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: Embodiments of the present disclosure relate to power saving mechanisms for a wearable camera device. The camera device comprises an image sensor and lens assembly in an optical series with the image sensor. At a first orientation of the camera device, an offset is between a center axis of the image sensor and an optical axis of the lens assembly. At a second orientation of the camera device, at least one of the image sensor and the lens assembly sag due to gravity such that the center axis and the optical axis substantially overlap while the camera device is in a neutral state. The lens assembly and the image sensor can further allow a dynamic amount of sag relative to each other.

Abstract: A camera device for integration into an electronic wearable device. The camera device includes a lens assembly, an image sensor, a first actuator assembly, and a second actuator assembly. The first actuator assembly translates the lens assembly over a first range along an optical axis, wherein power consumed by the first actuator assembly increases with a distance the lens assembly is actuated along the optical axis from a neutral position of the lens assembly. The second actuator assembly translates the image sensor over a second range along the optical axis, wherein the second range is smaller than the first range. A method of packaging the camera device is further presented where a molded plastic layer is sandwiched between a first high density interconnect (HDI) tape substrate and a second HDI tape substrate. The molded plastic layer includes vias to interconnect electrodes of the first and second HDI tape substrates.
