CONTROL DEVICE AND ELECTRONIC DEVICE COMPRISING SAME
First Claim
1. Control device having a flat surface and comprising:
- at least one emitter-receiver pair comprising a radiation emitter to emit radiation and a receiver to receive the radiation emitted by the radiation emitter and reflected by a moving object located at a distance from said at least one emitter-receiver pair, the receiver is positioned within an emission field of the radiation emitter and provides an electrical signal representative of the radiation received from the radiation emitter;
a display configured to display at least one symbol identifying an action of said at least one emitter-receiver pair and opposite an intersection of an emission cone of the radiation emitter and an reception cone of the receiver, wherein the radiation emitter and the receiver are outside a display area of each symbol;
a controller configured to provide action control signals according to the electrical signal provided by the receiver;
wherein each emitter-receiver pair is associated with at least one symbol and at least one action control signal when the moving object is in front of the symbol identifying the action;
wherein at least one of the radiation emitter or the receiver is associated with at least one mask, whose transparent portion, for at least one wavelength used by the radiation emitter, is elongated in the direction of the receiver configured to detect a light of said at least one wavelength; and
wherein the surface of the control device is opaque to wavelengths used except in front of each receiver, each mask in front of the radiation emitter is at least partially transparent to the wavelengths.

Abstract
The control device comprises at least one emitter-receiver pair, a display and a controller. The emitter-receiver pair comprises a radiation emitter and a receiver for receiving radiation emitted by the emitter and reflected by a moving body located at a distance from the pair. The receiver is positioned within the emitter'"'"'s emission field and provides an electrical signal representative of the radiation received from the emitter. At least one symbol identifying an action, opposite an intersection of the emitter'"'"'s emission cone and the receiver'"'"'s reception cone, is displayed. The emitter and receiver are outside the display area of each symbol. The controller provides action control signal according to the electrical signal provided by the receiver. Each emitter-receiver pair is associated with at least one symbol and at least one action control signal when the moving body is in front of the symbol that identifies the action.
