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.

Ring for optically measuring biometric data

Low-profile latching mechanisms and related mechanical interfaces for allowing straps and other fastening accessories for limb-wearable devices are provided. The mechanisms in question allow for a very strong, yet easily releasable, connection to be made between a strap accessory and a device housing, with very little of the mechanism being visible.

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.
