Patents by Inventor Wilfried Hedderich

Wilfried Hedderich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20070278815
    Abstract: A window assembly having photochromatic properties is described. The window assembly includes a substrate being adjacent to a coating. A photochromatic film is located between the substrate and the coating, whereby the photochromatic film darkens when the window assembly is exposed to ultraviolet light.

  • Publication number: 20060209551
    Abstract: A window assembly having a first transparent area and a light emissive area. The panel includes a first transparent layer with an ultraviolet blocking layer and an abrasion layer. The light emissive area includes a light emissive layer that may be an organic light emitting display, an electroluminescent display, a polymer light emitting display or a light pipe configured to receive light from a light source.

  • Patent number: 6501970
    Abstract: Viable (HT) superconductor-based processing is disclosed comprising the controlled conversion of energy resulting from application of a (HT) superconductor to an electric, magnetic, electromagnetic and/or gravitational field, wherein the converted energy is released from a corresponding chill system in order to maintain a superconducting state of the (HT) superconductor under controlled extrinsic or boundary conditions. A closed vessel is instrumental to transform said energy once created into a mechanical work, a partial chill gas mass per operating time interval, i.e. &dgr;dmV/&dgr;t, and a partial conduction enthalpy. A corresponding chill system comprises optionally at least one aeropneumatic accumulator designed to operate at least one (HT) superconductor-based overpressure vessel or dewar accommodating at least one superconductor element immersed into a liquid chill agent such as liquid nitrogen of defined heat capacity per volume superconductor employed.
