Abstract: A safety system includes a plurality of alert devices associated with a unique identifier. Each alert device includes a user interface, a wireless transceiver, and a processor communicably coupled to the wireless transceiver. The processor of at least one alert device is configured to generate an alarm signal indicative of an alarm state, and transmit the alarm signal including the unique identifier of the at least one alert device to the wireless transceivers of the other alert devices. The processor of each of the other alert devices is configured to receive the alarm signal from the at least one alert device, determine a link quality indicative of at least a relative distance between the at least one alert device and the corresponding other alert device, and display, via the user interface, an alert message including the unique identifier of the at least one alert device and the corresponding link quality.

Abstract: A safety circuit for a Personal Alert Safety System (PASS) device includes a safety logic circuit and an alarm circuit. The safety logic circuit is communicably coupled to the PASS device. The safety logic circuit includes a timer configured to determine a time elapsed since the timer has been last reset. The safety logic circuit is configured to switch from an off state to an on state upon receiving an activation signal from the PASS device and reset the timer upon switching to the on state, generate a trigger signal in response to the timer exceeding a time threshold, and reset the timer upon receiving a reset signal from the PASS device before the timer exceeds the time threshold. The alarm circuit is communicably coupled to the safety logic circuit and configured to generate an alarm signal upon receiving the trigger signal from the safety logic circuit.

Abstract: A monitoring unit for wireless communication with a plurality of self-contained breathing apparatus (SCBA) units configured to form a network is provided. The monitoring unit includes a communication interface and processing circuitry. The processing circuitry is configured to receive, via the communication interface, a plurality of updates from each of the SCBA units where each update includes information indicating at least one communication link quality to at least one other SCBA unit. The processing circuitry is further configured to determine at least one distance from each SCBA unit to at least one other SCBA unit that is one hop away in the network based at least in part on the communication link quality. The processing circuitry is further configured to cause the determined at least one distance to be displayed.

Abstract: A system for use with a personal protective equipment (PPE) article includes a memory configured to store a user identification associated with a user of the PPE article. The system further includes a safety module configured to selectively generate an alert signal based on a motion status of the user of the PPE article. The system further includes a transceiver unit configured to wirelessly transmit and receive data. The system further includes a controller communicably coupled to the memory, the safety module and the transceiver unit. The controller is configured to retrieve the user identification from the memory upon receiving the alert signal from the safety module. The controller is further configured to convert the user identification into a speech data. The controller is further configured to transmit the speech data through the transceiver unit.

Abstract: A tracker device for a first responder including a radio configured to receive a first radio signal from an emitter, and receive a second radio signal from an unmanned aerial vehicle (UAV). The second radio signal includes at least one data packet including location information associated with the emitter. Processing circuitry in communication with the radio is configured to determine at least one location parameter associated with the emitter based on the first radio signal and the location information of the at least one data packet of the second radio signal.

Abstract: A personal multimedia communication system and network for emergency services personnel includes a plurality of personal communication systems linked together and to a base station in a network. Each personal communication system includes a PDA device mounted on a PASS control console, a video camera mounted on the PDA device, a GPS unit, a microphone, and other electronic devices. The various electronic devices are all communicatively connected to the PDA device. Data from the various devices may be collected in the PDA device and wirelessly transmitted to any other node or device in the network, including other personal communication devices. Each personal communication device may serve as a repeater, thus providing a wireless communications link between a device located out of range of the base station.
