device of system 5 to the user's personal communication device 400, as Figure 2 shown. For example, personal communication device 400 can be a device that supports Near Field Communication NFC / RFID, schematically represented by element 410 in Figure 2 . In addition, personal communication device 400 can receive data from device 10 via RFID communication from RFID tag 60' of device 10 or other communication instruments. Personal communication device 400 (e.g., a smart phone) can be used, for example, to manage RFID tags and associate data with such tags in management system 500. In this regard, an application or app can be downloaded (e.g., from management system 500), via which personal communication device 400 can be used, for example, to set up / program RFID tags or other communication devices to, for example, associate the personal / identity information or data of the associated user with the UUID of RFID tag 310 or other communication devices of card 300. The mobile app on personal communication device 400 can be used, for example, to download the employee roster from management system 500. Placing personal communication device 400 near card 300 can be used, for example, to achieve pairing in the cloud.

[0057] As elaborated above, in order to use the portable gas detection instrument of the gas monitoring system of an entity (e.g., a company or a facility), multiple accessory devices are desirable or necessary. For example, as Figures 3A to 4BAs shown, portable instruments such as instrument 10 are often used in combination with various accessory devices, including sampling lines and probes, through which an environmental sample is pumped via a pump system 36 fluidly connected to an inlet 38 through the sampling lines and probes to a sensor (see Figure 1B ). In conjunction with Figures 3A to 4B , Tables 1 through 8 below provide some insights into the various sampling line options available from a single vendor (MSA Safety Incorporated, Cranberry Township, Pennsylvania).

[0074] Figure 5A representative example of a workflow diagram is shown for performing gas sensing in a confined space prior to entry using a portable gas sensing instrument or device (such as device 10) and using a sampling line and probe (and, if needed, one or more adapters as may be appropriate) connected thereto. As noted above, the responsibility for selecting the correct accessory device / accessory device combination (e.g., sampling line and probe) for the sensor configuration of device 10 currently falls on the user. When selecting an appropriate instrument or device 10 that includes appropriate sensors and alarm settings, selecting the sampling line, probe, and possible adapters requires selecting accessory device characteristics including, but not limited to, length, diameter, conductive versus non-conductive materials, reactive versus non-reactive materials, probe length, and the appropriate adapter(s). The selection is complicated due to the many alternative choices of accessory devices. As discussed above, Tables 1 through 8 provide representative examples of accessory device options available from a single manufacturer. Also as noted above, sampling lines and probes for multiple generations of products, as well as various adapters for use therewith, are available in the market from multiple device manufacturers. As Figure 6A shown herein, the devices, systems, and methods herein provide multiple opportunities for improvement after accessory identification, including but not limited to sensing and remedying improper installation, notifying of incorrect accessory device(s), reducing the likelihood of human error when attaching (or operating) one or more accessory devices 200 of an assembly, recommending or controlling the operating parameters of device 10 based on the identified accessory device, and so forth.

[0075] Figure 6BAn embodiment of a workflow diagram for accessory identification and corresponding analysis / processing in system 5 using the apparatus, system, and method herein is shown. After starting apparatus 10, a user may perform, for example, a pump function check. In multiple embodiments, before attaching (multiple) accessory devices 200, each accessory device 200 is brought close to the RFID device / reader 60 of the instrument 10, similar to the process described above for individual user data from card 300. After placing (multiple) accessory devices 100 adjacent to the RFID reader 60, data associated with one or more accessory devices 200 may be transmitted to the RFID device / reader 60 of apparatus 10. In multiple embodiments, data transmitted from the RFID tag 210 includes the UUID of the RFID device / tag 210 and / or other unique identification data / information. The UUID or other unique identification information of the RFID tag 210 is associated with and matchable to the reference identification information of (multiple) accessory devices 200 in the database of the accessory device identification system herein. The database or database system may be one or more of a database stored in the memory 44 of the instrument / device 10, stored on the management system 500, stored in a facility computer, or distributed among various components of system 5. In the first case, the identity of (multiple) accessory devices 200 is determined based on data stored in one or more databases. Characterization data associated with (multiple) identified accessory devices 200 is also stored in (multiple) databases. Such data may include, for example, data provided in any of Tables 1 to 8, selection criteria as set forth in Figure 5 as elaborated, and other data for analysis, such as compatibility with apparatus 10, compatibility with other accessory devices or combinations / stacks of accessory devices, parameters for determining or verifying identification or for determining proper installation, parameters for using an accessory device or combination of accessory devices, apparatus operation parameters, recommendations for optimal apparatus operation parameters for a given accessory device or combination of accessory devices, and so on. Such stored characterization data may depend on or include usage conditions (including, for example, location / mode of use, environmental conditions, user, etc.). Table 9 below elaborates representative data for accessory device component identification and representative data for characterizing / analyzing two representative accessory device components (where each such component includes only a sampling line and no sampling probe or adapter). Component A includes a sampling tube with a length of 10 feet and a diameter of 1 / 8 inch. Component B includes a sampling tube with a length of 50 feet and a diameter of 1 / 16 inch. Additional characterization data may be provided as described herein and according to the required analysis of the use of various accessory device components. If needed, the flow rate may be measured or calculated as a function of back electromotive force and pressure.

[0076] Table 9

[0077]

[0078] Automated or semi-automated identification of an attachment device assembly including one or more attachments 200 and analysis / matching of such attachment devices 200 and their combinations or stacks can be used to significantly reduce the burden on a user in selecting an attachment device 200 or a combination / stack of attachment devices 200 for use with a device 10. With little or no input from the user, the devices, systems, and methods herein can identify the attachment device(s) 200 to be attached to the device 10 and analyze the information associated with such attachments 200 / compare that information to, for example, the sensor configuration of the device 10. In the illustrated embodiment, the device 10 checks the compatibility of the identified attachment device(s) 10 with the sensor configuration of the instrument or device 10, the compatibility of the attachment devices 200 with each other, the compatibility with the location, etc. The location can be determined, for example, by GPS data, a positioning system at the facility, and / or other methods known in the art of positioning. Alerts and / or flags can be provided to the user via, for example, another component of the device 10 and / or the system 5 to prompt the user of an unsafe or inappropriate use scenario. Additionally, a determination (and an alert provided) can be made if a particular user may not be sufficiently qualified / trained for a particular use associated with, for example, the identified attachment device 200 / attachment device combination and / or a particular location of use. The device 10 can, either alone or in conjunction with analysis / processing from one or more other components of the system 5, further provide the user with increased confidence in the appropriate settings via a confirmation prompt and / or instructions to assist in creating an appropriate or optimal setting.

[0079] In multiple embodiments, lock settings can be provided in software stored in the memory system 44 of the device 10 (and / or elsewhere on an associated network or grid). If such lock settings are enabled, the device 10 can be set to not enter the normal operation mode when a trigger state is detected, e.g., when an incompatible attachment device or attachment device combination is placed in connection with the device 10, when the user assigned to the device is not sufficiently qualified / trained as described above, and / or when improper attachment or function of the attachment device(s) is detected based on pre-determined and stored criteria. In multiple embodiments, if the lock settings are enabled and a trigger state is detected (e.g., an incompatible attachment device 200 or attachment device combination is identified), the device 10 will enter a locked state. Alternatively or additionally, an alert or warning can be provided to the user. In multiple embodiments, once the trigger state is removed or overridden, the device 10 can return to an unlocked or operating state.

[0080] The identification of the accessory device 200 can provide additional benefits in terms of the operational efficiency and safety of the device 20. For example, if the sensor 30 of the device 10 or another sensor / device of the system 5 (e.g., a sensor of a fixture or another portable device) detects one or more gases in a relevant location that are chemically incompatible with the identified accessory device 100 or incompatible with relevant safety regulations or protocols (which may vary depending on the location), a prompt or warning may be provided to change one or more of the accessory devices 200.

[0081] The identification of the accessory device 200 can be used to control or change the function of the device 10 (e.g., the way a menu is presented). The identification of the accessory device 200 by the device 10 and the determination of its compatibility and proper installation can, for example, cause the device 10 to initiate or enter a sampling mode of the device 10 or prompt the user to enter the sampling mode. For example, in the case of multiple currently available devices 10, entering the sampling mode may require navigating through multiple menus / sub-menus. Identifying the (multiple) accessory devices 200 attached to the device 10 (and optionally, in some embodiments, determining their correct attachment) can, for example, automatically display menu options for the user to enter the sampling mode, thereby simplifying and streamlining the operation of the device 10.

[0082] As described above, the identification of the (multiple) accessory devices 200 can be used to achieve efficiency gains in sampling via stored knowledge or characterization data based on, for example, pipeline length, diameter, material properties, probes, etc. For example, in current practice, the user has to determine how much time to wait before a reading should be taken via the device 10. In this regard, sufficient time must elapse before the sample pumped from the environment to be tested reaches the sensor 30. Rules of thumb can be used, such as a defined delay period (e.g., 2 seconds or 3 seconds) per foot or per meter of sampling pipeline length. In this regard, the amount of time for a sample from the environment being tested to reach the sensor 30 of the device 10 increases as the length of the sampling pipeline accessory (e.g., Figure 3A and Figure 3B the sampling pipelines 200a and 200b shown in Figure 3BThe probe 200c) can generate different sample flow characteristics. When identifying the attachment device 200, the device 10 can, for example, calculate the sampling time based on the characteristics of the identified attachment device 200 that are stored. Data on environmental conditions that affect flow or data sent from another device of the system 5 to the device 10 can also be used when determining the sampling time. The environmental conditions are, for example, humidity, temperature, pressure, and / or altitude from various sensors that can be incorporated into the device 10. Thus, in addition to improving or optimizing the attachment settings, the operation of the device 10 can also be improved or optimized based on the identification of the attachment device(s) 200.

[0083] The user typically ends sampling after following the standard operating procedure (SOP) for a specific location / site and recording the results. In the case of entering a restricted site, sampling can be performed, for example, at multiple depths or distances. Sampling can also be repeated. For example, the data recorded can include the start time and the level measured at the start of the monitoring, the level readings at each depth / distance, continuous air monitoring at given time increments, and the time of entry into the restricted space after approval.

[0084] An additional benefit of the attachment device identification herein is that asset management of the attachment devices can be easily performed via a software-based management system or grid 500. The sample data can be automatically uploaded to the management system or grid 500, for example. After the attachment device 200 is identified as being associated with or attached to the device 10, the management system or grid 500 enables tracking of which attachment device(s) 200 has been (or have been) associated with each instrument (and by which user(s)) during a specific time period, how many attachments have been used, the usage frequency of each attachment and / or attachment combination, etc. The attachment device management provided by the management system or grid 500 can thus help the facility understand and track usage and requirements. In addition, misuse can be identified if an incorrect attachment device is being used at a specific sampling location. For example, a specific location can be designated as requiring a specific attachment setting, and if an incorrect setting is being used as described above, the GPS or other device location during sampling can trigger an alarm. The need for further training for all or one or more specific users can be identified.

[0085] Tracking the use of the device 10 and the attachment device 100 used in conjunction with it, as well as the sample data (including exposure to various gases), can be used, for example, to diagnose problems with the device 10, schedule calibration or maintenance procedures, or estimate the device life. Such data can also be used in optimization algorithms to improve the method, the device 10, the attachment device 200, and / or their combination.

Of course, various modifications, additions, and alternative designs will become apparent to those skilled in the art without departing from the scope herein, which is indicated by the following claims rather than the foregoing description.
