TL;DR: In this paper, an angular step generator has an input shaft whose angular position is to be determined absolutely, and at least two coding discs are provided in a plane, with axes of rotation (32a-32e) parallel and eccentric to the input shaft (12) axis.
Abstract: The step generator has an input shaft whose angular position is to be determined absolutely. An angular step coding discs, opto-electriconically scanned. Each code disc is driven by a preceding disc through stepping-down gears. At least two coding discs (24a-24e) are provided in a plane, with axes of rotation (32a-32e) parallel and eccentric to the input shaft (12) axis.

16 Sep 2005TL;DR: In this article, a part of optical members that compose the optical system is held to allow angular displacement relative to the housing, and the position of the part of the optical members is maintained in a predetermined state.
Abstract: An image stabilization apparatus comprises a housing accommodating an optical system in the interior thereof. A part of optical members that compose the optical system is held to allow angular displacement relative to the housing, and the position of the part of the optical members is maintained in a predetermined state. The part of the optical members is driven to restore the position angularly displaced. A driving amount is controlled based on information of the angular displacement. A mode for controlling the housing that is suitable for vibration applied to the housing is determined, and the mode is informed to a user.

TL;DR: In this paper, a magnetic sensor is arranged so that it can move in the direction of the taper of the plate thickness, and the output of the magnetic sensor indicates the displacement.
Abstract: A magnetic sensor having a simple structure and high accuracy for detecting a linear or angular displacement thereof. A magnetic plate with tapered thickness is magnetized in a direction perpendicular to its surface. A magnetic sensor is arranged so that it can move in the direction of the taper of the plate thickness. A drive mechanism for this magnetic sensor is movable with an object to be detected, and the output of the magnetic sensor indicates the displacement.

TL;DR: In this article, an angular displacement of a rotating object is measured with respect to a reference object by measuring an angular difference between the position of the turn sensor in relation to the moving object.
Abstract: An apparatus and method for sensing angular displacement of a rotating object. A reference object is provided that maintains an independent angular reference. An angular displacement of the rotating object may be measured with respect to the reference object. The apparatus may include a turn sensor for measuring directional changes in the heading of the object, an angular compensator, and a servomotor for maintaining the turn sensor in a same angular position. The object may be a vehicle such as a boat, car, train, airplane or any other vehicle. The turn sensor is coupled to the servomotor that may be attached to a platform of the vehicle. As the vehicle rotates, the heading of the vehicle changes. The servomotor rotates the turn sensor housing to keep the sensor at the same angular position. The heading may be determined by measuring an angular difference between the position of the turn sensor in relation to the moving object.
