| Number | Title | Issue Date |
| 7110657 | Method of measuring circularity of an optical fiber Distortion introduced by an imaging system is characterized by positioning a generally cylindrical object and imaging optics in a first relative angular position about an axis of rotation that substantially coincides with the longitudinal axis of the object and empl... | 09/19/2006 |
| 7071480 | Sensor with alignment self compensation A material web attribute detection system with the material web having a first side and a second side. The system includes a radiation source located proximate to the first side of the material web and emitting radiation toward the material web, and a radiation dete... | 07/04/2006 |
| 5978053 | Characterization of collimation and beam alignment An apparatus and method for characterizing light beam collimation and alignment. A liquid crystal device receiving a light beam from a collimation lens has a lenslet array generated thereon. A corresponding array of point spread functions are detected by ... | 11/02/1999 |
| 5751011 | System for punching holes in a spinnerette A system for accurately determining the relative location of countersinks formed in a predetermined pattern in a spinnerette blank, accurately positioning a punching tool, in turn, over each countersink and, in turn, punching accurately positioned holes i... | 05/12/1998 |
| 5212392 | Optical sensing apparatus for detecting linear displacement of an object and method of operation thereof with detector matrix and centroid detection Apparatus for sensing linear displacement of an object between first and second locations along an axis is used to sense conditions that can be made to vary displacement of an object in accordance with the condition, such as temperature, pressure and rota... | 05/18/1993 |
| 5132546 | Object distance measurement with improved resolution through image centroid determination In a system for locating one object relative to another where one object is referenced to an active beacon and the other object is referenced to a solid state imaging device, circuitry determines the centroid of the image of the beacon as imposed on the i... | 07/21/1992 |
| 4929843 | Apparatus and method for determining a dimension of an object The height of an object is determined by projecting a beam of light there across to form a light stripe. A camera views the object obliquely, and forms an image of the light stripe. As a result of the oblique view, the light stripe is imaged as a series o... | 05/29/1990 |
| 4849643 | Optical probe with overlapping detection fields An optical probe for measuring various parameters of bent pipe comprises a substantially U-shaped housing defining a sensitive area across which light is projected from within the housing toward first and second light sensors mounted to the legs of the pr... | 07/18/1989 |
| 4748333 | Surface displacement sensor with opening angle control A surface displacement sensor is so designed that a stop or aperture for controlling an angle of opening is disposed at the position of a pupil of a detection optical system in which a slit image is focused on the surface to be detected and the light rays... | 05/31/1988 |
| 4441026 | Concentricity evaluating system A concentricity evaluating system has a stage supported by a hydrostatic bearing in at least one of radial and thrust directions. The angle of rotation of the stage is detected by a rotation angle detector. On the stage a hollow cylindrical member is fixe... | 04/03/1984 |
| 4261013 | Kinescope screen center locator An apparatus for locating the position of the horizontal centerline on the display screen of a television kinescope comprises two screen edge sensors disposed at the top and bottom of the display screen. The edge sensors are mounted on a vertically movabl... | 04/07/1981 |
| 4221973 | Linear array signal processing circuitry for locating the midpoint of a source of light Circuitry for locating the mid-point of a spot of illumination on a time-base-scanned linear photodetector (photodiode) array. With each scan, the array produces, from the illuminated photodiodes, a pulse made up of individual "pixils" having different di... | 09/09/1980 |
