Patents by Inventor ANDREAS M. WENZEL

ANDREAS M. WENZEL 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).

  • SYSTEM, APPARATUS, AND METHOD FOR MEASURING ION CONCENTRATION WITH A STANDARD DEVIATION CORRECTION
    Publication number: 20200249215
    Abstract: Embodiments of the inventive concept include a portable ion concentration apparatus including a controller, a storage section to store one or more data samples, an amplifier circuit, and a chemical field effect transistor (CHEMFET). The CHEMFET and the amplifier circuit can indicate a quantity of nitrate levels in a sample media or a reference media. The controller can process the indication of the quantity of nitrate levels, and generate the one or more data samples based at least on the indication of the quantity of nitrate levels. The portable ion concentration apparatus can include an in-field analysis apparatus, an in-field measurement apparatus, or an in-soil monitoring apparatus. A measurement logic section can determine an ion concentration based on a sensitivity slope M or a polynomial fit. Also disclosed is a method for measuring ion concentration with a standard deviation correction.
