A removable processor enclosure apparatus for use in a gaming machine having a housing defining an interior portion, and a first electrical connector disposed in the interior portion. The control unit is constructed such that, with the start of the operation of the synchronous machine, the stator winding of the synchronous machine is energized such that the rotor aligns itself corresponding to a magnetic preference direction parallel to the direction of the magnetic stator field generated by the energizing. At least the region of the mask shell or conduit surrounding or adjacent the vent assembly is formed from a relatively flexible elastomeric material. These models may be, for example, psycho-physical models. The containers comprise a thermoplastic polyester layer and an ethylene-vinyl alcohol copolymer layer, with the layer a being kept in direct contact with the both surfaces of the layer b, wherein the ethylene-vinyl alcohol copolymer satisfies the following formulae and and its differential scanning calorimetry gives a single peak for crystal fusion:. In various embodiments, the improved scanning tool uses at least one input capable of providing an indication of a desired operating mode of use; and an electronic control system configured to sense the desired operating mode indication, then select one of a plurality of operating system modes based on the desired operating mode indication.
