  • Fluid vortex manifold
    Publication number: 20060001260
    Abstract: A fluid vortex manifold is for use in connection with a fluid drain plumbing system having a plurality of fluid sources and a fluid receptacle. A hollow circular cylindrical shell includes a periphery, a shell central axis, and a chamber adapted to receive the fluid material. A plurality of peripheral inlets, each having a diameter less than the shell diameter, is disposed around the shell periphery. The peripheral inlets are generally tangential to, and communicate with the shell chamber. The peripheral inlets are adapted to receive fluid material and direct it tangentially into the shell chamber, forming a vortex and suction, so as to preclude a backflow of the fluid material through the peripheral inlets. Each peripheral inlet has an inlet central axis. The shell central axis and the inlet central axis define skew lines. A single outlet is adapted to discharge all of the fluid material from the chamber.

  • Variable encryption scheme for data transfer between medical devices and related data management systems
    Publication number: 20050261934
    Abstract: The present invention provides for an encryption apparatus, system, and method in which data from an Implantable Medical Device (IMD) and a data center could be transferred based on a differentiated encryption system. The encryption scheme allows for the differentiation, segregation, and classification of data at required or needed levels of security. Before transfer of the data, either from an IMD or any other part of a support network for the IMDs, the encryption device begins to distinguish the data. The variable data is then classified based on various levels of security having distinct encryption protocols. After classification the data is encrypted based on the data's level of security. The data is then transmitted. Upon being received the data is then segregated based on whether the data is encrypted. The encrypted data is then de-encrypted and interpreted.

  • Electrical over stress robustness
    Publication number: 20050225912
    Abstract: Protection is provided against electrical surges resulting from Electrical Over Stress conditions, e.g., when interfacing circuits with powered connections. An EOS shunt is activated for as long as the EOS condition exists.

  • Encoding a TCP offload engine within FCP
    Publication number: 20050190787
    Abstract: The present invention defines a new protocol for communicating with an offload engine that provides Transmission Control Protocol (“TCP”) termination over a Fibre Channel (“FC”) fabric. The offload engine terminates all protocols up to and including TCP and performs the processing associated with those layers. The offload protocol guarantees delivery and is encapsulated within FCP-formatted frames. Thus, the TCP streams are reliably passed to the host. Additionally, using this scheme, the offload engine can provide parsing of the TCP stream to further assist the host. The present invention also provides network devices (and components thereof) that are configured to perform the foregoing methods. The invention further defines how network attached storage (“NAS”) protocol data units (“PDUs”) are parsed and delivered.

  • Method and system for operating a generator using a dynamic capability curve
    Patent number: 6924628
    Abstract: Method and system are provided for operating a generator using a dynamic capability curve. In one embodiment, the method allows providing a family of static capability curves corresponding to nominal reference levels of pressure of a fluid for cooling the generator. The method further allows acquiring data indicative of the actual pressure of the cooling fluid. A dynamic capability curve is generated to be responsive to the actual pressure of the cooling fluid. The family of static capability curves may be displayed relative to the dynamic capability curve, thereby allowing the operator to monitor and control the operation of the generator based on the actual pressure of the cooling fluid and further in view of at least one of the nominal reference levels of pressure for the cooling fluid.
