Abstract: A compressor wheel for a turbocharger includes first, second and third pluralities of blades formed around a central hub. Each of the second plurality of blades is disposed between adjacent blades from the first plurality of blades and extend a shorter distance than the first plurality of blades along the centerline of the central hub. Each of the third plurality of blades is disposed between adjacent blades from the first and second pluralities of blades, and extends a shorter distance than the second plurality of blades along the centerline of the central hub. Together, the blades are separated in sets, each set including a blade from each of the first, second and third pluralities in order with respect to any radial location around the compressor wheel as the compressor wheel rotates.

Abstract: A compressor for a turbocharger for use with an internal combustion engine includes a compressor wheel having a central hub having a centerline, a root portion, and an end portion. A plurality of blades is formed around the central hub. The plurality of blades includes a group of full-blades extending from the root portion of the central hub up to a maximum distance from the root portion along the centerline, the maximum distance being adjacent the end portion of the central hub. The plurality of blades includes a group of half-blades, the half-blades extending from the root portion of the hub to an area along the centerline that is between 60% and 65% of the maximum distance along the centerline. The plurality of blades is organized in repeating sets of blades arranged around the compressor wheel, each repeating set including at least one full-blade and at least one half-blade.

Abstract: An automated temperature control system for a barbecue grill or other structure comprises an automated damper assembly coupled to a vent of said grill, which damper assembly opens and closes selectively to adjust the flow passage area of the grill's vent. The system further comprises an operating area temperature probe for communicating the temperature of the operating area of the grill to the automated damper assembly, such that the automated damper assembly may maintain a user-specified target operating temperature by way of affecting combustion rates within the grill. A remote control may also be provided to allow the user to input a desired temperature for the system to obtain and/or to change temperature information for the grill or other structure.
