Abstract
Abstract Equipment to test psychologically drivers of all kinds of motor vehicles, and in particular, to test stereoscopic vision. The testing of stereoscopic vision consists in checking up the competence of spatial perception, necessary for distance evaluation. The equipment consists of two main parts: a measuring and recording device, and a control desk of the tested person. The test consists of aligning two measuring rods with the third one, which is in the middle, and is immobilized. The tested person looks through a slot in the wall of the control desk, and operates an aligning mechanism. The results of the test are automatically recorded on the recording plate of the equipment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
Apparatus for testing stereoscopic vision which comprises: a casing having at least two longitudinal parallel side-by-side paths, a mechanism mounted in said casing to be movable parallel to said paths and to be selectively positioned at various locations therein, a first measuring means affixed to said mechanism which is located in one of said paths, a second measuring means movably mounted in said mechanism which is in the other of said paths, driving means mounted in said mechanism for moving said second measuring means in either direction relative thereto and connective means for selectively connecting said second measuring means to said driving means, a control desk provided with means for directing movement of said second measuring means in either direction along said other path by actuating said connective means, said control desk being selectively fixed relative to said casing whereby a person being tested who is located at said control desk simultaneously views both said measuring means and controls the movement of said second measuring means to align same with said first measuring means by selectively connecting said second measuring means to said driving means.
Claim 2
Dependent Claim
185 words
Apparatus for testing stereoscopic vision which comprises: a casing having at least two longitudinal parallel side-by-side paths, a mechanism mounted in said casing to be movable parallel to said paths and to be selectively positioned at various locations therein, a first measuring means affixed to said mechanism which is located in one of said paths, a second measuring means movably mounted in said mechanism which is in the other of said paths, driving means mounted in said mechanism for moving said second measuring means in either direction relative thereto and connective means for selectively connecting said second measuring means to said driving means, a control desk provided with means for directing movement of said second measuring means in either direction along said other path by actuating said connective means, said control desk being selectively fixed relative to said casing whereby a person being tested who is located at said control desk simultaneously views both said measuring means and controls the movement of said second measuring means to align same with said first measuring means by selectively connecting said second measuring means to said driving means.
Claim 3
Dependent Claim
20 words
Apparatus for testing stereoscopic vision in accordance with claim 1 wherein said driving means comprises a continuously moving endless member.
Claim 4
Dependent Claim
77 words
Apparatus for testing stereoscopic vision in accordance with claim 2 wherein said mechanism includes a plurality of electrically conductively segments, electrical control means interconnecting said second measuring means and at least one of said segments the position of which is dependent on its distance relative to said first measuring means, circuit means between said interconnection and a registration means provided to register the relative distance longitudinally along said paths between said first and said second measuring means.
