Abstract
For remotely operating security barriers such as gates, garage doors and the like by manipulating multiple pre-existing equipment controls of a motor vehicle simultaneously or successively, a vehicle-integrated access control device is described having an access control signal transmitter, an optional voltage regulator, and means for causing the operation of the transmitter to depend on the actuation in concert of several vehicle controls such as, for example, the simultaneous or rapidly successive actuation of the left and right turn signals of a motorcycle. A logical AND device and, alternatively, a pair of transistor switches are disclosed for establishing the dependency. One or more optional relays are disclosed for establishing the dependency. A latching circuit is described for establishing the dependency upon successive actuation of first and second circuits. Wires connected to the vehicle are disclosed for establishing input from the vehicle controls, power from the vehicle electrical system, and electrical grounding. A voltage reducing circuit, optionally including a voltage divider or a Zener diode, is disclosed for accommodating a lower voltage transmitter to a higher voltage vehicle electrical system.
