Publication number: 20240077526Abstract: Methods, systems, and devices for hardware noise filtering are described. A wearable device may emit light from a set of light emitting elements (e.g., light emitting diodes (LEDs)) based on a known input signal. The wearable device may measure an output signal at a set of photodetectors. The output signal may be generated by passing the light emitted from the set of light emitting elements into a material in contact with the wearable device. The wearable device may compare the known input signal to the output signal and may determine a hardware noise component of the output signal based on a known environmental noise component of the output signal and the comparison. The wearable device may store the hardware noise component for filtering hardware noise from sensor measurements.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Mika Petteri Kangas, Jukka- Tapani Mäkinen, Jaakko Tapio Vartiainen, Olli Petteri Heikkinen, Kirsi Marja Maansaari

Publication number: 20240000328Abstract: Methods, systems, and devices for wearable device are described. A wearable device may include a first light-emitting component positioned within an inner circumferential surface of the wearable device at a first radial position and a second light-emitting component positioned within the inner circumferential surface of the wearable device at a second radial position, where the first radial position and the second radial position define a segment of the inner circumferential surface between the first radial position and the second radial position. Additionally, the wearable device may include a photodetector configured to receive light emitted by the first light-emitting component and the second light-emitting component. In some cases, the photodetector may be positioned at a third radial position within the segment of the inner circumferential surface between the first radial position and the second radial position, where the third radial position is offset from a radial midpoint of the segment.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Inventors: Mika Petteri Kangas, Jukka-Tapani Mäkinen, Jaakko Tapio Vartiainen, Olli Heikkinen, Kirsi Marja Maansaari
