Walwyn Jackson, JR. 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).

  • Leak detector
    Patent number: 9632067
    Abstract: The invention relates to a leak detector comprising a first sensor for detecting a gas component (helium) in a gas taken in. Because the sensor is susceptible to saturation or contamination, a second sensor is provided. The sensor is a thermal conductivity sensor. The thermal conductivity sensor has a lower detection sensitivity, yet, at a high concentration of the gas component, it does not risk being contaminated. The two sensors together allow for a large detection range, from extremely sensitive measurements to instances with high concentrations of the gas components as those which can occur with gross leaks.
    Type: Grant
    Filed: August 24, 2015
    Date of Patent: April 25, 2017
    Assignee: Inficon GmbH
    Inventors: Daniel Wetzig, Scott Dalton, Daniel Hoffmann, Walwyn Jackson, Jr.
