Abstract

See full text

A door control apparatus and methods for controlling a door motion device for a hinged door and, optionally, illuminating a designated area on the floor. During the time the designated area is illuminated, a person can expect that the door will not close. The door control apparatus may include control circuitry, and a sensor, and optionally a light emitter and/or a sound emitter. The sensor detects a person proximate to the door and signals the control circuitry upon a detection event. The light emitter is also connected to the control circuitry. Upon a detection event, the control circuitry signals the light emitter to produce light and signals the door motion device to hold the door open. The light emitter directs light to form an image on the floor in the designated area. The light emitter may be, for example, a laser generator or a light emitting diode lamp.
