20100197013METHOD FOR CULTURING STEM CELLS - A three-dimensional microwell system that supports long term pluripotent cell culture and formation of homogeneous embryoid bodies (EBs) is described. Microwell-cultured pluripotent cells remain viable and undifferentiated for several weeks in culture and maintain undifferentiated replication when passaged to Matrigel®-coated, tissue culture-treated polystyrene dishes. Microwell-cultured pluripotent cells maintain pluripotency, differentiating to each of the three embryonic germ layers. Pluripotent cell aggregates released from microwells can be passaged for undifferentiated replication or differentiated to monodisperse EBs. The ability to constrain pluripotent cell growth in three dimensions advantageously provides for more efficient, reproducible culture of undifferentiated cells, high-throughput screening, and the ability to direct pluripotent cell differentiation by generating monodisperse EBs of a desired size and shape. Cardiomyocyte-rich EBs are obtained from pluripotent cells cultured in microwells of defined size and shape.08-05-2010

20090139493Synchronizing common rail pumping events with engine operation - Noise and vibrations associated with a common rail fuel system drive linkage are reduced by synchronizing a high pressure common rail supply pump with engine operation. This may be accomplished by selecting a linkage associated with a desired ratio of engine speed to pump speed along with selecting a number of pump plungers and cam lobes that results in synchronizing action of the pump with engine combustion events. In particular, a pattern of pumping events per engine cycle repeats during each engine cycle. In a more sophisticated version, the pattern of pumping events per engine cycle includes a sub-pattern of pumping events that repeats an integer number of times each engine cycle, where the integer number equals the number of engine cylinders.06-04-2009
