Title: Energy generation
Inventor: FRANK WOODBINE
IPC: G21J3/00
Filed: 2016-01-12
Abstract: Apparatus for generating energy suitable for use in an electrical power station. The apparatus comprises a quench chamber, the quench chamber containing a quench fluid, the quench chamber having a fuel inlet and an outlet in fluid communication with at least one turbine of the power station, a target located within the quench chamber, and a propulsion means operable to propel a projectile towards the target. The projectile comprises a shaped charge comprising a charge liner having a front portion and a rear portion, an explosive material located adjacent to at least the rear portion of the charge liner and a detonator operable to detonate the explosive material. In use, the propulsion means propels the projectile through the fuel inlet towards the target and, before the projectile reaches the target, the detonator detonates the explosive material generating a jet of particles which impacts the target, thereby releasing energy, which heats the quench fluid causing a gas to be released through the outlet, which gas then drives the at least one turbine. Also claimed are the projectile per se and a method of operating the apparatus. In a preferred embodiment the shaped charge also includes a fusion fuel element which potentially ignites to cause nuclear fusion within the chamber.

Abstract: A wireless system using cells (100, 110, 120, 130) to provide wireless access of users (U) to services, having a first base station (10) installed on board a public transportation vehicle such as a bus (B) to provide a moving cell, and a second base station (12) installed at a stop (BSI BS2) at which users enter or leave the vehicle, to provide a fixed cell. A central controller (20) is further provided for guiding handovers of users entering or leaving the vehicle (8). The first and second base stations (10, 12) are arranged to provide data concerning users to the central controller (20), and the central controller, over many journeys of the vehicle (B), gathers profile data of users (U) based on the data provided by the base stations. As the vehicle (B) approaches a next stop (882), the central controller (20) makes predictions about which users are likely to enter and leave the vehicle at the stop, and based on the predictions, provides guidance to the first and second base stations (10, 12) for performing handovers of the users and/or for resource allocation following handover. Independent claims include a central controller and a method of controlling a wireless system.

Title: Method, device, and computer program for improving synchronization of clocks in devices linked according to a daisy-chain topology
Inventor: ROMAIN GUIGNARD
IPC: H04J3/06
Filed: 2016-12-06
Abstract: The embodiments relate to the precision time protocol (PTP, IEEE 1588-2008) and specifically to transparent clocks daisy chained together in the path between master and slave clocks. The invention proposes calculating residence times (the period that a time-stamped message spends in the node before being forwarded) using fully synchronised (clock rate and absolute time) ordinary clocks, rather than syntonised (clock rate only) clocks as per the standard. Whilst the clock is uncalibrated/unsynchronised 508, the invention proposes using theoretical residence times 510 (historical average, calculated from traffic load) rather than measured ones. Following calibration/synchronisation residence times measured by the clock 520 are used 522, except where they exceed predetermined maxima/minima 521 whereupon theoretical values are substituted 524.

Patent GB-2569203-A (GB)
Title: Improvements in and relating to remote authentication devices
Inventor: MARK TIMOTHY BRYANT
IPC: H04L29/06
Filed: 2018-05-23
Abstract: An authentication device that comprises a microprocessor 40, an EEPROM 20, a register 50 and a display 60. The EEPROM is used to store a one-time pad (OTP) from which a plurality of bits are drawn to form a key of random length. The microprocessor retrieves a start position from the register and retrieves from the OTP a bit sequence that forms a key of the required length. The microprocessor hashes the key and concatenates it with the start position and the key length to generate an authentication code. The authentication code is transmitted to a remote device which contains the same one-time pad. The remote device generates its own authentication code and compares it to that which it received in order to authenticate it. Each time a key is drawn from the OTP a different sequence of bits is obtained i.e. keys are never reused. The previous key may be erased from the OTP so that previous communications remain secure even if the device becomes compromised. The authentication device may be included in a smart card such as a credit card.
