Patent number: 11979499Abstract: Embodiments of the present disclosure provides protocols, methods and systems which provides advantages such as the resistance of centralisation of mining on a blockchain network, preferably a Proof-of-Work blockchain. A method in accordance with an embodiment may comprise generating a plurality of non-parallelisable challenges (or “puzzles”) and allocating one of said plurality of challenges to each miner on the network. The miner uses an inherently sequential (non-parallelisable) algorithm to find a solution to his allocated challenge. The challenges are generated by a committee of nodes, and a new set of challenges is generated for each block.Type: GrantFiled: April 29, 2020Date of Patent: May 7, 2024Assignee: nChain Licensing AGInventors: Craig Steven Wright, John Fletcher, Alexander Tennyson MacKay

Publication number: 20240126406Abstract: Aspects of the present disclosure are directed to an artificial reality system orchestrating interactions between virtual object “augments.” The orchestration can include linking, which can be forming two or more augments into a combination, embedding an augment within an existing combination, or triggering an action mapped to the linking of those augments. Another type of orchestration can include extracting, which can refer to taking an augment out of an existing combination, either by removing it from the combination or copying the augment to leave a version in the combination and having another version outside the combination.Type: ApplicationFiled: December 14, 2023Publication date: April 18, 2024Inventors: Michal HLAVAC, Benjamin Taylor WINN, Wai Leong CHAK, Jasper STEVENS, Alexander Michael LOUIE

Publication number: 20240109725Abstract: A material handling system includes storage locations disposed in racks and a track having a vertical section adjacent one of the racks. A plurality of material handling vehicles are provided, each including a horizontal drive for driving the vehicle horizontally, a vertical drive for driving the vehicle vertically, and a mechanism for transferring items onto or off the vehicle. A vehicle accessory has an opening configured to cooperate with the vehicles. A central controller may be programmed to provide control signals to determine whether a mode of operation to perform an inventory management task is a first mode of operation or a second mode of operation. The central controller may then control the operation of one of the vehicles to operate without the vehicle accessory in a first mode or with the accessory in the second mode.Type: ApplicationFiled: October 18, 2023Publication date: April 4, 2024Inventors: Alexander Stevens, Joseph Valinsky
