Patent ID: 8488972

Claim:
A directional control/transmission system arranged to control or communicate with a device to be controlled or communicated with, said device having a receiving unit by using infrared or ultrasonic waves as a carrier, said directional control/transmission system comprising: an infrared or ultrasonic transmission unit for converting electrical signals into said infrared or ultrasonic waves and for transmitting said infrared or ultrasonic waves; a dedicated circuit for operating said transmission unit; a power source; and a directional light projector, wherein the light projector is connected to said power source and outputs a visible light beam, wherein the directional light projector further includes an arrangement for diffusing said visible light beam to serve as a lighting beam, and wherein said visible light beam is arranged to be transmitted in a same direction as the infrared or ultrasonic waves to facilitate aiming of the infrared or ultrasonic waves at the said receiving unit of said device to be controlled or communicated with, and wherein said visible light beam is adjustable to be aimed in a different direction than the infrared or ultrasonic waves so as to illuminate a display while the infrared or ultrasonic waves are aimed at said receiving unit.
