A circuit board, for an electronic circuit having a passive circuit component, has a component region, a non-component region, and circuit wiring conductors on its surface. The component region includes a polymer composition comprising a mixture of polymer resin and filler material that, in combination with the circuit wiring conductors, forms the passive circuit component.

A magnetic core is made of a composite magnetic material having a relative permeability of between 1 and 29 at a frequency range from 20 kHz to 2.5 MHz. The composite magnetic material consists of cobalt and nickel particles having an average diameter in the range of 1 to 100 micrometers, and a polymer base binding the particles to form a core.

A method of modeling muscular tissue with active finite elements. The motion and stress-strain distribution of the muscular tissue can be predicted using interconnections of the active finite elements. Each active finite element includes a motor element and at least one passive element, such as a dashpot or spring.

In-organic fillers are modified by in-situ co-polymerization of vinyl silane and another vinyl monomer. Vinyl silane couples with the filler by Si&mdash;O bonds. The remaining vinyl groups on the surface of the treated fillers then co-polymerize with the other vinyl monomer. The modified in-organic fillers treated by the in-situ co-polymerization are subsequently used to fill the polymer matrix. Tensile and impact strength of filler-reinforced polymer composites are improved remarkably.
