Abstract: A security device for preventing the theft of merchandise or other articles that provides for a closed loop system that is self-shunting without the need for removable shunt plugs. The preferred device comprises a plurality of jacks attached to a circuit board for receiving connector plug assemblies that are operatively connected to the articles through sensors. When the connector plug assemblies are not within a jack, a jack contact will engage a nail contact to close a circuit, thereby shunting the jack. Insertion of the connector plug assembly will deflect the jack contact away from the nail contact and create a second closed loop indicating that the jack is in use, and which will monitor and warn of any tampering with the sensor on the article.

Abstract: A security device for preventing theft of a hinged electronic product comprising a band that is inserted through the open area about the hinge of the product and a pair of anchor assemblies that are attached to the ends of the band. Alternatively, the security device may include a cable that extends about the hinge and is secured in an anchor assembly. A tether or cable attaches the security devices to an object to permit the hinged product to be moved over a limited distance. The security device also is connected to an alarm system so that removal or tampering with the band or cable activates the alarm. Filaments and contacts may also be used to detect the presence of the band within the second anchor assembly. An indicator may also provide notice when the security device is armed and/or tampered with.

Abstract: Sensors and methods for detecting attachment to a surface are disclosed. The sensors include a housing having an inner surface, an outer surface and a passage extending through the housing. An elongated member or fastener extends through the passage and protrudes from the outer surface of the housing to attach the sensor to a surface. First and second electrical contacts are disposed within the housing so that when the sensor is attached to the surface an electrical path is formed between the first and second electrical contacts.
