A device to place an incision into matter with a harmonious plasma cloud. A radiofrequency generator system produces pulsed or continuous electromagnetic waveform which is transmitted by an active transmitter incising electrode tip. This generated electromagnetic wave is utilized to initiate a plasma cloud with processes such as thermal ionization and a photoelectric effect which then trigger an Avalanche Effect for charged atomic particles at the surface of the active transmitter incising electrode tip. This electromagnetic wave is impedance matched, frequency matched, power matched and tuned to the plasma cloud in order to sustain and control a harmonious plasma cloud with reduced atomic particle turbulence and chaos. This harmonious plasma cloud forms a coating over the surface of the active transmitter electrode tip as well as acts to reduce the energy needed from the power amplifier of our plasma cutting device. The electromagnetic wave is also used to produce a Pinch Effect to compress, contour, shape and control the harmonious plasma cloud. The electromagnetic wave is furthermore used to trap and contain the plasma cloud without the need of a solid matter containment vessel according to the Magnetic Bottle Effect of physics and a generated centripetal electric field force that acts to pull plasma particles inward toward the activated incising electrode tip. The Tunnelling Effect of physical chemistry is utilized to focus and amplify the energy delivered to the harmonious plasma cloud while shielding matter surrounding the intended path of incision from potential electromagnetic radiation exposure. The invention is an efficient, effective, safe, clean and inexpensive device which can be used to place an incision in matter.

A system and method for controlling knock in a lean burn internal combustion (IC) engine includes a spark plug having an electrode, and an electrical circuit configured to provide a first voltage to the electrode and detect an ion current during a thermal-ionization phase of the combustion process, and provide a second voltage to the electrode to create a spark and initiate a combustion process within a combustion chamber. The engine includes a controller configured to monitor the ion current for a knock condition that includes at least an incipient knock condition, determine a spark crank angle timing of the IC engine where the incipient knock occurs, and adjust the spark timing of the IC engine to operate at a crank angle that does not exceed a threshold level beyond an incipient knock set point.

A system for measuring in-cylinder parameters utilizing an image charge measured in an engine cylinder by an in-cylinder pressure sensor due to chemi and or thermal ionization in Engine. The in-cylinder pressure sensor includes a sensing element, which is a metal sensor probe with a selective coating (e.g., metal, oxides of metal, native oxides, semiconductor, oxides of semiconductors, ceramics, glass, dielectric, etc., in the form of a coating on the metallic probe, tube, etc) in order to function in harsh, corrosive and / or elevated temperature environments. The output of the sensor can be connected to a signal-conditioning unit, which includes a low noise differential charge amplifier with an auto offset correction circuit to measure fast varying signals. The signal out from the conditioning unit can be acquired utilizing a high-speed microcontroller-based data acquisition system with suitable software to analyze and estimate parameters such as, for example, in cylinder pressure and knocking.

The invention aims at providing a method for online-analyzing organic monomer chlorine or bromine isotope, which adopts a direct negative chemical ionization to replace an original complex organic monomer conversion process. The method is characterized by including the steps: A. gathering chlorine or bromine substitute; B. separating gas chromatography: placing the gathered chlorine or bromine substitute into the gas chromatography to be separated; C. conducting negative chemical ionization: components analyzed through chromatography directly flow into a negative chemical ion source through a capillary column, the negative chemical ion source replaces an original electron bombardment source configured on an isotope ratio mass spectrum to conduct the negative chemical ionization; D. mass spectrometric detecting: on a gas isotope ratio mass spectrum, selecting a faraday receiving cup corresponding to mass number of chlorine or bromine substitute directly, and receiving electronegative isotope fragment ions generated by the negative chemical ionization. The process is conducted under high vacuum state, and degree of vacuum is higher than 1.0*10<-3> Pa. The method greatly simplifies a process of online-analyzing organic monomer chlorine or bromine isotope and can form various special devices for detecting organic monomer isotope ratio.
