Abstract: In embodiments of wearable device heart monitor systems, a wearable device has electrical contacts integrated in a housing base of the wearable device as electrodes designed to contact skin of a user while wearing the wearable device. A housing bezel of the wearable device designed as an additional point of contact on the wearable device. The wearable device includes an electromyography (EMG) system to receive electrical signals from at least two of the electrodes and detect muscular movement of the user. Further, the wearable device includes an electrocardiogram (ECG) system to receive and combine the electrical signals from the electrodes when the user touch contacts the housing bezel while wearing the wearable device to complete an ECG loop between the electrodes and the housing bezel for a heart rate reading of the user.

Abstract: This disclosure describes techniques and apparatuses for rotational alignment of a circular display and a circular lens. In one or more implementations, a display device, such as a smart watch, includes a circular lens assembly that overlays a circular display assembly. The display device includes at least two alignment points positioned along the perimeter of the circular display assembly that enable a machine vision system to rotationally align the circular display assembly to the circular lens assembly. At least one of the alignment points includes a target mark on the perimeter of the circular lens assembly that is viewable by the machine vision system through a corresponding alignment hole on the perimeter of the circular display assembly. The alignment hole is within a border region of the circular display assembly, but is sized and positioned so that it does not impact the structure of the circular display assembly.

Abstract: In embodiments of an embedded light sensing component, a lens assembly includes a display component to display a user interface, such as when implemented in a wearable device. The lens assembly has a lens structure that covers the display component. The lens assembly also includes a light sensor that is implemented to sense ambient light in an environment proximate the lens structure, where the light sensor is embedded between the display component and the lens structure of the lens assembly.
