A wireless communication system including a portable device and a vehicle device configured to transmit information including a vehicle state. At least one layer in the coating film is a hard film of a cubic metal compound including at least one element selected from the group consisting of the group 4 elements, group 5 elements and group 6 elements of the periodic table, Al, Si, B, Y and Mn together with at least one element selected from the group consisting of C, N and O. In certain embodiments, the resulting accuracy and CPU time reduction are a result of a Green’s function approach with the correct quasi-static limit, a modified discrete complex image approximation to the Green’s function, and a continuous dipole expansion to evaluate the magnetic vector potential at the distances relevant to VLSI interconnects and intentional inductors. When all transition probabilities exceed the threshold value at a stage of the trellis, the transition probabilities are scaled, such as by subtracting the threshold value. The heat transfer plate having independently controllable gas volumes which may be pressurized to locally control thermal conductance between a heater member and a cooling member such that uniform temperatures may be established on a plasma exposed surface of the showerhead electrode assembly.
