ELECTROMAGNETIC ENGINEERING. Expert has 20 years of experience in electromagnetic engineering and has acquired 10 patents in this area. He has designed or supervised the design of linear and rotary actuators, brushless DC motors, solenoid-related devices, VALVE ACTUATORs, sensors, and magnetic instruments using electromagnetic principles.

BRUSHLESS DC MOTOR DESIGN. As a former Chief Scientist of a major producer of brushless DC motors, Expert has expertise in these motors for disk drive, pump, medical, vehicle, and robotic applications.

COMPUTATIONAL ELECTROMAGNETICS; MAGNETICS. Expert has used finite element and finite difference analyses and other computational methods to solve for magnetic forces, fields, eddy currents, and more. He has also conducted seminars and taught college classes in these areas. He has written special programs for pulse effects versus time motion due to magnetic effects.

MAGNETIC DESIGN. Expert is familiar with permanent magnets, magnetizing methods, and magnetic equipment. He has designed magnetic devices and analyzed permanent magnetic fields. He has worked with magnetic lenses and focusing, magnetic clutches and brakes, magnetic clamps, separators, and instruments. He has studied permanent magnets for power generation, materials separation, position and velocity sensors, and direction detectors.

ACTUATOR DESIGN. Expert has 20 years of experience in the design of rotary and linear actuators. He has designed linear actuators for the Cray 1 supercomputer and a host of other actuators from very small (1/4-inch wide) to very large (6 ft. long stator, thousands of pounds of force).

VALVE ACTUATOR. Expert has worked on many designs of VALVE ACTUATORs for servo-valves, flow control, ultra-fast response, and minimum-energy activation.

AUTOMATIC CONTROL. He is experienced with control of machine tools, valves, disk drive head assemblies, motors, and actuators. He has studied stability, minimum access time, position, and acceleration as it relates to automatic control. He has industrial experience with control theory and active damping of vibration.

FATIGUE ANALYSIS. He is experienced with the failure of materials due to accumulated damage from stress and strain in shapes, structure, surfaces, plates and the effects of surface roughness, stress concentration, and stress history versus time as it is applied to machinery. He has taught this subject as a college professor.

PNEUMATIC CONVEYOR DESIGN. Expert has designed conveyors which move bulk materials through tubes by entrained air flow both vertically, horizontally, or in combination.

THERMAL ANALYSIS. With many years of experience in this area, Expert has studied heat flow and distribution in machines, structures, motors, and electronic devices. He understands thermally-induced stress and deformation, forced and natural convection, conduction, and radiation.

FLUID DYNAMICS. Expert is familiar with the flow of gasses and liquids and the associated drag and pressure changes due to flow.
