    Abstract: An example method of video decoding includes receiving a video bitstream comprising a plurality of blocks, including a current block. The method also includes performing a first partitioning of the current block such that the current block is partitioned into a first rectangular partition and an L-shaped partition, where the first rectangular partition has a same aspect ratio as the current block, and after performing the first partitioning, partitioning the L-shaped partition into a plurality of second rectangular partitions, where the plurality of second rectangular partitions includes partitions having different aspect ratios. The method further includes decoding the current block according to the first rectangular partition and the plurality of second rectangular partitions.

    Abstract: A cleaning pad for an autonomous cleaning robot evenly wets and collects debris for cleaning operations. The pad includes a core of absorbent layers for absorbing liquid through capillary action and for distributing the liquid within the cleaning pad. The pad includes a wrap layer around the core, the wrap layer comprising a fibrous layer that is flexible and absorbent, the fibrous layer configured to absorb liquid through capillary action and transfer the liquid to the core. The pad includes one or more transition regions spanning a cleaning width of the cleaning pad, the one or more transition regions dividing the cleaning pad into at least two segments. The forward positioned segment of the pad, of the at least two segments of the pad, has a lesser thickness compared to a thickness of an aft positioned segment of the at least two segments.

    Abstract: A cleaning roller mountable to a cleaning robot includes an elongate shaft extending from a first end portion to a second end portion along an axis of rotation. The first and second end portions are mountable to the cleaning robot for rotating about the axis of rotation. The cleaning roller further includes a core affixed around the shaft and having outer end portions positioned along the elongate shaft and proximate the first and second end portions. The core tapers from proximate the first end portion of the shaft toward a center of the shaft. The cleaning roller further includes a sheath affixed to the core and extending beyond the outer end portions of the core. The sheath includes a first half and a second half each tapering toward the center of the shaft.

    Abstract: The present disclosure provides a cleaning assembly including a cleaning performing device. The cleaning performing device includes a cleaning module configured to clean a surface and a cleaning driving module configured to drive the cleaning module to move relative to the surface, a driving device configured to drive the cleaning performing device to be lifted or lowered, and a constraining structure configured to constrain a lifting or lowering trajectory of the cleaning performing device. The present disclosure further provides a cleaning apparatus. The cleaning performing device can be lifted or lowered according to an actual need, such that improves an adaptability of the cleaning apparatus. Further, the lifting or lowering trajectory of the cleaning performing device can be constrained by the constraining structure, such that improves a stability of the cleaning apparatus during moving up and down.
