Publication number: 20030091483Abstract: An automobile air filter comprising a filter element, an outer hood receiving the filter element, and a plurality of metal electrodes arranged in the filter element. Each pair of the metal electrodes is connected by a cable and pass through the outer hood. A high voltage generator circuit is installed at appropriate location of an automobile for generating instantaneous high voltage to provide instantaneous high voltage power to each pair of metal electrodes, so that the metal electrodes generate high voltage flashes and ozone to purify the air flowing in the filter element and increase oxygen content in the air intake in the engine.Type: ApplicationFiled: November 14, 2001Publication date: May 15, 2003Inventor: Lance Chao

Publication number: 20020038662Abstract: The invention provides a pair of parallel megasonic transducers that generate parallel columns of megasonic waves across a cleaning container. Semiconductor wafers move back and forth transverse to the columns. The transducers have their back side potted with a silicone elastomer to prevent corrosion. In another embodiment megasonic waves from in-line transducers are dispersed with a cylindrical quartz rod. Water is enriched with ozone by pumping ozone under pressure through a filter into sealed housing of deionized water.Type: ApplicationFiled: December 6, 2001Publication date: April 4, 2002Applicant: INTERSIL CORPORATIONInventors: Malcolm R. Schuler, Robert F. Longenberger, Rodney S. Ridley, Thomas E. Grebs, Jason R. Trost, Raymond J. Webb, Michael A. Caravaggio, Terry L. Fenstermacher

Patent number: 6312507Abstract: A hand-holdable electro-kinetic electro-static ionic air refreshener-conditioner for a pet shelter or litter box includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first array comprises one or more pin-like electrodes and the second array comprises one more washer-like electrodes. Preferably a ratio between effective area of an electrode in the second array compared to effective area of an electrode in the first array exceeds about 15:1 and preferably is about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. Optionally, a sensor detects odor adjacent the refreshener-conditioner causes the ion generator to be activated when sensed odor exceeds a predetermined threshold.Type: GrantFiled: February 12, 1999Date of Patent: November 6, 2001Assignee: Sharper Image CorporationInventors: Charles E.
