Title: Optical inspection device.
Inventor: EPSTEIN RUTH
IPC: G01B11/02
Filed: 1993-08-03
Abstract: An inspection device such as endoscope 1 is provided with an additional light source for illuminating a viewed object with a collimated beam which provides a light pattern of known dimensions superimposed on the object. A recorded image of the object can be analysed to determine the absolute size of features of the object, by comparison with the dimensions of the light pattern. The pattern may be a disc or a grating and its distortion may be used to estimate the orientation of the illuminated surface. Fibre optics may guide the light to the object and back to a CCD camera. <IMAGE>

Title: Computed tomography
Inventor: BURCH STEPHEN FRANK
IPC: G01N23/04
Filed: 1994-01-27
Abstract: A computed tomography apparatus including a source (12) of radiation, a turntable (30) to support an object (16), and a fluorescent screen and a video camera, or an image intensifier (17, 18) and a camera (20), to detect the transmilled radiation, is modified by the incorporation of a linear drive means (28) to move the object (16) laterally into different positions at each different angular orientation. The lateral movements are such as to move the image on the input screen (17) a random number of pixels of the digitised video signal. The digitised signals are corrected to allow for the lateral displacement of the image, before being processed to calculate a tomographic image. Artefacts due to coherent noise, which would give ring patterns on the reconstructed tomographic images, are hence suppressed. <IMAGE>

Title: Method for scanning the surface of an object
Inventor: PRESTIDGE TIM
IPC: G01B21/20
Filed: 1994-03-30
Abstract: A workpiece surface 30 is digitised by scanning it with a probe stylus 8 Digitised coordinate data for points such as P1 - P6 on the workpiece surface are subjected to a filtering algorithm, to remove redundant data when the surface is relatively flat or planar. Top and bottom tolerance vectors TV0, BV0 are defined, starting from a first point P1 and lying at a given tolerance h above and below a second point P2. Next, a direct vector DV1 is defined between the point P1 and a third point P3. If the vector DV1 lies outside the tolerance band between the vectors TV0 and BV0, then point P2 is deemed to be required and is not filtered out. Otherwise, the data for point P2 is deemed to be redundant and is rejected. In this case, new tolerance vectors TV1 and BV1 are now defined, starting from point P1 and passing within a tolerance h above and below point P3. From the four vectors TV0, TV1, BV0, BV1, a pair of vectors TVn, BVn is selected for a further iteration of the process, based upon which of these vectors lies closest to the vector DV1. <IMAGE>

The seal inserts 36 are open to the bottom of the housing 24 and permit debris to be ejected from the valve assembly 20. Each spring may be formed to have ends which are not connected and each valve liner 26 may be positioned by inserting a locator tab on an exterior flange of the liner into a corresponding depression in the valve housing (Figs. 14 - 16, not shown). The springs 34 may be replaced by separate springs acting of reinforced zones of the valve liners 26 (Fig. 11, not shown). <IMAGE>
