Abstract
An omnidirectional remote control for use with electrically controllable devices. The remote control comprises a keypad input and a program selector for determining control signals to be transmitted by circuitry within the remote control. The remote control further comprises control circuitry which may be used to drive a plurality of transmitting diodes that are spaced around the perimeter of the remote control. The transmitting diodes are spaced so as to provide essentially omnidirectional transmission of control signals.
