Publication number: 20230400366Abstract: A strain sensor that has an associated temperature compensation circuit. The strain sensor is temperature-compensated as it has a temperature compensation circuit that, when powered, applies an applied voltage across the applied voltage terminals of the strain sensor that has a compensating temperature dependency. That is, the applied voltage has a temperature dependency of one polarity that is opposite a temperature dependency of the strain sensor. Because of this temperature compensation, the signal representing strain has a more stable scale factor between the endured strain and the signal representing the strain. Thus, the accuracy of the strain sensor is improved.Type: ApplicationFiled: May 18, 2022Publication date: December 14, 2023Inventors: Xiao Chuan ONG, Wyatt Owen DAVIS

Publication number: 20230375822Abstract: A flip chip micromirror assembly comprising a micromirror chip that is flip chip mounted onto the circuit board via a bonding layer. The micromirror chip has a micromirror layer in which a micromirror is formed. The micromirror chip has a flip chip surface facing the electrode surface of the circuit board. The bonding layer includes conductive region(s) that electrically couples corresponding board electrodes with corresponding chip electrodes. However, the bonding layer is not interposed between the electrode surface of the circuit board and the micromirror itself. In other words, the bonding layer spaces the micromirror chip from the circuit board, and provides a gap underneath the micromirror between the micromirror chip and the circuit board. This gap is of sufficient thickness that the micromirror can be actuated with full movement without being mechanically obstructed by the circuit board.Type: ApplicationFiled: May 20, 2022Publication date: November 23, 2023Inventors: Xiao Chuan ONG, Di SUN, Joseph Michael LUIZZI, Wyatt Owen DAVIS

Patent number: 11714276Abstract: A microelectromechanical systems (MEMS) scanning device comprising a torsional beam flexure that has a variable width in relation to a rotational axis for a scanning mirror. The geometric properties of the torsional beam vary along the rotational axis to increase a desired mode of mechanical strain at a location where a strain sensor is operating within the MEMS scanning device to generate a feedback signal. The torsional beam flexure mechanically suspends the scanning mirror from a frame structure. During operation of the MEMS scanning device, actuators induce torsional deformation into the torsional beam flexure to cause rotation of the scanning mirror about the rotational axis. The degree or amount of this torsional deformation is directly related to the angular position of the scanning mirror and, therefore, the desired mode of mechanical strain may be this torsional deformation strain component.Type: GrantFiled: May 12, 2020Date of Patent: August 1, 2023Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Utku Baran, Xiao Chuan Ong, Wyatt Owen Davis

Patent number: 10802220Abstract: An integrated optical beam steering system is configured in three stages to provide beam steering for image light from an imager (e.g., laser, light emitting diode, or other light source) to downstream elements in a display system such as an exit pupil expander (EPE) in a mixed-reality computing device. The first stage includes a multi-level cascaded array of optical switches that are configurable to spatially route image light over a first dimension of a two-dimensional (2D) field of view (FOV) of the display system. The second waveguiding stage transfers the image light along preformed waveguides to a collimator in the third stage which is configured to collimate the image light along the first dimension of the FOV (e.g., horizontal). The waveguiding and collimating stages may be implemented using lightweight photonic crystal nanostructures.Type: GrantFiled: June 19, 2019Date of Patent: October 13, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Joshua Owen Miller, Kai Zang, Wyatt Owen Davis, Mohammadamin Eftekhar
