Title: Magnetic conveyor system
Inventor: LAPEUS DAVID J
IPC: G01N35/02
Filed: 1996-06-05
Abstract: A magnetic conveyor system for transporting test samples in tubes disposed in a sample rack having a magnetic or magnetically attractive region is described. The magnetic conveyor system includes a drive system, a magnet coupled to the drive system and movable in response to the drive system and a tray having a first surface adapted to receive the sample rack.  The magnet is spaced a predetermined distance from the first surface of the tray such that the magnet provides a magnetic force at the surface of the tray.  The magnetic force engages the magnetically attractive region of the sample rack disposed on the tray to thereby move the sample rack along the first surface of the tray in response to movement of the drive system. When the tray reaches the end of the rack it is moved onto a processing queue tray where it is available for test purposes. A barcode reader reads a bar code on each test sample as it is placed on the process queue to identify one or more tests to perform. When all samples have received the individual tests the rack exits to an output queue for disposal. When a test must be made on an immediate basis out of normal processing order a sample rack can be inserted into the process queue via a priority rack feed. In the indicated manner, testing can continue without interruption as new racks are added and completed racks removed

Title: System for displaying calligraphic video on raster displays
Inventor: PATEL JAYANTI
IPC: G09G5/20
Filed: 1996-11-28
Abstract: A system and method for processing analog XYZ calligraphic video signals for presentation as a stroke image on a flat panel LCD raster display screen by converting such signals in coordinated sets to digital data in a stroke frame buffer memory. The X and Y signals define column and row addresses in memory for storage of the coordinated Z digital color brightness data, which addresses correspond to pixel locations on the surface of the display screen to which the data is transferred to form the stroke image. By storing fractional bits from the X and Y digital data in the buffer memory along with the coordinated color intensity data a high resolution stroke image can be formed using a conventional sized buffer memory. Further, noise and clock conversion artifacts are minimized by saving the first point of each stroke line or vector and by using the X and Y fractional bits for beam shaping utilizing anti-abasing discs. The discs are a set of prestored circular intensity profiles, each covering several pixels and having their respective centers variously offset by fractions of a pixel spacing from points defining the ideal center of the stroke line to be formed. Appropriate discs are successively copied to memory in overlapped manner for each pixel, based on the location of the profile center with respect to a stroke defining point in the pixel. The data output from the stroke frame buffer is thus shaped by the disc data in presenting the high resolution, anti-aliased stroke image on the raster display screen.
