    摘要： A rolling code transmitter is useful in a security system for providing secure encrypted RF transmission comprising an interleaved trinary bit fixed code and rolling code. A receiver demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and rolling codes with stored codes and determining that the signal has emanated from an authorized transmitter, a signal is generated to actuate an electric motor to open or close a movable barrier.

    摘要： A barrier movement system which is useful in provided barrier movement in environments where a first barrier such as a community gate is commonly controlled by a plurality of different actuators (transmitters) which actuators separately control other barriers such as household garage doors. The controller of the commonly controlled gate receives and contemporaneously analyzes codes in accordance with a plurality of different code format standards and at the same time analyzes the received code to determine which format is actually being received. In an embodiment only a fixed code portion of a rolling code sequence is used for actuation at the commonly controlled barrier.

    摘要： A rolling coda transmitter is useful in a security system for providing secure encrypted RF transmission comprising an interleaved trinary bit fixed code and rolling cede. A receiver demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and roiling codes with stored codes and determining that the signal has emanated from an authorized transmitter, a signal is generated to actuate an electric motor to open or close a movable barrier.
