Abstract: Methods of optimizing performance for a wearable device are described herein, as are systems and wearable devices for performing the methods. One example method includes selecting, based on first and second sensor data, a current position of a portion of a wearable device donned by a user relative to the user's body from among at least three predefined positions of the portion. The method further includes, after selecting the current position of the portion based on the first and second sensor data, determining whether to modify an operating characteristic of the wearable device based on the current position. The method further includes, in accordance with a determination that an operating characteristic should be modified based on the current position, modifying a first operating characteristic for a display subsystem of the wearable device or a second operating characteristic for a communication subsystem of the wearable device.

Abstract: The disclosed system may include an enclosure that is configured to house internal electrical components disposed on a printed circuit board (PCB). The system may also include a first antenna feed that is electrically connected to the PCB, to the enclosure, and to a radiating coupling arm configured for wireless communication in a first wireless communication band. The system may further include a second antenna feed that is electrically connected to the PCB and to an antenna configured for wireless communication in a second, different wireless communication band. The system may also include a first grounding leg that forms an electrical ground between the PCB and the enclosure, and a second, switchable grounding leg positioned away from the first grounding leg. This switchable grounding leg may provide a controllable electrical ground between the PCB and the enclosure. Various other methods and apparatuses are also disclosed.
