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
