Abstract: A method for determining the quality of a weld bead includes producing a weld bead along a work surface during a welding process and scanning the weld bead with a scanner to obtain positional data points for defining a weld bead profile. The weld bead has a weld toe zone or region, which is formed at the interface between the weld bead and the work surface.  A curve fit is determined for the weld bead profile based on the positional data points obtained by the scanner. The toe radius is derived based on the curve fit and is then compared to a first predetermined limit and a second predetermined limit, greater than the first predetermined limit, to determine the quality of the weld bead. If the weld toe radius is less than the first predetermined limit or greater than the second predetermined limit, the welding process is modified to produce a weld bead with a toe radius that falls within the desired range. In one embodiment the weld toe radius is determined from first and second derivations of a numerical relationship representative of the curve fit. In another embodiment the curve fit is compared to a plurality of curves to find a corresponding match and the weld toe radius is determined from the matching curve.

Title: Cardiac motion tracking using cine harmonic phase (harp) magnetic resonance imaging
Inventor: PRINCE JERRY L
IPC: A61B5/055
Filed: 2000-04-14
Abstract: The present invention relates to a method of measuring motion of an object such as a heart by magnetic resonance imaging. A pulse sequence is applied to spatially modulate a region of interest of the object and at least one first spectral peak is acquired from the Fourier domain of the spatially modulated object. The inverse Fourier transform information of the acquired first spectral-peaks is computed and a computed first harmonic phase image is determined from each spectral peak. The process is repeated to create a second harmonic phase image from each second spectral peak and the strain is determined from the first and second harmonic phase images. In a preferred embodiment, the method is employed to determine strain within the myocardium and to determine change in position of a point at two different times which may result in an increased distance or reduced distance. The method may be employed to determine the path of motion of a point through a sequence of tag images depicting movement of the heart. The method may be employed to determine circumferential strain and radial strain.

Filed: 2000-05-11
Abstract: A system, apparatus, and method for underwater tagging of marine fauna involves emplacement of a tagging unit that can be used for example in a fishing trawl and establishment of communications with the unit through a cable wire that may be conventional. Numerous types of data can be recorded in relation to the tagging, including the ID of the tagged animal, and two- and/or three-dimensional images of the animal, to be used at a later date wh en the tagged animal is recovered. The method decreases tagging mortality and t he biological effects of tagging on the animals, since they are not exposed to temperature and pressure changes, human handling and, at times, anesthesia. The embodiment makes it possible to tag deep-sea species that have never bee n tagged due to the fact that they would not survive the ambient changes of coming to the water's surface.

Title: Robust autofocus system for a microscope
Inventor: GEUSEBROEK JAN-MARK
IPC: G02B7/28
Filed: 2000-05-30
Abstract: The present invention provides a method and apparatus for autofocusing of an optical instrument, especially a micro-scope (10). The autofocus scheme includes a digital gradient filter for generating a focus score from each captured image. Images may be captured at various positions and the focus scores analysed to determine a focus score maximum. The position correspond-ing to this maximum is then taken as the focus position. The spatial extent of the filter is preferably settable so that the digital filter settably selects elements of the image depending on their size in the image.  Thus, the filtering process is controllable so that it is influenced by elements of the image whose size may be specified by the operator indirectly by way of the spatial extent of the filter.  This allows the exclusion of small or large elements of the image from the autofocusing procedure which the filter should preferably ignore. The autofocus scheme is particularly useful for autofocusing biological specimens.
