  • Film based addressable programmable electronic matrix articles and methods of manufacturing and using the same
    Patent number: 7220344
    Abstract: An electronic device adapted for performing molecular biological processes. The device includes a flexible polymeric substrate having a first surface and a second surface. A plurality of microlocations interrupt the first surface, and each of said microlocations include an electrode disposed on the second surface of the flexible substrate. A hydrophilic matrix is positioned on the first surface of the flexible substrate and is capable of electrical contact with the electrode.
    Type: Grant

  • Lawnmower blade with replaceable knives
    Patent number: 5839263
    Abstract: A lawnmower blade with replaceable knife members (40) mounted on the leading edge of a rotating blade body wherein the entire assembly to a rotating shaft of a lawnmower or the like. The knife member (40) is manufactured from carbides, high speed steels, or powder metals, thus producing a cutting edge with high quality and durability. Knife member is attached to a rotating body in either a safety cage assembly (100) or embedded in the body of the blade. The knife member is retained on the blade body and can be rotated to a fresh sharp edge or replaced.
