Abstract: Various implementations provide 3D representations of objects. Such representations may be based on 3D point cloud and/or 2D image inputs that are obtained based on sensor data, e.g., images, depth data, motion data, etc. 3D point cloud input may be used for part segmentation and/or to determine position and/or orientation of object parts, e.g., generating 3D bounding boxes representing the sizes, positions, and orientations, of object parts. 2D image input may be used for part attribute recognition, e.g., to determine whether a chair legs part has a particular type such as star-shaped, straight down, crossed-shaped, etc. Part attributes may be used to produce a relatively simple and relatively accurate representation of the shape of each part within a respective area, e.g., within a bounding box determined for each part using the 3D point cloud input.

Abstract: Implementations described and claimed herein provide systems and methods for supplying voltage to a load and battery. In one implementation, a first regulated DC-to-DC converter is electrically connected to a first energy source to down convert a first voltage supplied by the first energy source. A load is electrically connected to the first regulated DC-to-DC converter to receive the down converted first voltage. A second regulated DC-to-DC converter is electrically connected to the first regulated DC-to-DC converter to regulate the down converted first voltage to a second voltage. A second power source is electrically connected to the second regulated DC-to-DC converter to charge the second power source using the second voltage, and the second power source is switchably connectable to the load.
