Title: Performance verification of an image sensor mounted to a vehicle
Inventor: NIJUMUDHEEN MUHASSIN
IPC: G06T7/80
Filed: 2022-03-24
Abstract: A method for assessing the performance of an image sensor 706 mounted to a vehicle 702 comprises: aligning a collimator 716 with the image sensor, receiving sensor data from the image sensor based on aligning the collimator with the sensor, determining that the sensor does not satisfy the performance specification associated with the image sensor, and generating and routing an alert associated with the sensor based on this determination. The assessment of sensor performance may comprise the use of modulation transfer functions, mitre edge detection, ray angles, and/or reprojection errors. The method may comprise using a plurality of collimators which may be mounted to a frame 708. The frame may be positioned by a robot 712 to facilitate alignment of the collimators with the sensor.

Title: System and method for organising big-data and workstream parameters for digital transformations
Inventor: LAURENCE COLLINS
IPC: G06Q10/10
Filed: 2022-04-29
Abstract: A computer-based method comprises a cloud based hosting and analytical artificial intelligence (AI) platform and connecting users and users operating programs, including internal and external knowledge systems, programme applications and collaboration devices via secure means to the platform. Users and workstreams are authenticated, structured and unstructured data from the programmes are parsed, and sequence, volume, and intensity of challenges of challenges, problems and tasks are extracted to determine optimum solutioning profiles. Analytics are performed to prompt, promote, and prescribe solutioning and risk mitigating actions and determining risk profile, and challenges to be solved are clustered and sequenced relative to defined risk profile solution themes, previously successful solution attempts from across the crowd or community, and severity of risk relative to impact of a failed solution on transformation value objectives. Metric and graphical representations of the solutioning and problem-solving landscape are compiled and presented to mitigate risk, and the best approaches to restructuring programme workstream, team structures, task prioritisation and benefit realisation tracking are determined. In another embodiment, gaps are predicted, and emerging risks are flagged continuously during the lifecycle of programs, and the restructured workstreams are presented to the user.

Title: Environment detection system
Inventor: CHRISTOPHER DAHLIN RODIN
IPC: G06V20/56
Filed: 2022-05-13
Abstract: A method comprises capturing a first unpolarised image of a first field of view (FoV) 111 of the environment; capturing a second image of a second FoV 121 of the environment, the second image having a polarised portion at a first polarisation angle; capturing a third image of a third FoV 131 of the environment, the third image having a polarised portion at a second polarisation angle. The first, second, and third fields of view are at least partially overlapping in an overlapping field of view; the polarised portions of the second and third images overlap in the overlapping FoV 150. The polarisation state of the light from the overlapping FoV is calculated using the first image, the polarised portion of the second image and third images. Features of the environment are detected at least partially from the calculated polarisation state of incoming light in the overlapping field of view. Claims for a system and a method of retrofitting are also included. The invention aims to improve the detection of the environmental features (e.g. snow) of, or around, a road, and thus increase the situational awareness of a vehicle or vehicle operator.

Title: Improving fatigue resistance of steel catenary risers
Inventor: DANIEL KARUNAKARAN
IPC: E21B17/01
Filed: 2022-06-22
Abstract: A method of installing a steel catenary riser 14 comprises progressively unspooling and launching the riser from a reel-lay vessel 10. The riser is plastically deformed in a straightening process aboard the vessel downstream of unspooling and upstream of launching the riser. The straightening process is adjusted to form a series of two or more residual curvature loops 28 of locally increased curvature in a length of the riser suspended in the water column above a touch-down point. Successive curved regions of the series are separated and joined by a straighter portion 30 of the riser of lesser curvature than those loops. Buoyancy elements (Fig 5, 45) may be attached to at least one straighter portion of the riser above at least one of the loops of the series, or between successive loops of the series, or above the series of loops.

Abstract: 0 The present invention provides for a process for debossing and perforating a substantially continuous web of substantially planar thermoplastic film, using a forming structure having a patterned forming surface with holes and an opposed surface. The forming structure is open from the holes in the forming surface to the opposed surface. The web of film has an indefinite length, a first surface, a second surface, and a thickness which is the distance between the first surface and the second surface. The process comprises the following steps:(a) The web of thermoplastic film is provided with its first surtace proximate the forming surface of the forming structure. The forming structure moves in a direction of the length of the web of film and carries the web of film in that direction. The web of film is substantially entirely molten.(b) A fluid differential pressure is substantially continuously applied across the thickness of the web of film from a first position along the direction of movement of the forming structure to a second position. The first and second positions are fixed relative to the moving forming structure. The fluid differential pressure is sufficiently great to cause the first surface of the web of film to be urged against the forming surface and to cause perforations to be created in the web of film. Thus a web of debossed and perforated film is formed in the image of the forming surface from the web of film. The web of debossed and perforated film has a first surface and a second surface which correspond to the first surface and the second surface, respectively, of the web of film. Fluid differential pressure holds the web of debossed and perforated film against the forming surface.(c) The second surface of the web of film is contacted with a fluid having low heat transfer capacity for a period of time from when the web of film passes the first position through when the web of film is debossed and perforated. Thus, the web of film remains substantially entirely molten throughout this period of time.(d) Cooling fluid is applied to the second surface of the web of debossed and perforated film after the film is debossed and perforated and before the web of debossed and perforated film passes the second position. Thus the web of debossed and perforated film is cooled and is set by the time the web of debossed and perforated film passes the second position.
