An internal combustion engine for a vehicle, such as a motorcycle, includes a crankcase, two banks of cylinders projecting from the crankcase in a 56-57 degree V-configuration, a plurality of pushrods, and a plurality of camshafts supported by the crankcase. In one embodiment, the reverse auction immediately ends if an offer below the reserve price is received. The elongate actuator arm includes a heater layer of a conductive material and a dielectric, resiliently flexible layer. Most preferably, the digital audio source is programmable with recorded sounds that can be transferred from a remote bank of digital sounds, for example by being downloaded from an internet website. The pixel shader and texture unit between them are configured to calculate texture space gradient values for one or more primitives and generate and apply per-pixel gradient scale factors configured to modify the gradient values to smoothly transition them between regions of a display device having different pixel resolutions. With this arrangement, it is possible to automatically change carriers and thereby continuously use a cleaned carrier in the subsequent step without using a dedicated carrier.
