  • Publication number: 20240005565
    Abstract: Methods and devices for encoding a point cloud. A bit sequence signaling an occupancy pattern for sub-volumes of a volume is coded using binary entropy coding. Contexts may be based on neighbour configuration and a partial sequence of previously-coded bits of the bit sequence. A determination is made as to whether to apply a context reduction operation and, if so, the operation reduces the number of available contexts. Example context reduction operations include reducing neighbour configurations based on shielding by sub-volumes associated with previously-coded bits, special handling for empty neighbour configurations, and statistics-based context consolidation.

  • Patent number: 11847606
    Abstract: A system and method for providing verification of tracking and monitoring devices with cargo transportation units is provided. The track and monitoring device is mounted to the cargo transportation unit to provide location tracking and security functions. The association process is typical a manual process by a technician of identifying container visual identifiers to the installed tracking and monitoring unit. Errors in the association process can occur during installation and repairs. The association between tracking and monitoring devices and their respective cargo transportation unit is verified by receiving images from one tracking and monitoring device at a server and verifying the cargo transportation unit identifier is associated with another tracking and monitoring device.
