A variable inductor comprises one or more magnetic cores providing magnetic flux paths. An inductor coil is wound around one or more inductor sections of the one or more magnetic cores. An inductor magnetic flux flows through one or more closed flux paths along the inductor sections of the magnetic core. A control coil is wound around one or more control sections of the one or more magnetic cores. A control magnetic flux flows through one or more closed flux paths along the control sections of the magnetic core. Under this arrangement, the inductor magnetic flux substantially does not flow through the control sections of the magnetic core and the control magnetic flux substantially does not flow through the inductor sections of the magnetic core. The closed flux paths associated with the inductor magnetic flux and the closed flux paths associated with the control magnetic flux share one or more common sections of the magnetic core not including the control sections and inductor sections. The inductance of said variable inductor is varied by varying said control magnetic flux.       Recently Added Patents Method and device for padding optimization of segmented turbo codes Management device and management method Semiconductor memory device Electroencephalogram interface system, electroencephalogram interface apparatus, method, and computer program Method and device for sending transmission signal, in particular mobile radio signal Memory built-in self test (MBIST) circuitry configured to facilitate production of pre-stressed integrated circuits and methods Laser scanner   Randomly Featured Patents Belt pack Aqueous fatty quaternary amine-containing carrier systems for water-insoluble materials Electronic controls for linear and rotary actuators Human spinal disc prothesis with hinges Updating an engine using a description language Device for determining kind of load on seat, seat, and bio-signal detector Semiconductor memory device Copy stacking tray System and method for protecting a bodypart Challenge/response security architecture with fuzzy recognition of long passwords © 2006-2008 PatentGenius.
