Abstract: A open cockpit kayak is provided including an improved thighstrap arrangement. The arrangement includes left and right thighstraps situated on respective sides of the cockpit area and extending in the longitudinal direction of the hull. Opposite ends of each thighstrap are movably connected to the hull at respective fore and aft connection locations. Each of the thighstraps includes an elastic element to maintain it in tension between the respective fore and aft connection locations. As a result, the thighstraps will generally remain taut against the hull when not in use. Further, the thighstraps will remain in engagement with a paddler's knees during use so that the paddler may easily achieve positive control of the kayak.

Abstract: For circuitry having analog and digital circuit sections and a signal flow path therebetween, a guard crossing for establishing electrical isolation and virtually no capacitive coupling between the two sections comprises optical fiber cables extending between circuit boards or between partitioned regions of a common circuit board carrying the analog and digital section for interfacing signals therebetween. Electrooptical transmitters and receivers in each section are coupled to the optical fiber cables. In accordance with one embodiment, bit serial signals are transmitted between the analog and digital sections through a single optical fiber cable for each direction. In another embodiment, a plurality of optical fiber cables for each direction carry the parallel bits of bit parallel signals between the two sections.

Abstract: A display unit comprising an elongated tray with walls which define a region accommodating a batch of sachets, the tray including longitudinal side walls with inwardly turned parts at each end, the said parts being capable of providing support for another display unit placed above.
