Jeffery Bush 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).

  • All fiber autocorrelator
    Patent number: 6847453
    Abstract: An autocorrelator apparatus and method for economically measuring physical properties of an object where the measurement path is at least semi-translucent to light, such as thicknesses in multilayered optical structures, group index of refraction, and distance to a surface. The apparatus includes a non-coherent light fiber interferometer and an optional coherent light fiber interferometer in association so as to share PZT fiber modulators. Thickness and boundary extent measurements can be made, for example, of solids, liquids, liquids moving along a horizontal plane, or liquids flowing down a plane.
    Type: Grant

  • Landscape fence cover
    Patent number: 6719276
    Abstract: A fence cover for improving the appearance and function of preexisting fencing that is formed of rigid panels having an outer face provided with aesthetically pleasing color or indicia. The indicia may depict a landscape or simulate other fencing styles.

  • Demodulator and method useful for multiplexed optical sensors
    Patent number: 5903350
    Abstract: An apparatus and method is presented to provide wide dynamic range measurements of the input phase to an interferometer using a phase generated carrier especially useful utilizing time multiplexing to demodulate a series of interferometers. A modulation drive output is provided by the invention and maintained under operation at the optimum amplitude by an internal feedback loop. The resulting highly stable system can be fabricated from an analog to digital converter, a digital signal processor, and a digital to analog converter making low cost open loop demodulators a reality.
