  • Patent number: 7324904
    Abstract: Systems and methods are provided for detecting the potential of a wood sample, such as a board, to stay on grade, i.e., resist warp, after it is put into service and/or its moisture has re-equilibrated with the surrounding environment. The systems and methods include various sensor technologies and subjection of obtained data to various models, algorithms, and/or other mathematical formulas.

  • Patent number: 6833250
    Abstract: This invention provides novel methods for the detection of chitinous contaminants of non-chitinous biological materials. The methods are accurate, highly reproducible, rapid and relatively inexpensive. The methods are well suited to commercial applications, particularly in the food and agriculture industry where biological materials (e.g. food products) are regularly screened for contaminants (e.g. insect, mold, fungus, etc.). In one embodiment, the methods involve contacting a biological sample with a probe that is a lectin that binds chitin, contacting the sample with a pectinase; and detecting binding of said lectin to a chitin where the binding indicates the presence of chitin in the biological sample.

  • Publication number: 20040031716
    Abstract: This invention provides a novel packaging system comprising a packaging frame and one or more suspension membrane suspended from the frame, which membrane comprises a flexible membrane material that forms a pocket area shaped to accept an item. The shape of the pocket area allows the area to be self-sizing to accommodate irregularly shaped objects and a variety of sizes in the same package. The flexible pocket area also minimizes pressure points on the packaged item and keeps the item from contacting other items or potentially damaging surfaces.

  • Patent number: 5544813
    Abstract: A cartridge for use in a spray system, and for releasable connection to a quick-release coupling to form a nozzle assembly. The cartridge includes a generally elongated and hollow body member having a proximal end and a distal end. A nozzle tip is retained at the distal end of the cartridge, and the proximal end is adapted to fit, at least in part, within the quick-release coupling. The body member includes a shoulder for retaining the nozzle tip. In a basic embodiment, the cartridge includes a generally hollow tubular spacer which fits, at least partially, inside the body member, for pressing the nozzle tip against a shoulder formed by the body member at the distal end. An O-ring is disposed between the shoulder and the spacer, in order to seal the cartridge and to prevent leakage. A screw fits within the proximal end of the body member for retaining the spacer in tight engagement with the nozzle tip.

  • Patent number: 5442552
    Abstract: A robotic cultivator is provided for automatically positioning cultivation tools relative to a centerline of a plant row. The cultivator comprises a video camera for gathering visual information about plants in a plant row. A frame grabber is then utilized to generate a digitized image of the visual information. A computer then manipulates the visual information to determine a centerline of the plant row. Finally, a positioning device moves the cultivation tools based upon the current position of the tools with respect to the centerline.
