摘要:
A switching device, for example a membrane switch, having an interconnect tail for electrically connecting the switching device to a circuit board. The tail has conductive traces formed thereon, which are in circuit with the conductive elements of the switching device. The conductive traces on the tail are raised from the plane of the tail thus making the traces the most prominent part of the tail. This structure assures electrical contact with the circuit board.

This invention provides a family of improvements to video security systems. In a first embodiment, a television set employed for normal television viewing is switched to be the monitor of the security system only upon the happening of a security violation event as sensed by a sensor. I one variation thereof, the switching capability is built into a dual-deck VCR along with the ability to reset the system to normal television watching by means of the remote control for the VCR. In another embodiment, the video cameras of the system are made easily adjustable and relocateable by the use of a bi-directional wireless transmission system linking the cameras to the base station and monitor. Video is sent from the cameras and control signals to adjust the field of view of the cameras are sent without the need for connecting cables. In another variation and improvement on the latter embodiment, a video camera is mounted on a mobile platform so as to be moveable and guidable to locations within a security monitoring area.

This is a method and associated apparatus for operating a control signal repeater system to receive infrared (IR) control signals at a first location and cause duplicate control signals to be input at a second location to an IR-controlled device containing an IR detector with connecting wires without creating a duplicate IR signal at the location of the controlled device. This is accomplished by directing voltage-inducing energy into the wires of the IR detector in the controlled device so that the signals are induced directly into the wiring to be amplified and used without the need for first generating an IR beam into the IR detector.
