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

Patent number: 11850071Abstract: The accuracy of physiological data measured through contact with skin can be validated by characterizing the forces at the surfaces where data is measured. Conventional devices do not monitor the fit of skin-based sensors, making the accuracy and confidence in physiological data dependent on the user ensuring that the device is fitted properly. Over time, the seating of a device will vary due to changes in user activity and the need to periodically remove a device. Inevitably, instances will arise where the device is not fitted correctly, which may result in skewed physiological metrics. By monitoring the forces acting on the housing of a device, the interface of skin sensors can be characterized allowing for confidence metrics in the corresponding physiological data to be determined. In some cases, a user can be notified when a device is not seated properly, and in some cases, data may even be calibrated based on the fit of a device.Type: GrantFiled: June 28, 2019Date of Patent: December 26, 2023Assignee: Fitbit, Inc.Inventors: Brett Adam Coakley, Peter Colin Dess, Daniel Joel Freschl, Lindsey Michelle Sunden, Suraj Gowda, Tracy Norman Giest, Aditya Vivekanand Nadkarni

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.

Patent number: 10966643Abstract: Systems and devices of the present disclosure provide automated detection and tracking of carbon monoxide inhalation through non-invasive optical spectroscopy. A wearable device includes a light source coupled to the base and directing light towards a subject and a photodetector coupled to the base to receive light emitted by the light source through or reflected the subject. The light source emits light at a wavelength spectrum corresponding to a carboxyhemoglobin absorption spectrum and an oxyhemoglobin absorption spectrum. Biometric circuitry is coupled to the photodetector to receive a signal from the photodetector and process the signal to determine an intensity of the wavelengths present in the light received at the photodetector. The intensity of the wavelengths is indicative of a level of carbon monoxide inhalation associated with the subject.Type: GrantFiled: June 12, 2019Date of Patent: April 6, 2021Assignee: Fitbit, Inc.Inventors: Hamed Vavadi, Lindsey Michelle Sunden, Peter W.
