[0015] Detailed Description

[0016] 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.

[0017] FIGS. 1A-1C illustrate example environments in which systems and methods herein may be useful. FIG. 1A illustrates an example storage arrangement for self-contained breathing apparatuses (SCBAs). Firetrucks often store SCBAs such that a user can easily don the harness straps 12 before standing up . A firetruck seat 10 may have a spring -loaded or other mechanical mechanism that releases in response to force (e.g. a user standing up or pulling away from seat 10). An SCBA, as illustrated in FIG. 1A, includes a pressurized air tank 14 mounted to a backframe 16. SCBA systems often include a number of sensors configured to sense signals relevant to the environment, SCBA functionality, or a wearer status (e.g. air pressure sensor, motion sensor, accelerometer, temperature sensor, etc.). In some embodiments, some SCBA sensors are built into a sensor module 18.

[0018] FIGS. IB and 1C illustrate an SCBA system 100, 150 worn by a user 102, 152. SCBA systems 100, 150 are illustrated without a pressurized air tank to better illustrate some SCBA components.

[0019] An SCBA includes a backframe 104 to which components may be coupled, such as an air tank, communication components (e.g. radio, push-to-talk devices, speakers, etc.). A sensor module 108 is coupled to backframe 104 and may be communicably coupled to any of a display, a speaker, a communication component operating on a wireless communication protocol, an alarm, or another input / output component.

[0020] Sensor module is illustrated as having a battery compartment 114.

[0021] FIG. 1C illustrates a side view of an SCBA system 150. SCBA system 150 is designed to be wom by auser 152. When in use, apressurized air tank is held in place within the SCBA by strap 162. Sensor module 160 is illustrated, along with a battery compartment cap 164.

[0022] The illustrated SCBA model of FIGS. 1B-1C includes a battery compartment 114 configured to use non-rechargeable batteries. However, some SCBA systems include rechargeable batteries.

[0023] FIGS 2A-2B illustrate examples of a sensor module. Sensor module 200 is provided as one example configuration of a sensor module. However, it is expressly contemplated that systems and methods described herein may be useful for other sensor module configurations.

[0024] FIG. 2A illustrates a sensor module 200 that includes a sensor body 230. Sensor module 200 may have an antenna 220 in some embodiments. Sensor module includes a battery compartment 210. FIG. 2B illustrates an exploded view of a sensor module 250. Battery compartment 252 receives batteries that couple to metal contacts 256. Closures 254 (e.g., screws, bolts or another locking mechanism) are received by battery compartment 252 and close the battery compartment 252 from the environment.

[0025] One particular problem with powering a sensor module (and / or other electronic components) of an SCBA is that SCBAs are often exposed to hazardous or extreme environments - e.g. a fire, a chemical spill, etc. Battery compartments that house rechargeable or non-rechargeable batteries have ingress points. For example, if compartment 252 is not properly sealed, e.g. due to user error in applying closures 254 or age of the sensor module, air and water can get into the battery compartment. Additionally, by removing cap 164, for example, and then replacing it once batteries are replaced may also introduce ambient air, which may have some water content. As an SCBA is subjected to temperature swings (e.g. entering and then exiting a fire scene), moisture may cause corrosion and, overtime, malfunction.

[0026] Non-rechargeable batteries require scheduled maintenance to ensure that battery power levels are sufficient for the next user. Corrosion can cause battery power levels to drop rapidly and / or before an expected end-of-life.

[0027] A potential solution that has been tried is to instead use rechargeable batteries. A battery compartment is removed and placed in a charging station and charged using metal contacts. However, again, the introduction of any water near the metal contacts used for charging causes eventual corrosion. In addition to water, a sensor module exposed to a fire will also accumulate soot that can increase the speed of corrosion. Corrosion may require that contacts on the sensor module be regularly cleaned and / or corrosion removed by abrading contact surface.

[0028] A power solution is desired that does not expose a battery compartment or contacts to corrosive materials.

[0029] Systems herein provide sensor modules capable of wirelessly recharging. A rechargeable battery is sealed into the sensor module such that it is not easily removeable. The rechargeable battery charges wirelessly without any point of ingress of water and / or debris into the battery compartment as well. In some embodiments, ultrasonic welding is used to seal a battery into a battery compartment. If and when a battery needs to be replaced, e.g., reaches an end of service life, etc., the entire battery compartment is replaced with another unit.

[0030] Additionally, wireless recharging offers the potential for the sensor module to communicate data and / or receive data during a charging operation.

[0031] Systems and methods herein include an alignment feature that aligns transmission coils associated with the sensor module battery with transmission coils associated with a charging station. Alignment features may be, in some embodiments, mechanical, magnetic, or another suitable technology for maintaining alignment.

[0032] While embodiments of SCBAs have been illustrated, it is expressly contemplated that systems and methods herein are not limited to the illustrated SCBA arrangements and may be applied to other SCBA systems.

[0033] FIGS. 3A-3D illustrate sensor modules in accordance with embodiments herein. FIG. 3 A illustrates a sensor module 300 configured for wireless recharging. Sensor module 300 includes one or more transmission coils 304, 306 configured to couple to a power source. Wireless recharging, as described herein, may refers to an electromagnetic induction process or a capacitive coupling process. Sensor module 300 is illustrated in FIG. 3 A as having two transmission coils 304 and 306. However, it is expressly contemplated that, in some embodiments, sensor module 300 only has one transmission coil, e.g. 304 or 306. Transmission coils, as described herein, may be wound in a direction such that the coil is angled to a sensor module surface (e.g., coil 304) or in a direction such that the coil is parallel to the sensor module surface (e.g., coil 306). Wireless charging may require precise placement of sensor module 300 in order to ensure that a coil (304, 306) is properly aligned with a charging transmission coil on a power source. As illustrated in FIG. 3A, a male-female coupling may be used, with sensor module 300 illustrated as having an aperture, extending into a sensor module surface 302, configured to receive a protrusion on a power source. While a circular shaped aperture is illustrated in FIG. 3A, it is expressly contemplated that an orientation feature may be shaped in any suitable way - e.g. ovular, polygonal, or even an irregular shape. In some embodiments a non-circular shape may prove beneficial for ensuring proper orientation. Additionally, while an aperture is illustrated, it is expressly contemplated that, in some embodiments, the orientation feature is a protrusion extending outward from surface 302.

[0034] FIG. 3A illustrates an embodiment where a coil is wrapped around an alignment feature, it is expressly contemplated that an alignment feature may be elsewhere on sensor module. For example, surface 302 may not be completely flat. Raised features 310 may be received by corresponding apertures in a power source such that, when raised features 310 are received by corresponding apertures. While raised features 310 are illustrated, it is expressly contemplated that depressed features or apertures may be present on surface 302 and receive corresponding raised features or protrusions.

[0035] FIG. 3B illustrates a cross-sectional view 320 of a sensor module with an aperture 326 configured to be received by a protrusion 336 of a power source (not shown). Aperture includes at least one transmission coil (322, 324) configured to couple with a corresponding transmission coil (332, 334). Sensor module 320 is illustrated as having a piezo transducer 350. However, it is expressly contemplated that sensor module 320 may have two or more piezo transducers 350, in some embodiments.

[0036] In some embodiments, sensor module also includes a sensor module data transfer component 328 configured to couple to a power source data transfer component 338. When alignment features 326, 336 are in an aligned position, it may be possible, using a wireless communication protocol, to transfer data between data transfer components 328, 338. For example, sensor data, sensor module identify or other data may be transferred from module 320 to a memory associated with a power source associated with alignment feature 336. Sensor settings, software updates, a configuration change and / or other information may be transferred from a memory associated with a power source to module 320. In some embodiments, a first wireless communication protocol is used to transmit a sensor module identifier and, based on the identifier, a second wireless communication protocol (e.g. Bluetooth®, Bluetooth LTE®, NFC, RFID, Zigbee®, etc.) may be used to transfer data.

[0037] A data transfer coil may be positioned near a power transmission cable. For example, as illustrated in FIG. 3B, a data transfer coil 328 is positioned within coil 324 on a sensor module. However, it is expressly contemplated that, in some embodiments, data transfer coil 328 is positioned elsewhere. For example, in embodiments where sensor module includes at least two transmission coils (e.g. coils 322, 324 and / or 328), a coil configuration may be received from a power source, or communicated from the sensor module 320.

[0038] It is noted that in the embodiment illustrated in FIGS. 3A-3B that a transmission cable charges a sensor module directly, and indirectly charges the battery pack. However, it is expressly contemplated that a charging coil may be positioned such that a battery within battery compartment 340 is directly charged when sensor module 320 is aligned with a power source 336.

[0039] FIGS. 3C and 3D illustrate some potential placement options for a wireless charging feature (e.g. a transmission coil and an alignment feature) on a sensor module. A sensor module may be consider to have a “front,” illustrated in FIG. 3C on an opposite side of a “back,” illustrated in FIG. 3D. It may be preferred to have a wireless charging feature on whichever surface interfaces with a power source. For example, as discussed in further detail in FIG. 5, a sensor module may be configured to align with an alignment feature in a storage location (e.g., a chair as illustrated in FIG. 1, a storage rack, etc.) A placement on the “front” of sensor module (e.g. position 350) may make it easier to align sensor module for charging. As illustrated in FIG. 1, a “front” of a sensor module may face a storage location which could be equipped with a power source that, when aligned with an alignment feature of the sensor module, facilitates data and / or power transfer.

[0040] However, it is expressly contemplated that a wireless charging feature may be placed in any suitable location on a sensor module. A placement on a front surface 350 or a back surface 360 may be suitable. In embodiments where a battery is directly charged by wireless charging, a wireless charging feature may be positioned on or near a battery compartment, as illustrated by position 360.

[0041] However, in some embodiments, sensor module is configured to be removed from a backframe 380 and placed in contact with a separate charging feature.

[0042] Systems herein provide a battery pack having a wireless charging feature sealed herein. The seal may be any suitable seal. For example, a permanent seal such as an adhesive or a weld may be used - such as ultrasonic welding, for example. While ultrasonic welding is described herein, other sealing options are expressly contemplated including other welding techniques, adhesive or mechanical sealing options. For example, an o-ring or gasket, paired with screws or bolts may create a sufficient seal. However, mechanical, removeable seals may generate the undesired environmental ingress problems described herein. An adhesive that is sufficiently heat resistant and capable of adhering to all necessary components may be suitable.

[0043] FIG. 4 illustrates a method of charging an SCBA sensor module in accordance with embodiments herein. Method 400 may be used to wirelessly charge sensor models illustrated in FIGS. 1-3 or other suitable sensor module configurations.

[0044] At block 410 a battery is coupled to a power source. In accordance with embodiments herein, an SCBA battery is coupled to a power source while still coupled to the SCBA, as indicated in block 412. In some embodiments, a sensor module is removed from a backframe and charged separately, as indicated in block 414. Other charging arrangements are possible, as indicated in block 416. At block 420, one or more transmission coils associated with the battery are aligned with corresponding transmission coils associated with a power source. It is preferred that a transmission coil of the battery are aligned with a transmission coil of the power source. Therefore, a position and / or alignment feature may be provided to ensure a preferred position and / or orientation is achieved and maintained during charging. For example, a magnet may be used to align and maintain alignment of a battery transmission coil with a corresponding power source transmission coil during charging, as indicated in block 422. In some embodiments, a mechanical alignment feature may be used, as indicated in block 424, such as the protrusion / aperture described in FIGS. 3A-3D. In some embodiments, a mechanical “lock” may be used to ensure alignment, such as a 90° turn. It is expressly contemplated that other partial or complete turns (e.g., 360° or more) may be used as a “lock.” Other position / orientation mechanisms are also envisioned. For example a magnet may be used in conjunction with a partial or complete rotation of an alignment feature.

[0045] At block 430, the battery undergoes a wireless charging procedure. Recharging may entail directly charging the battery, as indicated in block 432, such that the battery in the battery compartment is directly coupled to the transmission coils, and such that power flows from the power source to the battery directly. In some embodiments, recharging may entail indirectly charging the battery, as indicated in block 434. For example, a power source may charge sensor module directly, which then charges the battery. Indirect charging may be preferred in some situations as directly charging a battery may cause unwanted heat to accumulate.

[0046] As used herein, wireless charging may refer to any power transfer operation that recharges a battery without the use of physical contact between corresponding transmission coils. Some example charging mechanisms include, but are not limited to: magnetic resonance charging, magnetic inductive charging, including near-field magnetic induction charging, uncoupled radio frequency wireless charging, radiative electromagnetic resonant charging and / or tightly coupled electromagnetic inductive charging. The battery and / or sensor module may physically touch a power source in embodiments herein, but a transmission coil associated with the battery does not contact a transmission coil associated with the power source.

[0047] At block 440, in some embodiments, data is transferred from the sensor module to a power source as indicated in block 442, from the power source to the sensor module, as indicated in block 442, or both. Configuration changes, firmware updates or new sensor settings may be communicated to the sensor module, for the example. Sensor signals relevant to SCBA function may be communicated to a computing device associated with the power source.

[0048] In some embodiments, a sensor module includes at least two transmission coils, a first may be used to transfer data to a computing device associated with the power source while the second charges the sensor module. Each of the two transmission coils, in some embodiments, can serve as either the power transfer coil or the data transfer coil. In some embodiments more transmission coils are present, e.g., such that a recharging operation goes faster, so more data can be transferred, or both.

[0049] FIG. 5 illustrates an SCBA storage environment in accordance with embodiments herein. SCBA charging station 500 is built into a firetruck seat 502, in some embodiments. Seat 502 includes cylinder locking mechanisms 510 which hold a pressurized air tank in place while the fire truck is in motion. As discussed above an applied force, such as a user putting on a harness and standing up, may be sufficient to cause locking mechanisms 510 to release. Locking mechanisms 510 may include magnets, spring-loaded clips, or another suitable releasable mechanism.

[0050] However, maintaining a position of the air cylinder may not be sufficient to ensure that the air cylinder, and / or the backframe does not rotate. Wireless charging requires a transmission coil associated with the sensor module and / or battery to be in a plane parallel to a plane of a power source. Additionally, the transmission coil associated with the sensor module and / or battery must be correctly positioned with respect to the power source.

[0051] In some embodiments, an alignment mechanism 520 may maintain a proper alignment in a position and orientation that facilitate wireless charging. Alignment mechanism 520 may include a magnet, a mechanical feature such as a protrusion or aperture that couples to a corresponding aperture or protrusion of a sensor module.

[0052] While a firetruck seat 502 is illustrated, it is expressly contemplated that a similar charging station may be used such that the proper orientation and position is maintained. For example, SCBAs may be stored in lockers, in a service bay, or otherwise in a position such that a cylinder is locked into place with locking mechanisms 510, or any other suitable mechanism.

[0053] FIG. 5 illustrates an embodiment where the battery and / or sensor module stays coupled to an SCBA system while charging. This may be preferable to ensure that recharging is possible without further action by a user. However, it is expressly contemplated that the sensor module may be separated from an SCBA system for charging. The sensor module may plug into a charging station located at a separate place in a fire truck, service bay, or other SCBA storage location. For example, sensor modules may be charged in a control room.

[0054] FIG. 6 is a block diagram of a sensor module for an SCBA system in accordance with embodiments herein. A sensor module 600 includes one or more sensors 602 powered by a battery 606. As used herein, the term “battery” is intended to include embodiments using a single battery, a battery pack, or other rechargeable power source. Sensor module 600 may also include, or be communicably coupled to a datastore 604 that stores, for example, sensor signals from sensors 602. Datastore 604 may also store an identifier for sensor module 600. Datastore 604 may also include other information.

[0055] A charging station 650 is configured to communicably couple to sensor module 600 such that power and / or data may transfer therebetween. Charging station 650 may have, or be coupled to, a datastore 652. Datastore 652 may include configurations for one or more sensors 602, firmware updates for one or more sensors 602 and / or sensor module 600, or other information.

[0056] A transmission coil 620 of sensor module 600 is configured to align with transmission coil 670 of charging station 650. A first alignment mechanism 610 may help maintain alignment between transmission coils 620, 630. In some embodiments, first alignment mechanism 610 couples to, or contacts, second alignment mechanism 660. In some embodiments, one of first and second alignment mechanisms 610, 660 is a protrusion and the other alignment mechanism is an aperture. In some embodiments, one of first and second alignment mechanisms 6106, 660 is rotatable such that a proper position and / or orientation is achieved when one of first and second alignment mechanisms is rotated with respect to the other.

[0057] While a single pair of transmission coils 620, 670 are illustrated, it is expressly contemplated that an additional pair of transmission coils may be present. Additionally, while transmission coil 620 is illustrated as having separate functionality than data transmission coil 630, it is expressly contemplated that, in some embodiments, a transmission coil may serve as either a data transmission coil or a power transmission coil. In some embodiments, a first pair of transmission coils (e.g. 620, 670) is used for charging based on a detected better orientation between coils 620 and 670 than between coils 630, 680. Multiple transmission coil pairs may help to ensure that charging of the sensor module 600 is possible if a correct position and / or alignment is not achieved.

[0058] Transmission coil 620 may couple to recharging circuitry of battery 606 directly in some embodiments. However such an arrangement may generate unwanted heat. In some embodiments, transmission coil 620 couples to recharging circuitry of sensor module 600, which then recharges battery 606.

[0059] As used herein, the term SCBA system refers to a self-contained breathing apparatus worn by an individual in a hazardous situation, such as a fire, a chemical spill, etc. SCBA systems herein may include a harness assembly that includes adjustable shoulder straps and / or hip straps configured to hold a pressurized air tank on a user’s back. SCBA systems herein include a pressurized air tank that is communicably coupled to a respirator, mask or facepiece worn by a user.

[0060] The pressurized air tank may be coupled to a backframe, which helps to reduce bouncing or jostling of the air tank. SCBA systems in embodiments herein may include a number of sensors. At least some of SCBA sensors are part of a sensor module. A location sensor, such as a GPS sensor or a position signal may be present to aid in finding an individual wearing an SCBA if they need 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 an SCBA has been motionless for an amount of time that may indicate a “person down” situation, e.g., that the individual an SCBA 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 manual activate an alarm or rescue signal. Other sensors may also be present. For example, the sensor module may be powered by a wirelessly rechargeable battery and / or battery pack.

[0061] SCBA may also include a device interface, which may enable wireless communication between SCBA users and / or other personnel. 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.

[0062] It will be apparent to those skilled in the art that the specific exemplary embodiments, elements, structures, features, details, arrangements, configurations, etc., that are disclosed herein can be modified and / or combined in numerous ways. In summary, numerous variations and combinations are contemplated as being within the bounds of the conceived invention, not merely those representative designs that were chosen to serve as exemplary illustrations. Thus, the scope of the present invention should not be limited to the specific illustrative structures described herein, but rather extends at least to the structures described by the language of the claims, and the equivalents of those structures. Any of the elements that are positively recited in this specification as alternatives may be explicitly included in the claims or excluded from the claims, in any combination as desired. Any of the elements or combinations of elements that are recited in this specification in open-ended language (e.g., comprise and derivatives thereof), are considered to additionally be recited in closed-ended language (e.g., consist and derivatives thereof) and in partially closed-ended language (e.g., consist essentially, and derivatives thereof). Although various theories and possible mechanisms may have been discussed herein, in no event should such discussions serve to limit the claimable subject matter. To the extent that there is any conflict or discrepancy between this specification as written and the disclosure in any document that is incorporated by reference herein but to which no priority is claimed, this specification as written will control.
