  • Patent number: 7623468
    Abstract: The present invention provides a packet processing device and method. A parsing processor provides instruction-driven content inspection of network packets at 10-Gbps and above with a parsing engine that executes parsing instructions. A flow state unit maintains statefulness of packet flows to allow content inspection across several related network packets. A state-graph unit traces state-graph nodes to keyword indications and/or parsing instructions. The parsing instructions can be derived from a high-level application to emulate user-friendly parsing logic. The parsing processor sends parsed packets to a network processor unit for further processing.

  • Patent number: 5727751
    Abstract: In the central rotating shaft of a rack for a tissue scroll an inner sleeve passes through a cover ring, and a spring is placed at an opening end of the inner sleeve; then the opening end of the inner sleeve and the spring are received in an opening end of a outer sleeve, and finally, the cover ring is engaged with the opening end of the outer sleeve such that the inner sleeve can be retractable between the outer sleeve and the cover ring by the force of the spring.

  • Patent number: 4615461
    Abstract: The present invention relates to an improved structure for an accessory container and in particular to one comprising an inverted U-shaped top cover having pimples mounted at the inner edge of the cover. The pimples may slide within the grooves of the container. The extreme end of each groove has an oval-shaped slot. The top cover can slide within the grooves of the container in which the grooves are positioned on the lateral sides of the container. With the slots and pimples defining a hinge, the top cover can be overturned angularly for 180 degrees and lay just directly below the container. The top cover has the advantage of preventing dust from contacting the accessory and at the same time, it can be disposed under the container. Hence, this assembly does not occupy much space. By providing an arrangement including dimples, pimples and grooves, the pimples of the top cover may slide within the grooves if the top cover is pushed in a planar direction by means of a pushing grip.
