  • Methods And Apparatus For Magnetic Article Detection

  • US Patent:
    7619406, Nov 17, 2009
  • Filed:
    Mar 3, 2008
  • Appl. No.:
    12/041055
  • Inventors:
    Cory Voisine - Weare NH,
    Devon Fernandez - Manchester NH,
    Karl Scheller - Bow NH,
    Ravi Vig - Bow NH,
    Kirsten Doogue - Manchester NH,
  • Assignee:
    Allegro Microsystems, Inc. - Worcester MA
  • International Classification:
    G01B 7/30
    G01R 33/00
  • US Classification:
    32420725, 324225
  • Abstract:
    Apparatus and methods for detecting passing magnetic articles using a first, True Power On State (TPOS) detector during a first time interval and transitioning to a second, running mode detector after the first time interval, when the output of the second detector is accurate. A phase comparator is responsive to the output signal of the first and second detectors and provides a control signal indicative of a change in the phase relationship between the two output signals. An output switch controlled by the phase comparator provides, as the detector output signal, the first detector output signal during the first time interval and the second detector output signal thereafter. A threshold signal associated with the TPOS detector is at a fixed level during a first portion of the first time interval and is adjusted during a second portion of the first time interval in response to an automatic gain control circuit in order to reduce the phase error associated with transitioning from the TPOS detector to the running mode detector. Also described are apparatus and methods for updating a running mode threshold signal that is a percentage of the peak-to-peak magnetic field sensor signal, so that unnecessary update events are reduced.
