Abstract: The present invention provides a liquid distribution system, which is useful in a number of contexts, including in accomplishing various synthetic, diagnostic and drug screening reactions. The distribution system can comprise an alpha reservoir and a beta reservoir, a first set of parallel and adjacent first and second feeder channels and a second set of parallel and adjacent third and fourth feeder channels which are offset from the first and second feeder channels, wherein (a) the first and third feeder channels are connected to the alpha reservoir via a first connector channel that is situated above or below the second and fourth feeder channels and are independent of the beta reservoir and (b) the second and fourth feeder channels are connected to the beta reservoir via a second connector channel that is situated above or below the first and third feeder channels and are independent of the alpha reservoir. The distribution system is preferably a microscale distribution system.

Abstract: An apparatus and method for controlling an instrument is provided. The device may be a cutting tool for use in surgery, or other type of device applied to transform a specific object located in a defined area. The apparatus comprises a marker having a predetermined color. The marker is applied to the specific device or tool to form a marked device. An imager generates video signals representing a color image of the defined area. A color detector processes the imager signals to detect a range of colors in the image represented by the imager signals. The range of colors includes the predetermined color. The color detector provides an output signal representing instances of signals in the detected color range. A detection mechanism processes the output signal of the color detector to provide an indication of whether the detected instances represented by the output signal conform to the marked device.

Abstract: Iris recognition is achieved by (1) iris acquisition that permits a user to self-position his or her eye into an imager's field of view without the need for any physical contact, (2) spatially locating the data defining that portion of a digitized video image of the user's eye that defines solely the iris thereof without any initial spatial condition of the iris being provided, and (3) pattern matching the spatially located data defining the iris of the user's eye with stored data defining a model iris by employing normalized spatial correlation for first comparing, at each of a plurality of spatial scales, each of distinctive spatial characteristics of the respective irises that are spatially registered with one another to quantitatively determine, at each of the plurality of spatial scales, a goodness value of match at that spatial scale, and then judging whether or not the pattern which manifests solely the iris of the user's eye matches the digital data which manifests solely the model iris in accordance

Abstract: The misregistration of kinescope panel assemblies is measured by passing UV through the shadow mask to the phosphor screen. The lighthouse optics are set for exposure of one of the three phosphor colors, such as green. The intensity of light emanating from the panel is measured for a plurality of locations on the screen, and for a plurality of incremental positions of the panel assembly with respect to the lighthouse light source. The position of maximum intensity of light emanating from the panel is recorded and used to calculate the misregistration between the phosphor screen and the shadow mask.

Abstract: A method of testing a panel assembly of a color cathode-ray tube, prior to sealing a faceplate panel of the assembly to a funnel section of the tube, detects defects in the assembly including dents and misregistration of an apertured shadow mask mounted therein adjacent to a luminescent screen disposed on the faceplate panel. The screen is exposed to radiation passed through apertures in the mask including ultraviolet but substantially excluding visible radiation, and examined for variations in color from light emitted by the screen, whereby the variations in color are indicative of defects in the assembly.

Abstract: Variations in topography and material properties of the surface layer of a body are observed in microscopic imaging using a scanning capacitance probe. The acronym SCaM identifying the process and apparatus is derived from the phrase scanning capacitance microscope. The material properties observable by SCaM are the surface-electric property representative of the complex dielectric constant of the surface material and the surface-mechanical property representative of the elastic constant of the surface material.

Abstract: A video disc is molded in an apparatus which includes a pair of opposed mold members each having a mold cavity in its surface which faces the other mold member and a stamper is mounted across the mold cavity in each of the mold members. Each stamper has on its surface a surface relief pattern arranged along a spiral path. The stampers are arranged on the mold members so that any imperfections in the mold members which may pass through the stampers and be impressed on the disc being molded are aligned with areas of the stamper which do not contain information which impacts the picture quality so that such imperfections are impressed in areas of the disc which will not adversely impact the perceived picture quality during playback of the disc.

Abstract: A synchronous pulse generator responsive to a set condition of a memory produces a burst of N timing pulses within a period of time T for each M revolutions of a video disc player turntable. The timing pulses are converted to an analog voltage for application to the vertical drive circuit of an imaging device which receives one horizontal control signal for each burst. Feedback circuitry resets the memory when the number of pulses produced reaches a predetermined value whereby each time the memory is set a raster of constant height is formed having a line resolution dependent upon selection of the parameter N. The parameter M may be independently selected for controlling an effective vertical field of view represented by the displayed image. A video signal reproduced by the player may be added to the analog voltage for producing a contourgram of a selected segment of a disc being played or used for Z-axis modulation of the imaging device for producing gray scale images.
