摘要:
Normal 802.3 Ethernet requires a tree topology. If a ring or a loop exists, then packets will be forwarded around the ring indefinitely. If the ring is broken, then there is no possibility of packets being propagated forever. This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that allows a ring node to bridge user traffic in the case that no switch table entry is present for that traffic. This abstract is provided as an aid to those performing prior art searches and not a limitation on the scope of the claims.

This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that handles a unidirectional break in a communication link where the unidirectional break is not sensed as an OPER DOWN state. This abstract is provided as an aid to those performing prior art searches and not a limitation on the scope of the claims.

The present invention is directed to distal tip designs for catheter, wherein distal tip material is positioned about an inner shaft. The distal tip material may also be used as a tie layer for thermally bonding two incompatible materials together, such as a waist portion of a balloon to the inner shaft.

Methods and apparatus for dynamically determining whether portions of code should be interpreted or compiled in order to optimize a software application during run-time are disclosed. According to one aspect of the present invention, computer-implemented method for run-time processing of a computer program which includes byte-codes arranged as a plurality of methods includes invoking a first method selected from the plurality of methods. Invoking the first selected method involves interpreting the first selected method. An invocation tracker which is arranged to track the number of invocations of the first selected method is updated, and a determination is made regarding when the invocation tracker indicates that the number of invocations of the first selected method exceeds a threshold value. The first selected method is compiled when it is determined that the invocation tracker indicates that the number of invocations of the first selected method exceeds a threshold value. This threshold value is periodically adjusted to keep the compilation and the interpretation overheads within acceptable ranges.

This invention creates an internet-based clearinghouse that enables physicians to electronically create, store, modify, view, and transmit prescriptions using the public internet. Additionally the clearinghouse allows the physician, pharmacy, and patient to communicate electronically on matters regarding prescriptions. All data stored in the prescription database will be accessible to registered users. Access is based on security privilege assigned the user by the clearinghouse. Data stored within the clearinghouse will be accessible anywhere an internet connection exists.
