Publication number: 20080191638Abstract: A ballast circuit is disclosed for inductively providing power to a load. The ballast circuit includes an oscillator, a driver, a switching circuit, a resonant tank circuit and a current sensing circuit. The current sensing circuit provides a current feedback signal to the oscillator that is representative of the current in the resonant tank circuit. The current feedback signal drives the frequency of the ballast circuit causing the ballast circuit to seek resonance. The ballast circuit preferably includes a current limit circuit that is inductively coupled to the resonant tank circuit. The current limit circuit disables the ballast circuit when the current in the ballast circuit exceeds a predetermined threshold or falls outside a predetermined range.Type: ApplicationFiled: February 25, 2008Publication date: August 14, 2008Applicant: ACCESS BUSINESS GROUP INTERNATIONAL LLCInventors: Roy W. Kuennen, David W. Baarman, Scott A. Mollema, Ronald C. Markham, Dennis J. Denen

Publication number: 20040140194Abstract: A method and apparatus for reducing air contamination using a contaminant adsorbent to remove contaminants from air, and a nonthermal plasma to desorb and oxidize or detoxify the contaminants. The adsorbent may be comprised of a unique combination of a zeolite with a material having a high dielectric value. The power supply for the nonthermal plasma reactor is designed to seek and operate at the system resonant frequency. In one embodiment, the adsorbent material is separated from the nonthermal plasma reactor. In this embodiment, heat is applied to the adsorbent material to thermally desorb contaminants during a desorption/regeneration phase. Air is recirculated within the system to move desorbed contaminants from the adsorbent material to the nonthermal plasma reactor for decomposition. The recirculating air repeatedly moves contaminants through the reactor until they are destroyed or the desorption/regeneration phase is complete.Type: ApplicationFiled: August 7, 2003Publication date: July 22, 2004Inventors: Roy M.

Publication number: 20030205518Abstract: A filter assembly designed for use in a water treatment system is provided. The assembly includes an inner carbon-based filter and an outer replaceable pleated filter. Untreated water flows first through the outer filter, which traps particulates, and then through the inner carbon-based filter, which traps particulates and adsorbs contaminants from the water. The outer filter is intended to be easily removed from the inner filter, so that the outer filter can be removed and cleaned or replaced when plugged with particulates. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 C.F.R. 1.72(b).Type: ApplicationFiled: May 6, 2002Publication date: November 6, 2003Inventors: Karen J.
