Publication number: 20080098514Abstract: A drink beverage coaster is specifically meant to attach to a urinal flush valve top cap. It attaches itself by a vertical wall or a plurality of individual walls that extend 90 degrees away from the underside of the top coaster part that conform around the urinal flush valve top cap, and attached to the side edges of the top cap via an elastic spongy material attached on the inner sides of the vertical walls, that not only conforms to the shape of the urinal flush valve top cap, but when it is put over a top cap, the top cap pushes against the spongy material applying force against the spongy material that in turn applies force against the inner side of the downward vertical walls which then apply pressure back to the elastic spongy material which applies the pressure back to the top cap sides.Type: ApplicationFiled: December 26, 2007Publication date: May 1, 2008Inventor: Shawn Kelley

Patent number: 7355376Abstract: A method for determining a recovery voltage in a battery includes detecting a transient increased current draw event drawing current from the battery, the transient increased current draw event starting at a start time and ending at an end time; and in response to detecting the transient increased current draw event, waiting until time and/or voltage criteria are met to determine recovered battery voltage. An implantable pulse generator (PG) device for stimulating a human organ includes a battery, a power sink drawing current from the battery, wherein drawing increased current from the battery for transient periods causes battery voltage to decrease; and a status indicator detecting a transient increased current draw event and waiting a minimum time duration after the transient increased current draw event to measure battery voltage in order to determine a recovery voltage.Type: GrantFiled: March 3, 2005Date of Patent: April 8, 2008Assignee: Cardiac Pacemakers, Inc.Inventors: Rajesh Gandhi, John Dyjach, Shawn Kelley, Kristofer James, Paul McNamee

Patent number: 7239146Abstract: A manganese dioxide (MnO2) or silver vanadium oxide (SVO) or other battery of an implantable medical device having a relatively flat quiescent battery voltage during a beginning portion of the battery's useful life, makes it difficult to use quiescent battery voltage as an indicator of remaining battery energy during this portion of the battery life. A substantially constant load current pulse is drawn from the battery and a pair of loaded battery terminal voltage measurements is taken during this pulse. A difference between the voltage measurements is computed. This difference can be expressed as a rate of change, a slope, or a polarization angle, and can be used with stored data from similar batteries to determine remaining energy of the battery. A quiescent battery voltage can also be used in combination with this technique, and/or for distinguishing between different remaining energies corresponding to the same difference, slope, or polarization angle.Type: GrantFiled: July 11, 2003Date of Patent: July 3, 2007Assignee: Cardiac Pacemakers, Inc.Inventors: Kristofer J.

Publication number: 20060143822Abstract: This invention is simply a drink beverage coaster that is specifically meant to attach to the common urinal flush valve top cap. It attaches itself by little legs that come down from underneath the top coaster part that conform around the urinal flush valve top cap and hook to the underside lip of the top cap. When laying a bottle, can or glass on the chrome top cap or plumbing apparatus, a drink is prone to fall off on the floor because the surface is not large enough, flat enough and is too slippery to accommodate a beverage container. This invention snaps over the top cap allowing for easy removal for maintenance of the flush valve and may be put back on easily to accommodate those who have a beverage in hand at the urinal allowing for hands free operation of said bodily functions at the urinal without losing ones drink.Type: ApplicationFiled: January 3, 2005Publication date: July 6, 2006Inventor: Shawn Kelley
