ABSTRACT:
A system and method for activating an electrical circuit for control purposes by bringing a portable electrical code generator or field modifying electrical circuit into a short wave energy field generated in the vicinity of a short wave receiver and causing energy of said field to be absorbed by said portable circuit and to trigger or energize the portable code generating circuit to cause it to generate a short wave code which is received by said short wave receiver. A code detector in the output of said short wave receiver detects the code received and activates the relay or switch which effects the control of an electrically activated device or circuit by supplying electrical energy thereto. The portable device may be supported by a finger ring, wristband, card or other means.
