Publication number: 20100259220Abstract: An energy storage system includes battery cells and a controller. The battery cells include first and second cells. The controller controls a current to the first and second cells, such that a first charging method is utilized when a voltage potential of the first and second cells is less than a first voltage potential threshold, and a second charging method is utilized when the voltage potential of the first and second cells is equal to or greater than the first voltage potential threshold. The first charging method charges at least one of first and second cells at a greater rate than second charging method, and first charging method is utilized to charge first cell prior to being utilized to charge said second cell when said voltage potential of first cell is below the first voltage potential threshold and greater than the voltage potential of the second cell.Type: ApplicationFiled: June 23, 2010Publication date: October 14, 2010Applicant: EVEREADY BATTERY COMPANY, INC.Inventors: John D. Crawford, Peter F. Hoffman, David A. Spartano

Publication number: 20090323344Abstract: A light device is provided that includes a light source and electrical circuitry for supplying electrical power to the light source. The light device also includes a housing having first and second ends and a hollow interior defining a compartment for holding a power source. The housing comprises a woven fiber thermoset composite. The housing is made by applying woven fibers to a mandrel and impregnating the woven fibers with an epoxy and curing the epoxy impregnated woven fibers to form the thermoset composite housing. An electrical interconnect is provided within the housing having first and second resilient contacts for providing an electrical connection between the power source and the light source.Type: ApplicationFiled: June 26, 2008Publication date: December 31, 2009Inventors: John D. Crawford, Thomas D. Boris

Publication number: 20090225568Abstract: A light device includes a body having a light source and electrical contacts that plug into a first electrical outlet of a duplex receptacle and receive power therefrom. An outlet cover mounted for pivotal motion with respect to the body about at a pivot axis, which is substantially proximate to a region between the first outlet and a second outlet of the receptacle. The outlet cover pivots away from the body and towards the duplex receptacle to inhibit access to the second electrical outlet.Type: ApplicationFiled: May 19, 2009Publication date: September 10, 2009Applicant: EVEREADY BATTERY COMPANY, INC.Inventors: David Spartano, Kurt Matthew Richars, John D. Crawford, Scott W. Osiecki, Mark A. Ferguson
