Abstract:
A plurality of conductive members is disposed on an edge of a moveable barrier. The edge has a width and each of the conductive members is disposed along a portion of the width. A controller is coupled to each of the plurality of conductive members and is programmed to determine whether an obstruction exists within a path of movement of the barrier by analyzing a first capacitance sensed by a first of the plurality of conductive members and ground and a second capacitance sensed by a second of the plurality of conductive members and ground.
Abstract:
A moveable barrier operator actuates an actuator thereby causing a message to be formed. The message indicates that the user at the moveable barrier operator requires assistance. A communication channel is established between the moveable barrier operator and an assistance center. The message is transmitted to the assistance center over the communication channel. An assistance action is performed to provide assistance to the user at the moveable barrier operator.
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 barrier movement operator system having a receiver for receiving, learning and responding to transmitted rolling code type access codes; at least one trained transmitter for operating the system by transmitting a rolling code type access code to the receiver; at least one learning transmitter for learning the rolling code type access code from said trained transmitter in order to operate the system; a controller for evaluating the relationship between the learning transmitter rolling type access code and the trained transmitter rolling type access code; and a device for providing a barrier movement in response to access codes received by the receiver. The barrier movement operator provides a method of learning valid security codes by a security code receiver comprising the steps of receiving a first security code, then within a predetermined period of time receiving a second security code, having a predetermined relationship to the first security code; and storing a representation of the second security code as a valid security code.
Abstract:
A wireless transmit-only apparatus (20) has a controller (21) that responds to a user interface 25 by correlating specific user input with a corresponding characterizing transmission parameter(s) as is stored in a memory (35) and by selecting a corresponding resonant device (31 and 32). The latter devices serve to drive the PLL control input of a phase locked loop (23) to thereby influence the transmission carrier frequency of a wireless transmitter (22). In a preferred embodiment, at least one of the resonant devices comprises a mechanically resonant device such as a surface acoustic wave device, a crystal resonator, or a ceramic resonator.
Abstract:
When a movable barrier operator detects (101) a predetermined state with respect to a remote transmitter learning mode, the movable barrier operator can respond by temporarily requiring (103) at least a first programmer protection duration of time to pass before permitting the movable barrier operator to respond to a remote transmitter-sourced barrier movement control signal. By one approach this first programmer protection duration of time is longer than a loss-of-signal detection duration as characterizes the movable barrier operator.
Abstract:
An encrypted rolling code (11), a plurality of differing data bit order patterns (13), and a plurality of differing data inversion patterns 14) are provided. One then selects (15) a particular one of each of these patterns and uses those selected patterns as transmission characteristics when transmitting (16) at least part of the encrypted rolling code.
Abstract:
A keypad transmitter for mounting outside a controlled area which may respond to the voice or other biometric indicia of users by transmitting validatable codes to a controller of a barrier movement system. The keypad may be used to send a validatable code or it may be used in a learning operation of the voice responsive portion. The voice responsive portion includes speaker dependent voice analysis for some functions and speaker independent voice analysis for other functions.
Abstract:
A secure communication link (24) is provided between a movable barrier operator (23) and a peripheral alarm system (20). Information conveyed via this link is used by one, the other, or both such elements to further inform or direct their respective actions.
Abstract:
A power ventilation system comprising an exhaust fan, a power supply, and a control system is provided for ventilation of a garage. The ventilation system may be controlled by a moveable barrier, interfaced to a weather seal of the garage door, or configured to allow power ventilation of the garage when the garage door is closed.
