摘要:
This invention relates to a method of sterilizing air that contains airborne pathogenic agents or microorganisms such as spores, bacteria, viruses, yeasts and moulds The method consists in damaging and braking up the contaminant molecular structure by oxidation and ionization and chemical bond rupture. Through this process the microorganisms or the contaminants are inactivated through structural damages to the cellular membrane and/or the nucleus membrane and/or to the DNA structure. This is accomplished by creating through the air to be treated, various electronic current having a plurality of specific controlled average kinetic energies matching the desired chemical bonds to be affected and/or ruptured. The air interaction with such various currents, having specific energies, sufficient intensities and exposition time is accomplished through several stages to completely sterilize the air or gas. The air or gas is then processed to remove undesirable by-products that may be present so that it can be used directly or stored.

A system for decontaminating a gas is provided. The system includes: a passageway containing at least one set of two or three electrodes. If the set contains three electrodes, it has two outer electrodes electrically connected together and one inner electrode. A high voltage waveform source for creating electrical fields between the electrodes, wherein the electrical fields interact with the gas to create an electronic current having a desired average energy level to at least match the energy level of the molecular bonds of the contaminants to be ruptured and wherein the set has either (a) at least one surface of the inner electrode and a corresponding exposed surface of the outer electrodes (in the case of a set with two electrodes, both exposed surfaces) are fitted with protuberances having a controlled geometry controlling an amplification factor of the electric field at extremities of the protuberances; or (b) a space between at least one outer electrode and the inner electrode (in the case of a set with two electrodes, a space between the electrodes) is at least partially filled with elements made for a dielectric material.
摘要:
The process for controlling an electronic power component for piloting an opening and/or closure of this component. The piloting process includes a plurality of steps for controlling the application of a succession of different commutation voltages on a control electrode of the electronic power component between an instant when the piloting process begins and an instant when either the opening or the closure of the electronic power component is to stop. Passage from one commutation voltage to a successive commutation voltage in this piloting process is automatically effected as soon as a corresponding condition of passage is satisfied. The process further includes a step of interrupting the piloting process and immediately triggering off a process for safeguarding the integrity of the electronic power component if the component does not react to a commutation voltage within a predetermined time for the commutation voltage.

A carrier frequency modulating system and method for producing a modulated carrier frequency is disclosed. The system comprises a carrier frequency signal generator for producing a carrier frequency signal at a carrier frequency at an output thereof. The system further comprises a sequencer for producing a modulation signal at an output thereof. This modulation signal comprises a plurality of modulation signal portions separated by at least one null modulation signal portion having a corresponding time length. The system is provided with a modulator for producing a modulated carrier frequency signal at an output thereof. The modulator has a first input connected to the output of the carrier frequency signal generator for receiving the carrier frequency signal, and has a second input for receiving the modulation signal. The system further comprises a power supply unit for supplying electrical power to the carrier frequency signal generator. The sequencer is connected to the carrier frequency signal generator for controlling the activation thereof and to interrupt the carrier frequency signal generator instead of modulating the null modulation signal portion during the corresponding time length, whereby power consumption of the system is minimized.
