Abstract:
A system and method of actuating a remote control access system in a motor vehicle non-invasively detects the occurrence of an event involving an actuation of at least one component of a motor vehicle. A control signal is transmitted to a remote control access system as a result of detecting the event.
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:
Ternary data as corresponds to a movable barrier operator is provided (21) and converted (22) into corresponding binary information. In a preferred approach this comprises converting each ternary trit into a corresponding binary pair. Pursuant to a preferred approach binary bits as correspond to, for example, fixed and/or non-fixed information (32 and 33) are provided (31) and then converted (34) into the aforementioned ternary data.
Abstract:
A recording of a macro is initiated. A first of a plurality of actions performable by the moveable barrier operator is selected and the first action is associated with the macro. At least a second of the plurality of actions available is selected at the moveable barrier operator and the second action is associated with the macro. A functional sequence of the first and second actions is recorded. The functional sequence specifies the order of performance of the first and second action. The recording of the macro is terminated. Subsequent to the terminating, actions recorded by the macro are performed at the moveable barrier operator in accordance with the functional sequence.
Abstract:
A movable barrier operator having an electrical motor responsive to control signals for moving the barrier, a controller to control the barrier movements, and two command apparatuses for generating command inputs, which command apparatuses are located remotely from each other. The first command apparatus is mounted in a location remote from the controller and easily accessible by the users, and the second command apparatus is located close proximity to the controller to be easily accessible by an installer at the time of service.
Abstract:
A system is disclosed including a transmitter and receiver for the communication of security codes which may be validated at the receiver to operate equipment. In one embodiment, the transmitter transmits a security code at two frequencies contemporaneously to the receiver which may receive both frequencies and resolve the security code therefrom. The receiver may lock onto one frequency when parts of a security code are detected to the exclusion of the other frequency. In another embodiment, the transmitter selectively transmits security codes at a default frequency which is selected because of a recorded count of prior apparent successful transmission.
Abstract:
One or more optical signals (wherein at least some of a plurality of optical signals are at different angles of travel with respect to one another and are directed towards an area comprising a movable barrier-controlled point of passage) create reflections when striking passageway boundaries as correspond to a given movable barrier. Obstacles in the pathway also give rise to reflections. By determining a time-of-flight for such reflections, one can detect a likely presence of an obstacle in such a pathway. Pursuant to one approach, such time-of-flight information can further provide information regarding a likely size of such an obstacle.
Abstract:
A system and method for sensing capacitance at the edge of a movable barrier and for detecting an obstruction includes positioning a conductive member within or about a holder. A sensed capacitance between the conductive member and ground. A controller is coupled to the sensor. The controller determines whether an obstruction exists within a path of the barrier by analyzing the sensed capacitance. The conductive member and holder move away from a physical reference as the physical reference is approached such that the sensed capacitance between the conductive member and the physical reference remains below a predetermined threshold.
Abstract:
A movable barrier operator having improved safety and energy efficiency features automatically detects line voltage frequency and uses that information to set a worklight shut-off time. The operator automatically detects the type of door (single panel or segmented) and uses that information to set a maximum speed of door travel. The operator moves the door with a linearly variable speed from start of travel to stop for smooth and quiet performance. The operator provides for full door closure by driving the door into the floor when the DOWN limit is reached and no auto-reverse condition has been detected. The operator provides for user selection of a minimum stop speed for easy starting and stopping of sticky or binding doors.
Abstract:
A wireless transmit-only apparatus (20) can be comprised of a controller (21) that selectively controls which of a plurality of resonant devices (24 and 25) are utilized to influence the transmission carrier frequency of a transmitter (26). In a preferred embodiment at least one of the resonant devices comprises a mechanically resonant device (24) such as a surface acoustic wave device, a crystal resonator, or a ceramic resonator. In a preferred embodiment, a user interface (22) includes a plurality of independently assertable inputs. The controller responds to assertion of one of this inputs by selecting a particular set of characterizing transmission parameters (as are stored, for example, in a memory (23) and using those characterizing transmission parameters to transmit a message using a transmission carrier frequency as corresponds to use of a co-selected resonant device.
