  • MAGNETICALLY COUPLED COLLECTING SYSTEM FOR FLOW CYTOMETRY AND CELL SORTER SYSTEMS
    Publication number: 20220252501
    Abstract: A collecting system with a magnetically coupled sample mover is provided for flow cytometry and cell sorter systems. The collecting system uses magnets in a driver carriage to control the position of other magnets in a follower carriage. The driver carriage can thereby control the position of the follower carriage without physically touching the follower carriage.

  • Currency note width detector
    Patent number: 5309515
    Abstract: Apparatus for accurately determining the width of a traveling document in which respective groups of LEDs are disposed along a line extending transversely of the path of document travel inwardly from points spaced by a distance greater than the maximum document width. The groups of LEDs and respective strip photodiodes associated therewith are disposed on opposite sides of the path so that a document travelling along the path partially blocks respective LEDs of said groups. The LEDs are sequentially energized one by one from one end of the group to the other. The completely unblocked energized LEDs are counted and the percent blocked of the partially blocked LED is determined to permit an accurate width measurement to be calculated.
