  • Robot prealigner
    Patent number: 5456561
    Abstract: An alignment station for elements such as semiconductor wafers on a robot arm uses a rotating support and edge detector which in combination are operative to place a wafer on the rotating support, detect wafer alignment, move the wafer to bring it into alignment either on the rotating support itself or onto a separate station.
    Type: Grant
    Filed: July 12, 1994
    Date of Patent: October 10, 1995
    Assignee: ADE Corporation
    Inventors: Noel S. Poduje, Roy S. Mallory

  • A.C. capacitive gauging system
    Patent number: 4918376
    Abstract: A compensated capacitive probe system in which the probe and a guard ring are placed in the feedback path of an operational amplifier. An input signal is applied to the operational amplifier in combination with a portion of the guard signal. The resulting configuration compensates for stray capacitance at a measuring electrode of the probe and for the fact that the operational amplifier is other than mathematically ideal.
