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

Patent number: 11857336Abstract: Arousal events can be determined for a user associated with a wearable device, such as a user wearing a wearable computing device including one or more sensors. The one or more sensors may obtain EDA information that may determine a sympathetic nervous system response of the user, which may be responsive to an arousal event or an activation. Detection of events that increase the EDA response may provide information to the user regarding arousal events and provide recommendations to the user to address the arousal events to decrease their response.Type: GrantFiled: August 17, 2021Date of Patent: January 2, 2024Assignee: FITBIT LLCInventors: Man-Chi Liu, Alexander Statan, Derrick Steven Vickers, Paul Francis Stetson, Elena Perez, James Horng-Kuang Lin, Belen Lafon, Lindsey Michelle Sunden
