Abstract: This disclosure provides crankshaft damper and tone wheel assembly having a low noise characteristic. The crankshaft damper and tone wheel assembly can provides both damping of vibrations excited in a crankshaft of an internal combustion engine and an indication of the rotational speed or position of the crankshaft. The crankshaft damper including a hub portion and a ring-shaped portion connected to the hub portion by plural spokes, and the ring-shaped portion has an inner circumference that surrounds an area including the hub portion and the plural spokes. The tone wheel includes an annular-shaped portion connected to the crankshaft damper and having an inner diameter, an outer diameter, plural teeth arranged at an equal pitch along the outer diameter, and a same rotational axis as the crankshaft damper.

Abstract: A non-linear fin heat sink is provided for dissipating/removing heat uniformly from a device, where the heat generation is non-uniform over that device, while also providing a small and relatively lightweight heat sink. The heat sink has extended surface protrusions that are optimally shaped in recognition of convective heat transfer, conductive heat transfer, and flow resistance allowing the heat sink to offset the temperature rise of a coolant media and provide enhanced cooling for the coolant temperature, deliver optimized cooling efficiency per the local physical properties of the coolant media, be used with a fluid for effectuating heat transfer; either liquid coolant, gas coolant or a combination thereof. Furthermore the heat sink features turbulence enhancement of the coolant stream by a pin array through which coolant stream passes, such fin array featuring a non-linear shape, spacing, and height pattern to provide optimal cooling while simultaneously reducing volume and flow resistance.
