Abstract:
Group-based emergency notifications and acknowledgments are managed via a radio controller. A request to transmit an emergency notification with acknowledgment to an identified target group of subscriber devices is received at the radio controller from a requesting device. The radio controller identifies one or more base stations actively serving subscriber devices associated with the identified target group and identifies, for each of the identified one or more base stations, active channels including one or more of a control channel associated with the base station and active voice or data channels associated with the base station. The radio controller causes an emergency notification outbound signaling packet (OSP), requesting individual acknowledgment and identifying the target group of subscriber devices, to be broadcast on the identified active channels at the identified one or more base stations. Acknowledgments are forwarded back to one of the requesting device and a dispatch console.
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.
