  • Patent number: 8216439
    Abstract: The invention provides novel a hybrid slip casting-Electrophoretic Deposition (EPD) process which can be used to produce arbitrary shape geometries with controlled materials properties. The invention provides processes for the fabrication of Functionally Graded Materials (FGM) by a controlled Electrophoretic Deposition (EPD).
    Type: Grant
    Filed: February 2, 2007
    Date of Patent: July 10, 2012
    Assignee: San Diego State University (SDSU) Foundation
    Inventors: Eugene Olevsky, Xuan Wang, Margaret Stern

  • Patent number: 7124928
    Abstract: A micro-optical train manufacturing process includes a step of characterizing the position of optical components on an optical bench, typically using a metrology system. These optical components are then aligned with respect to each other in a passive alignment step based on data from the metrology system and optical system design information. As a result, a subsequent active align process can be avoided in some situations, or if a subsequent active alignment process is performed, the time required for that active alignment process can be reduced because of this initial metrology-based passive alignment step.
