A metrology apparatus has an illumination source that directs collimated light to a reference surface and to an optical component having a test surface that is in parallel with the reference surface. A first imaging lens defines a Fourier transform plane for light reflected from the reference surface and the test surface. A spatial filtering element is actuable to a blocking position that blocks specular light at the transform plane. A second imaging lens forms, at an image plane, an image of the test surface. A sensor array generates image data from received light at the image plane.

A system includes a plurality of semiconductor processing tools; a carrier purge station; a carrier repair station; and an overhead transport (OHT) loop for transporting one or more substrate carriers among the plurality of semiconductor processing tools, the carrier purge station, and the carrier repair station. The carrier purge station is configured to receive a substrate carrier from one of the plurality of semiconductor processing tools, purge the substrate carrier with an inert gas, and determine if the substrate carrier needs repair. The carrier repair station is configured to receive a substrate carrier to be repaired and replace one or more parts in the substrate carrier.

A screeding system for use with a screeding machine during screeding of an uncured concrete surface includes a control and a plurality of sensors. The sensors are disposed at the screeding machine, which has a screed head assembly that is movable over uncured concrete to screed the concrete surface. The sensors include elevation sensors that sense an elevation of the screed head assembly relative to a reference plane established at the concrete area. The control processes data captured by said plurality of sensors while the screeding machine is screeding the uncured concrete surface. Responsive to the data processing of captured data, the control estimates a flatness or levelness or quality of the surface of the concrete being screeded. While the screeding machine is screeding the uncured concrete surface, the control generates an output indicative of the estimated flatness or levelness or quality of the surface.

A method and device recognize and analyze surface defects in three-dimensional objects having a reflective surface, in particular motor vehicle bodies. In which method the surface defects are identified by the evaluation of an image, recorded by a camera in the form of a raster image of pixels, of an illumination pattern projected by a first illumination device onto a part of the reflective surface using a two-dimensional raster coordinate system. The surface defects are identified exclusively using two-dimensional image information with the aid of image processing algorithms without the need for “environmental parameters”, and complex geometric calculations can be omitted. The solution is fast and robust and can be carried out using differently configured first illumination devices, which makes it suitable for mobile applications, for example as a hand-held module. It is also made possible for the method to be optimized by a “deep learning” strategy.

The machine includes a rotational mounting bracket, upon which an agricultural disc is supported and held. A hold-down plate that can rotate freely is arranged above the mounting bracket. A linear actuator displaces the hold-down plate vertically in a downwards direction to press the agricultural disc. A laser measurement device is coupled to a linear guide where the hold-down plate forms part of a rotational head-piece fixed to a rod of the linear actuator. A method includes determining a central reference height on a model disc, determining the height of points in the periphery of the disc to be measured, calculating the average of the measured heights and comparing with the central reference height to determine whether the disc is valid or not.

An automatic analysis device and method having a BF separation process, wherein the width in a container conveyance direction of a surface facing a reaction container of a magnet for preliminary magnetic collection of a first magnetic generation part (32p) is set to have a length including a region for housing a liquid sample of the reaction container conveyed to a magnetic collection position of the first magnetic generation part. An end in the container conveyance direction of a surface facing the reaction container of a magnet for regular magnetic collection of a second magnetic generation part (32m) is designed to be close to the center of the region for housing the liquid sample of the reaction container conveyed to a magnetic collection position of the second magnetic generation part.

A communication device includes a communication control unit generating a communication signal to be transmitted to an external source and an encryption unit connected to the communication control unit through a wiring. The communication control unit stores a predetermined communication signal indicative of a predetermined message and a target duration required for from a transmission of the predetermined communication signal to a reception of the same from the encryption unit. The communication control unit further counts an actual duration taken from the transmission of the predetermined communication signal to the reception of the same from the encryption unit. When the actual duration is longer than the target duration, the communication control unit determines that a fraudulent circuit is inserted into the wiring for fraudulently acting on the communication signal.

To carry out evaluation of a road surface property easily and in a short period of time without being costly. Measurement data of a road surface measured for a predetermined road width along a path of a road to be measured is acquired; a unit area having a preset length dimension along the path in the road width is set along the path; a model plane in the unit area is set based on the measurement data at each point in the unit area; point group data is generated from a spaced amount of the model plane and each point in the unit area, visualize and display the spaced amount in the path, and display a result of evaluation obtained through statistical processing with the path shown on a map.

The present invention comprises a surface to maximize the viewing of an impression in a vehicle body. This may comprise a fabric which has at least one dark colored stripe parallel to at least one light colored stripe; a compressible frame across which the said fabric is affixed, where when the frame is uncompressed the fabric is stretched taut across the frame and where the frame is compressed the fabric is slack across the frame; and a handle on the frame where a user can hold the frame and not interfere with the fabric affixed to said frame. When a user is holding the handle of the frame at an angle between 0° and 180°, the user can reflect radiant energy through said fabric onto the vehicle body and create a whorl reflection pattern on the impression to maximize viewing of said impression by the user.

An information processing apparatus includes an acquisition unit configured to acquire a plurality of captured images of a traveling surface where a movable apparatus travels, each of the captured images including distance information in a depth direction transverse to the traveling surface, the plurality of captured images having been captured using a plurality of stereo image capture devices, and an image processing unit configured to stitch together the plurality of images of the traveling surface captured by the plurality of stereo image capture devices by identifying partially overlapping portions of one or more pairs of the images captured by respective stereo image capture devices which are adjacent in a width direction of the traveling surface.
