  • Publication number: 20190323993
    Abstract: A defect detection method and apparatus detecting a defect in an object. The method comprises: obtaining ultrasound scan data derived from an ultrasound scan of the object under consideration, the ultrasound scan data being in the form of a set of echo amplitude values representing the amplitude of echoes received from the object during ultrasound scanning at certain spatial and temporal points; processing the ultrasound scan data to remove echo amplitude values received after a predetermined threshold time; generating at least one image from the processed ultrasound scan data; subjecting each generated image to an automated defect recognition process to determine whether there is a defect in the portion of the object represented by the image; issuing a notification indicating whether or not a defect has been found; and, if a defect has been found, storing the result of the automated defect recognition process in a defect database.

  • Publication number: 20190188855
    Abstract: An image processing method to sample the image to generate patches. Feature vectors are extracted from the patches, and the extracted feature vectors are partitioned into clusters, where feature vectors in the same cluster share a common characteristic. A portion of interest in the image is segmented. An aggregate bounding region creation process is carried out by finding the largest segment and creating a bounding box around it; determining which cluster contains the most patches within the bounding box of the segment; and adding the patches of the determined cluster to an aggregate bounding region for the portion of interest. The aggregate bounding region creation process is repeated for each other segment in order of size. The resulting aggregate bounding region contains all the patches associated with the portion of interest. The patches which fall outside the resulting aggregate bounding region are then removed from the image.

  • Patent number: 10210656
    Abstract: A method and apparatus for searching a database of 3D items using descriptors created for each item and for the 3D computer-generated model or the 3D physical object. The descriptor comprises a vector string comprising each of the feature vectors extracted from the images, and dimension-related features each representing a dimensional feature. The descriptor is created by obtaining 2D rendered images of the model by rotating the model about each different axis independently, and extracting a feature vector representing features. The model is rotated about the axes in angular steps which may be the same for each axis. The axes may comprise three mutually-perpendicular axes, where each angular step is in the range from 30° to 45°.

  • Publication number: 20160321380
    Abstract: A method and system of thermal computational fluid dynamics (CFD) analysis on a structure. A thermal CFD model of the structure is created using 3D-CAD software in which a volume of the structure, encompassing a third part, a portion of a first part which is adjacent to and includes a boundary between the first and third parts, and a portion of the second part which is adjacent to and includes a boundary between the second and third parts, is replaced by a notional fourth part. Thermal-CFD analysis of the thermal CFD model is performed using thermal conductivity of a fourth part that is calculated, based on known thickness of the fourth part, known thickness, the derived shape and known value of the thermal conductivity of the third part, and known values of the thermal conductivity of portions of the first and second parts.

  • Patent number: 9078121
    Abstract: A process for the automatic creation of ad-hoc networks between mobile devices in emergency and evacuation events. During an emergency or an evacuation event a command centre (20) issues a special emergency warning to mobile network operators, in response to which the operators broadcast over the mobile network (10) a trigger message to the mobile devices (11-14) that they service. Receipt of the trigger message causes the mobile devices (11-14) in a given geographical area to search for their neighbours and to form groups each having a leader, subsequent communication between the group and the mobile network (10) being conducted via the leader, communications within the group being conducted for example by using Bluetooth or WiFi. In this way, both resources in the mobile network and battery power of the mobile devices are conserved.
