    Abstract: A multi-touch sensor panel is disclosed that can be produced by forming a plurality of first traces of substantially transparent conductive material on a first substrate, forming a plurality of second traces of the substantially transparent material, and creating a fluid-tight gap between the plurality of first traces and the plurality of second traces. The fluid-tight gap can then be filled with a fluid having substantially no bubbles and an optical index similar to the optical index of the first and second traces to make the gap and the first and second traces substantially transparent. The second and first traces can be oriented to cross over each other at crossover locations separated by the fluid, the crossover locations forming mutual capacitance sensors for detecting touches.

    Abstract: A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.

    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。

    Abstract: An optical sensor can be multiplexed for different clients/features including estimating information or characteristics of a user's physiological signals. Additionally, the clients/features can include estimating information or characteristics independent from a user's physiological signals. As the number of clients increase and/or as the requirements for the clients increase, flexibility can be provided to accommodate the various clients. Parallelization of the optical sensor can be used to improve performance as the number of clients increase. For example, the hardware and software architecture can assemble patterns of time slots that measure all desired light paths for the multiple clients and distribute the corresponding measurements to each client according to the client requests. In some examples, the scanning sequence can be represented by frames including slots associated with multiple clients to compress the representation for larger or more complex scan sequences.
