A memory device having memory cells in which a single access transistor controls the grounding of at least two storage elements, such as resistive storage elements, for purposes of reading the respective logical states of the storage elements. The processing includes: obtaining a reference image including the background; comparing the at least one video frame to the reference image; and generating a pixel mask as a result of the comparison, the pixel mask indicating whether a pixel of the at least one video frame belongs to the foreground subject or to the background. 4:1; wherein the molar ratio of said catalyst to said highly esterified polyol polyester is in the range of from about 0. A temperature value along the temperature sensor curve is transformed into the corresponding burden resistance on the burden resistance curve. The parts list control section makes relation among the status data, the part number and the part data, and stores the status data in the parts list database.
