A low cost, highly reliable linear oscillatory actuator comprising a yoke formed of magnetic material; an excitation coil wound on the yoke; and two permanent ring magnets arranged around the yoke and integrably set face-to-face on a common magnetic pole along the axial direction. More data is put in packet payloads when more congestion exits in the packet network. The system and method also provides for authenticating the remote user with the control platform. When the hub rotates, the various lengths of electroluminescent light rotate about the hub in a circular pathway. The second transistor has a source region coupled to a reference low voltage, a drain region coupled to the gate of the driving transistor, and a gate coupled to a second scan line.
