Abstract: A micro-channel cooling fin for a battery module and battery is provided. The cooling fin includes a metal plate assembly that defines a plurality of cooling channels therein. The metal plate assembly includes an inlet section for introducing a coolant into the plurality of cooling channels and an outlet section from which the coolant exits the plurality of cooling channels. Each channel has an output temperature and an input temperature such that the output temperature minus the input temperature for each cooling channel is within a predetermined amount.

Abstract: A turbocharger includes a compressor housing, turbine housing, and center housing between the compressor and turbine housings. A turbine wheel is disposed in the turbine housing on a turbine shaft. A compressor wheel having a shank is disposed in the compressor housing on the turbine shaft. The shank has outer and reduced portions. The reduced portion has a smaller diameter than the outer portion. A backplate is mounted to the compressor housing adjacent the compressor wheel and defines a stepped cylindrical bore with a maximum diameter portion and a minimum diameter portion having a smaller diameter than the maximum portion. The outer portion is disposed in the maximum portion. The reduced portion is disposed in the minimum portion. The outer diameter of the shank is greater than or equal to the minimum diameter of the backplate, and the stepped cylindrical bore and the shank define a variable width gap.

Abstract: A sensor lens assembly includes a cylindrical sensor body including a lower surface, a sensor lens surface, and a side surface extending between the lower surface and an outer edge of the sensor lens surface, a sensor enclosed within the cylindrical sensor body and adjacent to the sensor lens surface, and a nozzle configured to deliver a fluid near a center point of the sensor lens surface. The sensor lens surface is concave and rotates relative to the side surface of the cylindrical sensor body such that centrifugal force causes the fluid to form a film on the sensor lens surface that acts as a barrier, cushion, and particle collecting medium on the sensor lens surface.

Abstract: A vehicle, window of the vehicle and a heating system for a window. The window includes a first pane and a second pane. A conductive coating is disposed between the first pane and the second pane, the conductive coating extending through a primary vision zone of the window from a secondary bottom vision zone of the window to a secondary top vision zone of the window. A first electrical wire is connected to the conductive coating within the secondary bottom vision zone for flowing a current into the conductive coating to generate heat within the primary vision zone.
