Abstract: A splitter system for a vehicle includes a splitter body having a first splitter body. The vehicle includes a vehicle body arranged along a longitudinal body axis and having a first vehicle body end configured to face oncoming ambient airflow. The splitter body is moveably mounted at the first vehicle body end and generates an aerodynamic downforce on the first vehicle body end when the vehicle is in motion. The splitter system also includes a mechanism configured to selectively translate the splitter body along the longitudinal body axis away from the first vehicle body end into the incident airflow and toward the first vehicle body end out of the incident airflow. The translation of the splitter body by the mechanism in turn adjusts the aerodynamic downforce generated by the splitter body on the first vehicle body end.

Abstract: A mixer includes a plurality of blades extending along a longitudinal axis. The blades are arranged in a single row, and are axially spaced from each other along a transverse axis. Each of the blades defines a window. Each of the blades includes an upstream portion, and a downstream portion. Each of the blades includes a bend at the window that forms an interior blade angle between its respective upstream portion and its respective downstream portion. The single row of the blades is arranged to include a first group of blades and a second group of blades. The interior blade angle of each of the blades in the first group faces in a first axial direction along the transverse axis. The interior blade angle of each of the blades in the second group faces in a second axial direction along the transverse axis.
Abstract: A method of controlling a vehicle includes moving a lift generating device to generate lift when a vehicle speed is greater than a pre-defined speed, a steering angle of the vehicle is equal to or less than a minimum angle value, a lateral acceleration of the vehicle is equal to or less than a minimum lateral acceleration value, and a corner brake fluid pressure at any of the wheels is equal to or less than a minimum brake fluid pressure. A downforce generating device is moved to generate downforce when the vehicle speed is greater than the pre-defined speed, the steering angle is equal to or greater than a maximum angle value, the lateral acceleration is equal to or greater than a maximum lateral acceleration value, and the corner brake fluid pressure at any of the wheels is equal to or greater than a maximum brake fluid pressure.
Abstract: An assembly for use in a designated listening area includes a body having a frame rail supporting or framing the body laterally adjacent to the designated listening area, and defining a cavity, and a subwoofer assembly having subwoofer speakers each defining a smaller second air volume. The subwoofer assembly is mounted to the frame rail such that the second air volumes are contiguous with and open into the first air volume. A sealing mechanism enclosed the first air volume within the cavity. A method includes providing a subwoofer assembly having subwoofer speakers defining respective second air volumes, mounting the subwoofer assembly to a frame rail laterally adjacent to the designated listening area such that the respective second air volumes are contiguous with and open into the first air volume, and sealing the first air volume with a sealing mechanism.
Abstract: An inertia locking mechanism for a bin having a bin lid and subjectable to an applied force resulting in an acceleration includes a housing attachable to the bin, a bracket attachable to the bin lid and having a locking feature, a locking pin, a biasing member, and a trigger. The locking pin is linearly moveable in the housing. The trigger has a triggering mass and is connected to the housing via a trigger pivot. The triggering mass is offset from the trigger pivot such that the triggering mass applies a torque to the trigger when the acceleration occurs in each of the front, rear, left, and right directions. The trigger is configured to release the locking pin when the acceleration exceeds a threshold acceleration such that the biasing member urges the locking pin into the locking feature of the bracket to lock the bin lid in a closed position.

Abstract: A system according to the principles of the present disclosure includes an engine cranking module and a throttle control module. The engine cranking module determines whether an engine is cranking based on at least one of an input received from an ignition system and engine speed, and generates a signal indicating whether the engine is cranking. The throttle control module selectively adjusts a throttle of the engine to a fully closed position when the signal indicates that the engine is cranking.
Abstract: Methods of repairing defects in polymeric composite structures are provided. The methods include filling or bonding defects with a pre-polymerization solution and polymerizing the pre-polymerization solution in situ. Patches or support structures can be disposed at the site of the defect to increase the strength of the repair or to make the repair cosmetically pleasing, respectively. Such a method of repairing a defect may include applying a pre-polymer solution having a reinforcing material and a monomer to the defect in a polymeric composite structure; disposing a support structure on a surface of the polymeric composite structure over at least a portion of the defect having the applied pre-polymer solution; and polymerizing the monomer in the pre-polymer solution to form a repaired region in the polymeric composite structure including a polymer having the reinforcing material distributed therein.

The ring gear is connectable to a non-rotating housing. The carrier member is operatively connected with the differential carrier.
Abstract: A method of testing a pressurized liquid fluid for dissolved gasses includes evacuating both a first tank and a second tank. A test volume of a pressurized liquid fluid is introduced into the first tank. An initial absolute pressure in the second tank is sensed, and then fluid communication between the first tank and the second tank is opened to allow the pressurized fluid to flow from the first tank into the second tank, thereby de-pressurizing the fluid. The de-pressurized fluid in the second tank is maintained for a pre-defined out-gassing period, to allow any gasses in the de-pressurized fluid to separate from the de-pressurized fluid. A final absolute pressure in the second tank is sensed. A difference between the final absolute pressure and the initial absolute pressure is correlated to a volume of gasses released from the de-pressurized fluid.
Abstract: A method of controlling a vehicle includes sensing movement of an interior door handle of the vehicle with a sensing device, such as a door lock switch. A position of a door of the vehicle is sensed with a door position sensor, after movement of the interior door handle is sensed, to determine if the door remains in an unopened position after movement of the interior door handle is sensed, or if the door moves into an opened position after movement of the interior door handle is sensed. When movement of the interior door handle is sensed and the door remains in the unopened position after movement of the interior door handle, instructions are provided with an audio or video device related to the proper procedure for unlocking and opening the door.
