Herein is described an implementation of an object persister, which serializes an object to preserve the object’s data structure and its current data. The systems, methods, and programs identify a partition file corresponding to a partition that is to be updated. The computers are filtered into at least one filter group and a list of computers in the filter group is displayed along with the status for each patch. The bidirectional communication section transmits the view-information packet input from the view-information generating section to a broadcasting apparatus through a bidirectional communication network. This procedure accounts for the presence of noise in the recognition phase by retraining all the templates using an estimated noise signal with similar characteristics as the actual noise signal that corrupted the word to be recognized.
