Title: Electrical power steering system
Inventor: JAMES OWEN PATRICK FARRELLY
IPC: B62D5/04
Filed: 2019-04-23
Abstract: An electric power steering system has a steering mechanism connecting a steering wheel to the road wheels of the vehicle, typically via a steering column 5. An electric motor 1 is connected to the steering mechanism. The system has column torque and column position sensors 6, 10 which generate signals corresponding respectively to the carried column torque and the angular position of the steering wheel or a steering column, and a processor 7 which receives the torque signal and column angle signals and generates a torque demand signal. Processor 7 uses a boost curve to determine an assistance torque based on the column torque signal, and determines a friction compensating torque signal based on observations of the column torque and column angle signals over time and on an estimate of static friction in the steering mechanism. A torque demand signal is produced as a function of the friction compensating torque and assistance torque signals. The friction compensating torque signal assists a driver in overcoming static and/or kinetic friction in the steering mechanism.

Title: Precursor selection for data-dependent tandem mass spectrometry
Inventor: JENS DECKER
IPC: H01J49/00
Filed: 2019-05-15
Abstract: The invention relates to selecting precursor or parent ions from an ion mobility-mass map for fragmentation based on clustering these peaks in the mobility-mass space. In a first measurement cycle, a first set of ions are separated according to ion mobility and mass, e.g. without filtering and fragmentation. A peak list is produced, and weights or scores are assigned to the peaks such that a higher weight is assigned to a peak when other peaks (especially those of high intensity) are near or proximate to the peak. For example, the weight may be the sum of the distances measured to other peaks of the peak list further weighted by the intensity of those peaks. Peaks with weights above a threshold or having the highest weighted intensities within a neighbourhood are selected as precursor ions for a second measurement cycle, in which a second set of ions are mobility separated and mass filtered corresponding to the selected precursor peaks and fragmented to acquire fragment mass spectra. The method may further comprise determining peaks corresponding to isotopic patterns of a substance and selecting only the mono-isotopic mass of the substance.

Title: Organic light emitting display device and driving method thereof
Inventor: HYUNWOOK KIM
IPC: H01L27/32
Filed: 2019-06-12
Abstract: The organic light emitting display device according to the present disclosure comprises an input unit configured to receive image data input at a variable frame frequency, a sensing control unit configured to generate a sensing control signal, RT#, for sensing pixels to which the image data is to be applied, and a thin film transistor (TFT) compensating unit configured to sense driving characteristics of a driving element included in the pixels according to the sensing control signal to output a first sensing result. In each frame the vertical active period, VAP, during which image data is applied to the pixels, is fixed and the vertical blank period, VBP, during which no image data is applied to the pixels, is varied in order to achieve the variable frame frequency. The sensing control signal is applied to the pixel in a vertical blank period. By extending the vertical blank period in which the pixel sensing takes place the time required for the updated compensation can be reduced as more sensing actions can be carried per frame.

Title: Systems and methods to determine rotational oscillation of a drill string
Inventor: BENJAMIN PETER JEFFRYES
IPC: E21B47/007
Filed: 2019-11-15
Abstract: Embodiments of the present disclosure relate to a tangible, non-transitory, computer-readable medium that stores instructions executable by one or more processors, in which the instructions cause the one or more processors to determine a threshold value associated with an axial acceleration oscillation amplitude at a drill bit, in which the drill bit is a part of a drilling system. The instructions further cause the one or more processors to receive an operating parameter value of the drilling system, compare the operating parameter value with the threshold value, and adjust an operation of the drilling system, e.g. drilling fluid flow, rotation rate and feed rate, in response to comparing the operating parameter value with the threshold value. The threshold may be determined via simulation or historical data. The axial oscillation is used a s proxy for high frequency, >50Hz, rotational oscillation at the drill bit.

Title: Enhancing privacy by obscuring traversal using relays around network address translator (TURN) connections, and related methods, systems and computer-readab
Inventor: ALAN B JOHNSTON
IPC: H04L29/12
Filed: 2015-01-27
Abstract: A method and system to obscure Traversal Using Relays around Network Address Translators (TURN) connections. A TURN server receives a request for provision of a first TURN service from a TURN client to a TURN peer. The presence of the TURN server is masked by the TURN server from the TURN peer and communications between the TURN client and the TURN peer are relayed based upon the masking. The masking may comprise: (i) allocating a TURN signalling address that is different from an allocated TURN relayed transport address (RTA), (ii) silent discard of inauthentic ChannelData messages from the TURN peer by the TURN server, (iii) allocating a TURN RTA that is unaffiliated to an enterprise server farm. Relaying communications between the TURN client and the TURN peer based on the masking may comprise using a first RTA for the first TURN service and then selecting a second RTA for a second TURN service. The second RTA may be the same as the first if the same TURN client has made the second TURN service request. The advantage of the invention is that it prevents the TURN peer from detecting that the TURN client and TURN server are being concealed.
