Disclosed is an electrophotographic toner, including toner particles which contain at least a binder resin and a coloring agent and have been prepared in an aqueous medium, wherein the surfaces of the toner particles are treated with an Si compound in an amount of from 0. The system comprises a user equipment operable to request a bearer for communicating internet protocol data according to the second internet protocol to and from a gateway support node of the packet radio network. The processor system also comprises a wait for interrupt expansion circuit responsive to the at least one wait for interrupt output to provide an interrupt signal, at least one of said processor cores operable in response to the interrupt signal to schedule a maintenance function separated in time from execution of the application. The feed stripline includes an input coupled to a coaxial feed cable, and a pair of outputs, orthogonal in position and phase, coupled to each of the radiators. An electrical stimulus circuit in communication with the conductive terminals is used to generate and apply selected waveforms to induce a change in resistance of the device between relatively high and low resistance values.
