    Abstract: An alignment device includes a first body and a second body, at least one retention member flexibly coupled to the first body, and a locking member coupled to the first body. The second body has an outer surface and an inner surface defining a cylindrical wall, the cylindrical wall defining a cylindrical opening, a first retention opening extending through the cylindrical wall and a second retention opening extending through the cylindrical wall. The first body translates within the cylindrical opening of the second body and the locking member engages with the first retention opening to position the alignment device in a first position and the locking member engages with the second retention opening to position the alignment device in a second position.

    Abstract: An extendable windshield wiper system includes a wiper blade assembly having: a resilient material wiper blade; and a wiper extension rod connected to the wiper blade. A wiper sleeve is configured to move about an arc of rotation with respect to an axis of rotation of the wiper sleeve. A bore of the wiper sleeve has the wiper extension rod slidably disposed within the bore. An actuation portion directs a pressurized fluid to outwardly extend the wiper extension rod from the wiper sleeve and thereby to outwardly extend the wiper blade in an extension direction during a first portion of the arc of rotation. The wiper blade is induced to traverse an extended arc of travel during rotation of the wiper extension rod and the wiper sleeve along the arc of rotation.

    Abstract: A beltline reinforcement member for a door of a vehicle includes a body that extends along a longitudinal axis, between a first end and a second end. The body includes, an inner belt wall extending generally parallel to the longitudinal axis, an outer belt wall extending generally parallel to the longitudinal axis and spaced apart from the inner belt wall for receiving a window between the inner belt wall and the outer belt wall, a first end wall interconnecting the inner belt wall and the outer belt wall at the first end of the body, and a second end wall interconnecting the inner belt wall and the outer belt wall at the second end of the body. The inner belt wall, the outer belt wall, the first end wall, and the second end wall are integrally formed together as a single, unitary structure, such as by a casting process.

    Abstract: Presented are flutter countermeasure devices and control logic for active aerodynamic systems, methods for making/using such active aero systems, and vehicles equipped with spoiler flutter countermeasure devices for increasing downforce and decreasing drag. A method of operating an active aerodynamic system of a motor vehicle includes detecting, via a system controller based on sensor data received from one or more sensing devices, a flutter excitation experienced by a spoiler of the active aero system during operation of the motor vehicle. The controller determines a harmonic oscillation amplitude of the flutter excitation experienced by the spoiler, and then determines if this harmonic oscillation amplitude exceeds a vehicle-calibrated threshold amplitude. If so, the system controller determines a damping force sufficient to mitigate or eliminate the harmonic oscillation amplitude. The controller then commands a flutter countermeasure device operatively attached to the spoiler to generate the damping force and thereby mitigate the flutter excitation.
