A dolly for supporting a load vertically above a horizontal surface and moving the load upon the horizontal surface. In one embodiment, the constant voltage reset circuit comprises a reset capacitor, a parallel-coupled switch, and a diode coupled in series with the reset capacitor which is configured to cooperate therewith to reset an energy from the transformer. Software enables communication over the wide area network between a remote communications device, connected to the first interface, and a core network of the cellular wireless communications network.
