    Abstract: The embodiments of the present invention disclose an event detection method and device. The method includes: predefining event-based detection rules with a predicative context-free grammar; generating by parsing the detection rules a parsing table of pushdown automaton which supports parallel parsing; receiving an event to be detected; and analyzing by a controller the event to be detected according to the parsing table, to obtain a detection result. The present invention is especially applicable to detection of network attack events. The embodiments of the present invention detect the attacks with a predicative context-free grammar on the basis of events, and ensure a close combination of a protocol parsing process and an attack detection process, as well as a close combination of multiple attack detection rules, thus decreasing unnecessary calculations. In addition, with an optimized parallel pushdown automaton, the embodiments of the present invention can efficiently analyze the predicative context-free grammar. Consequently, besides hierarchical processing capability and state description capability, the embodiments of the present invention deliver high efficiency.

    Abstract: A magnetic write head and method of manufacture thereof that has a first pole structure having a step notched first pole structure. The step notched structure includes a bottom notched portion that is wider than the second notched portion formed thereover. The upper, or narrower, notched portion has a width that is substantially equal to and self aligned with a second pole structure (P2) formed thereover. The invention may also include first and second wing portions formed in the first pole that are recessed from the ABS and that extend laterally from the first notched portions of the first pole. The formation of the winged portions is assisted by an ion mill resistant bump (alumina bump) formed thereover, which acts as a mask during the ion milling operations that are used to form the first and second notches.
