Abstract

A cabled control/transmission device with a directional light projector of the present invention features one control/transmission device taking conducting wire as the signal media, as its light projector can project visible light on a display, functioned as the auxiliary assistance of presentation, the lighting beam, or a selection between the output light spot indication and lighting beam by means of adjusting the focal length.

Claims

1. A cabled control/transmission device with a directional light projector features one control/transmission device taking conducting wire as the signal media, as its light projector can project visible light on a display, functioned as the auxiliary assistance of presentation, the lighting beam, or a selection between the output light spot indication and lighting beam by means of adjusting the focal length is essentially comprised of:

supplies power from AC city power, or a main unit 110 to be described below adapted with the present invention for control and transmission, or a local DC source provide power to a man-machine operation interface 102, a dedicated circuit 103, and a light projector 105 to be described below;

the man-machine operation interface 102;

an optional items provided according to the requirements of the applied installations, including switch, press button, keyboard, display, or one or multiple conventional operation interface in the form of video, audio, optical or RF to operate the dedicate circuit 103 and the light projector 105 that generates visible light;

the dedicated circuit 103;

comprised of solid state electronic device, or dynamo-electric device, or integrated circuit and related software to provide functioning operation of the cabled control/transmission device adapted with a directional light projector;

a transmission conducting cable 104;

comprised of a conducting cable that is directly connected to the main unit 110 or through a plug and socket set and may be provided as follows as applicable;

(1) An optical fiber to transmit optical signals and a conductor to transmit electric power are linked either directly or respectively by means of optical and electric linking devices connecting to the main unit 110 subject to be controlled or transmission by the optical fiber and the electric conductor;

or

(2) An optical fiber to transmit optical signals is provided and directly linked to or linked by means of an optical linking device to the main unit 110 subject to be controlled or transmission by the optical fiber while the light projector 105 operates on its local DC source;

or

(3) A transmission electric conducting cable for conduction is provided and directly linked to or linked by means of an electric linking device to the main unit 110 subject to be controlled or transmission by the conductor to transmit electric signals and power; and

the light projector 105;

disposed to the casing of the control device and comprised of laser, diode, and associate drive circuit, or LED, bulb, or any other device to convert electric energy into visible light energy and associate drive circuit.

2. A cabled control/transmission device adapted with a directional light projector of claim 1, wherein the cabled control/transmission device adapted with a directional projector of the present invention is provided to control or transmit signals to the main unit 110 including that applied in information systems, communication systems, games, monitor systems, AV devices, computer, printer, recording devices, power toys, cabled control toys or any other home electric appliances, or any other electric appliance operating with =conducting cable as the control or transmission media for the cabled control/transmission device adapted with the directional light projector to control or transmit messages.
