Publication number: 20240114295Abstract: Embodiments of this application provide a method for identifying an earbud wearing error. An earbud wearing action is detected based on a sensor of an earbud (for example, an acceleration sensor, a gyroscope sensor, or a magnetic field detection sensor), and an electronic device may determine, based on the earbud wearing action, whether a left bud and a right bud are incorrectly worn. Once it is determined that the left bud and the right bud are incorrectly worn, the electronic device may output prompt information by using a screen, to prompt a user that the left bud and the right bud are incorrectly worn. When the left bud and the right bud are incorrectly worn, the electronic device may further switch between a left-ear mode and a right-ear mode.Type: ApplicationFiled: January 18, 2022Publication date: April 4, 2024Inventor: Guocheng Hu

Publication number: 20230402472Abstract: An electronic device may include an ambient light sensor or other semiconductor sensor. The sensor may produce signals in response to light incident on the electronic device and therefore incident on the sensor. In some cases, components within the electronic device, such as infrared components, or external light sources may interfere with the operation of the sensor. Therefore, the sensor may include a filter that transmits at least a portion of visible light while blocking infrared light. Because light may be incident on the electronic device from a variety of angles, a diffuser in the sensor may scatter the light into a desired angular distribution. To ensure that infrared light is blocked regardless of the angle of the incident light, the filter may include both thin-film dielectric layers and metal layers. The metal layers may be interleaved with the thin-film dielectric layers.Type: ApplicationFiled: March 28, 2023Publication date: December 14, 2023Inventors: Ove Lyngnes, Paul J Gelsinger, Yijing Chen, Guocheng Shao, Louis W Baum, Kenneth J Vampola, Avery P Yuen
