Title: Fuel injector control using noise signal
Inventor: NOUREDDINE GUERRASSI
IPC: F02M57/00
Filed: 2017-09-25
Abstract: A fuel injector 12 comprises a body 28, an electro-valve 42 and a needle valve member 34. The electro-valve moves to open / close a spill orifice to vary the pressure in a control chamber 45. The needle valve member moves due to control chamber pressure to open or to close spray holes. The body is hit, in use, by the electro-valve when reaching a closed position, when reaching a fully open position OPV, when reaching a closed position CPN and when reaching a fully open position OPN. The hits are recorded by a noise sensor (60, figure 5) fixed to the body generating a signal (S60, figures 10, 11) representative of the hits. The sensor may comprise a piezo-ceramic washer (62, figure 4) compressed between a base (64, figure 4) and a ground metal washer (66, figure 4). Fuel injection equipment, electronic command unit and closed loop method of control are also claimed. The method of control includes measurement of injection event timings, recording the rough signal of the noise sensor, integrating the signal to generate a cumulative signal, identifying slope variations in the cumulative signal, which are representative of knock, to adjust fuel quantity of subsequent injections.

Title: Methods and apparatus for determining the orientation of a tire mounted device
Inventor: WILLIAM DAVID STEWART
IPC: B60C23/00
Filed: 2018-04-30
Abstract: A method of determining an orientation of a tire mounted device with respect to a wheel rim. With the wheel in a designated orientation and not rotating, a polarity of acceleration along a vertical axis is determined using an acceleration sensor. The designated orientation may be face up or face down 603, e.g. in a factory assembly line, with the axis parallel to the wheel axle (y; figs 3, 5) aligned to the vertical. Alternatively, it may be with the wheel upright and at an angular position such that one acceleration sensor axis (e.g. x, z; fig. 5) is disposed vertically (re fig. 8). The polarity is then used to determine which of two absolute orientations the device is in, i.e. is the sensor axis up or down. The absolute orientation is correlated with the orientation of the wheel to determine which of two orientations with respect to the wheel rim the device is in. The device may be a tire pressure monitoring sensor and the polarity determination may be in response to detecting tire inflation or receiving a wireless instruction. The device may erase the data when it detects the wheel has been removed from the vehicle.

Title: System for configuring demand response for energy grid assets
Inventor: Brecht Dierckx
IPC: H02J3/14
Filed: 2019-10-25
Abstract: A method of controlling assets connected to an electricity distribution grid 300. The assets are configurable to adjust energy flow to/from the grid in response to changes in operating conditions of the grid. For each asset, a trained neural network model 304 takes an asset configuration as input, the asset configuration specifying a response of the asset to variations in local detected operating conditions, and outputs performance indicators relating to the operation of the asset when operated using the asset configuration. The outputs of the neural network models are provided as inputs to an optimization function. A search process alters the optimization function by varying asset configurations for the assets until a termination criterion is met. Preferably, the asset configurations are iteratively adjusted, altering the performance indicators output by the neural networks, thus optimising the optimisation metric. The final asset configurations are then used to control the assets to provide a coordinated demand response service.
