Toner compositions comprising low-melt toner particles and methods of preparing such toner compositions are provided. Multiplexers in the system include data terminals, voice interfaces having voice trunks, high speed digital circuits and ISDN circuits, together with a control channel interface which connects trunking circuits by controlling calls on the control channel. If synchrony is detected the ventilator can return to EMG controlled ventilation. The second memory array couples to the second interface circuit. The air released via the pressure release valve is used for driving a compressor wheel of the compressor. When an activity in that predetermined subset of activities is detected a timing indication is added to the stream of trace elements.
