    Abstract: In some examples, an optical encoder may consist of a light source that shines light onto a wheel which then reflects the light onto a sensor. Using information encoded in the reflected light, the rotation of the wheel may be determined. In some examples, rotation of the wheel may be determined by detecting an encoding pattern in light reflected from an exterior surface of the wheel. In some examples, the encoding pattern can be a pattern of light and dark stripes. In some examples, a pattern of light stripes can be generated from light reflecting off of reflective portions of the wheel. Some examples of the disclosure relate to using a surface topology for a wheel that can be used to generate an encoding pattern of light and dark stripes in light reflected from the surface of the wheel, even when the surface of the wheel is uniformly reflective.

    Abstract: A portable electronic device including one or more sensors for detecting ambient light through the user's skin is dis-closed. The sensors can be optical sensors such as ambient light sensors (ALS) and/or cameras. Examples of the present disclosure include a device that can determine the intensity of ambient light and can change the operating state of the portable electronic device based on the ambient light environment. The device can also determine the type of ambient light and generate notifications to the user based on the determined type.

    Abstract: A portable electronic device include one or more electrodes for calculating distances and rotational angles between the device and the user is disclosed. Based on the calculated distances and rotational angles, a physical activity of the user can be determined. Additionally, the calculated distances and rotational angles can be used for compensation of optical artifacts in one or more signals detected by the device. User movement or physical activity can introduce optical artifacts, which can lead to erroneous determination of the one or more characteristics. The calculated distances and rotational angles can be used to reduce or remove the optical artifacts, leading to a more accurate determination of the one or more characteristics of the user.

    Abstract: A PPG signal may be obtained from a pulse oximeter, which employs a light emitter and a light sensor to measure the perfusion of blood to the skin of a user. However, the signal may be compromised by noise due to motion artifacts. That is, movement of the body of a user may cause a gap between the tissue of a user and the electronic device, introducing noise to the signal. Further, the noise introduced may vary depending on how close the light emitter is to the light sensor. Accordingly, to address the presence of motion artifacts, examples of the present disclosure can receive light information at a light sensor from two different light emitters, each at a different distance from the light sensor along a surface of the electronic device, one relatively close to the light sensor and one relatively far from the light sensor.

    Abstract translation: PPG信号可以从采用光发射器和光传感器的脉搏血氧计获得，以测量血液对使用者皮肤的灌注。 然而，由于运动伪影，该信号可能被噪声所损害。 也就是说，用户身体的运动可能导致用户的组织与电子设备之间的间隙，向信号引入噪声。 此外，引入的噪声可以根据光发射器与光传感器的接近程度而变化。 因此，为了解决运动伪影的存在，本公开的示例可以从光传感器接收来自两个不同光发射器的光信息，每个光发射器在距离光传感器沿着电子设备的表面不同的距离处，一个相对靠近 光传感器和一个相对远离光传感器。
