Title: A motor drive and control circuit for electric power steering
Inventor: NATHANAEL RICE
IPC: H02P5/74
Filed: 2017-12-06
Abstract: A electric circuit 100 has lanes 102a,102b,104a,104b for several phases of motor windings driven by motor drive bridges with networks of drive stage switches that selectively connect each phase of the lanes to supply voltages and supply lane grounds, with control circuits 110a,110b powered by isolated lane power supplies 108a,108b with floating grounds, and that exchange digital control signals to monitor the other lanes with the floating grounds and supply lane grounds connected together through a potential divider network that holds the floating grounds at a potential that is between the potential of the supply lane grounds for the lanes. The circuit can be used for electric power assisted vehicle steering. Thus the control circuits can exchange signals despite noise or voltage spikes. Cross lane power winding (230a,230b, fig 2) can be provided.

Title: Communication system
Inventor: TAO GUO
IPC: H04W16/10
Filed: 2018-05-31
Abstract: A communication system is disclosed in which communication resources, such as physical resource blocks (PRBs), are dynamically partitioned into slices, each slice having at least one associated network-level performance requirement, which may be associated with service categories such as Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communications (uRLLC) and Massive Machine Type Communications (mMTC). A network-level performance requirement is translated 90 into cell-level resource requirements for determining, based on the cell-level resource requirements, whether to admit a slice instance 91. When the slice instance is admitted, information identifying the cell-level resource requirements for the slice instance is provided to a scheduler function 93. The cell-level resource requirements for a given slice instance may be used to determine an associated packet delivery deadline and entitled resource amount before deadline. The scheduler function 94 allocates communication resources, e.g. PRBs, to each admitted slice based on an earliest‑deadline first method.

Title: Fuel pump
Inventor: JAMES T D MCHATTIE
IPC: F02M59/44
Filed: 2018-06-13
Abstract: A plunger 50 for a pump assembly for delivering pressurised fuel to a common rail fuel volume is disclosed. The piston 50 comprises a cap 54 and body 52 portion positioned in coaxial alignment with concentric bores (84,68, Figure 3) in their adjacent faces. A flexible connector 58 if fixedly engaged in the bores and is displaceable during movement of the plunger to allow axial movement of the cap with respect to the body. A conical interface 56 between the cap and body converts the axial movement of the plunger cap in to a radial expansion to reduce the clearance between the plunger and the pump cylinder bore. The plunger mitigates against the diameter of the piston reducing during compression and the associated fuel leakage, loss of volumetric efficiency, energy loss and increased C02 emissions. A pump for delivering fuel to a common rail is also disclosed.
