Abstract: A selective intrusion detection system includes a Doppler transceiver configured and adapted to receive Doppler return signals indicative of moving targets present in a surveillance space. A processor is operatively connected to the Doppler transceiver to convert Doppler return signals into spectrograms and to determine whether any given spectrogram is indicative of presence of a human or another moving target, like a domestic pet. An alarm is operatively connected to the processor, wherein the processor and alarm are configured to provide an alert in the event the processor determines any given spectrogram is indicative of a human, and to forego providing an alert in the event the processor determines any given spectrogram is indicative of another moving target only.

Abstract: A system includes a transceiver for receiving a wake up signal from a wireless communication device. A processor is operatively connected to the transceiver and to a memory. The memory includes instructions recorded thereon that, when read by the processor, cause the processor to transition from a sleep mode to an active mode and power up the transceiver upon validation of the wake up signal.

Abstract: A power management circuit decreases power consumption in an electronic door lock. The power management circuit includes an ON/OFF circuit, a load switch circuit and a electronic door lock circuit. The ON/OFF circuit generates an initial enable signal in response to a detected keycard that places the load switch circuit in an enabled state. When enabled, the load switch circuit provides dc power to the electronic door lock circuit that allows the electronic door lock circuit to receive identification input from the detected keycard and determine whether an output should be generated to actuate the door lock mechanism. Having completed the keycard detection operation, the electronic door lock circuit generates a self turn-off signal that is provided as feedback to the ON/OFF circuit to disable the load switch circuit.
