An apparatus for protecting a sensor device includes a cover mounted on the sensor device, the cover including a cover portion made from a transparent material that is transparent to sensor signals, the cover portion including an external surface having a wettability that varies according to a wettability gradient in a selected direction along the surface.

Variable wettability sensor device cover

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.

Electronic device to detect contamination, melt ice and remove water

A vehicle having a Lidar system includes a cleaning apparatus that performs a method of cleaning the Lidar system. The cleaning apparatus includes a nozzle for spraying a gas onto a window of the Lidar, a pump for controlling a flow of the gas through the nozzle, and a processor. The processor is configured to control the pump to control the flow of the gas through the nozzle at a variable flow rate.

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.

A fluid bearing for operably connecting a shaft to a center housing of a turbocharger is provided. The fluid bearing includes a single-piece bearing sleeve defining a bore between first and second ends that each form a thrust face. The sleeve includes first and second bearing portions proximal to an associated one of the first and second ends, and a shank connecting the first and second bearing portions. Each of the first and second bearing portions includes an outer bearing surface defining a maximum outer diameter, and each of the first and second bearing portions includes an inner bearing surface defining a minimum inner diameter for radially supporting the shaft in the bore. The inner bearing surface is a continuous surface free of grooves. The sleeve has a wall thickness defining oil passages spaced from the inner bearing surface and configured to supply oil to the thrust face.

A connecting rod for a device includes a rod having a large end, and a cap attached to the large end. The large end of the rod and the cap cooperate to define a first side surface and a second side surface disposed opposite to each other. The large end of the rod and the cap further define a crankshaft bore that extends along a crank axis between the first side surface and the second side surface. A thrust surface is defined by at least one of the first side surface or the second side surface, and is disposed on a thrust plane. The thrust surface includes at least one recessed region that extends inward away from the thrust plane of the thrust surface. Each of the thrust surfaces include ramps that extend between the recessed regions and the flat regions at the thrust plane of the thrust surface.

Connecting rod

An intake air flow control assembly includes an actuator, a valve shaft, a first valve member and a drive member. The actuator includes a drive shaft defining a first rotational axis. The valve shaft defines a second rotational axis. The first valve member is fixed for rotation with the valve shaft and adjusts air flow from an intake manifold to an engine intake port. The drive member is engaged with the drive shaft and the valve shaft. The drive member extends around an outer circumference of the drive shaft and around an outer circumference of the valve shaft. The drive shaft is rotatable in first and second rotational directions opposite one another to rotate the valve shaft via the drive member and rotationally displace the first valve member.
