Title: Determination of material
Inventor: SERGE MAITREJEAN
IPC: G01V5/00
Filed: 2018-10-05
Abstract: A method determines a material in a cargo comprising a first object made of a first material and a second object made of a second material. The method comprises obtaining S1 an inspection image of the cargo for at least two levels of radiation energy. Equivalence data is obtained S2 associated with mass equivalence of at least one of the first material and the second material with respect to a reference material, for the at least two levels of radiation energy. Observation data is obtained S3 based on the image data and the equivalence data, and at least one of the first material and the second material is determined S4 based on the obtained observation data. The mass equivalence may be the thickness of an object made of reference material (e.g. iron, steel, lead, aluminium, poly methyl methacrylate) associated with the same radiation transmission as a radiation transmission associated with a thickness of an object made of the given material. The equivalence data may be obtained in a calibration step.

Title: Device identification with quantum tunnelling currents
Inventor: PATRICK CAMILLERI
IPC: H04L9/32
Filed: 2019-04-17
Abstract: A method is disclosed for determining an identifier value for a device having an array 300 of individually addressable cells 310, each cell having one or more electronic components 200 (e.g. transistors or capacitors) comprising a potential barrier that can be crossed by charge carriers due to quantum tunnelling. A number of cells are selected and for each cell in the selection a potential difference is applied across the electronic component such that charge carriers may tunnel through the barrier. The resulting quantum tunnelling current is compared to a reference electrical signal, and from the comparison, an identifier value (e.g. a bit value) is determined for the cell. The cell identifier values are used to determine an identifier value for the device. The advantage of a physically unclonable function (PUF) which uses leakage current from transistors or capacitors, is that its output is largely invariant to environmental factors, e.g. temperature.
Patent GB-2587235-A (GB)
Title: Apparatus and method for network scheduling
Inventor: MARCO RUFFINI
IPC: H04Q11/00
Filed: 2019-09-20
Abstract: A scheduler for scheduling network traffic in a passive optical network (PON) which receives high and low priority traffic in a multi-tenancy environment. The scheduler has first and second traffic policers which each separate network traffic into green and yellow categories for the high and low priority traffic depending on whether the information rate is less or more than a committed or average information rate (CIR) at which data packets are admitted to an optical network unit (ONU). Rate limiters limit the rate of flow of the yellow labelled network traffic to bring it into compliance with a desired traffic profile and scheduling modules combine the green and yellow labelled high and low priority traffic as outputs to the PON. The purported advantages include improving latency and efficiency in downstream transmissions from an Optical Network Unit (ONU) to the PON.

Title: Spatial audio representation and rendering
Inventor: JUHA TAPIO VILKAMO
IPC: H04S7/00
Filed: 2019-10-11
Abstract: A spatial audio rendering system receives a spatial audio transport signal 122 with associated metadata 124, and obtains both a loaded data set 126 (eg. 5.1 format, direct room impulse or Head Related Transfer Function HRTF) and a predefined data set 300 or 392 (of eg. reverberative room impulse or HRTFs with poor directional resolution) related to binaural rendering in order to generate a binaural audio signal based on all three. The sets may be divided 301 such that it may be determined that the late, reverberative second part has an error, whereas the first, early, directional portion is error-, noise- or corruption-free, and the dividing process may comprise a roll-off window function.
Patent GB-2589558-A (GB)
Title: Separator
Inventor: KETIL PETTERSEN
IPC: E02B15/04
Filed: 2019-10-23
Abstract: A separator, for separating oil and water, has an angled separator bed 18, which may be between liquid inlet 12 and liquid outlets (outlet 16 for water, and outlet 14 for oil). The tilted separator bed 18 may be angled downwards, with gravity causing the liquid to flow. Liquid on the inclined separator bed 18 may be kept shallow, to encourage hydrocarbon gases to escape. The separator may operate at ambient pressure, with the angled separator bed 18 being open to the atmosphere. An adjustable weir plate may allow oil to pass to outlet 14, while preventing water to escape. Baffles (figure 3) may restrict fluid flow, e.g allowing oil to flow over the top, and water to pass underneath, while holding back the dispersion near the interface. The separator may be used offshore, e.g. on a floating vessel.

Filed: 2020-06-04
Abstract: Head mounted display (HMD) comprising: gaze detector (1210, Fig.12); circuitry to receive an input indicating an eye condition associated with partial vision loss (1220, Fig.12); and a processor to generate display images in dependence upon the eye condition and gaze direction (1240, Fig.12). Calibration images may be displayed to determine a point of attention 1720 and a position of a target object 1740 thereby calculating one or more vision offset parameters such as offset distance and offset angle. Offsets may be determined in two-dimensions. Offset parameters may be calculated using time and number of saccades used to locate the target object in the calibration image. The processor may generate images where a viewpoint of a virtual camera or the position of an object in the image have been adjusted by the offset. A portion of the generated image around the offset object 1740 may have a higher resolution than the rest of the image. The detected gaze direction may intersect a fovea portion of the retina and a calculated modified gaze direction intersect a different portion of the retina. The gaze of both eyes may be tracked. The eye condition may be macular degeneration, glaucoma or cataracts.

Title: A Method and Apparatus for Cooling One or More Power Devices
Inventor: SIMON DAVID HART
IPC: H02P29/68
Filed: 2020-12-23
Abstract: A method of cooling a plurality of power devices used to generate a three-phase output AC voltage. Based on power device stress data, one or more power switches is identified as requiring more cooling than other of the switches. All of the switches are controlled using Pulse Width Modulation (PWM) to apply a common mode component voltage to each of the three phases for at least a portion of one or more output AC voltage segments. The common mode component voltage has a maximum amplitude that is sufficient to clamp the phase AC output voltage of the identified phases to the positive supply rail voltage and/or negative rail supply voltage when the respective phase AC voltage is approaching respectively the positive supply rail voltage or negative supply rail voltage in order to cool the identified switch. The method may be used in an inverter for powering a multi-phase electrical load such as a motor or generator.
