Patents by Inventor John Frederick Runyon

John Frederick Runyon 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).

  • Fluid isolator assembly and floating elastomeric damping element
    Patent number: 7178794
    Abstract: An isolator apparatus is described to attenuate or isolate vibration. The isolator apparatus includes a fluid isolator assembly including a flexible diaphragm and a pressure chamber having a flow passage opened to the pressure chamber to provide a fluid spring. A floating isolator body including an elastomeric damping element is floatably interfaced with the flexible diaphragm of the fluid isolator assembly to isolate vibration.
    Type: Grant

  • Detecting transducer position precisely with a reusable sensor assembly
    Patent number: 7023643
    Abstract: A method and apparatus for transducer position detection uses inert contact surfaces to engage an actuator temporarily. The inert contact surfaces are part of an apparatus that also includes an optical sensor such as a retroreflector or diffraction grating. The assembly is thus configured to permit multiple uses while exerting a near-zero net torque about the length of the arm that supports the transducer. This is useful where there is a temporary need for especially precise position control, such as when servowriting a data storage media surface.
