A personal transportation vehicle. The personal transportation vehicle provides an outer and inner shell having a rotor assembly supported between. The inner shell defines a compartment, which in turn houses an input system that controls an electromagnetic drive system. The electromagnetic drive system includes electromagnets that can generate a magnetic field. A sensor detects motion of the rotor assembly and stabilizes the inner shell. A controller controls states of each electromagnet depending on a position of the rotor assembly and an input from the input system. The electromagnets of the electromagnetic drive system cooperatively cause the personal transportation vehicle to move.

Various communication systems may benefit from appropriate restriction on use. For example, certain wireless communication systems may benefit from radio-access-technology-specific access restrictions. A method can include registering a user equipment with a network element. The registering can include identifying user equipment capabilities. The method can also include receiving a response from the network element indicating restriction on use of at least one radio access technology.

A gyroscopic module comprises at least one gyroscopic rotor rotatably mounted to a support, wherein the at least one gyroscopic rotor is driven by at least one first power source and at least one gimbal frame is coupled to the support of the at least one gyroscopic rotor. The gyroscopic module comprises at least one slew bearing coupled to the at least one gimbal frame to change an orientation of the at least one gyroscopic rotor, wherein the at least one slew bearing is driven by at least one second power source mounted to the at least one gimbal frame.
