Harry A. Kranendonk 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).

  • Apparatus and method for improved measurements of a monitoring device
    Patent number: 9482640
    Abstract: Methods and devices for improving measurements of test meter, and in particular for detecting a presence of an electrochemical sensor or strip in the test meter and a start time of an electrochemical reaction, are provided. In one exemplary embodiment of an electrochemical system includes an electrochemical sensor, a test meter, and a circuit. The circuit is configured to form an electrical connection with the electrochemical sensor such that the circuit can detect three distinct voltage ranges. The voltage ranges can be indicative of an absence of the electrochemical sensor, a presence of the sensor that is devoid of a sample, and a presence of the sensor with a sample. Test meters, methods for detecting when a sample starts to fill an electrochemical sensor for establishing when a reaction starts, and circuits for use with electrochemical strips, are also provided.
    Type: Grant
