Abstract: An autonomous mobile device (AMD) moves around a physical space while performing tasks. The AMD may have sensors with fields of view (FOVs) that are forward-facing. As the AMD moves forward, a safe region is determined based on data from those forward-facing sensors. The safe region describes a geographical area clear of obstacles during recent travel. Before moving outside of the current FOV, the AMD determines whether a move outside of the current FOV keeps the AMD within the safe region. For example, if a path that is outside the current FOV would result in the AMD moving outside the safe region, the AMD modifies the path until poses associated with the path result in the AMD staying within the safe region. The resulting safe path may then be used by the AMD to safely move outside the current FOV.

Abstract: A method for inter-coding video in which encoder and decoder memory requirements associated with storage of motion information related to collocated coding units is reduced. In the method motion information related to only a single or reduced set of collocated coding unit(s) may be stored at the encoder and decoder. In operation, if the encoder determines that motion information for a current coding unit should replace a currently stored motion information for currently stored motion information for the collocated coding unit, then the encoder can replace the motion information at the encoder and transmit an indicator with the current coding unit to signal to the decoder that currently stored motion information currently should be updated or replaced with the motion information associated with the current coding unit.

Abstract: An exemplary method for visual media processing includes performing a conversion between a current video block of a visual media data and a bitstream representation of the visual media data in accordance with a conditional signaling rule. The current video block is disabled from using an intra sub-block partitioning (ISP) split mode which divides the current video block into sub-blocks depending on dimensions of the current video block. In case that the conversion is associated with disabling use of the ISP split mode, the conditional signaling rule specifies selectively including in the bitstream representation a first syntax element indicating that a luma component of a sub-block of the current video block includes non-zero coefficient values. The selectively including is based at least on one or more other syntax elements having non-zero coefficient values of one or more previous sub-blocks included in the bitstream representation.

Abstract: The present disclosure discloses a data receiving apparatus and a data receiving method having blind deconvolution mechanism. A descrambling circuit descrambles received data according to an antenna assumption and N data position assumptions within a transmission period to generate N groups of soft-bit data. A soft-bit processing circuit retrieves bit position data to determine non-variable bit positions and variable bit positions. N circular buffers of a storage circuit store and superimpose the N groups of soft-bit data corresponding to N data position assumptions in a circular manner to generate N groups of superimposed results and keep the data corresponding to the non-variable bit positions. A post-processing circuit performs de-interleaving and decoding on the N groups of superimposed results to generate N groups of decoded results to perform redundancy check thereon. When one decoded results passes the redundancy check, the soft-bit processing circuit stops performing the blind deconvolution process.
