Patents by Inventor Edward J. Depeters

Edward J. Depeters 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).

  • Method and compositions for preparing and delivering rumen protected lipids, other nutrients and medicaments
    Patent number: 7700127
    Abstract: This invention provides composite gels to, e.g., efficiently deliver unmodified amino acids, lipids, and/or feed supplements through the rumen of a ruminant animal. The invention also provides methods to make and use composite gels.
    Type: Grant
    Filed: July 14, 2003
    Date of Patent: April 20, 2010
    Assignee: The Regents of the University of California
    Inventors: Moshe Rosenberg, Edward J. DePeters
  • Sensor for analyzing components of fluids
    Patent number: 6733984
    Abstract: A sensor is provided that is useful for assaying a component of a biological fluid such as blood, urine or milk, and comprises a chamber having an inlet, a liquid containing portion and a vapor containing portion. The liquid and vapor containing portions are in fluid communication. A pressure monitor is in communication with the vapor containing portion and measures pressure change within the vapor containing portion, such as carbon dioxide partial pressure changes which are related to concentration of urea in blood, urine or milk when the enzyme is urease. A method of analyzing a component such as urea in a biological fluid is also provided. Where the biological fluid is dairy milk, milk urea nitrogen to a prediction error of about +/−1 mg/dl may be repeatedly measured in the physiological range of from about 6 to 24 mg/dl.

  • Sensor for analyzing components of fluids
    Publication number: 20030036052
    Abstract: The present invention provides methods and sensors for assaying components of fluid samples by measuring pressure changes. In particular, the invention provides methods to assay for components in fluids with or without the aid of enzymatic reactions. The invention also provides a modified sensor that has an immersible pressure monitor/gas-containing portion unit and is capable of detecting pressure changes with higher sensitivity.
