Abstract
A baby gate assembly which opens automatically only when detecting a designated person, by IR detection, RFID tagging or voice recognition. One or more IR detectors are mounted on a telescopic mast, enabling designation by height selection and the sensed signal compared with a datum or another IR facing in an opposite direct to provide signal operating reversible stepping motor to unlatch the gate. The control circuitry maintains the gate unlatched for sufficient time for the designated person to push open and walk through the gate in a hands free operation. A pedal release mechanism is also enabling unlatching during a power cut. The automatic and pedal unlatching mechanisms are linked for lost motion permitting independent operation.
