Abstract:
Apparatus (10) for controlling access to a secure region has an audio transducer. A DTMF decoder is connected to the audio transducer (24). A processor (26) is connected to the DTMF decoder to receive DTMF signals. A memory is connected to the processor (26) storing a code. The processor (26) compares the stored code to the signal from the DTMF decoder and generates an access enable signal in response thereto. A baseband signal output system for connection to a wall control of a garage door operator and for providing a base signal in response to the access enable signal. A radio frequency transmitter (14) provides a radio frequency signal to a radio frequency receiver of the garage door operator in response to the access signal.
Abstract:
Remote control signaling may be conveyed using a spread spectrum link and/or a non-spread spectrum link. Enabling link interfaces (such as corresponding transmitters, receivers, or transceivers) to support this flexibility are provided in a shared housing and couple as appropriate to a remote control signal platform. A corresponding apparatus may comprise a housing having disposed therein a first radio frequency transmitter such as a , spread spectrum transmitter and a second radio frequency transmitter such as a non-spread spectrum transmitter. This housing can further contain a remote control signal controller that operably couples to at least one of the first and second radio frequency transmitters. As another example, a corresponding apparatus may comprise a housing having disposed therein a first radio frequency receiver comprising a spread spectrum receiver and a second radio frequency receiver comprising a non-spread spectrum receiver.
Abstract:
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 (202) demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and rolling codes with stored codes (220) and determining that the signal has emanated from an authorized transmitter, a signal is generated to actuate an electric motor (234) to open or close a movable barrier.
Abstract:
A system includes a translator device that is configured to receive, using a pre-programmed native mode of operation, a first barrier actuation code transmitted by a transmitter according to a first code format. The translator device then analyzes the first barrier actuation code and verifies that it is a valid code. When a valid code, the translator device saves the information contained in the code, and creates a second barrier actuation code at least in part from information contained in the first actuation code and transmits the second barrier actuation code according to the second code format, which is different from the first code format. A barrier operator is coupled to the translator device and a barrier. The barrier operator has a receiver apparatus and the receiver apparatus receives the second barrier actuation code. The barrier operator determines whether the second barrier actuation code is valid, and when the barrier actuation code is determined to be valid, actuates the barrier.
Abstract:
A moveable barrier operator that is used as a repeater includes a receiver device having an input, a transmitter device having an output, an apparatus responsive to predetermined signals received by the receiver for controlling the position of a barrier; and a controller. The controller is coupled to the receiver device and the transmitter device and controller is programmed to receive a signal from a signaling actuation device at the input of the receiver device. The controller is programmed to responsively re-transmit the signal to at least one other moveable barrier operator from the output of the transmitter device when indicated by the signal.
Abstract:
An access control mechanism such as a movable barrier operator (70) has a first time window unit (72) that is responsive to one or more triggers (71) (such as a delayed-closure button). An event detector (73) then monitors for one or more events of interest during a corresponding first time window. For example, the event detector can monitor for evidence that a vehicle is moving towards a garage exit or has effected an exit from the garage. A second time window unit (74) responsive at least to the event detector and optionally as well to the first time window unit then responds with a second time window. Upon conclusion of the second time window, a movable barrier closer (75) initiates movement of the corresponding movable barrier towards a closed position (or other position of interest).

Abstract:
An entry control system and method for permitting authorized users to access a controlled area by moving a barrier comprises a specific action button and an entry request device for accepting a user data input. A controller is operably coupled to the entry request device and the specific action button and having an output. The transmitter receives the user data input and an indication of a position of the barrier and determines based at least in part upon the user data input and the indication of the position of the barrier whether a first control signal should be generated at the output, the controller also receiving an indication of an actuation of the specific action button and selectively generating a second control signal at the output based at least in part upon the indication of the position of the barrier.
