Title: Obstacle detector unit for use by blind person - analyses light from beam emitted by unit and transforms this into audible signal
IPC: G09B21/00
Filed: 1976-04-08
Abstract: The unit enables a blind person to detect obstacles, analysing light reflected by a beam emitted by the unit. This information is transformed into an audible signal to provide a warning. A battery supplies power to a light emitting system through a switching circuit, the beam being focused through a lens into the required direction. An optical system receives the reflected light signal and focuses it onto photoelectric cells. These provide electrical impulses corresponding to the light image and these are fed into an electronic circuit. This gives a variable frequency audible signal, supplied to the user through an electro-acoustic unit.

IPC: E05F5/00
Filed: 1977-05-26
Abstract: A blocking member (1), a control member (2), a stop member (3), a control trestle (5), a resetting trestle (7) and a brake (8) are mounted on the fixed frame. The blocking member (1) and the control member (2) are each designed as a double-armed spring-loaded lever. A control cam (4) is formed on the control trestle (5) and a control cam (6) is formed on the resetting trestle (7). These control cams cause a pivoting movement of the blocking member (1) and of the control member (2) counter to the force of their resetting springs when they are displaced in the opposite direction to the arrow (19). The control cams (4, 6) are located respectively behind the blocking member (1) and the control member (2), as seen in the opening direction of the wing. Fastened to the wing is a double stop (9) which can also be formed from two separate stops. When the wing is being closed in the direction of the arrow (19), the double stop (9) runs through unimpeded under the resetting trestle (7) and the control member (2). Finally, it runs onto the stop face of the blocking member (1) and displaces the latter, until the end of the shorter lever arm of the blocking member (1) comes up against the stop member (3). The stopping of the wing is caused by the brake (8) which is actuated by the double stop (9), the blocking member (1) being interposed. By means of this device, the wing, which is displaced vigorously into the closing position, is braked shortly before the closing position, in order thereby to avoid the risk of injury.
