[0002] This application claims the benefit of U.S. non-provisional patent application serial number 17 / 496,420, filed October 7, 2021, the disclosure of which is incorporated herein by reference. Background Technology

[0003] The following information is provided to help readers understand the techniques disclosed below and the environments in which such techniques are typically used. Unless otherwise expressly stated in this document, the terminology used herein is not intended to be limited to any particular narrow interpretation. The references presented herein may help in understanding the techniques or their context. All disclosures in all references cited herein are incorporated by way of citation.

[0004] Gas detection equipment (generally referred to as an "instrument") includes at least one gas sensor, an electronic circuitry system, and a power source for driving the sensor, interpreting its response, and displaying the response to a user. Such gas detection instruments may include a variety of sensors for detecting gaseous 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. Gas detection instruments further include a housing to enclose and protect such components. Gas detection instruments can be portable or stationary. Portable gas detection instruments are typically powered by a rechargeable battery system. Portable gas detection instruments are carried by authorized users or workers within a company / facility that may own or lease portable gas detection instruments as facility assets. Depending on size and industry, a company / facility may, for example, have several, dozens, hundreds, or more of such instruments shared by a large, dynamic, and temporary workforce.

[0005] The tracking, maintenance, and control of portable gas detectors and their accessories can become cumbersome and complex, especially in large facilities. As part of the tracking of portable gas detectors, authorized users complete procedures to allocate the detectors at the start of their shift. Similarly, at the end of their shift, authorized users return the detectors and complete return procedures. In current practice, such procedures are typically documented on paper or manually entered into a dedicated software program separate from other tracking, maintenance, and / or control procedures and processes. Summary of the Invention

[0006] On one hand, the management system includes a processor system and a communication system operatively connected to the processor system. The communication system is configured to communicatively connect to the gas monitoring system of the entity. The gas monitoring system further includes one or more portable gas detection instruments. Each portable gas detection instrument includes one or more gas sensors and a rechargeable battery system. The gas monitoring system further includes one or more chargers configured to charge the rechargeable battery system of each portable gas detection instrument. The management system further includes a memory system operatively connected to the processor system. The memory system includes algorithms executable by the processor system stored therein and a database associated with the algorithms stored therein. The database includes data identifying each charger as an asset of the entity and each portable gas detection instrument as an asset of the entity.

[0007] When one of the portable gas detectors docks with one of the chargers, communication is initiated between the docked portable gas detector and the charger, and data regarding the docking and the identity of the charger is electronically transmitted to the management system via the gas monitoring system. The management system's processor is configured to execute an algorithm to confirm that the charger is identified as an entity's asset when data regarding the docking and the charger's identity is transmitted from the gas monitoring system to the management system, and if the charger is identified as an entity's asset, to deassign the portable gas detector from one of the multiple users previously assigned to it.

[0008] In several embodiments, the gas monitoring system further includes a plurality of identification communication devices. Each of the plurality of identification communication devices is configured to be associated with and carried by one of the plurality of users. The database further includes data identifying one of the plurality of users associated with each of the plurality of identification communication devices. When one of the plurality of users removes a portable gas detector from one of the chargers and positions one of the plurality of identification communication devices associated with that user in proximity to the portable gas detector, communication is initiated between the portable gas detector and the plurality of identification communication devices associated with that user, and data regarding the identity of the portable gas detector and the identity of one of the plurality of users is electronically transmitted through the gas monitoring system to the management system. The processor system of the management system is configured to execute an algorithm to assign the gas detector to one of the plurality of users when data regarding the identity of the portable gas detector and the identity of one of the plurality of users is transmitted from the gas monitoring system to the management system.

[0009] In several embodiments, each of the portable gas detectors includes an electronic circuitry operatively connected to a rechargeable battery system, a communication system operatively connected to the electronic circuitry system, and a communication device operatively connected to the electronic circuitry system. For example, each charger may include one or more charging slots to charge the rechargeable battery system of the portable gas detector. Each charger may further include a separate cooperative communication device associated with each of the one or more charging slots, the cooperative communication device being unique to the charger and configured to transmit information to the communication device of the portable gas detector when the portable gas detector is docked in one of the associated one or more charging slots.

[0010] For example, data can be transmitted from the gas monitoring system to the management system via the communication system of the portable gas detector.

The management system includes a processor system, a communication system operatively connected to the processor system and configured to communicate with the gas monitoring system of the entity, and a memory system operatively connected to the processor system. The memory system includes algorithms executable by the processor system stored therein and a database associated with the algorithms stored therein. The database includes data identifying each charger as an asset of the entity and each portable gas detection instrument as an asset of the entity. When one of the portable gas detection instruments docks with one of the chargers, communication between the docked portable gas detection instrument and the charger is initiated. The method further includes transmitting data regarding the docking and the identity of the charger from the gas monitoring system to the management system. Furthermore, when data regarding docking and the identity of one of the chargers is transmitted from the gas monitoring system to the management system, the processor system executes an algorithm to confirm that one of the chargers is identified as an entity's asset, and if one of the chargers is identified as an entity's asset, the gas detector is deassigned from one of the multiple users who previously had one of the portable gas detectors.

[0013] For example, the gas monitoring system may further include multiple identification communication devices, each of which is configured to be associated with and carried by one of a plurality of users. The database may further include data identifying one of the plurality of users associated with each identification communication device, wherein communication is initiated between one of the portable gas detectors and one of the multiple identification communication devices associated with one of the plurality of users when one of the plurality of users removes the portable gas detector from one of the chargers and positions one of the multiple identification communication devices associated with one of the plurality of users in proximity to the portable gas detector, and data regarding the identity of the portable gas detector and the identity of one of the plurality of users is electronically transmitted by the gas monitoring system to the management system. The processor system of the management system may, for example, be configured to execute an algorithm to assign the one gas detector to one of the plurality of users when data regarding the identity of the portable gas detector and the identity of one of the plurality of users is transmitted from the gas monitoring system to the management system.

[0014] In several embodiments, each of the portable gas detectors includes an electronic circuitry system operatively connected to a rechargeable battery system, a communication system operatively connected to the electronic circuitry system, and a communication device operatively connected to the electronic circuitry system. For example, each charger may include one or more charging slots to charge the rechargeable battery system of the portable gas detector. For example, each charger may include a separate cooperative communication device associated with each of the one or more charging slots, the cooperative communication device being unique to the charger and configured to transmit information to the communication device of the portable gas detector when the portable gas detector is docked in one of the associated one or more charging slots.

[0015] In several embodiments, data is transmitted from the gas monitoring system to the management system via the communication system of the portable gas detector. The communication system of each portable gas detector may communicate with the management system, for example, via a cellular connection. In several embodiments, the communication device of each portable gas detector includes an RFID reader, the cooperating communication device of each charger includes an RFID tag, and each of the plurality of identification communication devices includes an RFID tag.

[0016] Data about the use of one of the portable gas detectors, which is assigned to one of the multiple users, can be transmitted to the management system, for example, associated with one of the multiple users, until the management system deassigns the portable gas detector from one of the multiple users.

[0017] On the other hand, a system includes a physical gas monitoring system and a management system. The physical gas monitoring system includes one or more portable gas detection instruments, each of which includes one or more gas sensors and a rechargeable battery system, and one or more chargers configured to charge the rechargeable battery system of each portable gas detection instrument. The management system includes a processor system, a communication system configured to communicatively connect with the physical gas monitoring system, and a memory system operatively connected to the processor system. The memory system includes algorithms executable by the processor system stored therein and a database associated with the algorithms stored therein. The database includes data identifying each charger as an asset of the physical entity and each portable gas detection instrument as an asset of the physical entity. When one of the portable gas detection instruments docks with one of the chargers, communication between the docked portable gas detection instrument and the charger is initiated, and the gas monitoring system electronically transmits data regarding the docking and the identity of the charger to the management system. The processor system of the management system can be configured to execute an algorithm to confirm that one of the chargers is identified as an entity's asset when data about docking and the identity of one of the chargers is transmitted from the gas monitoring system to the management system, and if one of the chargers is identified as an entity's asset, to deassign the gas detector from one of the multiple users who previously assigned one of the portable gas detectors.

[0018] In several embodiments, the gas monitoring system further includes a plurality of identification communication devices, each of which is configured to be associated with and carried by one of a plurality of users. The database may, for example, further include data identifying one of the plurality of users associated with each of the plurality of identification communication devices. When one of the plurality of users removes the portable gas detector from one of the chargers, one of the plurality of identification communication devices associated with that user is positioned close to the portable gas detector, initiating communication between the portable gas detector and the plurality of identification communication devices associated with that user. Furthermore, data regarding the identity of the portable gas detector and the identity of one of the plurality of users is electronically transmitted from the gas monitoring system to the management system. The processor system of the management system is configured to execute an algorithm to assign the gas detector to one of the plurality of users when data regarding the identity of the portable gas detector and the identity of one of the plurality of users is transmitted from the gas monitoring system to the management system.

Each charger may include a separate cooperative communication device associated with each of the one or more charging slots, the cooperative communication device being unique to the charger and configured to transmit information to the communication device of the portable gas detector when the portable gas detector is docked in one of the associated one or more charging slots.

[0020] In several embodiments, data is transmitted from the gas monitoring system to the management system via the communication system of the portable gas detectors. The communication system of each portable gas detector may communicate with the management system, for example, via a cellular connection. In several embodiments, the communication device of each portable gas detector includes an RFID reader, the cooperating communication device of each charger includes an RFID tag, and each of the plurality of identification communication devices includes an RFID tag.

[0034] As used herein, the term "processor" includes, but is not limited to, any combination of virtually any number of processor systems or individual processors, such as microprocessors, microcontrollers, central processing units (CPUs), and digital signal processors (DSPs). A processor may be associated with a variety of other circuitry that supports its operation, such as random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), clocks, decoders, memory controllers, or interrupt controllers.

[0039] As used herein, the term “database” refers to an organized collection of structured information or data that is typically stored electronically in a storage system of a computer system.

[0040] The use and maintenance of portable gas detectors for gas monitoring systems in physical entities (such as companies or facilities) require numerous accessories. For example, a charger or charging unit is needed to charge the portable gas detector's battery system. The charger for a portable gas detector may, for example, include one or more slots for charging a single or multiple instruments. Portable gas detectors are typically charged at the end of each shift / use.

[0041] Furthermore, gas detection instruments require regular calibration for continuous operation. Out of an abundance of caution, all gas detection instruments must undergo periodic functional testing. For example, it is common practice to periodically perform "crash tests" or functional checks on portable gas detection instruments. The purpose of this test is to ensure the functionality of the entire gas detection instrument. Regular crash tests or functional checks may extend the time interval between full calibrations. A crash test typically involves: a) applying a target gas (usually a gas with a known concentration of the gas the instrument is to detect or its simulant); b) collecting and interpreting the sensor response; and c) indicating the functional status of the system (i.e., whether the instrument is functioning correctly) to the end user. This crash test is performed periodically, typically daily. A crash test performs all necessary functions of all parts of the gas detection device in the same way required to detect hazardous gas alarm levels. In this respect, a crash test ensures a valid gas delivery from outside the instrument through any transmission path (including, for example, any protective and / or diffusion membranes) to contact the active sensor components. A crash test also ensures that the detection aspect of the sensor itself is functioning correctly and that the sensor provides the correct response function or signal. A crash test further ensures that the sensor is correctly connected to its associated power supply and electronic circuitry and that the sensor signal is correctly interpreted. In addition, the collision check ensures that the indicators or user interface of the gas detection instrument (e.g., displays and / or notification functions) are functioning as expected.

[0042] Recently, electronic and other tests have been developed to test instrument sensors, electronics, and / or transmission paths without requiring the application of calibration or test gases to gas detection instruments. See, for example, U.S. Patent Nos. 9,410,940, 9,562,873, 9,528,957, 9,784,755, 10,234,417, 10,578,573, 10,627,379, 10,788,457, 10,788,458, 10,908,111, 10,948,469, and 10,983,103, and U.S. Patent Application Publications Nos. 2020 / 0103387, 2020 / 0363306, 2020 / 0393405, and 2021 / 0181135, the disclosures of which are incorporated herein by reference. For example, such testing can extend the time required between crash testing and / or full calibration.

[0043] Figure 1 and Figure 3 An embodiment of a portable instrument or device 10 is shown, comprising: a housing 20 formed by housing portions 22a and 22b to enclose one or more sensors 30, each sensor 30 operable to detect the presence of an analyte; and an electronic circuitry system 40 including a controller or control system to control the operation of the sensors 10 and to analyze or interpret the responses of the sensors 30. Figure 3 As schematically illustrated, the control system may, for example, include a processor system 42 (e.g., including one or more microprocessors) operatively connected to the memory system 44. Figure 1 As shown, the components of the electronic circuit system can be incorporated into one or more printed circuit boards 41a and 41b. One or more software algorithms can be stored in the memory system 44, which can be executed by the processor system 42 to control / operate the instrument 10, including, for example, data measurement / acquisition, analysis, communication, etc. The user interface system 46 includes, for example, a display 46a (see...). Figure 1 and Figure 3 The electronic circuitry system 40 may also be positioned to be operatively or communicatively connected to the processor system 42. The communication system 48, operatively or communicatively connected to the processor system 42, is used for wired and / or wireless communication with other devices / systems. The power supply 50 (e.g., a battery system comprising one or more lithium batteries) powers the electronic circuitry system 40. The gas sensor 30 may, for example, be positioned to be operatively or communicatively connected to the electronic circuitry system 40 via a Universal Asynchronous Receiver / Transmitter (UART) protocol, which may be, for example, part of an integrated circuit (IC) for serial communication on a serial port.

[0044] Figures 2A to 2D An embodiment of a multi-unit charger 200 is shown, via which the power supply / battery 50 of one or more instruments 10 is charged. For example... Figure 3 As schematically illustrated, the gas detection system 500 of this document (which includes one or more instruments 10 and its single-unit and / or multi-unit charger 200) may, for example, further include a calibration stand 300, a gas cylinder holder 400, and one or more gas sensing instruments 10. The calibration stand 300 and the gas cylinder holder 400 are described, for example, in U.S. Patent No. 7,530,255.

[0045] In several embodiments described herein, a software-based system or grid is provided to help manage a fleet of gas detection instruments 10 and their accessories. Such a software-based system or grid can be implemented, for example, on one or more computers located at a facility or remotely. In several embodiments, the software-based management system or grid is a cloud-based system. For example, the management system described herein is a cloud-based system through which a specific facility can create accounts to use the software-based management system to assist the facility in consolidating and streamlining gas detection-related activities from a single source, thereby facilitating information access, instrument / accessory compliance, risk assessment, and worker compliance. The cloud-based system can also facilitate the sharing of information or data with remote locations (e.g., the location of the manufacturer of the gas detection instruments and their accessories) to, for example, further process the data and / or provide enhanced functionality.

[0046] An area requiring further development is the tracking, maintenance, and control of portable gas detection instruments and their accessories in facilities, particularly the return / deallocation and removal / allocation of portable gas detection instruments during use. As mentioned above, under current procedures, facilities or companies typically use paper records to allocate specific instruments used with users / workers at the start of a shift and to return / deallocate the instrument at the end of the shift. In many more mature implementations, information is manually entered into a dedicated software system. In current practice, data generated by the instrument during its use is generally not associated with a specific user or worker, whether real-time or historical. In several embodiments, the devices, systems, and methods described herein automate the allocation and / or return / deallocation process. Furthermore, the devices, systems, and methods described herein can be readily used to automatically allocate or associate devices / instruments (and data points associated with the use of such devices / instruments) with specific users / workers during one or more time periods (determined by the automated allocation and return / deallocation methods described herein).

[0047] In several embodiments described herein, a software-based management system is configured to communicate with the entity's gas monitoring system. Electronic communication between the gas instrument and charger of such portable gas detectors of a particular entity is used to automate the dispensing / de-dispensing process via the management system of each portable gas detector of the entity.

[0048] Figure 3 An embodiment of the gas monitoring system 500 described herein, including a portable gas detector 10 and its accessories, is shown. In the illustrated embodiment, system 500 includes an accessory system 80, which includes one or more single-unit and / or multi-unit chargers 200, a calibration stand 300, and a gas cylinder holder 400 operatively connected to a gas cylinder. Figure 3 Various wired and / or wireless communication protocols shown can be used in system 500 to transfer data between devices and to a monitoring or management system 800, which includes one or more processor systems programmed, for example, with one or more algorithms stored in a memory system as described herein.

[0049] In the illustrated embodiment, the portable gas detector 10 includes one or more communication devices operable or configured to transmit data / information to or from an associated memory. Such communication devices may, for example, be integrated into or operatively connected to / communicate with communication system 48 and / or electronic circuit system 40. When the instrument 10 is docked in one of its charging slots 210, the one or more communication devices communicate with a corresponding communication device in the multi-unit charger 200. In this respect, proximity of the communication device of the instrument 10 and the corresponding communication device of the charging slot 210 can initiate communication / transmission of information without user intervention other than taking some action to achieve docking. The communication device of the instrument 10 can communicate with the corresponding communication device of the multi-unit charger 200 via a wired means (e.g., contact via one or more conductive contact elements) or a wireless means (e.g., via electromagnetic waves, such as radio waves). Examples of wireless communication devices suitable for this document include, but are not limited to, radio frequency identification (RFID) devices and near field communication (NFC) devices. In several embodiments, the communication device of instrument 10 includes an RFID device, reader, or chip 60 that is operatively or communicatively connected to the electronic circuit system 40. As is known in the art and as... Figure 4 As illustrated schematically, an RFID system utilizes electromagnetic energy / fields to wirelessly communicate with RFID tags associated with objects. The RFID tag includes a microchip or integrated circuit for storing and processing information. The integrated circuit further modulates and demodulates radio frequency (RF) signals. The RFID tag further includes an antenna for receiving and transmitting signals over relatively short distances. The tag's data / information is stored in non-volatile memory. Fixed or programmable logic is provided to process the transmitted and sensor data.

[0050] In the illustrated embodiment of the gas monitoring system 500, the multi-unit charger 200 includes a housing 202 in which five charging slots 210 are formed. In the illustrated embodiment, the housing 202 is formed by two housing portions 202a and 202b. A unique RFID device / tag 230 is associated with each slot 210 of the charger 200. Figure 2B and Figure 2D As shown, in the illustrated embodiment, a communication device in the form of an RFID tag 230 is positioned near a charging coupler 240, which is connected to a line power supply via a printed circuit board 250.

[0051] When returned to one of slots 210, instrument 10 performs a “digital return” and is deassigned from the specific user, as further described below. To achieve seamless return with virtually no human intervention, the RFID tag 230 in charger 200 is integrated as an asset into the database of a software-based (e.g., web application-based) monitoring or management system 800 associated with the entity (e.g., facility or company).

[0052] When instrument 10 is inserted into charging slot 210, RFID device 60 communicates with / reads from a corresponding communication device in the form of charger tag 230. In several embodiments, data transmitted from the RFID tag (or other communication device) of this system includes a universally unique identifier or UUID of the RFID device / tag (which is, for example, a 128-bit tag used for information in a computer system). The UUID or other unique identifier of charger tag 230 is associated, for example, with information about charger 200 (including information identifying charger 200 as a physical asset) stored in a database of management system 800. When the UUID or other unique identifier is transmitted from gas monitoring system 500 to management system 800, one or more algorithms of system 800 are executed by the processor system of this system, and a determination is made as to whether charger 200 is a physical asset based on the information stored in the database. Thus, the information transmitted by RFID device / reader 60 enables the identification of multi-unit charger 200 as a valid device (i.e., not any random charger, but a charger as a correct physical asset). Upon determining that charger 200 is a valid device, instrument 10 is designated for return by management system 800 (i.e., electronic or digital), and instrument 10 is deassigned from the user to whom it was last assigned. Data transmission between charger 200 and instrument 10 is handled by... Figure 3 Arrow A is shown in the diagram.

[0053] In several implementations, instrument 10 can be placed in any charger registered as a physical asset to an entity's system / account for return / deallocation. If, in several implementations, the instrument is placed in an unregistered charger, the instrument will not be designated for digital return, and the instrument will not be deallocated from the designated user. Again, by means of, such as Figures 2A to 2DChargers such as multi-unit chargers 200 are registered to an entity's system / account in management system 800, with each RFID tag 230 in charger 200 associated with that specific entity. When instrument 10 is returned to any charging slot of a registered charger such as charger 200, instrument 10 reads the RFID tag 230 of the associated slot 210 where it is docked, seated, or returned, and management system 800 deassigns user / worker information previously associated with instrument 10 (discussed further below). System 500, in conjunction with management system 800, ensures a match between the entity system / account associated with instrument 10 and the entity system / account associated with charger 200, and facilitates the assignment / deassignment process.

[0054] For example Figure 3 As shown in the implementation of system 500, information associated with personal user data can be transmitted substantially automatically via, for example, card 600 (or other objects or items carried (including worn) by the user; including communication devices, such as RFID devices / tags 610). In this respect, when card 600 is placed in proximity to RFID reader 60, personal user data (associated with the user, such as identity, entity affiliation, etc.) can be transmitted as... Figure 3 Arrow B indicates that the data is transmitted to the RFID device / reader 60 of instrument 10. In several embodiments, the data transmitted from the tag includes the UUID or other unique identification information of the RFID device / tag 610. The UUID or other unique identification information of the RFID tag 610 is associated with information about an individual user in the database of management system 800. In this respect, when a user / worker removes instrument 10 from slot 210 of charger 220, instrument 10 reads the user's information (e.g., read from card 600 when approaching instrument 10), and instrument 10 is designated as assigned to the user. Instrument 10 will remain assigned to the user until instrument 10 is placed in one of the slots 10 of verified charger 100 and deassignment occurs as described above.

[0055] As described above, allocation and deallocation can be determined / controlled by transmitting identifiers (e.g., universally unique identifiers or UUIDs) of RFID tags or other communication devices associated with instrument 10, charger 200, card 600, and / or other devices. Identification and / or other information associated with instrument 10, charger 200, and personal user card 600 are stored in the software database system of management system 800. For example, when transmitting a UUID associated with one of the RFID tags 230, a cloud-based software system, using software algorithms, checks this information against stored records to determine if it is a valid allocation or deallocation, and then an appropriate command can be sent back to instrument 10. These commands include, for example, "Instrument xxx is now allocated to John Doe" or "Instrument xxx is no longer allocated."

[0056] In a typical user work cycle, the user may begin the cycle, for example, by removing instrument 10 from the charging slot and communicating with card 600, as described above, thereby assigning instrument 10 to the user. For example, the user may then be instructed to dock instrument 10 with slot 310 of calibration station 300 for a crash test. After a successful crash test, the user can continue their workday using instrument 10, which has been assigned to the user and monitored by system 500. As described above, at the end of the shift, instrument 10 is returned to the valid charger 200 and deassigned from the user.

[0057] The robust allocation and return / deallocation process provided by System 500 and Management System 800 can be used to associate all device / instrument data points (which can be transferred directly from Instrument 10 to Management System 800 via intermediate devices) with a specific user / worker (when the instrument is allocated to that specific user / worker) without adding indirect labor. Such data points include, but are not limited to, gas exposure, test compliance, safety behavior, and location data. Gas detection instruments and related accessories are typically shared by multiple users within a facility. Using System 500 in conjunction with Management System 800, one can aggregate all data from a group of gas detection instruments around a specific user, rather than just aggregating data around a specific instrument. In System 500 and the associated methods described herein, users do not need to change their workflows to complete the allocation / deallocation process described herein. Users simply place Instrument 10 into Charger Slot 210 at the end of their shift as usual, and allocation is automatically performed via System 500. Similarly, allocation is automated when a user removes Instrument 10 from Charger Slot 210 at the start of their shift.

[0058] In several embodiments, a locking setting is provided in the software stored in the storage system 44 of instrument 10. If such a locking setting is enabled, instrument 10 will not enter normal operating mode until it is assigned to an authenticated user. In several embodiments, if the locking setting is enabled and instrument 10 is powered on and not currently assigned, it will enter a locked state. Once instrument 10 is assigned, it will not enter a locked state while powered on until it is deassigned via communication with the authenticated charger 200 or by other means (e.g., upon receiving a direct command from the management system 800 or from an alternative path). Once instrument 10 reads, for example, an RFID tag 610 previously registered in or associated with an entity in the database of management system 800, instrument 10 unlocks and enters normal operating mode. In several embodiments, for added security, instrument 10 unlocks, for example, upon reading any tag conforming to the ISO 15693 standard, and enters measurement mode upon unlocking. However, if the management system 10 determines that the read tag is invalid, the management system 800 can send a duplicate push alarm to the instrument 10, indicating that an invalid tag has been used to unlock the instrument 10, and the instrument 10 will not be marked as assigned. The instrument 10 will be locked the next time it is powered on because it was not correctly assigned. The system 500, in conjunction with the management system 800, performs checks to ensure that tag assignment is valid. Again, tags read by the RFID device / reader 60 of the instrument 10 must be assigned to the same entity system / account (e.g., a facility-specific system / account) to which the instrument 10 is assigned.

[0059] In addition to transmitting information from card 600 to instrument 10, information can also be transmitted from the user's card 600 to the user's personal communication device 700, such as... Figure 3 As indicated by arrow C. The personal communication device 700 can be, for example, a device that supports Near Field Communication (NFC) / RFID, such as... Figure 3Element 710 is schematically represented. Furthermore, personal communication device 700 can receive data from instrument 10 via RFID communication from RFID tag 60' or other communication devices, as shown by arrow D. Personal communication device 600 (e.g., smartphone) can be used, for example, to manage RFID tags and associate data with such tags in management system 800. In this regard, an application or app can be downloaded (e.g., from management system 800), through which personal communication device 700 can be used, for example, to set / program RFID tags or other communication devices to, for example, associate the associated user's personal / identification information or data with the UUID of other communication devices of RFID tag 610 or card 600. The mobile app on personal communication device 700 can be used, for example, to download workforce rosters from management system 800. Placing personal communication device 700 in proximity to card 600 can be used to achieve pairing, for example, in the cloud.

[0060] like Figure 3 As shown, devices in system 500 can connect to the facility network and the Internet / cloud via various wired and / or wireless communication protocols / connections, including, for example, Ethernet, Wi-Fi, cellular (e.g., CAT-M for IoT (Internet of Things) cellular connections from a large number of devices), etc. For example, instrument 10 can utilize a CAT-M connection to transmit data (by... Figure 3 (Indicated by arrow E in the diagram), such as real-time instrument data, instrument logs, docking status, cylinder status, instrument configuration updates, and data used for assignment / deassignment. Instrument 10 can, for example, receive data (from... Figure 3 Arrow F in the diagram indicates data such as instrument configuration, instrument firmware update commands, updated alarms (e.g., evacuation alerts), and allocation / deallocation data. Instrument 10 can further receive data (via the paths indicated by arrows G and H), such as instrument firmware update packages. In several embodiments, all data transmitted between instrument 10 and management system 800 via the cloud occurs over a cellular / CAT-M or 2G connection. If this connection is lost, data / information can be stored (e.g., on instrument 10) until the cellular connection is re-established. In other embodiments, data such as... Figure 3 The diagram illustrates redundant communication paths using alternative connection pathways and / or protocols. Data communication between the personal communication device 700 and the cloud / management system 800 is handled by… Figure 3 The arrows I and J in the diagram represent...

[0061] The management system 800 (which may include, for example, a computer or multiple interconnected / networked computers) provides a centralized destination for managing / monitoring a fleet of gas detection instruments and their accessories at the facility. In various embodiments, the management system 800 is accessible, for example, via account login from facility computers, mobile devices, etc. Real-time notifications, instrument configuration, queue management, and related contextual reporting may be provided, for example, via a system / grid. The management system 800 may, for example, execute a web-based application to transmit data to system 500 (manufactured by…). Figure 3 (The arrow K in the image indicates) and receives data from system 500 (by...) Figure 3 The arrow L in the image represents (the arrow L in the image).
