摘要： The apparatus and method for measuring a small spacing down to contact uses interferometric fringe intensity calibration to calibrate maximum and minimum intensity of two or more monochromatic of quasi-monochromatic interference patterns caused by a spacing between two articles (10, 12), one of which is transparent (10). The intensity calibration is done by measuring maximum and minimum fringe intensity of each color (81, 82) while altering the spacing by at least 1/4 of the wavelength of the light or other electromagnetic radiation being used. The calibration by changing spacing allows the fringe order to be calculated for each wavelength of the radiation being used. This calibration procedure allows the maximum and minimum intensity of the radiation to be known, as well as the fringe order of the interference patterns to be calculated. With the maximum and minimum intensities and the fringe orders known, the spacing is readily calculated from the interferometric theory.

摘要： An automatic surface inspection apparatus (10) comprises a light source (12) that provides a coherent light beam (20) that is split (14) and then recombined in a prism (21) to generate an interference pattern. A cylindrical lens (26) projects the interference pattern onto the surface of a disk (30) as a line of light (50). A linear detection array (45) converts the reflected line of light into an electrical signal that has a magnitude which varies dependent upon the reflected light intensity. Defects present on the surface of the disk cause variations in the reflected light intensity manifested as differences in the electrical signal output by the detection array (45).

摘要： A positioning device (12) for a car seat (3) indicates when the car seat has been properly positioned in an automobile or on a shopping cart. The positioning device includes a paper backing (14) which is encapsulated in a plastic housing (16). The plastic housing includes a relief projection (20) in the shape of an arc. A ball (24) slides within the relief projection and against the paper backing. Printed information (30) on the paper backing indicates when the seat is in the proper orientation according to the position of the ball.

摘要： An alignment device comprises a body (10) with two reference faces at right angles. A cord (15) has one end attached to the interior of the body (10) and extends out through an aperture (17) in the body. Position sensing means are mounted in the body for sensing and indicating any deviation of the angular position of the cord (15) from a reference position relative to the reference faces. The device also includes level sensing means for levelling the device, these level sensing means being mounted in a plate (11) which is rotatably mounted in the device. The position sensing means and the level sensing means may both be mechanical, electrical, or electronic. The cord may engage with a pulley coupled to a revolution counter.
