An encrypted rolling code, a plurality of differing data bit order patterns, and a plurality of differing data inversion patterns are provided. Based on the encrypted rolling code, patterns are selected from one or more of the plurality of differing data bit order patterns and the plurality of differing data inversion patterns. At least a part of the encrypted rolling code is transmitted to a movable barrier operator using the selected patterns as transmission characteristics.

Method and apparatus to facilitate transmission of an encrypted rolling code

An encrypted rolling code, a plurality of differing data bit order patterns, and a plurality of differing data inversion patterns are provided. One then selects a particular one of each of these patterns and uses those selected patterns as transmission characteristics when transmitting at least part of the encrypted rolling code.

Binary data relating to a movable barrier operator is converted to ternary data. The ternary data is converted into corresponding binary information in a way not mirroring the first conversion method. In one approach, this second conversion converts each ternary trit into a corresponding binary pair. Initial binary bits correspond to, for example, fixed and/or non-fixed information.

Transmission of data including conversion of ternary data to binary data

An encrypted rolling code (), a plurality of differing data bit order patterns (), and a plurality of differing data inversion patterns) are provided. One then selects () a particular one of each of these patterns and uses those selected patterns as transmission characteristics when transmitting () at least part of the encrypted rolling code.

An automated movable barrier control system component () as comprises a part of a movable barrier control system () has an audible speech output device () operably coupled thereto. These elements can share a common housing (). The audible speech output device () can audiblize one or more items of stored speech content relating to one or more aspects of the component itself, other components within the system, and/or the system itself.

Movable barrier control system component with audible speech output apparatus and method

A movable barrier operator system operational component includes an integral display comprising at least one of a numeric display, an alphanumeric display, and a graphics display. The display can comprise an active display or an active interactive display and can further operate in conjunction with adjacent user-input interface opportunities. So configured, numerous user interface events can be highly leveraged to contribute to ease of installation and ease and reliability of use.

Movable barrier operator system display method and apparatus

Operating parameters as were previously learned by a first movable barrier operator () are transferred to a second movable barrier operator () such as, for example, to a replacement movable barrier operator. Pursuant to a preferred approach, such information transfer occurs via a receiver interface () that ordinarily serves to couple the movable barrier operator () to one or more remote user interfaces (). Pursuant to one approach this transfer occurs during a learning mode of operation.

Movable barrier operator operating parameter transfer method and apparatus

A movable barrier operator having a motor controller () and motor () that control selective movement of a movable barrier () also has an obstacle detector () that utilizes an automatically determined excess force threshold value to permit reliable detection of an obstacle under a wide variety of operational circumstances, including changing physical circumstances, aging components, temperature variations, and motor runtime. In a preferred embodiment, a characteristic force value for the system is frequently updated as a function of actual measured force requirements (and further compensated, pursuant to various embodiments, with respect to other conditions such as temperature and motor runtime). This characteristic force value is then utilized to determine the excess force threshold value.

Movable barrier operator auto-force setting method and apparatus

Ternary data as corresponds to a movable barrier operator is provided () and converted () 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 (and) are provided () and then converted () into the aforementioned ternary data.

Method and apparatus to facilitate transmission of ternary movable barrier operator information

In a movable object system () that makes use of both a maintained count () that corresponds to movement of a given object and passpoint events () as generated by a corresponding passpoint signal generator (), count zones (A,B) can be defined for at least one of the passpoint events. Such count zones can be used to aid in determining when significant recalibration of the passpoint event/count value relationships should be undertaken. In a preferred embodiment, such count zones include no more than a single passpoint event.

Self-healing passpoint-facilitated method and apparatus

A barrier operator comprises a first measuring apparatus for measuring a current used by a direct current (dc) motor to move a barrier and a second measuring apparatus for measuring a generated voltage of the dc motor. A controller is coupled to the first measuring apparatus and the second measuring apparatus. The controller is programmed to calculate a torque of the dc motor by using the current and to determine when an obstruction exists in the path of the barrier based upon the calculated torque.

System and method for determining barrier motor parameters without using sensors

A method is provided for use with a movable barrier operator that has no user-initiable dedicated learning mode of operation. At least one parameter is monitored that corresponds to force as applied to a movable barrier to selectively cause the movable barrier to move between at least a first position and a second position. An excess force threshold value is automatically changed in response to the monitored at least one parameter to provide an updated excess force threshold value. Both the updated excess force threshold value and the monitored at least one parameter are used to determine when excess force is being applied to the movable barrier via the movable barrier operator. A predetermined action is taken when excess force is being applied to the movable barrier via the movable barrier operator.

A programmable transmitter that verbally questions a user with audible questions to determine a type of a transmitter being emulated. The transmitter receives indicia of the type the transmitter and determines the type of the necessary transmission parameters based upon the received indicia. For operator system types that utilize DIP switch programming, the transmitter provides a voice menu of possible DIP switch settings and the user responds to the voice menu. The transmitter receives responses from the user via buttons and/or the user's voice commands.
