Abstract
A method for teaching a switching circuit is provided. The method includes presenting a target within a sensing range of a sensor of the switching circuit for a pre-determined duration and acquiring an identification code of the target via the sensor. The method also includes storing the acquired identification code for operating the switching circuit and locking the switching circuit against learning identification codes of any other target prior to reaching an allowed number of reteaching attempts.

9. A method for teaching a switching circuit, comprising:
-
acquiring an identification code of a target via a sensor of the switching circuit when the target is presented within a sensing range of the sensor for a pre-determined duration; storing the acquired identification code, wherein the acquired identification code is configured to be used to operate the switching circuit at least one time; and preventing the switching circuit from using any other identification code that corresponds to any other target presented within the sensing range of the sensor to operate the switching circuit. - View Dependent Claims (10, 11, 12, 13, 14)

15. A reteachable switching circuit, comprising:
-
a non-contact sensor; a target movable into and out of a sensing range of the sensor; and a processor configured to reprogram the switching circuit for operation of the switching circuit based upon an identification code of the target sensed by the sensor and to prevent the switching circuit from learning any other identification code of any other target sensed by the sensor. - View Dependent Claims (16, 17, 18, 19, 20)
