Abstract: A universal guide is a base of a fishing line guide assembly designed to conform to the outside radius of a round rod or to the flat surface of a rod having a polygonal cross section. The guide is preferably helical. The base has a curved top side, a segmented underside, and tips at the toes of the guide. The underside has a concave portion and a flat portion. The concave portion comprises the center of the segmented underside and extends the length thereof. The surface of the concave portion is designed to conform to the outside diameter of a round rod. The flat portion flanks both sides of the central concave portion and also extends the length of the guide foot. The surfaces of the flat portion are designed to match the outside surface of a standard fishing rod having a polygonal cross section. The guide foot tips taper the thickness of the base from the top surface to the underside enabling a smooth transition for wrapping at the guide-rod interface.

Abstract: A monitor having a hollow semipermeable casing with a test strip is agitated in a sample volume of suspect liquid. The monitor is partially filled with tiny colored beads confined to its interior by the size of the openings in the semipermeable structure. Adhered to the beads are antibodies matched to the antigen characterizing the suspect substance. The test strip is segregated into collection and control regions. Antibodies matched to the suspect antigen are adhered only to the collection region. If the sample fluid contains the suspect substance, it will bind to both the bead antibodies and the collector antibodies, resulting in an accumulation of colored beads in the collection region but not the control region. A significant color differential between the two is a positive indication of the suspect substance. This invention has significant potential in screening for the date rape drugs, GHB and rohypnol.
