| Number | Title | Issue Date |
| 4715714 | Measuring device for determining relative position between two items The measuring device is used for determining a relative position between a first item and a second item or the image thereof. The items are displaceable or rotatable relative to one another. The first item has a code carrier, which is arranged along a pat... | 12/29/1987 |
| 4668862 | Method and apparatus for determining measured quantities with a centroid detecting encoder A plurality of marks are carried on a movable member, the position of which represents a measured quantity. An image of a mark is projected onto a surface having a large number of detectors. The output signals of the detectors are fed into an evaluation c... | 05/26/1987 |
| 4572952 | Position sensor with moire interpolation A position sensor has a scale consisting of tracks of indicia in the form of bar patterns acting on a detector having a two-dimensional array of sensitive elements. One track has indicia with a pitch slightly greater than the pitch of the sensitive elemen... | 02/25/1986 |
| 4573000 | Measuring instrument In an incremental measuring instrument for measuring the relative position of two objects, of the type including reference marks absolutely positioned with respect to a graduation of a scale, a first scanning plate with scanning fields for the graduation ... | 02/25/1986 |
| 4484816 | Apparatus for measuring length or angle A light image of a scale, which bears length or angle information recorded in the form of a bright and dark bit pattern, is projected onto the light receiving surface of a storage effect type sensor, whereby a charge pattern data corresponding to the proj... | 11/27/1984 |
| 4465373 | Encoder An interpolation encoder comprising a sensor array, a code plate arranged in opposition to the sensor array and having a plurality of groups of lattice patterns, and an arithmetic unit for processing data of the code plate detected by the sensor array. Th... | 08/14/1984 |
| 4275965 | Long stroke, high resolution optical position sensor A high resolution optical position sensor for measuring the linear displacement of a reciprocating device with a long stroke, includes a code plate having a substrate comprised of a fiber optic faceplate having a plurality of parallel optical waveguides w... | 06/30/1981 |
