Patent application numberDescriptionPublished
20100288056Contamination Control for Liquid Handling - A structure for holding sample-containing receptacles includes a cover with holes formed therein through which the receptacles can be accessed with a substance transfer mechanism, such as a robotic pipettor. When the transfer mechanism is inserted into and then withdrawn from a receptacle, a string of viscous material may be suspended from the mechanism. A viscous string removal element adjacent each opening engages the string of viscous material and dislodges the string from the mechanism when the mechanism moves in a prescribed path with respect to the removal element. A sample rack configured to hold receptacles and to be inserted into the structure below the cover includes a sample rack having receptacle-receiving pockets, each with a resilient element and a positioning feature for holding receptacles of varying sizes in a predetermined position within the receptacle receiving pocket, and a cover including features for preventing a receptacle from being pulled out of its receptacle-receiving pocket when the transfer mechanism is withdrawn from the receptacle.11-18-2010

20090145428System and Method for Controlling Supply of Oxygen Based on Breathing Rate - A portable oxygen concentrator system weighing 4-20 pounds that is adapted to be readily transported by a user and deliver oxygen to the user includes a rechargeable energy source; a concentrator powered by said energy source and adapted to convert ambient air into concentrated oxygen gas for the user; an inspiration sensor that senses respiratory activity of the user, and produces a signal in response thereto; and a control unit that receives the signal in response to sensed respiratory activity, determines a breath rate based in part on the received signal in response to sensed respiratory activity and controls the portable oxygen concentrator system to deliver oxygen flow sufficient to meet oxygen demand of the user based at least in part on the determined breath rate.06-11-2009

20080227892Paint formulations comprising cellulose ether/network building polymer fluid gel thickeners - Paint formulations that exhibit improved performance characteristics due to the presence of a combination of a cellulose ether (carboxymethylcellulose and/or hydroxyethylcellulose) and a network building polymer (gellan gum, carrageenan, etc., as examples) as a thickening system therein are provided. Such a combination permits long-term shelf stability of the paint formulation while simultaneously according effective flow, leveling, and other important properties to the final paint formulation. The combination of the cellulose ether and a network building polymer allows for a lower viscosity cellulosic compound to impart the desired rheological behavior therein while also permitting the other desirable characteristics noted above. Such paint compositions also exhibit improved atomization for spray applications with such a thickening system.09-18-2008
