摘要： A macro electrically active mask includes two conductive layers separated by at least one filtering and insulating layer. The conductive layers are connected to each other by a power source. The power source includes an oscillator and a high voltage transformer. The power source generates a periodic voltage with a fundamental frequency and multiple harmonic frequencies. The power source is connected between the two conductive layers and the periodic voltage generates a periodic electric field between the two conductive layers. The fundamental frequency, the duty cycle, and the amplitude of the periodic voltage are configured to inactivate the microorganism that pass through the electric field.

摘要： An exhaust treatment system includes a dust-removal system. The dust-removal system has an electric field device (1021) and an exhaust cooling device. The electric field device (1021) includes an inlet of the electric field device, an outlet of the electric field device, a dust-removal electric field cathode (10212), and a dust-removal electric field anode (10211), the dust-removal electric field cathode (10212) and the dust-removal electric field anode (10211) being used for generating an ionization dust-removal electric field. The exhaust cooling device is used for reducing an exhaust temperature before the inlet of the electric field device. An exhaust dust-removal system facilitates to reduce greenhouse gas emission, and also facilitates to reduce hazardous gas and pollutant emission, so that gas emission is more environment-friendly.

摘要： An engine emission treatment system incudes at least one out of an air inlet dust removal system (101), a tail gas dust removal system (102), and a tail gas ozone purification system. The tail gas dust removal system (102) has an inlet of the tail gas dust removal system, an outlet of the tail gas dust removal system, and a tail gas electric field device (1021). The tail gas ozone purification system has a reaction field (202), used for mixing an ozone stream and a tail gas stream for reaction. The engine emission treatment system may effectively treat engine emissions, so as to make the engine emissions cleaner.

摘要： A covering includes an outer material, a plurality of conductive-fibers, and a fastening material. The outer material includes a front surface and a back surface and the conductive-fibers are disposed between the front surface and the back surface. The conductive-fibers are configured to receive a voltage that causes the conductive-fibers to repel and remove dust from the front surface of the outer material. The fastening material is coupled to the back surface of the outer material and facilitates releasably attaching the outer material to an article.

摘要： The invention relates to a method and an apparatus for measuring particle concentrations in an aerosol. The apparatus comprises means (103) for driving flow (105) into apparatus (101), means (115) for electrically charging particles (109) to become electrically charged particles (123) by ions (113) produced by a charger, means (117) for removing free ions (113) which are not attached to the electrically charged particles (123), and means (119) for measuring electrical current carried by the electrically charged particles (123). The means (115) for charging the particles and the means (119) for measuring electrical current carried by the electrically charged particles (123) are dimensioned such that the means (119) for measuring electrical current carried by the electrically charged particles (123) only measures a part of a total current carried by the particles.
