Abstract: Various implementations detect object movement during object scanning and alter scanning processes accordingly. For example, when movement of the object being scanned is detected, the device may stop scanning (e.g., capturing shots) and wait for the object to stop moving. When the object stops moving, the device may re-localize the scanned model with the new position of the object and continue with the scanning processes.

Abstract: In one aspect, a playback device is configured to: (i) after receiving an indication that the presence of one or more first wireless networks is detected, transition from a second power state to a first power state; (ii) update, while in the first power state, a state variable from a first value indicating that a connection via at least one of one or more second wireless networks should be established to a second value indicating that a connection via at least one of the one or more first wireless networks should be established; and (iii) after updating the state variable, enter the second power state.

Abstract: Various implementations generate geometric representations based on depth information detected in physical environments. For example, an example process may include acquiring sensor data of an object in a physical environment, the sensor data including images of a physical environment captured via a camera on the device. The process may further include generating a three-dimensional (3D) voxel representation of the object based on the images. The process may further include determining signed distance values (SDVs) of voxel corners for voxels of the 3D voxel representation, the SDVs representing distances to surfaces of the object; determining occupancy data for the voxels of the 3D voxel representation, the occupancy data corresponding to whether the voxels are occupied by the object. The process may further include generating a 3D mesh of the object based on the SDVs of the voxel corners and the occupancy data for the 3D voxel representation.

Abstract: Various implementations disclosed herein provide feedback to a user during object scanning based on how well sensor data of the scanned object has been captured. During object scanning a user may move an electronic device with sensors (e.g., cameras, depth sensors, etc.) around an object to capture sensor data for use in generating a final 3D model of the object. Live feedback during the scanning process is enabled by assessing how well the captured sensor data represents different portions of the object. In some implementations, a 3D model is generated, updated, and assessed based on the sensor data live during the scanning process. This live 3D model may be coarser (i.e., having fewer details) than the final 3D model.

Abstract: According to at least one aspect, power management techniques are disclosed that may reduce the power consumption of devices, such as those devices in media playback systems, without introducing a noticeable lag between a user issuing a command and the device processing the command. In some embodiments, the device may put to sleep (including turn off) electronic components that are only used for specific commands. In these embodiments, the devices may identify periods where the specific commands are likely to be invoked and, in response to identifying such a period, wake-up the electronic components. As a result, the power consumption of the device may be substantially reduced because various electronic components may be put to sleep instead of remaining idle in an awake state.
