Abstract: A movable barrier operator system is provided that includes a moving-barrier imminent motion notification apparatus, a motor, a controller, and communication circuitry configured to communicate with a remote control. In response to the communication circuitry receiving a communication from the remote control, the controller causes the motor to change the state of the movable barrier and additionally operate the moving-barrier imminent motion notification apparatus upon a determination of the remote control being beyond a physical proximity of a location associated with the movable barrier operator system. Upon a determination that the remote control is within the physical proximity, the controller refrains from operation of the moving-barrier imminent motion notification apparatus.

Abstract: A movable barrier operator includes a communication interface configured to receive commands that cause the motor to move the movable barrier. The movable barrier operator further includes a processing circuit configured to cause the motor to automatically move the movable barrier from a first open position toward a closed position and then from the closed position toward a second open position different from the first open position in response to receipt of an intermediate open command by the communication interface. The processing circuit can also cause the motor of the movable barrier operator to move the movable barrier toward the first open position in response to the processing circuit determining that the movable barrier had been obstructed while moving from the first open position toward the closed position.

Abstract: 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.

Abstract: Electronic systems are provided for secure actuation of a remote device such as a moveable barrier operator. The systems address the “man in the middle” problem of persons intercepting and duplicating radio frequency signals from a control device by introducing timing parameters into a bidirectional communication sequence between at least two devices.

Abstract: An obstacle detection system includes a first light emitter that emits a light signal and a first light detector configured to receive a portion of the light signal reflected back from an object. The obstacle detection system includes a second light emitter configured to emit a test signal toward the first light detector, and a second light detector configured to detect the light signal emitted by the first light emitter. The obstacle detection system includes a processor to determine, based on the light signal, whether an obstruction is detected and whether, by use of the second light emitter and the second light detector, the first light emitter and the first light detector are operable.

Abstract: A motion detector camera is configured to differentiate between an object or objects passing through the field of view of the camera and an object or objects approaching the sensor. In one example, motion is detected with a camera configured to identify and selectively filter specific directions of motion. The motion detector compares pixel changes, corresponding to the basic area or size of the object, from frame to frame, and detects the amount of increase in change or decrease in change. An increasing change in the area or size of an object indicates that an object is approaching, and a decreasing change in the area or size of an object indicates that an object that is receding.

Abstract: An apparatus for use with an auxiliary device for commanding a movable barrier operator, the apparatus having a first communication interface, a processor device, and a second communication interface. The first communication interface being configured to receive a status change request from the auxiliary device. The processor device runs a movable barrier controller application and is configured to generate a control signal for the movable barrier operator in response to receiving the status change request. The second communication interface is configured to send the control signal to the movable barrier operator through a network.
