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

Patent number: 10753030Abstract: A washing machine appliance, including one or more methods of operation, is provided herein. The washing machine appliance includes a wash basket rotatably mounted within a wash tub and being supported by a front bearing and a rear bearing. A method of operating the washing machine appliance includes rotating the wash basket within the wash tub at a basket speed and obtaining a front displacement amplitude, a rear displacement amplitude, and a wobble angle of the wash tub. Based at least in part on these measured values, front and rear bearing force amplitude thresholds and virtual bearing force values are calculated and compared. If the virtual bearing force value of either the front or rear bearing exceeds the respective bearing force amplitude threshold, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.Type: GrantFiled: July 11, 2018Date of Patent: August 25, 2020Assignee: Haier US Appliance Solutions, Inc.Inventor: Paul Owen Davis
