Title: Random access repeater, relay system and relay method therefor
Inventor: ZHUOQUN LI
IPC: H04W52/02
Filed: 2016-08-24
Abstract: Disclosed are a random access repeater, a relay system and a relay method therefor. The method comprises: a repeater sending a broadcast signal; a terminal receiving the broadcast signal; the terminal sending, in a random access time window of the repeater, a message to the repeater; and the repeater sending a confirmation message to the terminal after successfully receiving the message and successfully forwarding same. The coverage range expansion and large-scale networking of a low rate wireless communication network are supported by a wireless repeater in the present application. A repeater does not need to schedule the communication of the terminal, and only needs to be dormant periodically according to a certain rule. A large number of terminals can automatically adjust the sending time of an uplink message, such as an event trigger signal, according to a dormant period of the repeater, so as to ensure that the message can be received and forwarded by the repeater, and is finally received by a base station.

Title: System and method for aircraft flight planning
Inventor: ADAM DURANT
IPC: G08G5/00
Filed: 2018-09-11
Abstract: An aircraft flight planning system has a measure of an atmospheric contaminant. It receives an aircraft flight plan and calculates a corresponding estimate of atmospheric contaminant risk using the measure based on a location, pressure or altitude, trajectory and time extracted from the flight plan. It outputs an indication of the estimate, e.g. an index of risk of atmospheric contamination on the flight, a recommendation to modify the flight plan to mitigate contaminant exposure or an indication of portions of the flight where exposure exceeds a threshold. A second atmospheric contaminant risk estimate may be calculated for an altered flight plan and compared to the first estimate. The calculation may use further variables related to engine or aircraft control, loading or operation, engine or aircraft model or type, weather, temperatures, speeds, altitudes, mass or fuel flow rates, vibration, inspection results or wear estimates. It may involve spatial or temporal uncertainty calculation or a statistical, regression, machine learning or Monte Carlo model. The contaminant may be ice crystals, dust, organic particles, volcanic ash, salt, sulphur dioxide or sulphate ions and the risk may be a probability of ice crystal presence or an exposure index indicating an amount of contaminant passed through aircraft engines.

Title: Management of a blockchain
Inventor: MATTEO SIGNORINI
IPC: H04L9/32
Filed: 2019-12-16
Abstract: A method and apparatus for managing a blockchain in a blockchain network such that the blockchain does not grow to a large size wherein a limit for the number of blocks in the blockchain is defined S1 and previous blocks in the blockchain are overwritten when creating new blocks if this limit has been reached S3. The index of a created block and the index of an overwritten previous block may be a congruent modulo of said limit of blocks. The blockchain may also improve privacy as old blocks are overwritten and therefore the transactions contained therein are lost and cannot be analysed though transaction flow analysis. The blockchain may be used to host smart contracts or implement cryptocurrency. Blockchain state information may be stored in a blockchain ledger. The blockchain may be public/permissionless or private/permissioned. The blockchain may be a ‘backward-secret’ chain wherein the ‘block-high’ representing the number of blocks is transformed by a modulo operation.
