Abstract: A tensioning system for articles of footwear and articles of apparel is disclosed. The tensioning system includes a tensioning member that is tightened or loosened using a motorized tensioning device for winding and unwinding the tensioning member on a spool. The tensioning system may be used with various sensors to determine how the motorized tensioning device should be controlled.

Abstract: Most of the present knot tying devices require the mechanical or manual sliding of the leader or line from some object such as a nail or tube onto a leader or line. This invention does not require such a transfer. The Fisherman's Knot Tier in accordance with the present invention looks and works similar to a retractable ballpoint pen with an alligator clip or modified alligator clip/cutter attached. When a line is placed in the exposed slot in the shaft, and the shaft is retracted into the tip, cone or insert, the line is secured. The jaws of the alligator clip or modified alligator clip/cutter holds the hook or similar article during the knot tying operation. The cutter portion of the clip/cutter is used to trim excess leader or line from the hook or similar article after the knot tying process is complete. The jaws of the alligator clip or modified alligator clip/cutter also doubles as a clip to hold the knot tier in a shirt or vest pocket.

Abstract: This invention pertains to the reduction of air drag on trucks and truck tractor-semitrailer combination vehicles when they are driven on open highways. It consists of a short thick airfoil mounted by struts above the cab of the using vehicle. The airfoil is made by forming upper and lower surface skins by conventional means of metal or plastic and joining them with internal ribs. Metal or plastic struts are used to adjustably attach the airfoil to and above the cab of the using vehicle. This invention uses both the upper front and the lower rear surface of the airfoil to create air flow patterns which result in reduced air drag. This invention may be used with vehicles of different sizes and may also be oriented so that it does not increase air drag when used on a truck tractor which is either traveling with no semitrailer or is coupled to a low or flat-bed semitrailer.

Abstract: A switch assembly for sensing velocity of airflow along an airflow path and having a vane for disposition in the airflow. The vane is pivoted in a case of framework and rotational movement of the vane about the pivot axis actuates a magnetic reed switch mounted within the framework. A variety of weights are provided for attachment to the side of the vane opposite the side upon which the airflow impinges for providing a variety of unbalance torques to the vane which are counter to torque produced by airflow impingement. A consequent variety of airflow velocity switching points may be obtained. For airflow paths which are small in cross section, the pivot axis of the vane may extend parallel to the cross section and the angle through which the vane may move approaches 80.degree. from the plane of the cross section so that a minimal surface of the vane will oppose airflow through the path.
