Title: Attesting to membership of a set
Inventor: STEVEN PATRICK COUGHLAN
IPC: H04L9/40
Filed: 2022-02-15
Abstract: A method of a challenger challenging a challengee to publicly commit to a set of data items based on a hash/Merkle tree whose leaves designate the data items. A challenge transaction 152Ch is recorded on a blockchain. This transaction comprises code 900 which, when run on a node of a blockchain network in response to an attempt to validate a candidate transaction 152Can, receives and verifies a signature 952 of the challengee from the candidate transaction, and determines whether the candidate transaction provides a solution to a hash puzzle 902, the required solution comprising the root 953 of the hash tree and additional information 954 (e.g. a non-root node of the hash tree or a token) identifiable only to a restricted set of parties, including the challenger and the challengee. On passing these tests the candidate transaction is validated for recordal on the blockchain, thereby redeeming a reward for the challengee. The identity of the additional piece of information being known to a limited set of parties, reduces the chance of a malicious party claiming the reward using a replay attack. The data items may be unspent transaction outputs (UTXO).

Patent GB-2614800-A (GB)
Title: Motor drive
Inventor: ANDREW JOHN WILKS
IPC: H02P27/16
Filed: 2022-11-17
Abstract: A synchronous motor is driven by generating a drive signal comprising a non-continuous series of full cycle pulses of a specified time period T. The timing of the full cycle pulses corresponds to a desired motor rotation characteristic. Each full cycle pulse may be substantially sinusoidal. Each full cycle pulse may start and end at a zero crossing. At least two pulses in the drive signal may be separated by a period of substantially zero value. Different motor drive signals may be generated in response to different desired motor rotation characteristics. The motor rotation characteristic may be a profile of rotational speed and/or position which varies over time. The synchronous motor may be a single phase or three phase motor. The timing of the full cycle pulses may be determined using counter circuitry or a look up table and may be dependent on the synchronous speed of the motor. The arrangement may be suitable for use in applications such as clocks and other time critical drive mechanisms.
