Patent number: 11950914Abstract: Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.Type: GrantFiled: November 21, 2022Date of Patent: April 9, 2024Assignee: Fitbit, Inc.Inventors: Faton Tefiku, Yonghua Wei, Kevin Li, Man-Chi Liu, Lindsey Michelle Sunden, Peter W. Richards, Dennis Jacob McCray, Christos Kinezos Ioannou, Kyung Nim Noh

Publication number: 20230270377Abstract: Approaches to determining a sleep fitness score for a user are provided, such as may be based upon monitored breathing disturbances of a user. The system receives user state data generated over a time period by a combination of sensors provided via a wearable tracker associated with the user. A system can use this information to calculate a sleep fitness score, breathing disturbance score, or other such value. The system can classify every minute within the time period as either normal or atypical, for example, and may provide such information for presentation to the user.Type: ApplicationFiled: May 5, 2023Publication date: August 31, 2023Inventors: Suraj Gowda, Conor Joseph Heneghan, Shelten Gee Jao Yuen, Anjian Wu, Daniel Joel Freschl, Peter W.

Publication number: 20230218181Abstract: An aspect of the disclosure pertains to a blood pressure measurement device and methods of controlling an inflation rate in a blood pressure measurement. An inflatable bladder of the blood pressure measurement device defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage. A pressure sensor of the blood pressure measurement device is configured to obtain blood pressure measurements, and a pump of the blood pressure measurement device is configured to inflate the inflatable bladder and control an inflation rate by controlling at least one of a duty cycle, a voltage, or a drive frequency.Type: ApplicationFiled: January 13, 2023Publication date: July 13, 2023Inventors: Dan Stefan Tudose, Xi Zhang, Keith Adam Wong, Andrew Larsen Axley, Peter W.

Patent number: 11418191Abstract: A capacitive sensing device can include multiple capacitive sensors. A first device controller is operatively connected to a portion of the capacitive sensors, while a second device controller is operatively connected to another portion of capacitive sensors. A common node or shield can be connected between the first device controller and the second device controller. Charging and discharging events of selected drive lines in the capacitive sensing device and/or of the common node or shield can be synchronized to reduce undesirable effects such as noise and/or to prevent the charging events and the discharging events from overlapping with each other. One or more reference capacitive sensors can be shared by the multiple device controllers.Type: GrantFiled: February 26, 2021Date of Patent: August 16, 2022Assignee: Apple Inc.Inventors: Christian M.

Publication number: 20210169345Abstract: Disclosed herein is a ring-shaped wearable device for detecting biometrics with a light source and a photodetector directed towards a digit wearing the ring-shaped device. The ring can thus detect oxygen saturation of a wearer based on light transmitted through the wearer's finger. The ring can include power saving measures to extend the battery life. A motion sensor can help determine opportune moments for data collection such as when the wearer is still. The motion sensor can be used to remove noise from the data caused by motion. After data is collected or during data collection, the ring can wirelessly communicate the data to another portable electronic device such as a phone or watch.Type: ApplicationFiled: December 16, 2020Publication date: June 10, 2021Inventors: Jaclyn Leverett Wasson, Peter W.
