  • ANGLE OF ATTACK SENSOR WITH ROTATABLE AIRFOIL
    Publication number: 20180136249
    Abstract: An angle of attack sensor includes a vane that is freely rotatable to align with a direction of an oncoming airflow over the vane. The airfoil includes a root proximate a vane hub that connects to a rotatable shaft, a tip opposite the root, a leading edge, a trailing edge opposite the leading edge, a first lateral face, a second lateral face, and a heating element disposed within the airfoil between the first and second lateral faces proximate the leading edge. The first lateral face extends from the leading edge to the trailing edge. The second lateral face is opposite the first lateral face and extends from the leading edge to the trailing edge. The first and second lateral faces are symmetric about a chord of the airfoil and each have an outer surface profile that is nonlinear and geometrically convex from the leading edge to the trailing edge.

  • Mechanism for dynamically varying blade load over a windshield wiper sweep cycle
    Patent number: 9517751
    Abstract: A wiper arm assembly has a load member, a wiper arm, and a blade load cam with a cam slot. The load member mates with a joint disposed between first and second ends of the wiper arm. Changes in length of the load member impose a force in a lengthwise direction of the load member. The wiper arm is configured to rotate relative to the blade load cam about an axis proximate to the first end of the wiper arm. The cam slot is configured to vary the length of the load member as a function of a wiper angle in which the wiper angle is defined as the angle between the wiper arm and a starting position of the wiper arm.
