An inkjet printing system, comprising: one or more inkjet printheads for printing drops of ink onto a receiver medium, and an acoustic air impingement drying system positioned in proximity to at least one of the inkjet printheads. A package for packaging multiple fiber optical components can include a bottom portion comprising at least two cavities. The covered layer and underlying metal may be removed, for example, using acid. Next, the system divides the violating data vectors into a number of subsets, thereby allowing parallel SVM training for each subset.
