Abstract: The invention is directed to a system for detecting the presence or absence of a blocker to an air code flow. The system comprises an active air code generator, a sensor element through which an air code generated by the active air code generator travels, and an air code detector, which detects the air code, wherein if the detection of air code by the air code detector is interrupted, it signals the presence or absence of a blocker of the air code.

Abstract: An anti-crime security system which provides an entrance and an exit to an establishment, wherein the entrance and exit define an enclosed area, provides sensors to monitor ingress and egress through the enclosed area, and monitors activity in the enclosed area and controls access to the establishment based on the ingress, egress, and activity monitored by the sensors.

Abstract: A power distribution and anti-theft alarm system for monitoring a plurality of electronic equipment utilizes existing front-end noise suppressor capacitors to provide a return path along the power supply lines of an injected RF current back to the system monitoring. Accordingly, removal or cutting of the power supply cords to the various electronic equipment can be monitored to provide a theft deterrent. Corresponding LEDs are utilized to provide status of the various channels coupled to the power distribution and anti-theft alarm system. Accordingly, power on/off, alarm on/off and electronic equipment status is indicated.
