  • Patent number: 7653219
    Abstract: A system for recording and analyzing lighting attributes associated with a calibrated target device captured within an image to provide for enhanced object recognition within the captured image. A target device is used to provide lighting information relative to a subject within the image. The attributes allow the lighting conditions at the time of the image capture to be reconstructed. In addition, two or more target devices may be use to triangulate the position of a light source to any point within the captured image. Further, the lighting attributes may be used to create a contour mapping of the subject captured within the image.

  • Patent number: 5638973
    Abstract: A collapsible agricultural storage container having a base, and a plurality of side panels removably connected to the base panel and interlocked at their edges by elongated, removable corner members. Each side panel is adjacent to two other side panels, and each side panel has first and second edge portions having a key member extending therefrom. Each corner member has a pair of keyways that slidably receive the key members of adjacent side panels to interlock the side panels together. The side panels include a top edge portion having an aligning rail extending upwardly away from a stacking support for alignment of an upper storage container stacked atop a lower storage container. Each side panel also has a bottom foot portion that extends below the base panel and slopes inwardly of the aligning rail to a position directly below the stacking support.

  • Patent number: 4674400
    Abstract: A self-contained, self-storing, compact hot beverage brewing device including a base member (2) including the heating and control elements, a water receiving container (6) which also serves as part of the storage container, a brewing element (10) movable from a position exterior to (6) during the brewing operation to a position interior of (6) in the storage operation and a brew receiving cup (14) which in the stored condition is placed over the top of (6) making a compact self-storing package. The brewing element (10) allows the user to by means of selector valve (12) control the strength and quality of the resultant beverage.

  • Patent number: 4578897
    Abstract: A plant watering and/or feeding unit automatically and periodically dispenses water as needed. As assembled, an air tube extends essentially throughout the central length of a selected plastic bottle and beyond the other wise sealed cap entry of this plastic bottle for insertion of the extending, first heat sealed then partially cut opened, air tube end, down through the soil without being blocked by any entering soil, to contact the bottom of the earth filled plant container. A liquid orifice is located in the plastic bottle in its shoulder about midway between the entry and the side of the bottle.During plant watering and/or feeding cycles, liquid drips from the liquid orifice in the shoulder, until the water table in the soil, i.e. the liquid level in the soil, rises above the end of the partially opened air tube to seal off the entry of air. Then the dripping of liquid stops, until this liquid level goes below the end of the partially opened air tube.
