Abstract:
A method and device enables establishing radio communications on a trunked network using an inbound proxy. The method includes receiving, at a first subscriber device, a control signal from a base station on an outbound control channel of the base station. A request is then transmitted from the first subscriber device to the base station on an inbound control channel of the base station. Next, it is determined, at the first subscriber device, that the request was not received by the base station. The request is therefore re-transmitted from the first subscriber device to a second subscriber device on an inbound proxy control channel. The first subscriber device then receives a response to the request from the base station. The first subscriber device is thus able to subsequently establish radio communications on the trunked network via the second subscriber device.
Abstract:
A portable communication device (100) automatically determines user hydration levels while the device is being transmitted. The portable communication device comprises a humidity sensor (120) located by a microphone and touch sensors (124) located on a push-to-talk (PTT) button (110). Data is gathered during PTT switch activation (112). No additional steps are required by the user. Alerts (140) are provided when predetermined dehydration thresholds are approached.
Abstract:
A wearable safety apparatus includes a housing, a plurality of directional thermal imaging sensors mounted on the housing and facing outwardly away from the housing in a corresponding plurality of different directions towards thermal zones of a heat source. Each sensor detects infrared radiation (IR) intensity and generates an output indicative of a temperature of the detected IR intensity in a respective thermal zone faced by a respective sensor. An interface is mounted on the housing and has a display positioned to be viewable by a user, e.g., a firefighter. A controller processes the outputs generated by the sensors, and displays at a plurality of spaced-apart positions on the display a plurality of positional thermal indicators when the temperature in the respective thermal zone is elevated. The position of each positional thermal indicator corresponds to the thermal zone faced by the respective sensor.
Abstract:
A method and apparatus for blocking unwanted canine interactions during a canine deployment at a public-safety incident scene is provided herein. During operation all radios associated with a public-safety incident scene will be provided a notification of canine deployment. The radios will then generate a tone to deter or repel any approaching canine.
