Patents by Inventor David Parkes Matzinger

David Parkes Matzinger 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).

  • Patent number: 6913668
    Abstract: Electrochemical test strip cards that can be singulated to produce electrochemical test strips are provided. The electrochemical test cards are made up of two or more electrochemical test strip precursors, where each precursor is characterized by the presence of a dry reagent housing reaction chamber bounded by opposing electrodes. In gaseous communication with each reaction chamber of the card is an integrated desiccant. Also provided are methods of using the subject electrochemical test strips cards, as well as kits that include the same. The subject test strips and cards find use in the detection/concentration determination of a number of different analytes, including glucose.
    Type: Grant

  • Patent number: 5780304
    Abstract: A test strip is provided for having liquid applied thereto and for determining the presence or quantity of an analyte in such liquid. Specifically, the test strip comprises a reaction zone which varies in reflectance as a function of the quantity of analtye present in the applied liquid. The strip is to be inserted into an optical reading apparatus. A standard zone is positioned on the strip so as to lead the reaction zone as the strip is inserted into the reading apparatus. The apparatus may then be provided with optical means for sequentially determining the reflectance value of the standard zone as the strip is being inserted into its fully inserted position in the apparatus and the reflectance value of the reaction zone after the strip has been inserted. The apparatus is further provided with means for calculating the presence and/or quantity of analyte in question as a function of the standard zone reflectance and the reaction zone reflectance.
