Abstract: 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.

Abstract: 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.

Abstract: Various embodiments provide a wellness tracking device with a base plate that may be utilized as a combination electrode by a variety of sensors. The base plate may be a multi-material electrode that includes a conductor and a transparent or semi-transparent material to enable optical sensing. In certain embodiments, the base plate supports a plurality of different sensors, which may selectively utilize the base plate as an electrode.

Abstract: 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.

Abstract: Sleep tracking systems and techniques for monitoring two or more co-sleepers in a single bed are disclosed. Such systems and techniques may incorporate sleeper identification, as well as various non-user-specific aspects. Some implementations may incorporate user-specific or user-tailored alarm functionality.

Abstract: An optical measurement module is disclosed that includes three or more recessed regions separated from each other by two or more barrier walls, the recessed regions including at least two distal recessed regions. The optical measurement module may also include first and second photo-emitter elements that emit light in different spectrums and first and second photodetector elements. One or more of the second photo-emitter elements may be located in one of the distal recessed regions, and the second photodetector element may be located in one of the other distal recessed regions. The first photodetector element may be located in a recessed region other than the recessed region where the second photodetector element is located, and the one or more photo-emitter elements may be located in one of the recessed regions other than the one where the first photodetector element is located.

Such optical physiological parameter measurement devices or sensors may include two photodetectors and a photo-emitter, as well as barrier walls that are interposed between the photo-emitter and the photodetectors. The barrier walls may have recesses that intermesh with surface profiles of protrusions that are attached to or part of a window of the optical physiological parameter measurement devices or sensors.

Abstract: Light-blocking structures for optical physiological parameter measurement devices or sensors are disclosed. Such structures may include barrier walls and protrusions that further include intermeshing surface profiles designed to promote light-blocking capabilities at small scales to offset potential gaps that may occur due to assembly tolerance stack-ups.

Abstract: A transcription module having a mounting unit, acoustical receivers and an EM detector is disclosed. The mounting unit is adapted for positioning the transcription module over a work surface. First and second acoustical receivers are attached to the mounting unit. Each acoustical receiver includes a microphone positioned over a corresponding location on the work surface. Each microphone views the work surface at the corresponding location and is configured to receive acoustical signals from an input device operating over the work surface at another location. The EM detector detects an EM signal that is synchronized with the acoustical signals.
