Abstract:
A vehicle wireless transmitter system includes a portable fob and a repeater mounted in the vehicle headliner. The portable fob includes user actuated buttons and code generation circuitry for a remote keyless entry system, garage door opener system, and home security system. When the user activates the garage door opener button on the portable fob from within the vehicle, the code generated by the portable fob is repeated by the repeater mounted in the vehicle headliner and retransmitted in a more powerful signal directed through the windshield. Thus, the portable fob insures that the code generation circuitry is removed from the vehicle with the user, while the repeater insures that the transmitted signal has enough power to provide satisfactory range.

Abstract:
A trainable transmitter is described that is capable of learning and replicating both AM and FM signals. The trainable transmitter also has the capacity to learn and replicate RF signals in both the 27 MHz to 40 MHz and the 250 MHz to 450 MHz frequency bands commonly used in European garage door openers. The trainable transmitter allows an individual to input an identification of the country in which the trainable transmitter will be operated such that the trainable transmitter may then transmit the learned signals at the maximum levels permitted for the identified county.
Abstract:
A method of indicating a degree of incoming threat to an electronically secured area comprising the steps of sensor sensing a degree of threat delivered to a secured area and generating an electric signal proportional to the degree of threat; analyzing the signal to determine if it is a low degree of threat or a high degree of threat; and producing either a first pulse representing low degree of threat or separately producing the first pulse and a second pulse representing a signal having both low degree of threat and high degree of threat.
Abstract:
A security system for monitoring a protected area and sounding an alarm including a plurality of sensors arranged about a protected area for sensing incoming threat, device for generating at least one pulse for each sensor activated by the incoming threat to the area, an alarm controller for receipt of the pulses and sounding of an alert, and a single wire connecting outputs of the sensors to the controller for transmitting the pulses generated by the plurality of sensors to the controller.
