Title: Method of decomposing a load of interest associated with bearing-supported equipment
Inventor: GEORGO ZORZ ANGELIS
IPC: G01M13/045
Filed: 2019-03-27
Abstract: Bearing 9 has rolling elements 8 at even spacing λ, and n sensing elements Sn at even spacing θ connected with stationary race 6. In operation, the rolling elements induce strains in the stationary race. Sensor signals sn exhibit phase difference Φ, dependent on λ and θ. A payload on the bearing causes a payload signature in sn at a ball-pass frequency. A disturbance (e.g. distorted element or race) causes a disturbance load signature at another frequency. The sn are digitised. A signature matrix M is constructed, describing how unknown strain basis functions associated with the payload and disturbance load influence sn; n is selected and θ optimised such that the rows of M exhibit orthogonality. M is used to linearly transform the sn, from which the strain basis function of the load of interest (payload or disturbance load) is estimated and used to decompose and determine the load of interest.

Title: System and method for identifying light emitter flicker
Inventor: JOSHUA CLOSE
IPC: H04N5/235
Filed: 2019-09-03
Abstract: Environment data 160 is received 210 that is indicative of objects in an environment, where one or more objects are identified as illumination objects 220 associated with a strobed lighting system. The environment data may be map data 172 which may be gathered from on-board car sensors, such as a camera, a lidar sensor, a radar sensor or a park distance control system sensor. In addition, image data 140 of at least a portion of the environment is received 230 from one or more imaging devices 110. Strobe lighting regions 240 of the image data which correspond to the illumination objects are determined by mapping the environment data to the image data. The strobe lighting regions are regions of interest 250 which may be subject to a flicker correction algorithm to correct the image data. The strobed light emitter objects may be, for example, street signs, street lamps, traffic lights, gantry signs or car headlights. An alleged advantage of the invention is that flicker mitigation algorithms may be directed to relevant regions of interest only thereby reducing power consumption.

Title: Drive circuit for a brushless motor
Inventor: STEPHEN GREETHAM
IPC: H02P27/16
Filed: 2020-12-03
Abstract: Brushless motor drive circuit, comprising: a bridge converter of bidirectional switches SW1-4 connected to the motor’s phase winding 21; and a controller 38 that configures the switches states (Figs. 4-8,11). Bidirectional switches have four states (Fig.3): ON, bidirectionally conductive; D1, conductive in a first direction; D2, conductive in a second direction; and OFF, non-conductive. A first configuration configures a first pair of bidirectional switches as ON, one switch of the second pair as OFF and one switch of the second pair in a diode state (Fig.4b). A second configuration switches one of the first pair of bidirectional switches OFF in order to allow current to freewheel (Fig.4c). A first configuration, which precede the second, may configure a first pair of bidirectional switches as ON and the second pair as OFF (Fig.4a). A fourth configuration, which suceeds the third, may configure the switch in the diode state to ON (Fig.4d) thereby reducing conduction loses during freewheeling. The controller may receive a signal indicative of a voltage polarity and chooses a diode state D1, D2 dependent thereon. The arrangement removes the need for a rectifier and prevents reversal of current due to back EMF.

Title: High-entropy alloy containing boron and rare earth and magnetic field treatment method therefor
Inventor: GUIRONG LI
IPC: C22F1/10
Filed: 2021-02-24
Abstract: A high-entropy alloy containing boron and rare earth and a magnetic field treatment method therefor. The whole treatment process is divided into two parts, i.e. pulse magnetic field heat treatment and low-temperature static magnetic field treatment. The pulse magnetic field heat treatment has high treatment energy and high treatment efficiency, and can effectively improve the conversion rate of a hard particle phase. The low-temperature static magnetic field further precipitates a particle phase on the basis of inhibiting the growth of grains, significantly refines the grains at the same time, and can effectively relieve internal stress, so that mechanical properties and anti-abrasion properties of the material are greatly improved, and the material has a wide range of applications.
