Abstract: A hinge position sensor comprises first and second members connected together to provide a hinge, and an optical fiber or wave-guide connected between the first and second members to provide a communication link between the first and second members. A laser or LED is coupled to the optical fiber or wave-guide to transmit optical signals between the first and second members and the optical signal is received by a photo-detector. The optical fiber or wave-guide is physically distorted by actuation of the hinge such that light escapes from the optical fiber or wave-guide. The optical power level received by the photo-detector is used to determine the position of the hinge.

Abstract: The specification and drawings present a new method and apparatus for a rotary hinge for transmitting an optical signal (e.g., comprising data) bi-directionally or uni-directionally from one part to another in an electronic device, wherein these parts can rotate relative to each other using the rotary hinge. The optical signal can be transferred from one side to the other side of the hinge independently from light transmitted in the opposite direction. A sending guiding element (e.g., an optical fiber or a light guide) can rotate around a common rotation axis permanently attached to the side sending the optical signal and the emitted optical beam is directed towards the common rotation axis. The receiving guiding element, which collects the optical beam, is concentrically in the center (coinciding with the common rotation axis) of the receiving side and permanently attached to it.

Abstract: An electrically controlled light modulator device comprises at least one cell, where two deformable dielectric layers meet at an interface, at least one of said layers consisting of viscoelastic relief forming gel. A first support electrode structure and a second signal electrode structures are arranged on separate sides of the dielectric layers in order to create an electric field passing through said layers and in order to create surface reliefs on the viscoelastic gel layer. According to the invention, a third enhancement electrode structure is arranged in the proximity of the first signal electrode structure. Applying enhancement signal voltage between the enhancement electrode structure and the signal electrode structure concentrates locally the electric field passing through the two deformable dielectric layers and therefore enhances the amplitude of the deformation of the viscoelastic gel layer.

Abstract: An optical hinge and an optical hinge apparatus for providing an optical link between a first circuit board and a second circuit board. The optical hinge is made of two optical components, separated by an air gap, to allow a light beam to transmit from one optical component to another via the air gap. The optical components can be rotated relative to each other along a rotation axis. Each of the optical components is optically coupled to an opto-electronic device on a circuit board. Preferably, the light beam is transmitted through the air gap along an optical path which is substantially parallel to or coincident with the rotation axis. The light beam can be used to carry optical signals in order to convey communication data from one circuit board to another. The optical signals can be transmitted in infrared frequencies or visible frequencies.
