Abstract: The present invention provides methods and apparatus for abstracting network processors using a virtual machine. The virtual machine approach substantially abstracts the network processor, letting the application developer focus all attention on packet processing. In accordance with the present invention, the NPU-based virtual machine provides the functionality of a pipelined engine, N-way parallelism, or both. The present invention provides a high-level functional language for expressing a wide variety of packet processing applications. The high-level functional language provides primitives in the form of instructions such as, but not limited to, tracking a connection or session, removing an outer header, translating an IP address, encrypting a packet, and scanning the payload for a regular expression.

Abstract: An automated bulk dispensing system and a method of use including selectively receiving a predetermined amount of radioactive liquid from a second container into a third container, selectively receiving a predetermined amount of nonradioactive liquid from a first container into a fourth container or directly into the third container depending on whether kits or multi-dose containers of medicine are desired. Preferably, this is for nuclear pharmaceuticals. Displacement mechanisms that are connected to the third container and fourth container are for mixing and dispensing liquid. There is at least one control valve, preferably three control valves, which are each controlled by drive mechanisms. The mixed liquid from the third container can be transferred to a recipient container. There is also a gas vent and bubble detector to eliminate bubbles with a processor that is also utilized to control the displacement mechanisms and the drive mechanisms.

Abstract: A vehicle seat suspension, of the type comprising a seat frame supported on a base frame by two spaced pairs of scissor action linkage arms, has the ends of the linkage arms connected to one of the frames wholly by pivotal connections having freedom for displacement longitudinally of the suspension and a resilient coupling connecting the one frame to one of the linkage arms to damp the transmission of vibrations between the frames in the longitudinal direction.
