Patent GB-2570364-A (GB)
Title: Jarring apparatus
Inventor: PETER BARNES MOYES
IPC: E21B31/113
Filed: 2018-10-11
Abstract: Jarring apparatus comprises impact surfaces in the form of a hammer (fig 1B, 24) and an anvil (fig 1B, 30) rotatable relative to each other. The impact surfaces are biased together. A lifting structure is provided in the form of two coaxial cammed sleeves 34,36. Relative rotation of the cammed sleeves 34,36, fixed relative to one of the hammer or the anvil, operates to sequentially lift and drop the hammer to strike impact on the anvil. The hammer is released before lifting phase is completed to prevent drop-off portion 44 of the cam lobe 40 taking full strike of the hammer and anvil impact. Annular no-go lip 58 protruding from the lifting sleeve prevents the cam lobes contacting (fig 4D) prior to the lifting phase (fig 4A). Valve assembly (fig 1B, 96) acts to hydraulically lock the lifting sleeves 34, 36 and hammer. The valve assembly is closed during the start of the lifting phase so the hammer separates from the anvil. The valve opens prior to the dropping phase to release the hammer while lift may continue and protect the cams 42,52. The valve is a rotating sleeve exposing longitudinal channel allowing communication between hydraulic chambers (fig 1B, 74,80).

Title: Method and apparatus for display monitoring
Inventor: Mark Richard Austin
IPC: H04N17/04
Filed: 2020-01-28
Abstract: A method for monitoring display of content on a screen comprises: providing a screen 301 and sensor 303, positioning the sensor to collect light emitted from substantially the entire screen active area 302, and monitoring intensity of at least one colour of light received by the sensor, obtaining at least one measured colour value. A primary sensor calibration may be conducted to obtain a colour correction factor, by displaying a single known colour value (e.g. black) across substantially the entire (whole) screen active area, comparing the measured value to the known color value, and determining a difference between known and measured colours. Modification of the measured colour value with the colour correction value generates calibrated colour value(s). Monitoring colour intensity may comprise measuring red, green, blue and white (RGBW) light received by the sensor, and further converting RGBW light to a measured hue value; secondary calibration of the sensor obtains a hue correction factor. A single known hue may be displayed across substantially the entire screen active area, allowing comparison of measured and known hue values; an average hue correction may be calculated. Hue values may be recorded over a time period. The image sensing detector may comprise an optical fibre, not obscuring the screen in use.

Title: Time of flight mass spectrometer and method of mass spectrometry
Inventor: HAMISH STEWART
IPC: H01J49/40
Filed: 2020-03-02
Abstract: A time-of-flight mass spectrometer comprises a pulsed ion injector (e.g. an orthogonal accelerator) for forming an ion beam, a detector, and an ion focusing arrangement (e.g. drift focusing lens 12, figure 1) located between the ion injector and the detector for focusing the ion beam in at least one direction orthogonal to the ion path. The ion focusing arrangement is supplied with a variable voltage that is dependent on a charge state and/or an amount or abundance of ions of at least one species of ions in the ion beam. The charge state and/or an amount of ions may be acquired from a pre-scan, predicted, or measured on the fly. The lens preferably normalises the beam spatial dispersion of multiply charged ions to that of singly charged ions. The invention may overcome the problem of space charge effects that multiply charged ions and ion packets having a large number of ions can suffer as a result of greater charge density.
Patent GB-2585271-A (GB)
Title: Cyclic redundancy check computation circuit, communication unit, and method therefor
Inventor: Robert G Maunder
IPC: H04L1/00
Filed: 2019-07-01
Abstract: A cyclic redundancy check code is conceptually created by dividing a block of data by a generator polynomial (e.g. 1D6+1D5+0D4+0D3+0D2+0D1+1D0) and appending the remainder to the data as a checksum to create a codeword. The invention concerns verifying such a codeword to determine if an error has occurred. It divides the received codeword by the inverse of the generator polynomial (e.g. 1D6+0D5+0D4+0D3+0D2+1D1+1D0 , the coefficients are applied in reverse order) to create a syndrome (pk-K=18-23) and if the syndrome has a zero value that indicates no errors. In embodiments the codeword is placed in reverse bit order (sk+0-18) before the inverse generator polynomial is applied. In embodiments the syndrome may be derived using an inverse generator matrix embodied as a look up table. This may avoid the need for some zero filling when calculating the syndrome. The matrix may be used embodied in multiple memory addresses operated on by parallel processors.

Title: Method for manufacturing a memory resistor device
Inventor: LONGFEI ZHAO
IPC: H10N70/20
Filed: 2021-09-21
Abstract: A method of manufacturing a memory resistor (memristor) 100 includes depositing an electrically insulating dielectric layer (e.g. silicon oxide, SiOx) 110 over a first electrode 105, performing ion bombardment with an ion beam (e.g. argon noble gas ions) 210 to form a defect in the dielectric layer, and depositing a second electrode over the first electrode and dielectric layer. The defect may be structural, e.g. oxygen vacancies. The dielectric layer may be electroformed by applying a voltage between the first and second electrodes to form conductive filament pathways at the defects. A masking layer (e.g. molybdenum) with cavities may be used to control ion impact location and also act as a grounded charge dissipation layer to prevent charge accumulation, therefore producing more consistent and predictable distribution of defects and electrical properties e.g. resistive switching voltage. Control of ion beam energy may determine depth of defects from the dielectric surface.
