A first acquisition unit acquires an event notification from an MFP and updates first device-status information. The fuser assembly includes a heat transfer member for generating heat and a backup roll coupled to the heat transfer member and rotatable therewith. Differences between time-stamp values are used as indicators of QoS service at each router. The mixing baffle may also include a second set of stationary mixing elements that interlace with the first set of moveable mixing elements when the first set of moveable mixing elements moves to the second configuration. To locate a query in the audio corpus, constituent subword units in the query are indentified and then locations of those subwords are determined based on the locations of those subword units determined earlier by the wordspotter, for example, using a pre-built inverted index that maps subword units to their locations. These compounds are useful as HDAC inhibitors.
