    摘要: A mobile vehicular repeater detects the termination of a received transmission from a portable transceiver to be repeated and, in response to such detection, activates the up-link radio transmitter so as to send an acknowledgement signal to the message originating portable transceiver station signifying the probable successful conclusion of a repeating operation. Special techniques are utilized to prevent confusion between such an acknowledgement signal and similar prioritizing transmissions on the up-link frequency.

    摘要: Systems and methods for operating a security system. The methods comprise: monitoring an area for a presence of an individual or vehicle using wireless signals of a first type that are received by a first radio of the security system; operating the first radio as a wireless sensor for generating sensor data; determining whether the individual or vehicle is exhibiting an unusual behavior using the sensor data and pre-programmed or machine learned patterns of unusual behavior; changing an operating frequency of the first radio when a determination is made that the individual or vehicle is exhibiting unusual behavior; and communicating a wireless signal of a second type from the first radio when the individual or vehicle is exhibiting unusual behavior, where the second type is different than the first type.

    摘要: A security system tag. The security system tag includes a housing. The security system tag further includes an electronic article surveillance, EAS, element in which the EAS element is arranged to emit a detectable signal when introduced to an interrogation signal. The security system tag further includes a metal element in which the metal element is adapted to be heated. The security system tag further includes a first reversible adhesive proximate the metal element in which at least a portion of the first reversible adhesive de-bonds when thermally affected by the metal element when the metal element is heated.

    摘要: The invention is directed to a security element for the electronic surveillance of articles. This security element is detected by surveillance systems operating in different frequency ranges and it includes at least two materials of high permeability which, when excited by an external alternating magnetic field emit each a characteristic signal. The maximum signal components of the two materials lie in different frequency ranges and the signal components of the one material are negligibly ow in that particular frequency range in which the signal component of the other material is at a maximum level. The invention also relates to surveillance systems that incorporate these security elements.
