The present solution to the medical triage problem is computer automated telephone triage system that gives customized medical advice to patients of doctors who have registered with the service. An accumulator is disposed between the pump and the nozzle, wherein the accumulator is a high pressure accumulator storing energy between pulses of the pulsed water jet and the pressure drop at the accumulator inlet due to the release of each pulse of the pulsed water jet is less than twenty percent. The carbon nanotube film structure extends in a curve in the flexible polymer matrix. A masking layer may be used to define an input window. In one implementation, a pool of tokens is maintained based on the comparing. A second varistor is arranged parallel in relation to the switching path of the power transistor and in series with a switching transistor.
