    • A method of processing a workpiece in a plasma reactor includes coupling RF power from at least three RF power source of three respective frequencies to plasma in the reactor, setting ion energy distribution shape by selecting a ratio between the power levels of a first pair of the at least three RF power sources, and setting ion dissociation and ion density by selecting a ratio between the power levels of a second pair of the at least three RF power sources. The three respective frequencies can be an LF frequency, an HF frequency and a VHF frequency, wherein the first pair corresponds to the LF and HF frequencies and the second pair corresponds to the HF and VHF frequencies. Alternatively, the power sources comprise four RF power sources, and wherein the first pair corresponds to an HF frequency and an LF frequency and the second pair corresponds to a VHF frequency and another frequency. In one embodiment, the second pair corresponds to an upper VHF frequency and a lower VHF frequency. The other frequency may be coupled through an inductive source power applicator, a toroidal plasma source power applicator or a ceiling electrode. Or, all three frequencies may be coupled through a wafer support pedestal of the reactor.

    • A vehicle suspension spring system for a vehicle wheel station includes a hydraulic cylinder or strut having a piston which divides the cylinder volume into a main oil volume and an annular oil volume. The main oil volume communicates via a first oil passage with a first accumulator having a main gas volume. The annular oil volume communicates via a second oil passage with a second accumulator having an auxiliary gas volume. The oil in each accumulator is separated from the gas by a separator piston or diaphragm. A third oil passage with an isolating valve interconnects said first and second oil passages. Operation of the isolating valve is regulated by a controller. At least one sensor for sensing a parameter associated with vehicle attitude is connected to the controller. The controller is operable for switching the isolating valve between open and closed positions for altering spring stiffness of the strut in response to said sensed vehicle attitude parameter when the vehicle is in motion.
