Abstract: A hand-size structured-light three-dimensional metrology imaging system and method. Laser illumination stripes are scanned across a workpiece surface for obtaining z-height and x-coordinate information. A Scheimpflug configuration is used. Utilizing this configuration, a laser illumination stripe across a raised workpiece portion will be shown in a contour image at the image sensor in a focused manner, such that the offsets along the contour image line due to the raised portions of the workpiece surface can be accurately converted to a z-height measurement. The y-axis positions associated with each of the contour images, used for reassembling the information from the contour images into a surface map for the workpiece, may be determined without the need for a position sensor, by including a reference object in the contour images.

Abstract: A method and system for maximizing process capability in a progressive forming operation. The method compensates for deviations introduced by unformed components, and uses closed loop feedback to compensate for deviations introduced by forming tools. Fiducial features are detected on an incoming component, and a first compensation value is calculated from displacement of the fiducial features from an ideal forming location on the component. Component position with respect to a theoretical forming position is adjusted according to the first compensation value. Placement of a feature formed on the component at the adjusted position is detected and compared to the ideal forming location to obtain a difference value. A second compensation value is derived from a plurality of difference values. Forming positions for subsequent incoming components are adjusted with respect to the theoretical forming position according to first and second compensation values.

Abstract: The process for the on-line characterization of a surface in motion, preferably a galvannealed sheet, essentially comprises an industrial microscope associated with a stroboscopic laser illumination device, a positioning assembly, an assembly for acquiring and processing images. The obtained view fields vary between 125 ?m and 2000 ?m in width, the spatial resolution is at least 0.5 ?m, and the focussing of the system is precise to a micrometer. The images are taken on a product moving at a speed of between 1 m/s and 20 m/s and are frozen by the use of a stroboscopic illumination device with a duration of illumination of at least 10 ns. The obtained images are processed in several steps. A background average level is first of all regularly evaluated in order to be eliminated from each current image. The processed image is then divided into several zones. The sharpness of each zone is evaluated and stored in memory.

Abstract: A system for determining a three-dimensional image of an animal, or other symmetric object, by projecting a pattern of light on the object and capturing two images of the reflected light with two cameras located a fixed distance apart. Using triangulation, the x, y, and z locations of each element of the light pattern is measured, thus creating a three-dimensional image of the surface of the object. Because animals are symmetric, an image need only be taken of one side of the animal, and the image mirrored, to determine the complete three dimensional characteristics of the animal.

Abstract: A method for inspecting a reticle to evaluate the degree of corner rounding of a feature of a test pattern includes placing a reticle having a photomask formed thereon under a microscope. The photomask has a pattern corresponding to features of a semiconductor chip design defined therein. In addition, the photomask further has a test pattern and a crosshair orientation mark defined therein. The test pattern has at least one test corner for evaluating a degree of corner rounding when the test pattern is defined in the photomask. The crosshair orientation mark is defined in the photomask to orient a crosshair of the microscope relative to the test pattern. Once the crosshair of the microscope is aligned with the crosshair orientation mark, the crosshair of the microscope is used to evaluate the degree of rounding of the test corner of the test pattern.

Abstract: A system measures the three-dimensional linear, angular and volumetric characteristics of an animal or carcass, such as a beef animal. The system uses light spots from a structured light camera to measure multiple points on the animal. The system locates the vertical, horizontal and depth dimension for each point and uses this data to calculate the desired linear and volumetric measurements for conformation of the animal by combining measurements of some of the light spots projected on the animal. The system also provides rapid consecutive three-dimensional motion pictures of the animal.

Abstract: For electron beam wafer or mask processing, a registration mark is capacitively coupled to the top surface of an overlying resist layer on a substrate to form a voltage potential on the surface of the resist layer directly over the registration mark. The registration mark is directly connected to an electrical lead that produces an AC voltage on the registration mark, which is capacitively induced on the surface of the resist layer. Alternatively, the registration mark itself is capacitively coupled to a conductive plate placed on the bottom surface of the semiconductor substrate. An AC voltage is then applied to the conductive plate that induces a charge on the registration mark, which then capacitively induces a charge on the surface of the layer of resist. An electron beam scanning across the surface of the resist layer generates secondary electrons. The secondary electrons have a low energy and are affected by the voltage potential created at the surface of the resist layer.

The first element may comprise an ink jet printhead heater chip and the second element may comprise an ink jet printhead nozzle plate.

Abstract: The photogrammetrical pick up of an object with the aid of an opto-electronic solid-state surface sensor can be carried out in partial-images over a large image format if the position of the sensor in the image plane is determined by means of a reseau. This can be done by imaging at least one reseau mesh in the sensor image. After measuring the reseau points in the coordinate system of the partial-image and transforming to the nominal values in the system of the reseau, the position of the surface sensor and transformation parameters for all image points within the reseau mesh are obtained. For this purpose, the approximation position of the sensor must be known with sufficient accuracy to be able to determined the number of the reseau mesh as an unambiguous identification of the reseau points.

Abstract: Method and apparatus for effecting operations, such as punching holes in sheets of material at precise locations thereon. Each sheet has a reference marking thereon and is placed on a receiver one by one and is held in fixed position on the receiver. A T.V. camera views each sheet to detect the reference marking thereon and a visual display of the marking is produced on a T.V. monitor. Also produced on the monitor is a cross-hair grating with a coincident shaded box. The cross-hair grating is first aligned with a marking reference on a master sheet to establish a fixed relation between the cross-hair and the marking reference on the master sheet and thereby between the cross-hair and the operating system, for example, the punches for punching holes in the sheets. The master sheet is removed and the sheets to be punched are placed one by one on the receiver which is moved to align the reference marking on each sheet, as viewed on the monitor with the cross-hair grating thereon.

Abstract: An optical gauging apparatus is provided for determining the deviation of a pipe end from squareness with respect to the pipe axis. A viewing scope is placed centrally in the pipe end to be measured so as to be directed at right angles thereto, and a graduated target is centrally located in the opposite end of the pipe. Sighting through the scope, the distance R of the intersection of the line of sight from the center of the target is determined. The deviation S from squareness may then be calculated from R, D the diameter of the pipe, and L the distance of the target from the end being measured, by the equation: S=RD/L.
