Patent number: 11914780Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.Type: GrantFiled: August 11, 2022Date of Patent: February 27, 2024Assignee: Apple Inc.Inventors: Paul X Wang, Alex J. Lehmann, Michael J. Rockwell, Michael Y. Cheung, Ray L. Chang, Hongcheng Sun, Ian M. Bullock, Kyle J. Nekimken, Madeleine S. Cordier, Seung Wook Kim, David H. Bloom, Scott G. Johnston

Publication number: 20240061520Abstract: A system may include an electronic device such as a head-mounted device and a handheld input device for controlling the electronic device. The handheld input device may include a stylus and a removable sleeve on the stylus. The input-output capabilities of the handheld input device may be shared between the stylus and the removable sleeve. The stylus may include touch sensor circuitry, a force-sensitive tip, and a motion sensor. The sleeve may include conductors for translating touch input on the sleeve to the touch sensor circuitry on the stylus, a deformable member for translating forces on the sleeve to the force-sensitive tip of the stylus, and visual markers that can be detected by an external camera and used with motion sensor data from the stylus to track the handheld input device. The removable sleeve may include haptic output devices and a battery and may be attached to an item without electronics.Type: ApplicationFiled: July 12, 2023Publication date: February 22, 2024Inventors: Paul X Wang, Ray L Chang

Publication number: 20230351672Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user’s environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.Type: ApplicationFiled: June 29, 2023Publication date: November 2, 2023Applicant: Apple Inc.Inventors: Arthur Y. Zhang, Ray L. Chang, Timothy R. Oriol, Ling Su, Gurjeet S. Saund, Guy Cote, Jim C. Chou, Hao Pan, Tobias Eble, Avi Bar-Zeev, Sheng Zhang, Justin A. Hensley, Geoffrey Stahl

Publication number: 20230333377Abstract: A display system includes a head-mounted display unit and a wake control system. The head-mounted display unit provides content to a user and is operable in a low-power state and a high-power state that consumes more power to provide the content to the user than the low-power state. The wake control system determines when to operate in the high-power state. The wake control system may assess a first wake criterion with low power, assess a second wake criterion with higher power than the first wake criterion upon satisfaction of the first wake criterion, and cause the head-mounted display unit to operate in the high-power state upon satisfaction of the second wake criterion.Type: ApplicationFiled: June 22, 2023Publication date: October 19, 2023Inventors: Fletcher R. Rothkopf, David A. Kalinowski, Jae Hwang Lee, Avi Bar-Zeev, Grant H. Mulliken, Paul Meade, Nathanael D. Parkhill, Ray L. Chang, Arthur Y. Zhang

Publication number: 20230314828Abstract: Fiducial patterns that produce 2D Barker code-like diffraction patterns at a camera sensor are etched or otherwise provided on a cover glass in front of a camera. 2D Barker code kernels, when cross-correlated with the diffraction patterns captured in images by the camera, provide sharp cross-correlation peaks. Misalignment of the cover glass with respect to the camera can be derived by detecting shifts in the location of the detected peaks with respect to calibrated locations. Devices that include multiple cameras behind a cover glass with one or more fiducials on the cover glass in front of each camera are also described. The diffraction patterns caused by the fiducials at the various cameras may be analyzed to detect movement or distortion of the cover glass in multiple degrees of freedom.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Applicant: Apple Inc.Inventors: Tushar Gupta, Aleksandr M. Movshovich, Arthur Y. Zhang, Ray L. Chang, Fletcher R. Rothkopf

Patent number: 11009949Abstract: A wearable electronic device comprises a multi-segment force sensor and a signal aggregator. The sensor comprises at least a first segment and a second segment connected to a flexible substrate material. A first portion of the substrate material (to which the first segment is attached) and a second portion of the substrate material (to which the second segment is attached) collectively wrap at least partially around a portion of an individual's body. The signal aggregator receives respective signals indicative of forces applied by an individual to the segments, and causes a representation of the respective signals to be transmitted to an application processing engine.Type: GrantFiled: August 7, 2018Date of Patent: May 18, 2021Assignee: Apple Inc.Inventors: John G.
