摘要： An electronic device may be provided with a display mounted in a housing. The display may have an array of pixels that form an active area and may have an inactive area that runs along an edge of the active area. An opaque layer may be formed on an inner surface of a display cover layer in the inactive area of the display or may be formed on another transparent layer in the electronic device. An optical component window may be formed from the opening and may be aligned with an ambient light sensor such as a color ambient light sensor. The color ambient light sensor may have an infrared-blocking filter to block infrared light such as infrared light emitted by an infrared- light-emitting diode in the device. A light diffuser layer, light guide, and other structures may also be included in the ambient light sensor.

摘要： 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.
摘要翻译： 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。

摘要： A head-mounted display may include a display system and an optical system that are supported by a housing. The optical system may be a catadioptric optical system having one or more lens elements. In one example, the optical system includes a single lens element and a retarder that is coated on a curved surface of the lens element. The retarder may be coated on an aspheric concave surface of the lens element. In another example the retarder may be coated on an aspheric convex surface of the lens element. One or more components of the optical system may be formed using a direct printing technique. This may allow for one or more adhesive layers and one or more hard coatings to be omitted from the optical system. A lens element may be directly printed on the display system to improve alignment between the optical system and the display system.

摘要： This relates to a device that detects a user's motion and gesture input through the movement of one or more tendons of the user's hand, arm, wrist, and fingers, for example, to provide commands to the device or to other devices. The device can be attached to, resting on, or touching the user's wrist, ankle or other body part. One or more optical sensors, inertial sensors, mechanical contact sensors, and myoelectric sensors can detect movements of the user's body. Based on the detected movements, a user gesture can be determined. The device can interpret the gesture as an input command, and the device can perform an operation based on the input command. By detecting movements of the user's body and associating the movements with input commands, the device can receive user input commands through another means in addition to, or instead of, voice and touch input, for example.
