    Abstract: Embodiments of this disclosure are directed to a wearable device having a housing, a display, and a sensor system. The display is at least partially surrounded by the housing. The sensor system is housed at least partially in the housing. The sensor system includes a first sensor, a second sensor, and a controller. The first sensor is configured to contact a body part of a user and generate a first signal. The second sensor is configured to sense a mechanical wave in an ambient environment of the wearable device and generate a second signal. The controller is configured to generate a resultant signal by removing noise from the first signal using the second signal, and determine a health parameter of the user from the resultant signal.

    Abstract: This relates to systems and methods for determining the axial orientation and location of the user's wrist using one or more sensors located on the strap, the device underbody, or both. For example, the strap can include a plurality of elastic sections and a plurality of rigid sections. Each elastic section can include one or more flex sensors. In some examples, on or more electromyography (EMG) sensors can be included to measure the user's electrical signals, and the user's muscle activity can be determined. In some examples, a plurality of strain gauges can be included to generate one or more signals indicative of any changes in shape, size, and/or physical properties of the user's wrist. In some examples, the device can include a plurality of capacitance sensors for increased granularity and/or sensitivity in measuring the amount of tension exerted by the user's wrist.

    Abstract: Embodiments relate to systems and methods for forming a circuit assembly for an electronic device. The circuit assembly may include a substrate and a group of surface-mounted electronic components disposed on a surface of the substrate. An electrical connector may be disposed on the surface and may be configured to receive an electrical connection from a separate electrical component or assembly. A molded layer may be formed over at least a portion of the surface fully encapsulating the group of surface-mounted electronic components and partially encapsulating the electrical connector.

    Abstract: An electronic device has an electronic device housing containing electrical components such as integrated circuits and other components. The electronic device housing may be provided with an interconnect stack that has layers of dielectric and metal traces forming signal paths. Electrical components may be mounted on printed circuits. Coupling structures such as screws or other fasteners, washers, standoffs, nuts, springs, and spring-loaded pins may be used in forming signal paths that couple the signal paths of the interconnect stack to components such as buttons, batteries, printed circuits with integrated circuits, displays, and other circuitry.

    Abstract: A blood pressure measurement device may include one or more piezoelectric sensors (e.g., differential piezoelectric sensors) for detecting blood flow through a limb of a user as part of determining blood pressure measurements. The piezoelectric sensor(s) may additionally or alternatively be used to determine one or more biological parameters of users (e.g., a ballistocardiogram, a heart rate, a heart rate variability, and a pulse wave velocity). The blood pressure measurement device may additionally or alternatively include a capacitive sensor for determining a pressure applied to the limb of the user by the blood pressure measurement device and/or operational states of the blood pressure measurement devices (off-arm, on-arm, inflating, deflating, tightness, and the like).
