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: 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.
