[0018] Detailed Description

[0019] Although terms such as “first” and “second” may be used in this disclosure, it should be understood that those terms are used in their relative sense only unless otherwise noted. As used herein as a modifier to a property or attribute, the term “generally”, unless otherwise specifically defined, means that the property or attribute would be readily recognizable by a person of ordinary skill but without requiring a high degree of approximation (e.g., within + / - 20 % for quantifiable properties). The term “substantially”, unless otherwise specifically defined, means to a high degree of approximation (e.g., within + / - 10% for quantifiable properties). The term “essentially” means to a very high degree of approximation (e.g., within plus or minus 2 % for quantifiable properties); it will be understood that the phrase “at least essentially” subsumes the specific case of an “exact” match. However, even an “exact” match, or any other characterization using terms such as e.g. same, equal, identical, uniform, constant, and the like, will be understood to be within the usual tolerances or measuring error applicable to the particular circumstance rather than requiring absolute precision or a perfect match.

[0020] FIG. 1 illustrates an example environment in which systems and methods herein may be particularly useful. A number of firefighters 130 may arrive at a location 100 where an active fire 140 is in progress. A supervisor or site manager 120 may be responsible for dispatching or assigning individual firefighters 130 to different tasks. Each firefighter 130 maybe equipped with a self-contained breathing apparatus (SCBA) which is designed to provide clean air for a firefighter to breath. An SCBA may also include other sensors, such as motion detectors or other sensors which may help to indicate that a firefighter 130 is in distress.

[0021] FIG. 2 illustrates an example SCBA system in accordance with embodiments herein. However, it is expressly contemplated that other SCBA configurations may also benefit from systems and methods described herein. Additionally, while some components of SCBA system 200 are called out in FIG. 2, it is expressly contemplated that SCBA system may have additional components. SCBA system 200 includes an SCBA with a harness assembly 202 which a firefighter (e.g., firefighter 130) wears during a fire or other hazardous environment. SCBA also includes an air cylinder 204 configured to provide an air source to a respirator or mask (not shown) worn by firefighter 130.

[0022] SCBA system also includes a backframe 220. The backframe is a physical structure to which other components can be mounted, such as pressurized air cylinder 204. There may also be a sensor module 230 coupled to backframe 220. Sensor module may include a number of sensors. A location sensor, such as a assistance. Sensor module 230 may also include a motion sensor, such as a vibration sensor or accelerometer which may trigger an alarm or activate a position signal generator if an individual wearing system 200 has been motionless for an amount of time that may indicate a “person down” situation, e.g., that the individual wearing system 200 is in need of assistance - e.g., they have fallen unconscious, been pinned, etc. Such an alarm may also be manually triggered. For example, if an individual is pinned under debris, they can manually activate an alarm or rescue signal. Other sensors may also be present. For example, sensor module 230 may be powered by a battery pack.

[0023] SCBA may also include a device interface 240, which may enable wireless communication between firefighters 130 and supervisors. Wireless communication may include communication using any suitable wireless communication protocols including, but not limited to, WiFi™, ZigBee, Bluetooth®, Bluetooth LTE™, radio, or another suitable protocol.

[0024] SCBA system 200 has several components or subsystems that, if not fully functional, can present a safety risk to an individual. For example, if air cylinder 204 has a leak, an individual may run out of air too soon. If a low pressure signal for tank 204 is not functional, an individual may run out of air before they leave a fire scene or other hazardous area.

[0025] A low-pressure signal may be delivered by a whistle, for example as described in PCT Publication WO 2023 / 152609, published August 17, 2023, or using other suitable audio, visual or haptic feedback. An audible whistling sound may be easier for an SCBA wearer to hear and respond to in a loud environment. Particularly in low visibility environments, such as in an active firefighting operation, blinking lights may not be seen and haptic feedback may not register for a user in motion who is wearing thick or bulky garments. An audible, uniquely identifiable signal may allow for a user to get to safety before the air pressure in an air tank drops too low.

[0026] Similarly, if a position sensor or motion sensor is not functional, it may not be possible for other individuals to rescue a wearer of system 200 in time.

[0027] The United States has roughly 1 million firefighters, 65% of whom are volunteers or only part time. For these individuals, the process of checking the functionality of each piece of equipment is not second nature. Considering the importance of each part of the SCBA system 200, it is desired to have a system that is easy to use that walks such users through the safety checks required for SCBA system 200 prior to use.

[0028] Currently, the process of checking equipment involves a lot of manual steps, and logging the results of each step on paper. Even for veteran firefighters, it is possible to accidentally skip a step. A system is desired that can automate at least some of the equipment safety checks and logging steps without encumbering a veteran or professional user of SCBA system 200. Additionally, for veteran users of an SCBA system, systems and methods herein may the system check easier, enable more consistency and provide a convenient documentation process for risk management and proof of compliance.

[0029] Embodiments herein provide an SCBA console 210 that interfaces with the SCBA system with a pneumatic connection and an electronics connection that receives sensor signals from the sensor module and a pressure gauge that can be used to determine an air pressure of tank 204. A user would need to pressurize the SCBA, watch the pressure gauge for a period of time, and determine whether the change was sufficient to fail the test.

[0030] SCBA console 210, as described in greater detail herein, automates the process of checking several different components of SCBA system, including checking the air delivery system for leaks. SCBA console 210 is programmed to guide a user through the steps of an equipment check routine while logging testing results.

[0031] SCBA console 210, in accordance with embodiments herein, includes an operational testing mode configured to automatically proceeds through operational testing for a number of subsystems. SCBA console 210 may automatically collect test results as operational testing proceeds. SCBA console 210 may, during operational testing, automatically end testing if a necessary subsystem fails an operational test. In the operational testing mode, the SCBA console 210 may provide prompts and / or guidance as a user’s action is needed (e.g. opening or closing a valve, reporting whether a whistle sounds or not, etc.). For newer users, having an SCBA console that can guide them through the operational testing process for all necessary subsystems and record testing results may increase testing compliance. For veteran users, having results recorded automatically removes a step and increase accuracy and auditability of testing. For fire stations, having testing data may assist in incident reporting and / or management as well as potentially identifying systems needing maintenance or replacement.

[0032] In some embodiments herein, a user may be able to practice and / or preview the testing mode using an application that replicates prompts and / or guidance of the operational testing mode using a computing device with a display component.

[0033] FIGS. 3A & 3B illustrate an SCBA console in accordance with embodiments herein. As illustrated, in some embodiments an SCBA console is a handheld console, e.g. is sized and shaped to be held by an individual. In some embodiments the SCBA console comprises an ergonomic design feature. FIG. 3A illustrates a perspective view of an SCBA console 300. SCBA console 300 includes an analog pressure gauge 304 that couples to the air circulation system using pneumatic connection 312. SCBA console 300 receives sensor signals, e.g. from a sensor module associated with an SCBA system associated with console 300.

[0034] SCBA console 300, however, includes a number of digital components as well. SCBA 300 is programmed to, using menu navigation actuators 302, guide a user through a number of equipment checks. Menu navigation actuators 302 are illustrated as buttons that can be depressed to indicate a user selection. However, it is expressly contemplated that other I / O mechanisms may be used such as toggles, scroll wheels, or digital representations of buttons, switches, toggles, scroll wheels, etc.

[0035] SCBA console 300 includes a display 306 which may display a number of communicated or sensed information on a display 306, discussed in greater detail in FIG. 3B. Information for display 306 may come from a sensor module associated with SCBA console 300, from a sensor module associated with another firefighter, from a separate device using a wireless communication protocol, or another suitable source. SCBA.

[0036] SCBA console 300 also includes an alarm 310 that a user may manually trigger in case rescue or assistance is needed.

[0037] FIG. 3B illustrates an example user interface that may be presented on an SCBA console 350. SCBA console includes a digital user interface 390, which may present a menu that can be navigated by a user, for example using menu navigation features 352. Navigation features 352 are illustrated as physically depressable buttons. However, it is expressly contemplated that any suitable user input mechanism may be used.

[0038] Display component 390 can present a number of indications to a user that can be received from a sensor module or other suitable source. A buddy light 372 may be present to allow a user to visually see the status of some functions associated with a partner. In an IDLH atmosphere, for example, firefighters use a buddy system. Display 390 may display positional information, such as a compass reading 362.

[0039] A current air pressure may be displayed as an air pressure readout 364. Additionally, a time to whistle 376 may be illustrated. A “whistle time” may be customizable. For example, different jurisdictions have different requirements about how a user of an SCBA should respond as their remaining air runs low. For example, it may be a requirement for a firefighter to be back out of a fire or other hazardous situation before their remaining air falls below 10:00 minutes remaining. A whistle (or other audiovisual or haptic feedback mechanism) may be programmed to provide an alert at 10:00 minutes remaining. The time to whistle 376, then, indicates a time left until 10:00 minutes remaining.

[0040] Display 390 may display an alarm or alert. For example, a distress signal alert 466 may be displayed if a distress signal unit is activated, e.g. through a manual alarm actuator 360, or after a motion sensor fails to detect motion for a period of time. An evacuation indicator 368 may signal that an evacuation order has been given and that the individual needs to leave the building or area as soon as possible. In some embodiments, SCBA console includes an internal temperature sensor (not shown) which senses a temperature of the SCBA console. If the temperature of the SCBA console nears or exceeds a safe operating temperature (e.g., 170°F).

[0041] Some SCBA systems are equipped with an electronic personnel accountability report (ePAR), which may allow for a supervisor, site manager or incident commander to wirelessly request a status update. An ePAR indication 378 may light up, blink or otherwise indicate that the PAR request has been received by the SCBA console. The user may be able to acknowledge the PAR request using one or more of navigation features 352.

[0042] SCBA console 350 may also include a telemetry system, which may allow for transmission of SCBA data, e.g. Air Cylinder Pressure, Air-Pak ID, an end of service time indicator, Biometrics, System health or other relevant information. The telemetry system may allow for transmission of data using radio frequency (RF) or another suitable wireless communication protocol.

[0043] As noted in FIG. 2, an SCBA system may include a sensor module. Sensor module, and potentially other components of an SCBA system may be powered by one or more battery units, which may be rechargeable battery units, in some embodiments. A battery unit may include multiple batteries in a pack or may display a remaining bater life.

[0044] While console 350 includes a display 390 with preset indicators and text fields, it is expressly contemplated that other arrangements, and other display configurations are possible.

[0045] FIG. 4 illustrates an exemplary method of conducting an equipment check on an SCBA system. Historically, the illustrated blocks 410-460 represented individual equipment checks that an individual would need to do manually. The results of each check would need to be recorded, and decisions about whether equipment meets expectations had to be made by the individual. Each of blocks 410-460 represents a number of steps that must be taken to perform a safety check for a particular piece of equipment or system. Blocks 410-460 are illustrated and described in a particular order. However, it is expressly contemplated that each equipment check operation can occur in any suitable order. Embodiments herein include an SCBA console configured to, when in an operational testing mode, guide a user through each equipment check operation, automatically record results of each equipment check operation, and, if appropriate, automatically advance from a current to a subsequent equipment check operation. In some embodiments herein the system, instead of automatically advancing, automatically ends an operational equipment check if an equipment system fails.

[0046] At block 410 a batery is checked. Each SCBA includes a sensor module that has one or more electrically-powered sensors. One or more bateries may be used to power the sensor module and / or other electronics in an SCBA system such as, for example, an SCBA console. Checking a batery may include checking a remaining batery life before batery recharging or replacement is required.

[0047] At block 420 a motion sensor is checked. A motion sensor may provide an indication that a user has fallen unconscious or is stuck. Information from the motion sensor may be used to trigger an alarm or an alert that the user is in need of rescue or assistance. The motion sensor may have a pre-alarm seting, in some embodiments, which corresponds to a first no-movement detected threshold (e.g. 20seconds) as well as a full alarm, which corresponds to a second, higher, no-movement detected threshold (e.g. 12 seconds, for a total of 32 seconds).

[0048] At block 430 an automatic alarm system is checked. The automatic distress signal unit (also referred to as a personal alert safety system) sends out the alert or alarm in response to the motion sensor detecting no motion. The alarm might be a sound audible to those in the vicinity of the user or a signal that can be picked up by sensors associated with other users nearby, e.g. an SCBA console associated with a different user.

[0049] At block 440 a manual alarm system is checked. While a distress signal unit may generate an indication based on a motion sensor detecting no motion, it may also be possible for a user to cause an alarm to start manually. For example, a manual alarm actuator may be present on a SCBA console that allows a user to trigger an alert that rescue or assistance is needed.

[0050] At block 450 the air delivery system is checked for leaks. Breathable air is provided to a user from an air cylinder using a breathing system. The air cylinder may be pressured up to 5500 PSIG, for example, while other component may be pressurized to a lower degree. FIGS. 5A-5B illustrate how systems and methods herein may simplify the leak test for SCBA users. SCBA includes a whistle that audibly sounds when air pressure falls below a certain threshold. However, other end-of-time indicators may also be used.

[0051] FIGS. 5A-5B illustrate methods of conducting an air leak test for an SCBA system. FIG. 5A illustrates a manual approach while FIG. 5B illustrates an automated approach.

[0052] At block 510 a user opens a system valve to pressurize the air delivery system.

[0053] At block 520 the user reads and records a pressure displayed on a pressure regulator. If the pressure regulator is an analog pressure regulator, this can introduce human error.

[0054] At block 530 the user waits. For example, the user may wait 20 seconds so that, if a leak is present, it can be detected.

[0055] At block 540 the user reads the pressure regulator again. If the pressure regulator is an analog pressure regulator, this can, again, introduce human error.

[0056] At block 550 the user checks a change in pressure from the first reading to the second reading. If the pressure has dropped significantly (e.g., more than 20 PSI), this may indicate that there is a leak. At block 555, the user determines whether or not the pressure drop is lower than a maximum allowable pressure drop.

[0057] At block 560 the user records the result of the leak test. This is often done on a paper log.

[0058] The method illustrated in FIG. 5A requires a user to accurately read an analog pressure regulator, consistently wait for the required hold time to keep measurements accurate from test to test, and determine whether or not the equipment is safe to use (e.g., a leak is either not present or not significant enough to be of concern).

[0059] The method illustrated in FIG. 5B, which uses a SCBA console to automatically take pressure readings before and after a waiting period timed by the SCBA console. In some embodiments the SCBA console also automatically determines whether the equipment passes or fails a leak test.

[0060] As noted previously, many individuals using SCBA systems perform equipment checks sporadically while others perform equipment checks daily. The method of FIG. 5B can be completed in less time and with fewer errors, making it more accurate for infrequent SCBA users and more efficient for regular users.

[0061] At block 572 a user initiates the leak test. In some embodiments, a user initiates the leak test by selecting a “leak test” from a list of equipment check options on a display, using a suitable I / O mechanism such as a scroll wheel, button, touchscreen, keyboard, etc. In some embodiments, an SCBA console has a present order of equipment checklist items (e.g., those listed in FIG. 4, for example) and a user initiates the leak test by completing a preceding equipment checklist item.

[0062] At block 574 a first pressure reading is automatically captured after a user has opened a valve to allow air to pressurize the air delivery system. The SCBA console, in some embodiments, is pneumatically coupled to the air delivery system and, therefore, can capture a pressure reading automatically and precisely.

[0063] At block 576 a second pressure reading is automatically captured. The SCBA console may take the pressure reading after a set amount of time. For example, a timer may start when the first pressure reading is recorded and, after a set period of time (e.g., 20 seconds), the second pressure reading is automatically reading is removed by the SCBA capturing both pressure readings and running a timer in between.

[0064] At block 578 a result of the leak test is provided. For example, a “pass” or “fail” indication may be presented on a display. In some embodiments, a detected pressure difference is presented on a display to a user.

[0065] At block 580 the result of the leak test is automatically logged. The result may be sent to a second device for storage such that, should an incident occur, the result of the equipment check can be accessed by an incident management software or supervisor.

[0066] FIG. 6 illustrates an exemplary process of conducting a whistle check for an SCBA system in accordance with embodiments herein.

[0067] At block 1510, a whistle check operation is initiated. The whistle check may be the first subsystem to be checked, in some embodiments. In such embodiments, initiating the whistle check operation includes the SCBA console being configured to enter an operational testing mode and automatically start the process of checking whistle functionality. In some embodiments, initiating the whistle check operation includes the SCBA console, while in an operational testing mode, automatically advancing from a previous equipment check operation and starting the whistle check operation.

[0068] At block 1520, in some embodiments, the user is prompted to open a valve of a pressurized tank to allow air to start flowing. However, it is expressly contemplated that, in some embodiments, the SCBA console may detect, or receive an indication, that the air delivery system is pressurized without user intervention.

[0069] The SCBA console monitors the pressure in the air tank and, after a sufficient pressure drop, the whistle should sound. The user may be asked to confirm whether the whistle sound was heard, in some embodiments. The user may be prompted to close the valve to stop the flow of air.

[0070] At block 1530, a test result indication is received. Receiving a test result indication may include receiving a user indication that the whistle has sounded - e.g. using a suitable user input mechanism (e.g. button, scroll wheel, etc.). Receiving the test result may also include other sensory input.

[0071] At block 1540, the SCBA console, in the operational testing mode, evaluates the test result indication. If the whistle sounded as expected, the SCBA console, in the operational testing mode, proceeds to block 1560, and automatically advances to test the functionality of another subsystem. In some embodiments, however, the whistle check is the last subsystem in the series of subsystems undergoing operational testing. In such embodiments, instead of proceeding to the next subsystem test module, the SCBA console concludes the testing and exits the operational testing mode. Test results 1565 for the whistle check are automatically recorded.

[0072] At block 1540, if the whistle did not sound as expected, the SCBA console automatically proceeds to block 1550 and ends functionality testing. In some embodiments, ending functionality testing includes the SCBA console automatically exiting the operational testing mode. results on a memory of the SCBA console in some embodiments. In some embodiments, recording test results may include delivering the results, using a wired or wireless protocol, to another device. For example, the console may be communicably couplable to a sensor module (e.g. sensor module 230). The SCBA console may communicate results to the sensor module, or another device, using any suitable wired or wireless protocol.

[0073] Processes described with respect to FIGS. 5-6 are described as automatically proceeding, in some embodiments. However, it is expressly contemplated that automatically proceeding may include presenting an indication to a user - e.g. test results, an indication of the next test module, etc. Such indications may be presented for a period of time, or may require the user to provide a user indication to proceed.

[0074] FIGS. 7A-7D illustrate example functionality of an SCBA console in accordance with embodiments herein.

[0075] An SCBA console 600, in embodiments herein, combines a digital display 610 and an analog display 620 in one device. Analog display 620, in embodiments herein, is a pressure gauge. Display 610 may display pressure information, as illustrated in FIG. 7A. However, it may also display a number of other indications. SCBA console 600, in embodiments herein, is a component of an SCBA system that a user wears into a fire or other hazardous scenario. SCBA console 600 may be manufactured from materials designed to withstand high temperatures to meet the heat and flame standards of NFPA 1981 and 1982 standards. For example, SCBA console 600 may be made of materials that can withstand up to 170° F. Display 610 is configured to function at high temperatures. In addition to providing alerting, location and data transfer functionality in a hazardous area, the digital display may be easier to see and read in a low-visibility environment (e.g. smoke- filled space) than the analog gauge.

[0076] During an equipment check, a status indication 602 may be presented on a display. For example, FIGS. 7A-7B illustrate two user interfaces that may be encountered during an air leak check. The measured pressure is indicated on screen 610 as well as gauge 620.

[0077] FIG. 7B illustrates a results interface of the air leak test. In the event that the air leak test results in a pass (e.g. indication 632), SCBA console 600 may move to a subsequent equipment check step. In the event of a failure, the SCBA console 600 may exit an equipment check and / or provide a failure indication.

[0078] As illustrated in the transition from 7A to 7B, test results are automatically logged, with a confirmation 634 presented on a display.

[0079] After a completion of the air leak check, in an example equipment check list, a whistle check may come next, as illustrated in FIGS. 7C-7D. However, it is expressly contemplated that an equipment checklist, such as that illustrated in FIG. 4, may have items that can be completed in any order and that systems and methods herein are not limited to a specific order. In some embodiments, an equipment check module may automatically proceed to a next equipment check. In some embodiments, at least some user input is required before the equipment check module proceeds. process. In response to a passed air leak test, the equipment check module has automatically moved forward to a whistle check. When the air cylinder is reduced to a certain pressure indicative of an end-of-service time, an alert may sound indicating to a user that it is time to evacuate. In some jurisdictions, the user is required to evacuate prior to the air running out. For example, a user may be required to exit a fire or other hazardous area before their air is reduced to a 10:00 remaining time, at which time a whistle or other alarm is triggered. However, other triggers are expressly contemplated. For example, a whistle may be set to alarm when a pressure is reduced to 50%, or 30%, or 10%, etc. of a rated cylinder pressure. Other standards may be used based on jurisdictional or local regulations.

[0080] As illustrated on display 640, a whistle may be configured to sound when an air pressure reaches 45 Bar. In some embodiments, the pressure at which the whistle sounds is configurable. For example, the whistle may be programmed to go off when an air level reaches 20:00 minutes remaining or 15:00 minutes remaining or only 5:00 remaining, etc.

[0081] Some equipment check items, like the whistle check, require a user input, e.g. indicating that “yes” the whistle sounded audibly. The SCBA console may prompt a user for feedback, as indicated in display 640. The user may provide feedback using one or more user input mechanisms such as buttons, scroll wheels, keyboards, switches or digital representations thereof.

[0082] When the equipment check for the SCBA system is completed, a user may see a completed check indication 650 on the display. The SCBA console may automatically exit the equipment check module such that it can receive and display information during regular operation.

[0083] FIG. 8 illustrates an SCBA console in accordance with embodiments herein. SCBA console 700 includes a user interface 710 with physical and digital display components. SCBA console 700, in some embodiments, has internal sensors and / or communicates with external sensors. External sensors may include environmental sensors and / or SCBA sensors, for example mounted to a physical back frame or otherwise communicably coupled to SCBA console 700. An SCBA system may include a temperature sensor 770, in some embodiments. An SCBA system may include a motion sensor 792, illustrated as part of SCBA console 700. An SCBA console 700 may include one or more user input / output (I / O) mechanisms 776. SCBA console 700 may include, or is communicably coupled to, a speaker 788, which can provide audible indications. In some embodiments, SCBA console 700 includes, or is communicably coupled to, a whistle or other alarm system.

[0084] SCBA console 700 has an electrical connection 782, such that signal receiver 732 may receive signals from one or more sensors. SCBA console 700 has, or is coupled to, a power source 780. SCBA console 700 includes a pneumatic connection 784 which couples to an air delivery system.

[0085] At least some of the user interface elements are generated, or actuated, by a user interface generator 730. For example, an EVAC indication 730 may be actuated, by indication actuator 734, when signal indication receiver 732 receives a sensed temperature from temperature sensor 770 indicating that the SCBA may be actuated based on a sensed remaining battery life, etc.
