An electric machine has a stator and a rotor. The system includes a service center having a navigation server and associated workstations. A monolithic body of phase change material substantially encapsulates the conductors and holds said toroidal core in place. The signed permission object includes a sequence number and is associated with an expiration counter having an initial value that indicates a lifetime for the signed permission object. A deviation from the normal increments of displacement for each set triggers a \u201ctray full\u201d condition which alerts a user to empty the tray. Hence, the present invention takes the idea of capabilities and applies it to defining the capabilities or access privileges of different native executable code for secure, single-user mobile wireless devices.
