Patent number: 10014722Abstract: 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: GrantFiled: January 20, 2017Date of Patent: July 3, 2018Assignee: Philips IP Ventures B.V.Inventors: Roy W. Kuennen, David W. Baarman, Scott A. Mollema, Ronald C. Markham, Dennis J. Denen

Publication number: 20160340217Abstract: A portable water treatment system selectively configurable between a portable configuration and a water treatment system configuration. The portable water treatment system includes multiple nest and stack containers. A flocculation container includes a manual valve component that interacts with a filter support to form a valve that controls flow of water. The filter system may include one or more rotatable biofoam filters, each with a restriction orifice to control flow rate and allow a biological community to colonize and develop on or in the filters. The filters can be rotated between a filter operating position and a filter maintenance position. The water treatment system may include a chlorination system that can handle a chlorine tablet that does not contain a stabilizer. The water treatment system may include a storage container with a carbon filter that removes chlorine from the water before being dispensed.Type: ApplicationFiled: May 20, 2016Publication date: November 24, 2016Inventors: Roy W.

Publication number: 20120132575Abstract: A foam filter is provided that may form a radial flow or a stacked flow filter. In the radial flow configuration, the foam may be wrapped around an inner support core. The inner support core may define holes to allow the water to enter the support core and exit the filter. More than one foam layer may be used, and a single sheet of foam wrapped in a spiral may form a multi-layer configuration. A non-permeable flexible layer may be positioned between adjacent foam layers to facilitate flow through the filter. In the stacked flow configuration, multiple foam layers may be used and water can flow successively or simultaneously through the foam layers. Functional layers may be added to provide other filtration functions.Type: ApplicationFiled: November 29, 2011Publication date: May 31, 2012Applicant: Access Business Group International LLCInventors: Roy W.

Publication number: 20090045106Abstract: A water treatment system (“WTS”) includes a prefilter, a carbon block filter and a microbiological interception (“MI”) filter that operate in combination to treat a fluid stream, such as water. The WTS may include two prefilters, for example, both a multi-layer nonwoven prefilter and a pleated fabric prefilter. The MI filter may include carbon particles and a binder, and the carbon particles may have a mean particle diameter ranging from about 60 microns to about 80 microns and with a particle size distribution in which no more than about 10% by weight of the particles are larger than about 140 mesh and no more than about 10% by weight are smaller than about 500 mesh. In one embodiment, the water treatment system further includes a volumetric end-of-life filter monitor that monitors the life of the MI filter.Type: ApplicationFiled: August 15, 2008Publication date: February 19, 2009Applicant: ACCESS BUSINESS GROUP INTERNATIONAL LLCInventors: Roy W.
