  • Method for sensing levels of conductive liquids
    Patent number: 7490513
    Abstract: A liquid level sensor comprises a plurality of electrodes arranged in a defined relationship with respect to a container filling trajectory, a signal generator coupled to one or more of the plurality of electrodes, a signal receiver coupled to one or more of the plurality of electrodes, and a sensing circuit coupled to at least one of the signal generator and signal receiver. The sensing circuit is configured to produce an output indicative of electrical resistance between at least one pair of the plurality of electrodes. The sensing circuit may be associated with the signal receiver and/or with the signal generator.
    Type: Grant
    Filed: May 10, 2007
    Date of Patent: February 17, 2009
    Assignee: Vertex Pharmaceuticals, Inc.
    Inventors: Philip E. Salzmann, Alec T. Harootunian, Michael P. Emery, Javier H. Flores, Todd N. Bennett, Minh Vuong
