  • Compositions and methods for drop boundary detection and radiation beam alignment
    Patent number: 7679039
    Abstract: The invention provides an apparatus and method for determining the position of a radiation beam. The apparatus includes (a) a first reflective surface and a second reflective surface, the reflective surfaces being placed to form the reflective exterior of a wedge; (b) a first detector placed to detect radiation reflected from the first reflective surface, and (c) a second detector placed to detect radiation reflected from the second reflective surface. The method includes the steps of (a) directing a radiation beam to the reflective exterior of a wedge formed by a first reflective surface and a second reflective surface; (b) selectively detecting radiation reflected from the first reflective surface; (c) selectively detecting radiation reflected from the second reflective surface; and (d) determining the position of the radiation beam based on the difference in the amount of radiation detected from each surface.
    Type: Grant

    Date of Patent: March 16, 2010
    Assignee: The Institute for Systems Biology
    Inventors: Gerrit J. van den Engh, Peter I. Nelson
