Patents by Inventor Christopher McIntre

Christopher McIntre has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • pH and concentration meter
    Patent number: 5198093
    Abstract: The present invention comprises an electrochemical metering apparatus that provides for convenient storage and presentation of the analytical electrode, simple assembly, and two calibration modes. The apparatus includes an electrode storage and presentation assembly that permits the user to introduce the electrode into a sample solution while simultaneously observing the meter's output, and store the electrode when not in use. All structural components are intended to fit together with interlocking tabs and windows. A serial port fits within the construction of the main housing without the need for bolts, and battery clips that depend directly from the circuit board obviate the need for wiring connections. The present invention also features two calibration modes. A "segment addition" mode permits separation of the voltage/concentration curve into individually plotted regions, the number of which depends on the number of reference solutions used in the calibration procedure.
    Type: Grant
    Filed: January 17, 1992
    Date of Patent: March 30, 1993
    Assignee: Orion Research, Inc.
    Inventors: Paul Sydlowski, Steven West, Chin-I Shyr, Christopher McIntre, Jeffrey S. Cohen, James Barbookles, Loren Somes, Thomas Paquette, Laura Brockway
