    摘要： A system and method for transmitting electrosurgical energy from a generator to an electrosurgical instrument are provided. The electrosurgical system includes a generator adapted to generate electrosurgical energy for treating tissue. The generator includes one or more active output terminals which supply energy to the tissue. The active output terminals are operatively connected to one or more active leads. The generator also includes one or more return output terminals which returns energy from the tissue. The return output terminals are operatively connected to at least one return lead. The system also includes an electrosurgical instrument operatively connected to the one or more active leads and one or more return electrodes operatively connected to one or more return leads. The system further includes an electrosurgical cable including one or more active leads and one or more return leads. The one or more active leads and one or more return leads are wound in a double helix fashion such that the electrical field along the cable is mitigated along the length thereof.

    摘要： A method for suppressing arc formation during an electrosurgical tissue treatment procedure includes the steps of supplying pulsed current from an energy source to tissue and measuring the pulsed current supplied from the energy source. The method also includes the steps of comparing an instantaneous measured pulse to a predetermined threshold and controlling the pulsed current supplied from the energy source based on the comparison between the instantaneous measured pulse and the predetermined threshold.

    摘要： The existence of autorotation of a load (e.g., a helicopter rotor system) coupled to the free turbine of a gas turbine engine is determined and a signal indicative thereof enables an integrator which, upon autorotation, integrates rate-based recovery anticipation provided thereto, the integrator output providing a time-composite bias signal to the main control portion of the engine fuel control to increase the speed of the gas generator of the engine in anticipation of rotor reengagement with the free turbine. The amount of recovery error is determined from the rotor speed error and is multiplied with the integrator output, the product being fed, upon completion of autorotation recovery, to the integrator input whose output now provides a controlled removal of the bias signal from the main control portion so as to minimize transients induced therein.
