Abstract:
A non-electronic head-worn system for providing visual inertial head orientation information to a person is disclosed. The system comprises a head-worn unit that displays at least one orientation reference symbol to the person wearing the unit wherein the orientation reference symbol stays in a fixed visual position for the person when the person's head changes orientation. The system comprises an optical element located in the optical path between the user's eye and the orientation reference symbol, such as a lens, mirror, a prism, a beam splitter, a retro-reflector, or any other device or medium that can change the appearance or apparent location of an image. The system further comprises a pitch indicator that gives visual pitch information to the person and/or a roll indicator that gives visual roll information to the person. The pitch indicator and the roll indicator are responsive to a pendulum, a rolling element, or a fluid in a reservoir. The pitch element and the roll element do not use electricity or electronics.
Abstract:
A frame which has a wire extending across a rear of the frame is hung on a wall by an integral flexible spring member shaped to define a center mounting plate fastened to lie flat on the wall and a spring strap standing at right angles to the plate with a pair of arms each extending outwardly from the mounting plate along the wall to a respective side of the mounting plate. The arms receive and locate the wire extending along the arms and depending from ends of the arms to the sides of the frame. The arms can flex and the arms allow longitudinal movement of the wire along the arms to allow movement of the frame side to side relative to the mounting plate. A stiffening rod can be inserted onto the strap.

Abstract:
An integrated circuit includes a mechanical device for detection of spatial orientation and/or of change in orientation of the integrated circuit. The device is formed in the BEOL and includes an accommodation whose sides include metal portions formed within various metallization levels. A mobile metal component is accommodated within the accommodation. A monitor inside the accommodation defines a displacement area for the metal component and includes electrically conductive elements disposed at the periphery of the displacement area. The component is configured so as to, under the action of the gravity, come into contact with the two electrically conductive elements in response to a given spatial orientation of the integrated circuit. A detector is configured to detect an electrical link passing through the component and the electrically conductive elements.

Abstract:
To be able to measure the angular deviation simultaneously in two directions in space a magneto-sensitive sensor unit on the one hand (that can measure the magnetic flux density in at least two directions in space or orthogonal to each other) and a magnet on the other hand are moved relatively to each other, wherein one of both elements are provided in such a way that it aligns itself directly or indirectly according to the gravity. An optimal measuring result is achieved by guiding one of both elements on a defined, reproducible surface so that the center axis of this element is directed always to the center axis of the other element.
