REPRESENTATIVE PATENTS 

6,597,177      Through Casing Resistivity Measurement In Permanently Installed Downhole Production Environment.   A tool installed within a well casing that can saturate a portion of the casing with magnetic flux and send an oscillating magnetic flux that can be used for resistivity measurement of the adjacent geologic formation. 

6,630,831      Measurement of Electrical Properties Through Non Magnetically Permeable Metals Using Directed Beams and Magnetic Lensing.   The tool “sees” through the well casing by saturating a portion of the casing will magnetic flux, thereby creating a “metallic transparency”.  The tool may also send a low frequency oscillating magnetic signal through a non permeable material such as stainless steel or aluminum.  The patent also teaches altering the concentration of the saturation flux, the frequency of the transmitter flux, placement of the transmitters and receivers or altering the orientation of the transmitter in relation to the saturation coil the depth of penetration into the geologic formation can be adjusted. 

6,657,440      Propagation of Waves Through Materials.   The patent teaches a method for creating a transparency in a material comprising the steps of creating a first electromagnetic wave adjacent to the material, saturating the material with the first electromagnetic  wave, creating a  second electromagnetic wave  having a frequency higher than the first electromagnetic wave, engaging the second electromagnetic wave with the material when the material is fully or partially saturated for creating a transparency in the material with respect to electromagnetic waves.  

6,744,263      Apparatus and Method for the Measurement of Electrical Properties of Materials Through Non-Magnetizable Materials.   The patent teaches a method to calculate the thickness of a material with unknown permeability and conductivity using transparencies.  The method includes a first step of creating a first set of electromagnetic waves having a specific constant amplitude of a known frequency, the first set of electromagnet waves for engaging a system, impinging the first set of electromagnetic waves on the system under investigation, nulling the system, receiving a nulled signal, creating a change in the system, and receiving a modified signal associated with the change from the nulled signal such that the modified signal contains sufficient information to determine the change in the system.  

6,931,309      Motor Vehicle Operating Data Collection and Analysis.   Data collection method and algorithm for computing a driver safety rating.  The invention utilizes data collected on a manufacturer installed on board diagnostic system.  The invention may also use a GPS system. 

7,114,874  Security Barrier (allowed application) for a gas generator powered cylinder and piston combination that raises a barrier from a horizontal position to a deployed position (wherein the barrier forms an acute angle to the ground). 

7,048,467 for a Security Barrier utilizing a sensor component that can detect objects moving across the ground proximate to the barrier component. 

7,101,112   for a Security Barrier  wherein the barrier is in a substantially horizontal position, a gas generator activates movement of a component from a cylinder.  The component is attached to one end of a barrier component and the barrier component is pushed upright (substantially vertical) from the original horizontal position.

7,052,567      Inflatable Heating Device.    Repair tool for in situ pipe repair with an inflatable bladder containing carbon fibers for resistive heating of a thermally responsive resin. 

7,073,536      Lateral Interface Device.    A repair tool for lining the junction or interface of two pipes.  The tool contains a housing holding an inflatable bladder and repair lining.  The bladder and lining can be inflated and extended out of the housing into the lateral pipe.   The inflated bladder presses the liner to the pipe wall and conductive wires in the bladder cure the resin within the repair material.   

7,135,087     Apparatus and Method for the Repair and Stabilization of Underground Pipes.    Method includes placing an inflatable and electrically heatable bladder within a pipe to be repaired.  The bladder can be installed with a repair liner.  Thermally  responsive chemical reactants can be injected into the ground proximate to the pipe.  Heat from the bladder can cure the chemical reactant, thereby sealing the pipe from the inside and outside.

7,245,041   Ocean Wave Energy Converter.  Method and apparatus for generating energy from mechanical motion of buoyant objects in water moving against a stable suspended float mechanisms.

7,418,197 Back Light Screen for Chroma-Key Photography.  Device for back lighting a green screen with a surrounding back enclosure.  Invention allows uniform lighting of the background green screen for composite photos.

7,444,810 :Lever Operated Pivoting Float with Generator. The invention is a pivoting float that transforms the rise and fall of ocean waves to different forms energy where the pivoting float is attached to an end of a lever arm in a first vertical position and wherein the lever arm can change from a vertical position and and float be submerged in the ocean; a spring returns the lever arm to its first position and a center opening of the float allowing passage of a second end of the lever arm.

7,468,072 Endovascular Balloon Graft.  This device is implanted in the brain and remedies occlusions or bridges aneurysms.

Tear Cord For Jacketed Tube.  This invention has been allowed. It pertains to a tear cord installed under covering jacketed around a metal tube.  The tube can convey fiber optic wires or can convey liquids.  The cables are used in downhole well applications.

I have successfully registered several trademarks during the last 6 month as well as registered several copyrights.
