Patent number: 11927758Abstract: A display system includes a wearable eyewear arrangement with a projector for propagating display light associated with an image and a waveguide for propagating the display light to an eye box. The waveguide includes volume Bragg gratings (VBGs), which may be in groups of three or more gratings with same horizontal period allowing each color to be coupled out from the waveguide by the same type of grating, thus, at the same angle, reducing or eliminating image blurriness and ghost images while allowing a smaller size waveguide. A 100% reflective mirror or mirror array is used for broad spectrum reflection into the waveguide for light input. Selection of two or more wavelengths for each color at the projector provides spectral response matching to the waveguide allowing wider field of view (FOV) coverage for the entire wavelength spectrum.Type: GrantFiled: November 17, 2022Date of Patent: March 12, 2024Assignee: META PLATFORMS TECHNOLOGIES, LLCInventors: Wai Sze Tiffany Lam, Wanli Chi, Dominic Meiser, Yang Yang, Ningfeng Huang

Patent number: 11886765Abstract: A head-mounted display device, where when the head-mounted display device enables a low power consumption display mode, a left-eye display system and a right-eye display system alternately display an image. A switching time interval for the left-eye display system and the right-eye display system to alternately display the image is determined based on a current display mode. Different current display modes correspond to different switching time intervals, or correspond to a same switching time interval. Therefore, in the low power consumption display mode of the head-mounted display device, one display system displays the image within a same time period to reduce power consumption of the head-mounted display device.Type: GrantFiled: May 30, 2020Date of Patent: January 30, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventor: Chunjing Mao

Patent number: 11875006Abstract: Techniques are described for using an alternating-current-mode (AC-mode) bridge for low-noise self-capacitor sensing in a capacitive touch panel array integrated with a display panel. Each channel of the array has a self-capacitance (Ci) that changes responsive to presence or absence of a local touch event local. Pairs of channels are read out differentially by coupling pairs of channels to branches of an AC-mode bridge. The AC-mode bridge includes current sources that drive each branch (and thereby each channel) with a sinusoidal current, manifesting a branch voltage on each branch based on the self-capacitance of the branch. The branch voltages are used to generate an output voltage. The sinusoidal current is controlled by comparing a driver signal with feedback from the branches, so that common-mode noise on the channels becomes a common-mode component of the sinusoidal currents and is rejected in the generation of the output voltage.Type: GrantFiled: March 21, 2023Date of Patent: January 16, 2024Assignee: Shenzhen Goodix Technology Co., Ltd.Inventors: Chao Yang, Mohamed Elsayed, Dazhi Wei

Patent number: 11868608Abstract: Systems, methods, and instrumentalities are described herein related to a secured stylus. A secure connection is established between a digitizer processor in a computing device and a remote server providing virtual desktop infrastructure (VDI). A digitizer interposer implemented in the computing device, the server, and/or between them receives raw or encrypted digitizer input that bypasses the operating system (OS) and processor of the computing device. Digitizer signal processing, normally performed by the OS, is performed on one or more servers. An edge server provides haptic feedback to a stylus and/or generates display of temporary digital ink as created while a cloud server completes digital ink processing and generates video for display by the computing device. A secure connection between a graphics processing unit (GPU) and the server protects secure connection video by encryption bypassing the OS and processor of the user computing device.Type: GrantFiled: March 20, 2023Date of Patent: January 9, 2024Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Shoham Dekel, Assaf Bar-Ness, Orr Srour
