Abstract: Laminated glass speaker systems include at least one pair of asymmetrical piezoelectric exciters within a laminating material used to effectively bond glass panels together. The laminated glass speaker system can be utilized about the vehicle anywhere sound generation is desired, e.g., passenger windows, fixed or sliding roofing systems, front windshield, rear windshield, side windows, rear quarter glasses, and the like. The piezoelectric exciters are generally off-axis relative to a centerline longitudinally extending between the glass panels and act as a diaphragm to produce sound upon vibration.

Abstract: A Lidar system, window of the Lidar system and a method of moving a fluid along a window. The window includes a first electrode disposed on a first side of a outermost layer of the window, a second electrode disposed on the first side of the outermost layer, and a processor. The processor is configured to activate the first electrode to draw a fluid to a first location on a second side of the outermost layer opposite the first electrode, deactivate the first electrode, and activate the second electrode to draw the fluid to a second location on the second side of the outermost layer opposite the second electrode.

Abstract: A turbocharger assembly includes a center housing which defines a bore, a journal bearing, and a rotating assembly. The bore further defines primary and secondary annular grooves. The journal bearing may be disposed within the bore such that the annular groove encircles the journal bearing and feeds the fluid thereto. The rotating assembly includes a shaft, a turbine wheel and a compressor wheel. The turbine wheel is configured to be driven by the post-combustion gasses while the compressor wheel pressurizes the airflow for delivery to a combustion chamber. The shaft may be supported by one or more journal bearings for rotation within the bore about a longitudinal axis. The shaft includes a shaft surface which defines a standard region and a feature in a feature region. The feature is configured to generate a plurality of fictitious forces which stabilizes the turbocharger shaft.

Abstract: Laminated vehicle glass structures included embedded piezoelectric exciters for sound generation. The piezoelectric exciters are embedded at least partially within the laminating materials and are offset relative to a centerline longitudinally extending between the opposing glass panels. Also disclosed are processes for forming the laminated glass structures. The laminated glass structures can be utilized about the vehicle anywhere sound generation is desired, e.g., passenger windows, fixed or sliding roofing systems, front windshield, rear windshield, side windows, rear quarter glasses, and the like. The piezoelectric exciters act as a diaphragm to produce sound upon vibration.

Abstract: A sensor assembly includes a sensor and a cover disposed adjacent to the sensor to protect the sensor. The cover has an inner cover surface and an outer cover surface opposite the inner cover surface. The inner cover surface faces the sensor, and the outer cover surface faces away from the sensor. The cover has a first end wall and a second end wall apart from the first end wall along a first direction. The sensor assembly includes a cleaning system having a wiper movable along the outer cover surface of the cover in the first direction to clean to the outer cover surface. The wiper is at least partly made of a wiper material, and the wiper material includes a hydrophilic material to facilitate removal of water from the outer cover surface of the cover.

Abstract: Disclosed are journal bearing assemblies, methods for making and methods for using journal bearing assemblies, and motor vehicles employing journal bearing assemblies. A disclosed friction-reducing journal bearing assembly includes a first (upper) bearing shell insert and a second (lower) bearing shell insert. Each insert mounts inside a bore, e.g., of an engine block or piston connecting rod, and has an arcuate inner-diameter (ID) surface. These ID surfaces are adjoined at opposing ends thereof to cooperatively define a cylindrical channel that receives therethrough a journal portion of a shaft (e.g., crankshaft or crank pin). The inner-diameter and/or outer-diameter (OD) surface of the second insert includes one or more axially elongated and/or one or more axially angled grooves, each of which extends only partially across the axial width of the shell insert. The lower insert may be fabricated with two axially elongated grooves extending generally orthogonally from respective edges of the insert.

Abstract: Laminated vehicle glass structures included printed piezoelectric actuators for sound generation. Ring-shaped piezoelectric actuators are printed on an inner surface of a selected one of the exterior glass panel or interior glass panel. The printed piezoelectric actuators are offset relative to a centerline longitudinally extending between the opposing glass panels. Also disclosed are processes for forming the laminated glass structures including at least one printed piezoelectric actuator. The laminated glass structures can be utilized about the vehicle anywhere sound generation is desired, e.g., passenger windows, sunroofs, front windshield, rear windshield, and the like. The printed ring-shaped piezoelectric actuators act as a diaphragm to produce sound upon excitation.
