Abstract: A vehicle sub-system 1 (e.g. for an electric or hybrid vehicle, EV, HEV, BEV, NEV, PHEV) includes an electrical power bus 12, 14, 16 for distributing electrical power from an electrical energy storage means 10 (e.g. battery) to electrical components of the vehicle (e.g. an electric traction motor/generator 20). The sub-system also includes a means for disconnecting the energy storage means from the bus; a means for measuring the potential difference between a rail of the bus and a chassis 18 of the vehicle; and a means for connecting and disconnecting the rail of the bus to the vehicle chassis. The rail of the bus is connected to the chassis if the measured potential difference between the rail and the chassis exceeds a predetermined value, until the potential difference between the rail and the chassis is less than the predetermined level. The rail is then disconnected from the chassis. The means for connecting and disconnecting the rail to the chassis includes the means for measuring the potential difference between the rail and chassis and may consist of a first resistance and a first switch, as part of an isolation monitoring system 6 (IMS). This technique may be used to at least partially discharge a Y capacitance on any, or all, rails of the bus in the event of a vehicle collision.

Title: Optimized water quality injection strategy for reservoir pressure support
Inventor: ARILD SAMUELSBERG
IPC: E21B43/40
Filed: 2018-10-18
Abstract: A method for supporting the pressure of a subsea hydrocarbon reservoir comprising: recovering produced fluid from the reservoir; separating produced water from the produced fluid; providing seawater; mixing the produced water and the seawater at a determined ratio in order to provide mixed water having a desired temperature; and injecting the mixed water into the subsea hydrocarbon reservoir. Provides a wide range of target temperatures between that of seawater and the produced water. A system for supporting reservoir pressure comprises production 2 wellheads and water 3a and gas injectors connected to an unmanned production platform 9 having processing equipment and a seawater treatment unit 12. A controller controls mixing and reinjection which may account for factors such as the temperature of the reservoir and anticipated produced water flow rate. The ratio and flow rate of mixed waters may change during the process. Provides a way to dispose of produced water and minimise risk of thermal fracking especially in low, temperature, low overburden reservoirs given that produced water is typically heated during separation and processing where heat exchangers are not practicable.

Title: Handling exceptions in a machine learning processor
Inventor: Alan Graham Alexander
IPC: G06F11/36
Filed: 2019-01-11
Abstract: A processor (chip) or method to execute vertices (nodes) of e.g. a machine learning application. Each vertex is assigned to a programming thread having a vertex identifier (i.e. address of the executing thread; may be in a status register, 39, fig 2). Debug hardware 122 (fig 1) holds a vertex break identifier (BREAK ID) and the debugger compares the vertex identifier with the vertex break identifier to raise an exception event. In other words, the debugger is raising an instruction exception for a thread associated with a vertex when a break identifier stored in debug hardware matches the executing thread address. The BREAK ID may be placed in a vertex break register, VBRK, 1107. The vertex break can be set by an enable bit. The processor may be barrel-threaded with each tile having registers for multiple threads and a scheduler. A supervisor thread (subprogram) may coordinate the execution of worker threads operating in interleaved execution time slots. The chip may operate in a bulk synchronous parallel scheme and the supervisor thread may perform a synchronisation instruction by ensuring that some threads do not begin until other threads make certain data available (barrier synchronization).
