Publication number: 20230064273Abstract: Embodiments of this disclosure are directed to a wearable device having a housing, a display, and a sensor system. The display is at least partially surrounded by the housing. The sensor system is housed at least partially in the housing. The sensor system includes a first sensor, a second sensor, and a controller. The first sensor is configured to contact a body part of a user and generate a first signal. The second sensor is configured to sense a mechanical wave in an ambient environment of the wearable device and generate a second signal. The controller is configured to generate a resultant signal by removing noise from the first signal using the second signal, and determine a health parameter of the user from the resultant signal.Type: ApplicationFiled: August 30, 2022Publication date: March 2, 2023Inventors: Wegene H.

Patent number: 11045117Abstract: The provided disclosure relates to systems and methods for determining the axial orientation and location of a user's wrist using one or more sensors located on the strap, the device underbody, or both. For example, the strap can include a plurality of elastic sections and a plurality of rigid sections. Each elastic section can include one or more flex sensors. In some examples, one or more electromyography (EMG) sensors can be included to measure the user's electrical signals, and the user's muscle activity can be determined. In some examples, a plurality of strain gauges can be included to generate one or more signals indicative of any changes in shape, size, and/or physical properties of the user's wrist. In some examples, the device can include a plurality of capacitance sensors for increased granularity and/or sensitivity in measuring the amount of tension exerted by the user's wrist.Type: GrantFiled: September 6, 2018Date of Patent: June 29, 2021Assignee: Apple Inc.Inventors: Jason Lor, Siddharth Nangia

Patent number: 10624214Abstract: Readily manufactured structures for sealing or encapsulating devices in system-in-a-package modules, such that the modules are easily assembled, have a low-profile, and are space efficient. One example may provide readily manufactured covers for SIP modules. These modules may be easily assembled by attaching the cover to a top side of a substrate. These SIP modules may have a low-profile, for example when their height is reduced using one or more recesses in a bottom surface of a top of the recess, where the one or more recesses are arranged to accept one or more components. These SIP modules may be made space efficient by placing an edge of a cover near an edge of the substrate and connecting the plating of the cover using side plating on, or vias through, the substrate.Type: GrantFiled: February 11, 2016Date of Patent: April 14, 2020Assignee: Apple Inc.Inventors: Amir Salehi, Takayoshi Katahira, Vu T.

Patent number: 10250289Abstract: An electronic device may have a display cover layer mounted to a metal housing. Electrical component layers such as a display layer, touch sensor layer, and near-field communications antenna layer may be mounted under the display cover layer. An antenna feed may have a positive feed terminal coupled to the electrical component layers and a ground feed terminal coupled to the metal housing. The electrical component layers may serve as an antenna resonating element for an antenna. The antenna may cover cellular telephone bands and may receive satellite navigation system signals. A system-in-package device may be mounted to the metal housing. A flexible printed circuit may extend between the electrical component layers and the system-in-package device. A mounting bracket for the system-in-package device may be provided with electrical isolation to enhance antenna performance in bands such as a satellite navigation system band.Type: GrantFiled: September 6, 2016Date of Patent: April 2, 2019Assignee: Apple Inc.Inventors: Yi Jiang, Jiangfeng Wu, Lijun Zhang, Siwen Yong, Jiaxiao Niu, Mattia Pascolini, Jayesh Nath, Carlo Di Nallo, Zheyu Wang, Mario Martinis, Eduardo Jorge Da Costa Bras Lima, Steven P.
