Title: Mass spectrometric method and MALDI-TOF mass spectrometer
Inventor: Tobias Boskamp
IPC: H01J49/00
Filed: 2018-09-18
Abstract: A method of normalising the spectral intensities of mass spectrometry data comprises (i) forming an intensity profile for each individual spectrum, wherein the intensity profile describes the statistical distribution of intensity values within different mass ranges; (ii) forming an average reference profile for an ensemble of spectra; and (iii) transforming the individual spectra such that their intensity profiles correspond to the reference profile. The intensity profile may be formed by dividing the mass axis into sub-intervals, calculating quantile values for each sub-interval, and transforming the quantile values by computing the logarithms and calculating the differences between successive values. A reference profile may be calculated by determining the arithmetic mean of the individual intensity profiles. An individual spectrum may then be normalised to the reference profile by transforming the reference profile back into quantile values, considering the quantile values of the individual spectrum and of the reference profile as reference points of a transfer function, and applying the transfer function to intensity values of the individual spectrum.

Title: Positioning device, communications system and method
Inventor: DAVID SHARP
IPC: H04W64/00
Filed: 2018-12-20
Abstract: A communications system comprises first and second base stations BS1, BS2, wherein the first station can transmit a first signal 301 to the second station. The second station receives the first signal and transmits a second signal 302 back to the first station in response. The first station receives this signal and transmits a third signal 303 back to the second signal in further response. Meanwhile, a device operating within the system uses a receiving unit (401, figure 4) to receive each of the first, second and third signals and uses a delay time measuring unit (402) to measure the time between the device receiving the first signal and the second signal. The device also measures a first round trip time, this being the time between receiving the second and third signals and also measures a second round trip time and second delay time from at least one received signal. A calculating unit (405) calculates a first time difference of arrival based on the first and second round trip times and the first and second delay times. The time difference may be used to calculate a position of the device with respect to the stations.

IPC: H02P29/028
Filed: 2019-07-17
Abstract: A fault-tolerant electrical drive system comprises a rotary electric machine 101 comprising pn phases having a common connection point X, where p is a prime number and n is an integer greater than or equal to 1. A drive circuit module 102 has pn phase drive circuits 103a-c, 103u-w and a reserve drive circuit 103x; and a contactor module 104. The contactor module comprises: pn phase contactors 105a-c, 105u-w each of which is operable to connect one of the pn phases of the rotary electric machine to a respective one of the pn phase drive circuits; and a phase fault contactor 106x operable to connect the reserve drive circuit to the common connection point. Following a fault, the reserve drive circuit can be driven to simulate the normal behaviour of the disconnected faulted phase so that the electric drive system can continue operation. In an alternative arrangement, the phase fault contactor is operable to connect the reserve drive circuit to one of the phase windings. The fault-tolerant electric drive system may thereby be also capable of continuing operation if one of the phase drive circuits fails by switching to the reserve drive circuit, allowing operation to continue at full capacity.

Title: Method and apparatus for estimating closed-circuit hysteresis curves for magnetic materials
Inventor: JAMES PAUL DOUGLAS CLEWETT
IPC: G01R33/14
Filed: 2019-08-22
Abstract: A method for calculating the closed circuit hysteresis curve of e.g. a permanent magnet sample combines a mathematical model of the sample with open circuit measurements e.g. from a Pulsed Field Magnetometer (PFM). The model is used to create a hysteresis curve defined by variables which can be adjusted to best fit the measurements. From the best fit variables, the model can be adjusted to simulate the closed circuit hysteresis curve. The model may be a lattice of nodes. The minimum energy configuration of dipoles within the sample may be modelled. Periodic boundary conditions may be applied to model the closed-circuit environment. The local field of the model may be the sum of the external field and the self-demagnetisation field of the dipoles. Hamiltonian or Monte Carlo methods may be used to optimize the model. The invention may particularly be used for testing of rare earth magnets.

IPC: G06F13/16
Filed: 2019-10-29
Abstract: An apparatus 100 comprising interface circuitry 105 to receive memory access commands directed to a memory device, each memory access command specifying a memory address to be accessed. Scheduler circuitry 110 stores a representation of a plurality of states accessible to the memory device 115 and, based on the representation, determine an order for the received memory access commands. Dispatch circuitry 120 receives memory access commands from the scheduler circuitry and issues the received memory access commands, in the determined order, to be performed by the memory device. The representation can comprise potential transactions between states, which can be represented as a directed graph (figures 3, 4, 8, 9) or as a state machine representation. The scheduler can take into account the timing of any potential transactions or access commands so as to reduce latency and faults and can reorder so as to optimize according to timings, or according to power consumption. The scheduler may order subsets of the access commands which are received sequentially by the dispatch circuitry.

Abstract: In a computer comprising multiple processing units, a method of exchanging read only elements between the processing units is described. The read only elements may be code or data, such as vector or matrix data for an AI graph. A master processing unit is identified. At compile time, at least one shareable read only element is allocated to the master processing unit.
