Title: Controlled interruptions to wireless signalling
Inventor: PATRICK DAVID COOPER
IPC: H04W52/02
Filed: 2017-09-28
Abstract: To mitigate the effects of intentional interruptions to a data signal communication, the transmitting or receiving device determines when a portion of the signal has been successfully transmitted or received then generates a transmission interruption signal. In response to this signal, a maintenance operation is performed which would potentially interrupt reception of the data signal. The maintenance operation may relate to beamforming, a change of transmission channel, or entering a sleep mode of operation. The operation may only be performed if it can be completed before the next portion of data is due. In one aspect of the invention, the transmission interruption signal is only generated if the expected level of disruption to a user caused by the maintenance operation not being performed is greater than that of the next portion of data not being received on time. The data portion may be a frame of image data or a quantity sufficient to fill a buffer. The system may be used to prevent disruptive visual artefacts when using virtual-reality headsets.

IPC: H02G3/22
Filed: 2018-09-26
Abstract: An umbilical termination assembly for terminating a cable or umbilical comprises a plurality of umbilical elements extending from an umbilical which pass through a bulkhead plate 3. A seated ball element 6 has a spherical body 6a through which an umbilical element, such as a steel tube 2, passes. The ball element may be seated in a cup member 8 which allows the ball element to rotate through a large range of angles allowing it to be aligned with the umbilical element without the umbilical element needing to be manipulated or forced into position. The umbilical element can then be attached to the ball element which is supported by the cup member on the bulkhead. This allows the axial tension in the umbilical element to be transferred to the bulkhead. The ball element may have one 6b or more (6c, Fig 3) sleeve portions. The cup member may screw in (21, Fig 4) to allow the tension on the umbilical to be adjusted. An isolation bush (14, Fig 6) may insulate the cup from the plate to prevent electrochemical reactions.

Title: Conductor etching for producing thin-film transistor devices
Inventor: JAN JONGMAN
IPC: H01L51/40
Filed: 2020-01-24
Abstract: A method for producing thin-film transistor devices comprises forming an organic polymer insulator 8 over a first conductor pattern 4 defining a first level of conductors, forming a protection layer 10 over the organic polymer insulator and forming a conductive layer 12 over the protection layer.

Title: Torque distribution strategies for hybrid vehicles
Inventor: LEE ADCOCK
IPC: B60W20/15
Filed: 2020-04-21
Abstract: A method and control system for a vehicle comprising an internal combustion engine (202; fig. 2) providing torque to a first axle (222a,b; fig. 2) and an electric machine (e.g. electric motor, 212; fig. 2) providing torque to a second axle (224a,b; fig. 2). The method includes outputting 402 an engine torque request and an electric machine torque request; determining 424 that a trigger condition is satisfied (e.g. driver selection of terrain mode 420 or detection of low traction surface or wheel slip 422); and hence controlling 426 determination of the electric machine torque request such that the ratio of torque values output to the wheels at the two axles (second ratio, dependent upon relative wheel torque response capabilities of the engine and electric machine) is inhibited from deviating from the ratio between the torque requests (first ratio, dependent on a required torque split between axles). E.g. when there is low traction, the same front-rear axle torque split is output to the wheels as is requested, prioritising maintaining the torque split instead of attempting to meet driver requested total torque demand by using compensation torque from the electric machine for engine torque shortfall 406.
