Abstract

Abstract A device for connecting a conductor electrically to one out of a number of conductor by means of a photoconductive or semiconductive material and a light or electron beam. The particular output to be connected to the common input is chosen by selecting the direction or the spatial position of a light beam. The resistance of the connection depends on the intensity of the beam.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 147 words
An electronic switch comprising in combination a plurality of essentially linear conductors arranged in relatively close spaced and parallel relationship with one another one end of each of said conductors being in the same plane a layer of semiconducting material, one side of which is in contact with the said one end of said conductors, a conducting layer in contact with the other side of said semi-conducting layer, on the one hand, and connected to the said plurality of conductors on the other hand, a source of electrical energy connected to said conducting layer, and laser beam means focusible and movable onto the area of said conducting layer immediately spaced from any one of said conductors thereby establishing a galvanic connection between said conducting layer and the said conductor immediately spaced therefrom, the resistance of said connection being controlled by the intensity of said laser beam means.
Claim 2
Dependent Claim 147 words
An electronic switch comprising in combination a plurality of essentially linear conductors arranged in relatively close spaced and parallel relationship with one another one end of each of said conductors being in the same plane a layer of semiconducting material, one side of which is in contact with the said one end of said conductors, a conducting layer in contact with the other side of said semi-conducting layer, on the one hand, and connected to the said plurality of conductors on the other hand, a source of electrical energy connected to said conducting layer, and laser beam means focusible and movable onto the area of said conducting layer immediately spaced from any one of said conductors thereby establishing a galvanic connection between said conducting layer and the said conductor immediately spaced therefrom, the resistance of said connection being controlled by the intensity of said laser beam means.
Claim 3
Dependent Claim 20 words
The device according to claim 1 in which said conducting layer comprises a relatively thin light transparent sheet of metal.
Claim 4
Dependent Claim 48 words
The device according to claim 2 in which said sheet of metal is provided with ribs of relatively thick material having areas of relatively thin material therebetween, the areas of relatively thin material having light transmitting qualities and being situated over the said one ends of said conductors.
