A toroidal-type continuously variable transmission includes three trunnions and power rollers in a single cavity. One pressure chamber impinges upon the vehicle brake in an applied position and the other pressure chamber impinges upon the vehicle brake in a release position. The watch strap can move in one direction in order to tighten the watch strap around the user’s wrist, but is prevented from moving in an opposite direction. As simply one example, if, based upon the hints, the controller for the IO cache knew that the data being fetched was ATM data, then it would also know that precisely a forty-eight byte data payload was to be sent to the requesting device, and the IO cache could pre-fetch precisely this amount of data. The BEMF is proportional to motor speed and independent of motor load.
