Title: Finned coaxial cooler
Inventor: CHARLES PENNY
IPC: F28F1/40
Filed: 2017-01-30
Abstract: A heat exchanger (100, Fig. 1) suitable for cooling hot gas using a liquid coolant comprises a plurality of parallel finned heat exchange tubes 2102 surrounded by a tubular outer body. Each finned heat exchange tube comprises an inner tube with a plurality of fins contacting an inner surface of the inner tube. A portion of gas flows through the inner tube and liquid coolant flows between outer surfaces of the inner heat exchange tubes and an inner surface of the tubular outer body, to exchange heat between the gas and liquid coolant. The fins may be formed from a cylindrical corrugated sheet of material which includes a gap (902, Fig. 9) between first and second ends (2410, 2420, Fig. 24) of the sheet. Raised protrusions (2411, Fig. 24) on the first end of the sheet may partially overlap the second end. The fins may have undulations or a nonlinear shape and may have radially extending slots (2301-2309, Fig. 23A). There may be three fin types (2001, 2002, 2003, Fig. 20) of different lengths. The heat exchanger is suitable for use in an internal combustion engine exhaust gas recirculation system.

Title: Image data encoding and decoding
Inventor: STEPHEN MARK KEATING
IPC: H04N19/91
Filed: 2019-06-27
Abstract: Image data encoding comprising a first data encoder configured to generate output data bits for input symbols at a variable number of output data bits per input symbol (e.g. CABAC encoding), and a second data encoder configured to generate output data bits for input symbols at a fixed number of output data bits per input symbol (e.g. bypass encoding), where a symbol to be encoded is encoded either by the first data encoder 2150 or the second data encoder 2140 based on a prediction of whether a constraint will be met, where the constraint defines an upper limit to the number of symbols that may be expressed by a block/unit of output data relative to the size of said block/unit of output data. The object is to reduce the need for zero padding the slice or picture with CABAC zero words in order to meet a throughput constraint. Preferably, the constraint is: the number of binarized symbols in the output data unit (BinCountsInNALunits) is less than a constant times the number of encoded bytes for the output data unit (NumBytesInVclNALunits) plus a value based on the size of the picture, tile or slice and the minimum size of coding units.

Title: Improvements in and relating to positioning reference in a telecommunication system
Inventor: Yinan Qi
IPC: H04W72/04
Filed: 2020-05-01
Abstract: In a telecommunication system, position reference signals (PRS) are selectively muted. The PRS configurations may be in the form of comb patterns such as comb-3 (fig. 1a), comb-6 (fig. 1b) or comb-12 (fig. 1c), and a muting periodicity may be selected on the basis of the selected pattern. The muting periodicity may also be defined on the basis of numerology and may be configured by a location server. For beam sweeping, one positioning occasion may consist of multiple PRS resource sets and muting may be applied within each resource set or across multiple resource sets i.e. muting may be intra-resource set or inter-resource set. A user equipment (UE) may report a resource set ID or a cell ID to the telecommunication system. In a second aspect, the PRS may be muted over only a part of the frequency band. The scheme may be used by base stations (gNBs) in a 5G New Radio communications network.

Title: Network path testing via independent test traffic
Inventor: MARTIN VICKERS
IPC: H04L43/50
Filed: 2021-09-10
Abstract: A method 700 for testing a network wherein a test data frame is dispatched by a network interface device a set number of times S730, specified by a stored send count value S710. Using the same test data frame repeatedly requires less protocol processing resources, allowing network protocol processing to be performed in parallel with the repeated dispatching of the test data frame to produce further traffic for dispatch over the network S740, and to dispatch traffic over the network S750 prior to the completion of the repeated dispatching of the test data. A method (900, Figure 9) for processing received test traffic is also disclosed. The network interface device checks a first received test data frame using error code contained within said frame, updates a receive count value in response to the frame passing this check and discards the first test frame. The test frames are not required to be further processed and provided to a driver of the network interface device. In this way, the processing and buffering capacity in the network interface device is available for handling further traffic in parallel with the test traffic.

Title: System and apparatus suitable for facilitating personalized user experience in a vehicle, and a configuration method in association thereto
Inventor: DIBAS KUMAR SARKAR
IPC: H04N13/337
Filed: 2022-01-26
Abstract: An apparatus for providing an occupant of a vehicle a private personalised viewing experience comprises a display module which may be paired with an auxiliary device (e.g. viewing glasses). The display module comprises a first polariser 302a to receive light from a light source and output light of a first polarisation state. This light is passed through a liquid crystal (LCD) layer 302b which may selectively rotate the polarisation orientation of light leaving the first polariser, dependent upon a voltage applied to the LCD layer. An auxiliary device receives light from the LCD layer to facilitate viewing of visual content by the vehicle occupant by means of a second polariser layer 302c in the auxiliary device which only passes light corresponding to the desired visual content. The auxiliary device may be provided in the form of a wearable device such as polarising glasses/spectacles. Other vehicle occupants viewing the LCD layer without the auxiliary device will merely perceive an illuminated screen with no perceptible image detail. The apparatus and associated method allow for private viewing of content which remains invisible to other viewers.
