摘要： In one aspect of the present disclosure, a movable barrier operator system is provided that includes a motor configured to turn a drum to pay out a cable from the drum and permit a door connected to the cable to move from an open position toward a closed position. The system includes a memory configured to store an expected variable of the door, and a sensor configured to detect movement of the door. The system further includes a processor circuit operatively coupled to the motor, the memory, and the sensor. The processor circuit is configured to: use the sensor to estimate an actual variable of the door; determine whether the actual variable is acceptable based at least in part on the expected variable and the processor circuit causing the motor to turn the drum; and change operation of the movable barrier upon the actual variable of the movable barrier being unacceptable.

摘要： In one aspect, a universal receiver is provided for being operably coupled to a movable barrier operator. The universal receiver includes at least one radio antenna adapted to receive signals transmitted at different frequencies and a controller operably coupled to the at least one radio antenna. The controller is adapted to determine a code of a signal received by the at least one radio antenna at any one of the different frequencies. The controller being further adapted to learn the code in response to a user-independent learning condition being met.
