Abstract: A process for dynamic vehicular threat detection perimeter modification for an exited vehicular occupant includes prior to detecting a vehicular occupant exiting the vehicle, establishing a first sized vehicular geofence surrounding the vehicle as a function of one or more stored vehicular perimeter distances. The first sized vehicular geofence is monitored for a first breach via one of a 360 degree vehicular light imaging and radio wave distancing system. In response to detecting that the vehicular occupant previously inside the vehicle has exited the vehicle, the one or more stored vehicular perimeter distances is modified as a function of a detected location of the exited vehicular occupant to establish a second sized vehicular geofence surrounding the vehicle different than the first sized vehicular geofence. The second sized vehicular geofence is monitored for a second breach via one of the 360 degree vehicular light imaging and radio wave distancing system

Abstract: A security sensor system is provided which allows the stopping of the device due to the end of a battery life to be postponed by suppressing battery power consumption, which is caused due to an object detection operation of the security sensor system, after a low battery state is detected. The security sensor system is powered by a battery. When a low battery detector detects a reduction in the voltage of the battery, an object detection operation of the security sensor system is switched from a normal mode to a suppression mode. Consumption of the battery in the suppression mode is suppressed.

Abstract: Systems and methods of using active infrared (AIR) sensors to map a room of a home or building and determine whether an external portal (e.g., window and/or door) of the room is open or closed are provided. In particular, the systems and methods include outputting infrared (IR) light from an IR light source of an active infrared (AIR) sensor, receiving reflected IR light with a light sensor, and determining, with a processor coupled to the light sensor, whether a window of a room is open according to the received reflected IR light.

Abstract: Systems (100) and methods (1800) for determining where an object or person is located in an EAS detection zone. The methods involve: simultaneously emitting a first signal from a first emitter and a second signal from a second emitter; concurrently detecting the first and second signals during a first period of time by each of a first detector and a second detector; and determining where the object or person is within the EAS detection zone based on a pattern of a signal output from at least one of the first and second detectors which reflects that at least one of the first and second signals is blocked by the object or person during at least one of a second period of time and a third period of time in which the object or person is traveling through the EAS detection zone.

Abstract: An array of paired V-band sensors is provided to act as a virtual fence to detect human intrusion. Each sensor includes a rotating circuit board that includes an antenna array. The sensor pivots the circuit board with regard to a weight base to align with an opposing sensor. By alternatively transmitting and receiving with regard to the opposing sensor, a V-band bistatic radar system is enabled that detects human intrusion between the opposing sensors.
