Patent number: 11962395Abstract: A whole-airspace satellite search method and device based on a phased array antenna are provided. The present disclosure combines electronic scanning implemented by the phased array antenna with mechanical scanning implemented by a mechanical actuator. As for low-orbit satellite communication, the present disclosure achieves rapid search and aiming through the phased array antenna, and solves the problem of limited electronic scanning angle of the phased array antenna through a servo system of the mechanical actuator. On the other hand, the present disclosure supports whole-airspace search and aiming of high, medium, and low-orbit satellites through the combination of the electronic scanning implemented by the phased array antenna and the mechanical scanning implemented by the mechanical actuator.Type: GrantFiled: September 6, 2023Date of Patent: April 16, 2024Assignee: CHINA STARWIN SCIENCE & TECHNOLOGY CO., LTDInventors: Qingan Li, Kesong Wu, Zhiqiang Zhang, Hansong Du

Patent number: 11771996Abstract: A method and system for verifying a client device's location in a parallel reality game hosted by a server. The client transmits its location to the server and receives verification instructions comprising a landmark and a verification pathway. The client prompts a player to capture image data of the landmark and, in response, receives a first set of image data of the landmark from an initial perspective. The client determines whether the first set of image data matches to the landmark before prompting the player to move along the verification pathway while capturing image data. The client receives a second set of image data of the landmark from a moving perspective. The client determines whether the second set of image data matches to an expected change in perspective of the landmark. Upon completion of the verification instructions, the client confirms to the server the client's location.Type: GrantFiled: April 6, 2022Date of Patent: October 3, 2023Assignee: NIANTIC, INC.Inventor: Hansong Zhang

Patent number: 11157073Abstract: A method for calibrating an orientation of an eye-mounted display relative to a user's gaze, preferably performed by a system. The system causes the eye-mounted display to project a calibration image onto the user's retina. The user provides information about a relative orientation between the user's gaze and the calibration image, for example a translation offset or a relative rotation. Based on the received information, an orientation for the eye-mounted display that aligns with the user's gaze is determined. Images to be projected by the eye-mounted display onto the user's retina can be adjusted based on the determined orientation.Type: GrantFiled: October 4, 2017Date of Patent: October 26, 2021Assignee: Tectus CorporationInventor: Hansong Zhang

Patent number: 10831269Abstract: A system controls a brightness of an augmented reality (AR) eye-mounted device. The system includes an eye-mounted display, a photodetector system, and a controller. The eye-mounted display includes a contact lens and a femtoprojector. The femtoprojector is contained in the contact lens and is configured to project an AR image to a user's retina. The AR image is overlaid on an external scene viewed by the user through the contact lens. The photodetector system detects a brightness level of the external scene. Based on the brightness level of the external scene, the controller adjusts a brightness level of the AR image projected to the user's retina. In some embodiments, the eye-mounted display receives image data defining the AR image and the controller adjusts a bit depth of the image data based on the brightness level of the AR image.Type: GrantFiled: September 6, 2019Date of Patent: November 10, 2020Assignee: Tectus CorporationInventors: Brian Elliot Lemoff, Michael West Wiemer, Paul Scott Martin, Hansong Zhang, Drew Daniel Perkins

Publication number: 20190302459Abstract: A pair of eye-mounted displays includes a right eye-mounted display and a right eye-mounted display. Each eye-mounted display comprises a contact lens. A femtoprojector system in each contact lens projects an image onto a retina of a user's eye when the contact lens is mounted on the user's eye. When the pair of eye-mounted displays is mounted on the user's left eye and on the user's right eye, a left-eye image is projected onto the user's left eye retina and a right-eye image is projected onto the user's right eye retina. The two projected images only partially overlap within the user's binocular visual field.Type: ApplicationFiled: March 27, 2018Publication date: October 3, 2019Inventors: Michael West Wiemer, Steven Louis Sinclair, Hansong Zhang, Brian Elliot Lemoff, Ben H.
