  • Publication number: 20250251703
    Abstract: A crown assembly of an electronic device may be configured to receive translational inputs, rotational inputs, and electrocardiogram (ECG) signals via a user input surface of a knob of the crown. The crown may include a shaft that extends from the knob at a first end and terminates at a second end, opposite the first end. The second end of the shaft may be conductively coupled to a conductive member of the crown assembly. A conductive viscous material may be positioned at an interface between the second end of the shaft and the conductive member. The shaft, the conductive viscous material, and the conductive member may define an electrical path carrying the ECG signal. A reservoir positioned at the interface area is defined by either the second end of the shaft, the conductive member, or both, and is filled with the conductive viscous material to help maintain the electrical path.

  • Patent number: 12003019
    Abstract: A portable or wearable electronic device can include a device housing defining an internal volume, and an electronic component disposed in the internal volume. The electronic component can be an input component and can have a component housing. The electronic device can also include an antenna feed assembly disposed in the internal volume. The antenna feed assembly can include a conductive grounding component electrically connected to the component housing and the device housing, and an antenna feed component electrically connected to the grounding component and disposed adjacent to the component housing. The conductive grounding component can surround a first major surface and a second major surface of the component housing.
