Patents by Inventor Evan B. Carew

Evan B. Carew 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).

  • Patent number: 5292792
    Abstract: Intrinsically conductive or semiconductive stable polyacetylides and methods of forming same. The unique soluble metallic polyacetylides may be formed as a conductive adherent film for coating glass, ceramics and metals. The polyacetylides may also be synthesized with pendant organic anions and cations for conductive or semiconductive materials, including integrated circuit subunits, printed circuit board equivalents and thin film electrodes in an organic battery. The polyacetylides may also be synthesized with organic crosslinkers forming high tensile strength polymers comparable to steel. A simultaneous polymerization initiation for forming the conductive polymers is also disclosed by which catalyst/reductant initiation and non-chemical initiation are used to initiate polymerization.
    Type: Grant

  • Patent number: 4807991
    Abstract: A method and apparatus are provided for mapping the surface morphology of an object in order to detect and repair structural defects in the object or to distinguish surface features. A beam of light having a single frequency, such as a laser, is scanned across a plurality of locations on the object's surface and the light reflected from each surface location is received and analyzed by a spectrometer and a multi-channel analyzer. The refelected light originating from the laser beam which is absorbed by the surface is shifted in frequency by an amount determined by the type and concentration of molecular bonding of the surface material. The type and concentration of bonding for each scanning location is represented by a set of binary data which are then used to generate a composite visual display of the surface in which each pixel has a color and intensity determined by the set of binary data which represent the type and concentration of bonding.
