Abstract: A method and system for bootstrapping a processor from a volatile memory device connected to the processor is disclosed. The first processor is bootstrapped from flash device. The reset lines of the second processor are asserted. The boot code for the second processor is loaded from the flash device into the volatile memory device. The reset lines of the second processor are de-asserted, wherein the processor then boots from the boot code stored in the volatile memory device. The same boot-strapping method can be extended to multi-drop systems where number of secondary processor can be more than one. A switchable means for the second processor to boot from volatile memory as described or from flash memory. A method also describes a mechanism to boot from synchronous volatile memory devices.

Abstract: A storage router and related method are presented for combining multiple host frames, such as Fibre Channel frames, together into a single datagram for tunneling transmission over an IP or similar network. The storage router operates by storing incoming host frames in a host frame buffer. When there is sufficient data in the buffer, multiple host frames are batched together, compressed, and converted into an IP datagram. The number of host frames to be batched together can be established through a variety of tests, including total bytes of data, number of frames, or through a time-out mechanism. The network layer then fragments the datagram into data link level frames, such as 1500 byte Ethernet frames. When the datagram arrives at the final destination, the segmented datagram is reconstructed, decompressed, and the multiple host frames are then extracted and passed on to the recipient host frame network.

Abstract: Data cells are described containing an entity identifier (“O”), an entity type (“E”) an attribute type (“A”), and an attribute value (“V”). Cells with identical O and E values constitute a cell set. Pairs of synapse cells relate cell sets, each synapse cell having O and E values of one cell set and A and V values equal to the E and O values of the other cell set. Cell generations store information about attributes, entities, relationships, constraints, and default data formats in the same cell listing as the cells containing the actual real-world data. As a result, the data in a data cell can be considered self-identifying. The present invention also provides a way to normalize data using data pool cell sets. The data cells themselves can be stored in multiple, co-existing storage trees that are specialized for increased data query efficiency.

Abstract: A system and method for obtaining prints or other services from a digital camera uses a camera and a transceiver module, each having unique identifiers that are stored in a database stored on a remote print routing server. To obtain the service, the user couples the camera to the transceiver module and requests an image service, such as by pressing a button. The transceiver module sends image files and a request for prints to the routing server. The routing server confirms that the request is authorized by querying its database to determine if the camera identifier is authorized for use with the transceiver module. Provided the service request is authorized, the routing server sends the image files to a print center. The service request is coupled with shipping and billing information, such that the print center is able to ship prints to the shipping address and bill the appropriate account.

Abstract: An intravascular catheter with micro spines that penetrate arterial wall to delivery drug or mechanical injury to the vessel wall inducing a “stent” like healing process in the vessel.

Abstract: A mapping catheter is positioned in a heart chamber, and active electrode sites are activated to impose an electric field within the chamber. The blood volume and wall motion modulates the electric field, which is detected by passive electrode sites on the preferred catheter. Electrophysiology measurements, as well as geometry measurements, are taken from the passive electrodes and used to display a map of intrinsic heart activity.

Abstract: A fiber channel backplane configuration is capable of modular expansion, e.g., from 64 ports to 128 ports or 256 ports by a simple operation. The backplane includes connectors that provide permanent and jumper/vertical connections to support 64 user port switch in a single chassis. For a 128 port switch, two 64 port chassis are used. In the 128 port configuration, the connectors are configured to provide permanent and jumper/vertical connections to make intra-chassis and inter-chassis connections between the fabric switch and fabric input/output boards. Using jumper plugs, the jumper connectors provide vertical connections between the fiber input/output boards and fiber switch boards of two chassis. For a 256 port switch configuration, four 64 port chassis assemblies are used. The connectors are configured to provide each switch with permanent, vertical, horizontal, and diagonal connections to the fiber input/output boards of each of the four chassis.

Abstract: A device for converting at least four parallel data streams on respective input data lines into one serial data stream on a fiber optic data line. The device includes a first multiplexer for multiplexing at least two of the parallel data streams into a first intermediate output stream and a second multiplexer for multiplexing at least two other of the parallel data streams into a second intermediate output stream. A serializing transmitter is coupled to the first and second multiplexers for serializing the first and second intermediate output streams into the serial data stream. A signal synchronizes the serializing of the first and second intermediate output streams and tags output data in the serial data stream as corresponding to data from each of the respective input data lines. In-band messaging is used to transfer commands and status messages between devices without affecting ongoing data stream communications.

Abstract: The present disclosure is directed to a method and system for analyzing network performance by creating benchmark test results when the computer network is initialized, and subsequently testing the network while operational to determine degradations. This method and system can proactively determine problems before they result in network failures, or immediately detect network failures even before the user is aware of them. In one aspect, the disclosure is directed to a method of monitoring at least one computer network from a remote location. The method includes benchmark-testing at least one computer network with test data provided from the remote location to obtain benchmark test results. Often, benchmark-testing is performed when the network is initialized. Once operational, the remote location will perform operational-testing of at least one computer network with sample data provided from the remote location to obtain operational test result.

The cyclone inlet comprises a blood inlet channel that extends in a helical circular form developed to narrow in funnel like manner in the direction of flow toward the cyclone eddy chamber to accelerate the blood flow entering that chamber tangentially. A gas outlet is arranged in the radially inner center of the cyclone eddy chamber path while the blood outlet is coaxial and outward of the gas outlet.

Abstract: A method of constructing a mapping catheter is described where the catheter has numerous electrodes each associated with a single connection in a plug. The method consists of first arranging a plurality of wires in the desired relationship, with each of the wires running to a connection in a plug. Next, a single electrode is formed on each wire. Because it is often difficult to associate a particular connection with a particular plug, an electrical signal is then applied to a single one of the wires. The electrical signal can be applied to the connection or to the electrode. The electrical signal is then found among by examining either the electrodes or the connections, depending on which where the electrical signal was applied. Once the electrical signal is discovered, a map can be made between the connections and the electrodes.
