Abstract: A device that attaches to a predetermined portion of a pressure distributing superstructure of a windshield wiper blade assembly on a vehicle for preventing a flexible blade of the assembly from lifting off the windshield of the vehicle when it is traveling at a relatively high speed. The device includes an airfoil member having a substantially flat first portion and a laterally extending substantially concave second portion for deflecting high speed airflow and producing an aerodynamic force downward onto the superstructure pushing the blade against the windshield. There are a pre-selected number of elongated clip members that are affixed to a bottom surface of the first portion of the airfoil member, each including at least one protruding portion that is engageable with the superstructure of the assembly for clipping the airfoil member thereon.

Abstract: An oral nighttime appliance consists of a somewhat resilient U-shaped base substantially complementary with a person's dental arch. At least one integral lip protrudes from anterior edges of the U-shaped base, and a substantially rigid hourglass-shaped flap is connected into and partially spanning the gap between the posterior legs of the U-shaped base, and protrudes rearward and downward. A second flap, nearly semicircular and rigid, extends rearward and upward from the posterior of the base into which one end of the second flap is secured.
