Publication number: 20240126368Abstract: An eye tracking system for a head-mounted devices includes an interference pattern emitter, an interference pattern detector, and processing logic. The interference pattern emitter provides at least two light beams that combine into a light pattern in an eyebox region of the head-mounted device. The light pattern includes an interference pattern based on constructive and destructive interference of the at least two light beams. The light detector is configured to detect a portion of the light pattern and provides detector data that is representative of one or more light intensities in the portion of the light pattern. The processing logic is coupled to the light detector to receive the detector data and is configured to identify displacement characteristics of the interference pattern. The processing logic is configured to determine orientation characteristics of an eye in the eyebox region based on the displacement characteristics.Type: ApplicationFiled: September 15, 2023Publication date: April 18, 2024Inventors: Mantas Zurauskas, James Schloss, Pavel Trochtchanovitch

Patent number: 9903934Abstract: A dimensional measuring device sends a beam of light to a remote probe having a retroreflector and a pitch/yaw sensor. The pitch/yaw sensor passes the light through an aperture and a lens to a position sensor that generates an electrical signal indicative of the position of the received light. A processor uses the electrical signal to determine a pitch angle and a yaw angle of the remote probe.Type: GrantFiled: June 28, 2016Date of Patent: February 27, 2018Assignee: FARO TECHNOLOGIES, INC.Inventors: Mathieu Antoina, Lawrence B. Brown, Jonathan R. Day, Matthew Frederick Evans, Ricardo Martins, Jacob J. Mertz, John Mountney, Robert Mark Neal, James Schloss, Quintin Stotts, Ding Wang, Robert E. Bridges

Patent number: 9091803Abstract: An optical apparatus for delivering to a flow-cell of a flow-cytometer a plurality of beams of laser radiation each thereof having a different wavelength. The apparatus includes a dispersion compensation-prism and a plurality of directing-prisms equal in number to the number of laser-beam. The directing-prisms are arranged to direct the laser radiation beams directly therethrough into the dispersion compensation-prism as converging fan of beams in a first plane. The beams are transmitted by the compensation-prism as a converging fan of beams intersecting then proceeding as a diverging fan of beams in the first plane. A spherical focusing lens is arranged cooperative with a cylindrical lens for focusing the plurality of laser-beams as a plurality of spaced apart elongated focal spots in a plane in which the cytometer flow-cell is located.Type: GrantFiled: July 15, 2014Date of Patent: July 28, 2015Assignee: Coherent, Inc.Inventors: Lei Meng, Jordan Wesley Crist, Michele Wayne Winz, James Schloss

Patent number: 9059346Abstract: A laser-radiation sensor includes a copper substrate on which is grown an oriented polycrystalline buffer layer surmounted by an oriented polycrystalline sensor-element of an anisotropic transverse thermoelectric material. An absorber layer, thermally connected to the sensor-element, is heated by laser-radiation to be measured and communicates the heat to the sensor-element, causing a thermal gradient across the sensor-element. Spaced-apart electrodes in electrical contact with the sensor-element sense a voltage corresponding to the thermal gradient as a measure of the incident laser-radiation power. At least two protection layers are positioned between the sensor layer and the absorber layer.Type: GrantFiled: July 17, 2013Date of Patent: June 16, 2015Assignee: Coherent, Inc.Inventors: Robert Semerad, Erik Krous, James Schloss
