US Patent 10163337 Trainable transceiver with hands free image based operation

A method for automatically transmitting an activation signal from a trainable transceiver to a remote electronic system, includes receiving, at a control circuit of the trainable transceiver, image data from an image data source; determining, using the control circuit, if the received image data matches one or more reference images stored in memory and associated with the remote electronic system; and determining, in response to a match between the received image data and the one or more reference images, if the trainable transceiver is approaching the remote electronic system. The method includes, in response to determining that the trainable transceiver is approaching the remote electronic system, formatting an activation signal to control the remote electronic system and transmitting, using a transceiver circuit, the activation signal formatted to control the remote electronic system.
