Patent number: 11974047Abstract: Various embodiments include a light source module with one or more light emitters and one or more light sensors that share an aperture via which light passes. One of the light sensors may measure illuminance received through the aperture (not illuminance from the light emitters) and send a signal indicating a measurement of the illuminance. The light source module may be integrated into a portable computing device having a controller. The controller may include logic to perform one or more device operations based on the measurement of illuminance, such as, but not limited to, controlling a device display brightness and/or controlling an auto exposure feature of the device camera. Calibration parameters for interpreting the signal may be determined via a calibration process.Type: GrantFiled: September 7, 2021Date of Patent: April 30, 2024Assignee: Apple Inc.Inventors: Angelo M Alaimo, Shahrooz Shahparnia, Paul V.

Publication number: 20240103301Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: Victoria C.

Patent number: 8026501Abstract: A method that may be applied to imaging and identifying defects and contamination on the surface of an integrated circuit is described. An energetic beam, such as an electron beam, may be directed at a selected IC location having a layer of a solid, fluid, or gaseous reactive material formed over the surface. The energetic beam disassociates the reactive material in the region into chemical radicals that either chemically etch the surface preferentially, or deposit a thin layer of a conductive material over the local area around the energetic beam. The surface may be examined as various layers are selectively etched to decorate defects and/or as various layers are locally deposited in the area around the energetic beam. SEM imaging and other analytic methods may be used to identify the problem more easily.Type: GrantFiled: August 26, 2010Date of Patent: September 27, 2011Assignee: Micron Technology, Inc.Inventors: Mark J. Williamson, Paul M. Johnson, Shawn D. Lyonsmith, Gurtej S. Sandhu, Justin R. Arrington
