Abstract: A tracking device for a track and rescue system that wirelessly couples to a control system via a first link established between a control system first type wireless communication interface coupled to the control system and a tracking device first type wireless communication interface included in the tracking device when the tracking device first type wireless communication interface is within range of the control system first type wireless communication interface. The tracking device determines that a first predetermine time period has been satisfied, and in response, determines location information for the tracking device using the positioning system. The tracking device sends, in response to the first predetermined time period being satisfied, an alive signal to the control system via the first link, and the alive signal includes the location information.

Abstract: A control system for a track and rescue system that wirelessly couples to a tracking device via a first link established between a tracking device first type wireless communication interface included on the tracking device and a control system first type wireless communication interface coupled to the control system when the tracking device first type wireless communication interface is within range of the control system first type wireless communication interface. The control system receives a first signal from the tracking device. The control system then determines whether the first signal from the tracking device indicates a rescue event and processes, in response to determining that the signal from the tracking device indicates a rescue event, instructions associated with the rescue event.

Abstract: A receiver device for a track and rescue system that monitors, via a receiver device first type wireless communication interface coupled to the receiver device, a physical environment for beacon signals provided by a tracking device first type wireless communication interface provided on the tracking device. The receiver device detects, via the receiver device first type wireless communication interface, a beacon signal and determines a direction from which the beacon signal is being transmitted. The receiver device performs a first action based on the direction from which the beacon signal is being transmitted. The receiver device monitors, via a receiver device second type wireless communication interface, the physical environment for alive signals from a tracking device second type wireless communication interface provided on the tracking device. The receiver device detects a first alive signal and, in response, performs a second action.

Abstract: A system for sensing motion and performing wireless communication, includes one or more antennas for transmitting and receiving wireless data communication signals and motion detection electromagnetic waves. One or more electrical switches switch among electrical paths activating frequency channel scanning, motion sensing, interference detection, and data communication. A motion sensor receiver receives motion detection electromagnetic waves. A transceiver generates both modulated RF signals for the wireless data communication and un-modulated RF signals for the motion detection. One or more processors process motion detection electromagnetic wave data and detected interference signal data as well as processing wireless communication data to and from the transceiver, controlling the one or more electrical switches, and providing commands to the transceiver.
