A system and method for determining the presence of an individual at a particular spot within a location preferably based on the strength of signals received from beacons assigned to the particular spot by a software application (App) running on an electronic device of the individual. In one embodiment, certain presence calculations are performed by the App. In another embodiment, the App forwards information regarding the received beacon signals to an electronic identification and location tracking system and the presence calculations are performed by the system.

Provided is a system 10 for remote activation of an emergency radio beacon by a Search and Rescue (SAR) party, the system 10 comprising a controller 12 operatively arranged in signal communication with an emergency radio beacon 14, a positioning module 16 arranged in signal communication with the controller 12 and configured to operatively provide spatial positioning data to the controller 12, and a receiver 18 arranged in signal communication with the controller 12 and configured to operatively receive an activation signal 20. The controller 12 is configured to activate the beacon 14 upon receipt of the activation signal 20 and to provide the spatial positioning data of a potentially lost or distressed party to the beacon 14 for transmission along with an emergency signal 22.

A radar-enabled device that manages radar interference. In particular, the radar-enabled device detects a radar signal transmitted by a second radar-enabled device, transmits a notification of the detected radar signal, receives localization information associated with the second radar-enabled device, and sets a device location based on the received localization information. Additionally, the radar-enabled device may adjust a timing of radar signal transmissions to avoid subsequent detections of radar signals transmitted by the second radar-enabled device.
