Abstract: A transmitter emits a pulsed radio signal and a digitally encoded radio signal near each exit of a protected premises. Monitored articles carry a receiver having a first circuit for receiving the pulsed signal, a power source, and a power switch for coupling the power source to a second circuit on detection of the pulsed signal. The second circuit receives the digitally encoded signal as multiple, serially-transmitted code bits. It also contains a clock for generating timing signals synchronized by the pulsed signal in order to distinguish a plurality of code bit intervals. A processor, an associated memory, and an address counter compare the digitally encoded signal with a stored bit pattern. On receiving an improper code bit, the processor causes the power switch to decouple the power source from the second circuit to conserve power. If the received signal matches the stored bit pattern, power is maintained to the second circuit. Alarm circuitry is triggered by overflow from the address counter. The address counter is reset each time the pulsed signal is received and thus produces no overflow, but when the article is removed from the protected premises, the address counter is allowed to overflow triggering the alarm circuit.

Abstract: A security dye pack disguised as a bundle of currency for deterring robberies includes a housing formed from a stack of currency bills sewn together and having a hollow chamber formed therein. A printed circuit board is disposed within the chamber for supporting electrical components which generate an actuating signal upon detecting removal of the security dye pack from the protected premises. A flexible pouch containing dye, tear gas, or other active chemicals, is secured at one end of the printed circuit board, and a squib extends into the pouch to ignite the chemical mixture when the actuating signal is generated. The flexible pouch is formed of a heat-resistant plastic film which is easily bendable. Foam cushions, protected by heat-resistant film, are disposed above and below the pouch and circuit board. Heat resistant plastic sheets extend about the foam cushions and are secured by an elastic thread to the housing to retain the components within the hollow chamber.

Abstract: A security dye pack disguised as a bundle of currency for deterring robberies includes a housing formed from a stack of currency bills sewn together and having a hallow chamber formed therein. A substrate disposed within the chamber has a flexible central region through which electrical conductors extend for making electrical interconnections between opposing ends of the substrate. Electrical components are mounted on both sides of the flexible central region to generate an actuating signal upon detecting removal of the security dye pack from the protected premises. Canisters containing dye or other active chemicals are secured at opposing ends of the substrate to emit dyed or other active chemicals in opposing directions when expended. The flexible central region of the substrate allows the security dye pack to be bent into a U-shape. Batteries are arranged in a side-by-side relationship in an elongated narrow case to facilitate bending of the security dye pack.
