Title: Transaction system and method of operation thereof
Inventor: TOBY WILLIAM SIMPSON
IPC: G06Q30/06
Filed: 2018-08-17
Abstract: A blockchain transaction system uses a directed acyclic graph (DAG), or acyclic digraph, to define relationships between blockchain blocks 1A, 1B, 1C. The distributed blockchain ledger stores references to the start and end of the DAG, and to a smart contract. The smart contract defines a problem to be solved and a consideration or incentive to be exchanged once proof of work completed is provided. Machine-readable elements of the smart contract define at least a data specification, a contract body defining the problem, an initial mining algorithm, or an objective function for scoring proposed solutions. The DAG comprises proposed solutions 2B to the problem posed in the smart contract. Proof-of-stake (PoS) may be used as a consensus mechanism to verify updated entries made in the blockchain ledger. The transaction system may terminate sub-optimal proposed solutions. The smart contract may dynamically change the address of a party to the smart contract. The consideration or incentive may comprise an award of: fiat currency; digital currency; value tokens; access to data, information, bandwidth or ports; processor usage; processing time; heat generated by a computer; or cooling energy used by a computer.

Title: Dense 3-D occupancy mapping
Inventor: JUAN TARRIO
IPC: G01C21/32
Filed: 2021-01-29
Abstract: A computer-implemented method for building and updating a 3-D occupancy map of occupied and unoccupied spaces in a 3-D environment. Each sub-map comprises occupancy information within its respective volumetric region, including occupancy indications for a plurality of voxels. Each occupancy indication may indicate a likelihood that the respective voxel is occupied or unoccupied. Updating the at least one sub-map based on the 2-D depth image and associated pose estimate may comprise updating the occupancy information — in particular, updating the occupancy indications — based on the 2-D depth image and associated pose estimate. A single depth image may contain depth information that is relevant to multiple sub-maps. The method therefore updates multiple sub-maps based on depth information from one frame (for example, the most recently obtained frame). In some embodiments, all sub-maps in a list of active sub-maps may be updated with depth information from each 2-D depth image. A mobile device for building and updating the occupancy map may be a handheld device, robot, or a vehicle. The vehicle may be an unmanned and/or autonomous vehicle, a land vehicle, an aerial vehicle, a marine vehicle or a submarine vehicle.

Title: A method to map dynamically drawn augmented reality (AR) scribbles using recognition of discrete spatial anchor(s)
Inventor: Thomas William Judd
IPC: G06T19/00
Filed: 2022-02-23
Abstract: An augmented reality or mixed reality system in which a field device 102 captures video, receives scribble pattern annotation data 193 from a remote expert device 170, identifies an anchor and a plane in the video feed based on a fiducial marker 194 detected in the images of the captured video, maps the scribble pen annotation data onto the video feed data according to the anchor and plane to create a continuous AR video feed, and sends this continuous AR feed to the remote expert device for display. This is said to reduce latency and bandwidth usage when communicating annotated video for AR as the expert device sends only scribble pattern or annotation data coordinated rather than the full video comprising annotation. Preferably the scribble data is only sent from the expert device at a send command determined automatically or via user control. As the AR annotations are included in the continuous video returned to the expert device, motion in the video and registration of the annotations in relation to an anchor only need occur at the field device. The expert device may send a clear command to remove previous annotations.
