Abstract: Methods and wearable devices for optimizing power consumption using sensor-based position and use determinations are described here. One example method is performed at a device that includes a first sensor configured to operate with a first power consumption rate and a second sensor configured to operate with a second power consumption rate. The method includes, while a component associated with the second sensor is in an inactive state, receiving first sensor data, and determining whether the first sensor data indicates movement of the device. The method also includes, when movement of the device is indicated, operating the second sensor in an active state. The method further includes, after activating the second sensor, when second sensor data from the second sensor indicates that the device has been placed on a user’s body, continuing to operate the second sensor in the active state.

Abstract: The disclosed mobile electronic device may include a display, an enclosure supporting the display and comprising a conductive portion, a ground plane positioned within the enclosure, wherein a gap defined between the conductive portion of the enclosure and the ground plane forms a slot antenna that is configured to radiate first electromagnetic signals through a portion of the display, the first electromagnetic signals radiated by the slot antenna being used for wireless communication in a first wireless communication band, and a patch antenna, comprising a substantially planar conductor, that is configured to radiate second electromagnetic signals, the second electromagnetic signals radiated by the patch antenna being used for wireless communication in a second wireless communication band different from the first wireless communication band. Various other related methods and systems are also disclosed.

Abstract: Systems may include a watch band, a watch body including at least one image sensor configured to capture a wide-angle image, a coupling mechanism configured to detachably couple the watch body to the watch band, and at least one biometric sensor on at least one of the watch band or the watch body. Various other related methods and systems.
