Patents by Inventor Edward F. Romero

Edward F. Romero 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).

  • High force vibration testing with wide frequency range
    Patent number: 8408066
    Abstract: A shaker assembly for vibration testing includes first and second shakers, where the first shaker includes a piezo-electric material for generating vibration. A support structure permits a test object to be supported for vibration of the test object by both shakers. An input permits an external vibration controller to control vibration of the shakers.

  • Using piezo-electric material to simulate a vibration environment
    Patent number: 7851973
    Abstract: A target object can be vibrated using actuation that exploits the piezo-electric (“PE”) property. Under combined conditions of vibration and centrifugal acceleration, a centrifugal load of the target object on PE vibration actuators can be reduced by using a counterweight that offsets the centrifugal loading. Target objects are also subjected to combinations of: spin, vibration, and acceleration; spin and vibration; and spin and acceleration.
