Publication number: 20210219907Abstract: Dimensions of a surface feature are determined by capturing an image of the surface feature and determining a scale associated with the image. Structured light may be projected onto the surface, such that the position of structured light in the captured image allows determination of scale. A non-planar surface may be unwrapped. The surface may alternatively be projected into a plane to correct for the scene being tilted with respect to the camera axis. A border of the surface feature may be input manually by a user. An apparatus and system for implementing the method are also disclosed.Type: ApplicationFiled: November 9, 2020Publication date: July 22, 2021Inventors: William Richard Fright, Mark Arthur Nixon, Bruce Clinton McCallum, James Telford George Preddey

Patent number: 6118111Abstract: An inductive fluid heater is constructed from two concentric tubular members forming a fluid chamber therebetween. Fluid is supplied into the chamber by way of a manifold at each end of the concentric tubular members. A heating device is located within the chamber where the heating device is in the form of a shorted secondary coil of a transformer. The shorted secondary coil is in the form of a conductive tube. The transformer further includes a primary coil, a central core and a plurality of side cores to form a continuous constrained flux path. The central core surrounded by the primary coil is inserted into the inner concentric tubular member of the fluid heater. The primary coil may be powered by an AC high frequency supplier. Potential applications include fluid heating in general, particularly medical applications where blood, plasma and the like are required to be heated at high flows rates and under highly controlled conditions.Type: GrantFiled: November 5, 1998Date of Patent: September 12, 2000Assignee: BBMR LimitedInventors: Nigel Brent Price, William Richard Fright, Mark Arthur Nixon, Bruce Clinton McCallum
