Abstract: Systems and techniques are provided for implementing LiDAR point cloud stitching. An example method includes determining a visibility grid that is based on a plurality of measurements from a first LiDAR device, wherein the visibility grid includes a plurality of range values corresponding to a field of view of the first LiDAR device; identifying, based on the visibility grid, at least one occluded region in the field of view; and modifying a point cloud that is based on the plurality of measurements to include additional points corresponding to one or more measurements obtained from a second LiDAR device, wherein the one or more measurements correspond to the at least one occluded region.

Abstract: A user can associate a digital asset corresponding to a value with a transaction device to be used by another user. For example, a first user can load a digital asset corresponding to a cryptocurrency amount onto a transaction device, where the first user then provides the transaction device to a second user. The second user can utilize the cryptocurrency amount on the transaction device to conduct a transaction. The generation and use of digital assets can be managed using ledgers that store data in the form of block chains.

Abstract: A custom moldable seating product includes a seat having a seat bottom and a seat back, and a moldable element for being carried by the seat. The moldable element is transformable from an initially flexible unactivated state to an activated state, such that the moldable element conforms to a seat occupant positioned on the seat. The moldable element may include a first component contained in a first compartment and a second component contained in a second compartment. The first and second compartments may be contained in an initially flexible enclosure. The first and second compartments may be ruptured to allow the first and second components to mix within the enclosure. The reaction of the first and second components create an expandable foam that conforms to a body part of a seat occupant positioned on the seat.
