Abstract:
A system for processing both a composite video television (TV) signal and a video cassette recorder (VCR) playback signal containing a combined noise canceller and comb filter (108) sharing a single delay line (1H DL) and a 3.58 MHz oscillator (424) that drives a quadrature demodulator (424, 454, 456, 458, 460, 462 and 464) for demodulating both playback chrominance signals extracted from the playback signal and TV chrominance signals extracted from the TV signal. The system also provides automatic gain control to both the composite video TV signal and the VCR playback signal.

A method and apparatus (100) for preserving audio and video presentation synchronization, i.e., lip sync, during the splicing operation by selectively deleting, if necessary, an audio/video access unit to avoid overlapping of audio/video frames in the spliced output stream.
Abstract:
The invention provides methods of performing a synthetic process in a liquid distribution system (300, 310 and 320) having reaction cells (in 320), by pumping at least one reagent into a reaction cell using an electrode-based pump (360).
Abstract:
The present invention relates to chucks and methods for positioning multiple objects, optionally for transport onto a recipient substrate. Instead of using conventional clamps that employ mechanical force, the present invention is directed to the use of a non-mechanical force such as negative pressure in a vacuum chuck, or static electricity in an electrostatic chuck as the force applied to the object held by the chuck. Further, the chuck has a layer (430) for holding the objects which are optionally subsequently transferred to a recipient substrate, the layer (430) having a configuration substantially corresponding to the configuration of the recipient substrate. In certain aspects, the present invention is directed to a chuck for positioning objects with an average width or diameter less than or equal to one millimeter, and a thickness preferably less than about 3 millimeters, such as beads used in the chemical industry. In another aspect, the invention is directed to methods which involve the use of chucks, including methods for attracting an object (450) or multiple objects, methods for positioning objects, methods for transporting objects, preferably substantially simultaneously, and methods of chemical manufacturing using the chucks.
Abstract:
The present invention provides an acoustic dispenser (1710) for propelling objects toward a substrate (1790), together with methods of use of the dispenser. The acoustic dispenser uses a source of acoustic vibration (1720) and a membrane (1760) for the application of acoustic vibration wherein the objects are propelled from the membrane to a substrate. The acoustic dispenser and the methods of the invention can be used with numerous types of objects. In some embodiments, the objects are particles in a dry powder, which can include, for example, a pharmaceutically active ingredient. In other embodiments, the objects are beads, which preferably have an average diameter of about 100-300 microns. Additionally, the acoustic dispenser can be used with more than one type of objects, for example, two types of objects such as beads and dry powder. In some instances, the acoustic dispenser further comprises a membrane (1770) for separating one type of object from the other based on size, whereby one type of object is separated from the other prior to deposition.
Abstract:
An infrared imager includes an array of capacitance sensors that operate at room temperature. Each infrared capacitance sensor is composed of a bi-material strip (110) which changes the position of one plate (100) of a sensing capacitor in response to temperature changes due to absorbed incident thermal radiation. The bi-material strip (110) is composed of two materials with a large difference in thermal expansion coefficients.
Abstract:
A monochrome cathode ray tube (CRT) yoke includes harmonic windings for correcting spot distortion. In a first embodiment of the invention, the yoke (8) includes harmonic windings in the entrance region of the yoke and harmonic windings in the exit region of the yoke. The harmonic windings (14) in the entrance region produce a barrel-shaped field for correcting spot astigmatism along the diagonals of the CRT. The harmonic windings (16) in the exit region of the yoke produce a pincushion-shaped field for correcting spot elongation along the diagonals of the CRT. In a second embodiment of the invention, the yoke includes harmonic windings only in the entrance region. A stigmator (6) includes quadrupole coils driven at low power vertical scan rates. This allows the stigmator to be positioned near the electron gun and reduces the length of the CRT. In a third embodiment of the invention, the yoke includes harmonic windings only in the exit region.
Abstract:
A system and process for true multi-image alignment that does not rely on the measurements of a reference image being distortion free. For instance, lens distortion is a common imaging phenomenon. When lens distortion is present, none of the images can be assumed to be ideal. In an embodiment of the invention, all the images are modeled as intensity measurements represented in their respective coordinate system, each of which is related to a reference coordinate system through an interior camera transformation and and an exterior view transformation. Motion parameters (16, 17, 18) determined in accordance with an embodiment of the invention dictate the position of the input frames (11, 12, 13) within the reference frame (15). A reference coordinate system is used, but not a reference image. Motion parameters (16, 17, 18) are computed to warp all input images to a virtual image mosaic in the reference coordinate system of the reference frame (15). Each pixel in the virtual image mosaic may be predicted by intensities at corresponding pixel positions from more than one image. The error measure, which is the sum of the variances of predicted pixel intensities at each pixel location summed over the virtual image mosaic, is minimized. The embodiment of the invention advantageously maximally uses information present in all images.
Abstract:
The invention provides apparatus for detecting light from, for example, closely spaced detection sites. In one embodiment, the invention provides an apparatus for measuring the amount of light emitted from or transmitted through two or more detection sites of a first set of detection sites on a planar substrate (305) while spatially resolving the measurements for each detection site of the first set, the apparatus comprising: for each detection site of the first set, an addressable source of light beam (301) directed to that detection site at a first angle; and an array detector comprising a plurality of light responsive pixels (312), wherein for each detection site of the first set there is at least one light responsive pixel that receives light emitted from or transmitted through that detection site at a second angle that can be the same as the first angle.
