Patent number: 11902655Abstract: Methods, systems, and apparatus for an infrared and visible imaging system. In some implementations, Image data from a visible-light camera is obtained. A position of a device is determined based at least in part on the image data from the visible-light camera. An infrared camera is positioned so that the device is in a field of view of the infrared camera, with the field of view of the infrared camera being narrower than the field of view of the visible-light camera. Infrared image data from the infrared camera that includes regions representing the device is obtained. Infrared image data from the infrared camera that represents the device is recorded. Position data is also recorded that indicates the location and pose of the infrared camera when the infrared image data is acquired by the infrared camera.Type: GrantFiled: January 30, 2023Date of Patent: February 13, 2024Assignee: X Development LLCInventors: Leo Francis Casey, Peter Light, Joel Fraser Atwater, Crystal Elayna Winston, Mehrdad Roosta, Siyuan Xin, Chetan Mahadeswaraswamy

Patent number: 11513166Abstract: Methods, systems, and apparatus, including computer programs stored on a computer-readable storage medium, for obtaining, from an electric field sensor, measurements of a net electric field resulting from a combination of respective electric fields from two or more electrical power conductors that are proximate to the electric field sensor. The apparatus detects a change in successive measurements of the net electric field. The apparatus determines, based on the change, that an electrical fault has occurred in one of the two or more electric power conductors. The apparatus sends to a server system, data indicating that the electrical fault has occurred in one of the two or more electric power conductors.Type: GrantFiled: July 12, 2021Date of Patent: November 29, 2022Assignee: X Development LLCInventors: Leo Francis Casey, Siyuan Xin

Patent number: 11500005Abstract: Methods, systems, and apparatus, including computer programs stored on a computer-readable storage medium, for obtaining a reference phase signal that is synchronized with an alternating current (AC) phase of a multi-phase electrical power distribution system. The apparatus obtains output signals from sensors, each output signal representative of an electromagnetic emission detected by a respective sensor. The apparatus identifies, based on comparing respective phases of the output signals to the reference phase signal, a particular AC phase of the multi-phase electrical power distribution system associated with a source of the emissions. The apparatus provides an indication of the particular AC phase to a user.Type: GrantFiled: April 29, 2021Date of Patent: November 15, 2022Assignee: X Development LLCInventors: Leo Francis Casey, Siyuan Xin, Peter Evans, Shuyu Wang, Raymond Daly, C.
