Patent number: 10554886Abstract: Described herein are devices and techniques for managing power consumption of a position tracking device. The position tracking device may be a virtual reality (VR) controller having multiple optical sensors oriented to receive optical signals from different directions. A stationary optical emitter projects a laser line into a space and repeatedly scans the laser line through the space. For any given scan, some of the sensors may detect the laser line and some of the sensors may not detect the laser line because they are oriented away from the emitter or because of a blocking object. When an individual sensor fails to detect a laser scan, that sensor is disabled for one or more subsequent laser scans in order to reduce power consumption of the VR controller.Type: GrantFiled: May 18, 2018Date of Patent: February 4, 2020Assignee: Valve CorporationInventor: Rob Rydberg

Patent number: 10067234Abstract: A method of installing a projected beam detector can include providing a radiant energy source, providing a reflector, and projecting a radiant energy beam from the source to the reflector. A multi-pixel sensor or camera can be provided. The beam can be reflected from the reflector back to the sensor. A distance between the reflector and the camera can be determined based on a size of an image of the reflector incident on the camera. Where incident intensity corresponds to expected intensity for a predetermined distance, a sensitivity can be set based on the predetermined distance.Type: GrantFiled: February 17, 2015Date of Patent: September 4, 2018Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Scott Robert Lang, Mark C.

Patent number: 10029372Abstract: A system includes a machine assembly, an imaging sensor, an encoder, and one or more processors. The machine assembly is movable to actuate a brake lever of a vehicle in order to open a valve of an air brake system of the vehicle. The imaging sensor acquires perception information of a working environment that includes the brake lever. The encoder detects a displaced position of the machine assembly relative to a reference position of the machine assembly. The one or more processors detect a position of the brake lever relative to the machine assembly based on the acquired perception information and the detected displacement of the arm. The one or more processors generate a motion trajectory for the machine assembly that provides a path to the brake lever. The one or more processors drive movement of the machine assembly along the motion trajectory towards the brake lever.Type: GrantFiled: December 11, 2015Date of Patent: July 24, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Huan Tan, John Michael Lizzi, Douglas Forman, Charles Burton Theurer, Omar Al Assad, Mauricio Castillo-Effen, Romano Patrick, Balajee Kannan, Yonatan Gefen

Patent number: 9952421Abstract: The present disclosure relates to an apparatus (100) and method for controlling a plurality of simultaneously active optical traps (OT1,OT2,OT3). In one method, trapping beams (TB1,TB2,TB3) are provided and redirected for individually controlling a respective position (X,Y) of optical traps (OT1,OT2,OT3) formed by focusing of the redirected trapping beams in a sample volume (SV). Light (L11,L20) from the sample volume (SV) corresponding to the optical traps is received. A path of a detector beam (AB) is overlapped with one of the trapping beams (TB3), wherein the detector beam has a distinct wavelength (?A) from that of the overlapping trapping beam (TB3). In one channel, the light from the sample volume is filtered according to wavelength, and only the filtered light having the wavelength (?A) of the detector beam (AB) is measured.Type: GrantFiled: February 4, 2016Date of Patent: April 24, 2018Assignee: Stichting VUInventors: Andreas Sebastian Biebricher, Andrea Candelli, Iddo Heller, Niels Laurens, Erwin Johannes Gerard Peterman, Gijs Jan Lodewijk Wuite
