Abstract: A device has a distance sensor and a transmitter. The distance sensor, attached to a barrier, measures an opening formed by the barrier. The transmitter transmits a control signal to a barrier controller. The barrier controller controls a movement of the barrier based on the control signal. The device receives a requested size of the opening. The device transmits, to the barrier controller, a first control signal that instructs the barrier controller to move the barrier and a second control signal that instructs the barrier controller to stop the movement of the barrier after an elapsed time has expired. The device measures a final size of the opening and adjusts the elapsed time based on the final size of the opening and the requested size of the opening.

Abstract: A method and apparatus for searching a program guide comprising program information for a plurality of different program sources. The program information includes the titles of the programs, the channel on which each program is to be shown, and the time at which each program is to be shown. The viewer first enters the title of a desired program. The program guide is then reviewed so as to identify each occurrence of the title of the desired program. If the desired program is contained in the guide, the time and channel associated with each identified occurrence of the program is displayed.
