摘要： An apparatus determines the position of an object with respect to a reference coordinate system. Preferably, the apparatus includes a target attached to the object, the target moves within a defined region and has a surface with a first pattern thereon. A projection device projects a second pattern upon the surface. A sensing device provides an image signal indicative of the target surface including the first pattern and the second pattern. An analyzer receives the image signal and determines the position of the object based on the position of images of the first pattern and the second pattern.

摘要： An optical input apparatus (10) for use with a weld evaluation monitor (14) to determine the concentration of hydrogen in a weld arc atmosphere (62) including weld arc plasma and shield gas is disclosed as including an optical fiber bundle (16) having a single optical input (18) and a plurality of optical outputs (22). The optical fiber bundle is disposed to receive, at its optical input, electromagnetic radiation emitted from the weld arc atmosphere and, because the optical fiber bundle has an individual optical fiber path distribution that is completely randomized, to communicate proportional amount of the radiation to each of its optical outputs independent of the angular disposition of the fiber bundle. Radiation having only specific wavelengths of hydrogen, shield gas and background emissions are allowed to pass through respective optical line filters (56) to associated optical transducers (58), which generate electrical output signals having amplitudes representative of the intensities of the hydrogen, shield gas and background emissions. Also disclosed is a signal processing module (12) for receiving the electrical output signals and determining therefrom the hydrogen concentration in the weld arc atmosphere. A method for using the apparatus to determine the hydrogen concentration is also disclosed.

摘要： A non-contact, displacement transducer (optical extensometer), which is relatively simple to make and operate, and therefore low cost, utilizes 35 mm camera optics for the lens system and will focus a beam of light along a linear path of light sensitive elements representing a gauge length of a specimen or member. Flags or similar indicators that change the pattern of the light beam are mounted or marked on the specimen at two spaced loations. As the specimen is loaded, the flags will change in spacing, and, as shown, the change in the location of shadow will cause changes in the affected light sensitive elements which provide outputs that indicate displacement in the specimen. The sensing circuitry providing the output is compact and easily mounted within a module carrying the lens. The module may be mounted directly to a test specimen frame.

摘要： An optical grid analyzer automatically determines strain in sheet metal during or following a forming operation by measuring the change in radius of open circles which are stretched into ellipse patterns as a result of the forming operation. The system includes a hand-held video camera unit which produces an analog video image of one of the ellipse patterns. An interface device converts the analog image to a binary image, and then converts the binary image to a transition point image which represents the coordinates of those pixels located at an edge of the pattern. A digital computer sorts the transition point data into inner and outer edges of the pattern. The digital computer then derives major and minor radii for the outer edge and for the inner edge, and averages the inner and outer edge radii to produce average major and minor radii representing the center of the pattern. The computer then calculates strain values based upon the average major and minor radii and the radius of the undeformed circle.

摘要： A device for use in transporting and storing materials. The device includes a housing which is defined by a bottom panel and four generally planar panels extending substantially perpendicular to the bottom panel. A generally rectangular compartment is defined within those four panels which extend perpendicular to the bottom panel. Upper edges of two opposite of the panels perpendicular to the bottom panel are convexly arcuate and parallel to one another. The upper edges of the other two panels are also convex and parallel to one another. The device further includes a generally planar closure panel including a lower surface which carries a compressible seal. The seal is of a size at least as great as an area defined by the upper edges of the four panels which are perpendicular to the bottom panel of the housing. The seal cooperates intimately with the upper edges of the four panels, when the closure panel is brought into engagement with the top of the housing, to seal the compartment defined within the four panels.
