A computer-implemented method and apparatus for processing a spoken request from a user to control an automobile device. From the top level image of the luminance pyramid a global motion vector is determined between images at times t and tn. The deformation element is engaged by the resistance facilitating element during further rotation of the belt roller in a manner to increase the resistance of the belt roller to further extraction of the belt. The flow path may include multiple vortex chambers, and the device may include multiple flow paths. In at least one embodiment, the positron emission tomography module includes a gamma ray detector arrangement designed such that it can alternately be combined with a magnetic resonance tomograph and with a computed tomograph.
