Eric Cowden 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).

  • PROTEOLYTIC DIGESTION OF CARDIAC TROPONIN I
    Publication number: 20200031889
    Abstract: A fluid sample container comprising a protease, when a sample fluid is placed in the fluid sample container the protease breaking a target analyte in the sample fluid into at least two peptides, the at least two peptides being smaller than the original target analyte.
    Type: Application

    Applicant: Siemens Healthcare Diagnostics Inc.
    Inventors: David Ledden, Eric Cowden
  • Non-contact micro droplet dispenser and method
    Patent number: 10486152
    Abstract: A liquid deposition system comprises a liquid delivery assembly including a dispensing probe having a sidewall including a first end having a liquid port and a second end having a tip, and a flow path opening at the tip and fluidly connected with the liquid port. The system includes a gas injection assembly with a manifold having a gas nozzle, a nozzle opening, and a gas port, the gas nozzle configured to eject a substantially laminar gas stream so that the gas stream travels through a travel path, the tip of the dispensing probe extending into the travel path. The liquid port is fluidly connectable with a liquid source and the gas port is fluidly connectable with a pressurized gas source, so that a liquid micro droplet is formed at the tip. The laminar gas stream separates the micro droplet from the tip and carries it through the travel path.
