The present invention is related generally to analysis of polynucleotides, particularly polynucleotides derived from genomic DNA. The gantry assembly is operable to move each of the plurality of containers between the interior storage area and the staging area. , preferably: dichloromethane, chloroform, toluene, xylenes, turbosine, naphtha or mixtures thereof. A scene feature information storage module generates scene feature information including the duration, key frame, importance level, and image feature amount of the key frame of the scene designated by the scene designation module, and stores the generated information in a memory in correspondence with the moving picture data. The invention also relates to a method for storing and releasing electrical energy using such an accumulator.
