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 locking device employs improved lock management techniques based on time delay polices that use a random period of time. The locking device receives a first credential of a custodian, validates the first credential and determines a random period of time based upon a time-delay policy when the first credential is validated. The locking device executes a lock release protocol upon expiration of the random period of time.

Abstract: An antenna (10) is provided including a generally rectangular ground element (20) having a first end and a second end. The ground element (20) includes at least one hole (30, 30?) for mounting the antenna to a support structure. A generally rectangular radiating element (12) having a third end and a fourth end if parallel to the ground element (20) and separated from the ground element (20) by a space. A bend connects the first end of the ground element (20) to the third end of the radiating element (12). A coaxial cable includes a center conductor coupled to the radiating element (12) at a feed point and an outer conductor coupled to the ground element (20).
