The details of the correction processing are determined according to correction information. The indicator value generation unit generates, on the basis of the plurality of detection signals, an indicator value having a correspondence with the error of the detected angle value. The correction information determination unit generates an estimated indicator value using a function that takes one or more values each having a correspondence with the correction information as one or more variables, and determines the correction information by adaptive signal processing so as to reduce the difference between the indicator value and the estimated indicator value.Type: ApplicationFiled: November 21, 2017Publication date: June 21, 2018Applicant: TDK CORPORATIONInventor: Shinichirou Mochizuki

Publication number: 20180172483Abstract: Optical encoding systems include a generalized cylindrical code scale having one or more regions with different light reflective properties. In an example process, a code scale can be created by coating an elongated generalized cylinder with one or more different layers of materials having different light reflective properties. Portions of these layers can be removed selectively in order to expose a particular overlying material and create a particular pattern of features having different optical characteristics (e.g., absorbing, specularly reflecting, diffusely reflecting).Type: ApplicationFiled: March 18, 2015Publication date: June 21, 2018Inventors: Jens GEIGER, Nicola SPRING, Robert LENART, Bassam HALLAL, Hakan KARPUZ

Publication number: 20180172489Abstract: A system and method for optimizing a fiber optic sensor by properly clocking or rotationally orienting a window with a fiber optic focuser. This method may include shining light through the focuser into the window and receiving with a reflectometer a first reflection from a first surface of the window and a second reflection from a second surface of the window. Next, the method may include calculating a delta of intensities between the first and second reflections, and then rotating an orientation of the window to a next rotational orientation. The steps of rotating the orientation of the window, receiving reflections, and calculating their delta may be repeated any plurality of times to solve for a plurality of deltas. Then, the method may include the steps of determining which one of the deltas is the largest and fixing the window to the focuser at a rotational orientation associated therewith.Type: ApplicationFiled: January 30, 2018Publication date: June 21, 2018Applicant: HONEYWELL FEDERAL MANUFACTURING & TECHNOLOGIES, LLCInventor: RYAND JEREMY FERGUSON TUCKER
