Patent GB-2583100-A (GB)
Title: Path profile analysis
Inventor: CRAIG INNES STEWART
IPC: F41G9/00
Filed: 2019-04-16
Abstract: The invention provides storage means for storing transmission data relating to an entity, e.g. a tank; a controller configured to calculate a propagation profile for the entity based on at least the transmission data; and a display for displaying the propagation profile. In an embodiment, the invention reduces the probability of detection by an adversary of a military asset, e.g. a vehicle, tank or aircraft, as a result of electromagnetic emissions, by i) creating a vehicle profile using stored data, ii) creating an adversary profile using stored data, and iii) determining, based on the extent of overlap or predicted overlap between the profiles actions that could be performed to minimise the likelihood of the detection of the vehicle. The determined action may minimise the vehicle’s EM or audible signature, or move the vehicle to positions where an adversary is less likely to detect noise or emissions.

Title: A method of determining an angular offset of a position sensor
Inventor: DAVID MOULE
IPC: H02P6/16
Filed: 2019-04-16
Abstract: An offset between an angular position indicated by a rotary position sensor assembly, secured directly or indirectly to the rotor 22 of a multi-phase U, V, W permanent magnet AC motor 20, and an actual electrical position of the motor rotor is determined. A voltage vector aligned with a known angular position of the motor is applied to the motor, the rotor moves to a location in which the vector, when considered in the dq frame of reference, is centred on the d-axis (α+jβ). The angular position of the rotor indicated by the position sensor is measured, and the offset is determined from the difference between the measured angular position and the known actual position of the vector. The offset may be determined for multiple vectors at different known positions. A dither may be applied to the vector that causes the vector to move backwards and forwards across the zero degrees position with the output of the position sensor measured over time and a mean position value used. The arrangement may be applied to a position sensor forming part of an electromechanical actuator for use in a hydraulic braking circuit of a vehicle.

Title: Systems and methods for providing block chain-based multifactor personal identity vertification
Inventor: MARCUS ANDRADE
IPC: H04L29/06
Filed: 2016-03-29
Abstract: Block chain-based multifactor personal identity verification. A first and second verification address (i.e. an address indicating a particular location on a blockchain) may be assigned to an individual having a previously verified identity, an identifier for the individual and unique data e.g. biometric data of the individual is stored in the blockchain at the assigned first verification address and second unique data e.g. biometric data is stored at the second verification address. A request to verify an individual’s identity is received from a client-side device, the request containing a received identifier(s) and received unique data e.g. biometric data, the request indicating the associated blockchain verification address(es). The unique data e.g. biometric data recorded in the blockchain are retrieved from the specific address(es) and upon successful matching of the supplied information and matching associated private keys, identity verification is successful, which may involve signing a verification possibly using the associated private key related to the verification address. Users, different to the individual, have different access to the stored data based on their respective private keys. Users may also request addition or deletion of verification addresses assigned to the individual so long as one verification address is assigned to the given individual.

Title: Data processing method and apparatus
Inventor: EDWARD HAWKE
IPC: G06T7/73
Filed: 2019-12-13
Abstract: Advances in image processing technology have made it possible to capture and analyse images of sporting events in higher volumes and in more detail than ever before. One example of this is video assistance referee (VAR) technology which allows events in a soccer game such as a foul or goal to be reviewed using images of the event captured from different angles, another is using one or more cameras to track the participants in a race e.g. horse or motor racing. However there remains a desire for this technology to be improved and for it to be used in new ways. The ability to map objects on the pitch with objects in an image captured by one or more rotatable cameras is desirable in applications such as VAR but if there are many such cameras it is time consuming and labour intensive for the VAR referee to review footage from all the cameras and it is therefore desirable for objects on the pitch involved in an event to be mapped to images of said event captured by one or more rotatable cameras and for those images to be indicated to the referee. A data processing means obtains information identifying a position of an object in a scene at a time during the sporting event e.g. a football match together with an image of the scene captured at the time during the sporting event. The position of the object in the scene is then projected onto an image plane of the image and information based on the projection is output. The images of the pitch and players may be presented on a touch screen whereon the position of the players and the ball are indicated, and individual images may be selected by a user. The images presented are a subset of those available and are selected on the basis of the best mapping for objects in the scene for the event being reviewed. Play, rewind and fast forward functions may be included for reviewing the clips.

Title: Force sensing systems
Inventor: GAVIN MCVEIGH
IPC: H03K17/96
Filed: 2020-01-09
Abstract: A compensation circuit 420 at least partially cancels the offset voltage in an output signal of a force sensor 410. The compensation circuit 420 comprises a voltage divider 422 which receives a bias voltage Vbias that has also been supplied to force sensor 410. The voltage divider outputs a control voltage Vcont, derived from Vbias, and the component mismatch ratio of the voltage divider circuitry is adjustable to correspond to a component mismatch ratio of the force sensor. A current generator 424 receives Vcont and generates a compensation current Icomp. Amplifier circuitry 426 receives the differential signal output by the force sensor and Icomp and outputs a compensated differential output signal in which the offset voltage is at least partially reduced. The voltage divider may have an adjustable ratio of Vcont to Vbias corresponding to a ratio of a quiescent different output voltage of the force sensor to Vbias. A ratio of resistances of the voltage divider circuitry may be adjustable to correspond to a ratio of resistances of the force sensors. Also provided are a force sensor circuit and force sensor system corresponding to the disclosed compensation circuit.

Title: Data compression
Inventor: RUNE ERLEND JENSEN
IPC: G06F9/50
Filed: 2018-08-09
Abstract: Data to be compressed consists of multiple different types of data. One algorithm is selected to compress the data based on the data types and a desired compression rate or ratio. When compressing the data, more computing resources are allocated to the compression of the data types that are more efficiently compressed by the selected algorithm than those that are less efficiently compressed. Worker threads may be used to compress the data. The throughput of the threads may be adjusted based on performance metrics. The compression efficiency may be estimated using a model of the compression performance of the algorithms. Part of the data may be compressed, and part of the data may be left uncompressed. The compression may take part in a storage system or in a plug-in to a storage system.
