Resistance Inductance Capacitance Technology

A variable resistance inductance capacitance (R-L-C) technology electrically controls a mechanical movement device (e.g., linear positioner, rotary motor, or pump) that selectively controls an electrical element to vary, and maintain at a selected value, its electrical resistance, inductance, and/or capacitance. The method uses an electrical signal to automatically move a portion of the electrical component in relation to another portion (to vary at least one of its parameters) by using a non-magnetic mechanical movement device. Its components are compatible with and function in high fields (such as a magnetic field of one tesla or more, or even ten tesla or more and/or an electric field of many thousands of volts per meter).

Compatible with High Magnetic and Electric Fields

Conventional electrical components that vary resistance, inductance, and/or capacitance under electrical control typically have somewhat limited component values available and are not compatible with being located in high fields (e.g., the fields of 1 tesla or more, typically found in high-energy physics experiments). Low-power circuits use varactors, field-effect transistors and directly electrically-adjustable components for adjusting frequency, impedance or other circuit characteristics and parameters, but such components are often unsuitable or inoperative in high fields. This technology provides a variable-parameter electrical component in a high-field environment and, based on an electrical signal, automatically moves a movable portion of the electrical component in relation to another portion to vary at least one of its parameters.

BENEFITS AND FEATURES:

  • Electrically controls a mechanical movement device (e.g., linear positioner, rotary motor, or pump)
  • Selectively controls an electrical element to vary—and maintain—its electrical resistance, inductance, and/or capacitance.
  • Compatible with high fields (e.g., magnetic field of one tesla or more, ten tesla or more, and/or an electric field of thousands of volts per meter)

APPLICATIONS:

  • High magnetic fields
  • Resistance, inductance and capacitance (R-L-C) technology
  • Linear positioners
  • Rotary motors
  • Pumps
