Movable barrier e.g. garage door, monitoring apparatus, has receiver box coupled to movable barrier operator to combine status image of movable barrier with display signal and to send combined signal to viewing monitor

摘要

The apparatus has a movable barrier operator (104) for controlling movement of a movable barrier (102). A barrier status sensor generates status signal representing status of the barrier. A receiver box (108) coupled to the barrier operator combines a status image with a display signal sent from a signal source (106). The receiver box sends the combined signal to a viewing monitor (110). An independent claim is also included for a method of monitoring a movable barrier.
