Robert A. Hiller 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).

  • Patent number: 8421306
    Abstract: Systems and methods for achieving cavitation at high static pressures which may be used in acoustic applications and research such as in liquid metal resonators. Novel preparation and electroplating methods are disclosed to improve boundary layer conditions. A chemical cleaning loop for containment and treatment for oxide removal and to develop a dynamic system for chemically treating liquid metal disposed in a liquid metal loop is also described. A liquid metal handling loop for containment and treatment is provided to maintain cleanliness of bulk liquid metal.
    Type: Grant
    Filed: July 7, 2010
    Date of Patent: April 16, 2013
    Assignee: Impulse Devices, Inc.

  • Patent number: 6688112
    Abstract: A thermoacoustic refrigeration device employs a gas-vapor mixture as the working fluid. As a result, the refrigeration device operates according to a modified thermoacoustic refrigeration cycle that adds a condensation-vaporization cycle to the thermoacoustic cycle. The resulting modified refrigeration cycle increases the efficiency of heat transport by harnessing the translational motion of the vapor, as well as the usual acoustic oscillations, to transport the heat energy from one end of a thermal stack to the other.
