Title: A method of manufacture of a gate drive circuit and a gate drive circuit
Inventor: GEORGE YOUNG
IPC: H05K1/16

Abstract: A high side driver suitable for providing a drive signal to a gate of a semiconductor switch comprises a transformer, a printed circuit board (PCB) substrate (Fig.4, 120), driver circuitry, and switch contacts including at least a gate contact for connecting to the gate of a high side driver switch. The transformer, which includes primary and secondary side windings and a magnetic core 128, typically provides isolation between a control circuit and the high side switch being controlled. The PCB substrate has first and second opposing surfaces 404 & (Fig.4, 402) with a side wall there between, and a first section of the magnetic core material (Fig.4, 124) extends inwardly into the PCB substrate from the side wall such that at least part of the magnetic core is located in the substrate between the first and second surfaces. Input contacts are provided on the first surface of the substrate for receiving an input drive signal, and the driver circuitry transfers the input drive signal through the primary and secondary side windings to the gate contact. Other arrangements include a switching circuit comprising the semiconductor switch and high side driver, and a module comprising a plurality of switching circuits on the same PCB substrate which may be used together with a switched capacitor arrangement to provide a multi-level switching module (Figure 12).

Title: Vehicle Routing
Inventor: DAVID MORGAN BROWN
IPC: G01C21/34
Filed: 2018-04-16
Abstract: A user specifies start and destination locations in a road network. Data associated with a road network, and with a network of vehicle charging locations, is retrieved from databases and is used together with a battery status parameter to determine a route between the start and destination locations and display the route on a GUI. This route may pass through one or more battery charging locations. An aggregated cost, which may represent the distance travelled, time taken, elevation change or an energy saving parameter, may be calculated for each route by totalling its segments. The battery status parameter may be its temperature. The viability of route segments may be assessed by determining if the current charge level at a node, or the full charge level if at a charging location, would be sufficient to arrive at the next node in the route. Unviable segments may be pruned from the network.

Abstract: An electrical switch 10 comprises first and second electrically conductive arms 11,21. The first arm comprises a conductive arcing portion 12 and a conductive main portion 13. The second arm comprises a conductive wheel 23 electrically connected to a conductive body 22 by a wheel axle 24 which extends along a wheel axis, the wheel being free to rotate about the wheel axis. One of the arms is displaced relative to the other to move the switch between an open configuration and a closed configuration in which the arcing portion contacts the wheel and the main portion contacts the body, wherein the arcing portion contacts the wheel before the main portion contacts the body. The arcing portion may comprise a pair of spaced apart arcing fingers 14 which receive the wheel and a pair of spaced apart main fingers 17 which receive the body. The fingers may be pivoted into the closed position by a pivot mechanism 32. Alternatively, the arcing portion may comprise a resiliently deformable rail 33 (figure 7) and one of the arms may be displaced linearly into the closed configuration. The switch is more resilient in high-current applications e.g. a train because the effects of the Lorentz force are reduced.

Title: Determination of spatial audio parameter encoding and associated decoding
Inventor: ADRIANA VASILACHE
IPC: G10L19/032
Filed: 2019-09-13
Abstract: Spatial audio parameters (eg. direction and non-directional energy ratios in different frequency bands from a mic array) are determined and encoded as metadata parameters for a block (M) of time-frequencies based on a first quantization resolution (eg. N=20 sub-bands). These metadata parameters are then output if the number of bits used to encode them (bits_dir0, fig. 4A, eg. 9 bits for azimuth, 7 bits for elevation and 8 bits for energy ratio for each sub-band in a block) is less than a predetermined number. If greater than this number, a second quantization resolution (eg. N=5 sub-bands) is used to encode the metadata parameters using a different number of bits (bits_dir1, fig. 4B), which is output if the difference between them is less than a threshold. If greater than a threshold, a third quantisation resolution is used to encode the parameters. The indices may be fixed-rate or entropy encoded based on which encoding uses fewer bits.
