Abstract: A circuit board is made from a polymer material and includes a predetermined portion which has magnetic or dielectric or resistive properties. The portion with the magnetic or dielectric or resistive properties is made first and arranging within a mold. A polymer is then applied to the mold to form a board incorporating the portion with the magnetic or dielectric or resistive properties.

Abstract: A compound for a composite magnetic material having low permeability and low loss magnetic properties includes a polymer resin bonding agent and a filler comprising one or more ferromagnetic materials. The ferromagnetic materials are Cobalt and Nickel particles having an average diameter of less than 100 micrometers. The particles are coated with a titanic coupling agent to facilitate disbursement through the resin and increase the bond strengthen between the particles and the resin.

Abstract: A composition containing a thermolabile protein admixed with a liquor waste. Also disclosed is a method of preparing such a composition which contains a protein with enhanced thermostability.

Abstract: 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—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.

Abstract: A method for studying and/or simulating mechanical properties of active structures applies a new type of element, namely active finite element through incorporation of a user-defined sub-programme into a conventional finite element code. The motion and stress-strain distribution of the active structure can be predicted using the finite element model that is constructed with the active finite elements. The active finite element is driven by a motor element that is activated by a mathematical function.

Abstract: In-organic fillers are modified by in-situ co-polymerization of vinyl siloxane and another vinyl monomer. Vinyl siloxane couples with the filler by Si—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.

Abstract: Improved approaches to provide flexibility in setting user data rates and managing delay in data transmission systems using a superframe structure and Time Division Duplexing (TDD) are disclosed. These improved approaches operate to provide intelligent insertion of dummy words (bits or bites) into a data stream to be transmitted. By inserting the dummy words, the invention is able to render codewords, symbols and superframes independent from user data rates. As a result, a wide range of user data rates are available in data transmission systems using a superframe and TDD.

Abstract: A low switching temperature PTC device. The device includes a polymeric compound including a low melting temperature polyethylene, a plasticizer, and two types of carbon black.

Abstract: A foldable rod assembly includes first and second rods of predetermined dimensions and having connecting ends with pivot holes, and a coupler unit for coupling pivotally the connecting ends. The coupler unit includes two elongate plates respectively having right and left longitudinal sides, upper and lower transverse sides, and upper and lower pivot holes disposed in symmetry to a middle line between the transverse sides. A blocking member extends transversely from the right longitudinal side proximate to the upper transverse side. Two protrusions extend from the left longitudinal side parallel to the blocking members respectively and proximate to the transverse sides.
