Multiple applications request data from multiple storage units over a computer network. The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. At least one additional copy of each segment also is distributed randomly over the storage units, such that each segment is stored on at least two storage units. This random distribution of multiple copies of segments of data improves both scalability and reliability. When an application requests a selected segment of data, the request is processed by the storage unit with the shortest queue of requests. Random fluctuations in the load applied by multiple applications on multiple storage units are balanced nearly equally over all of the storage units. This combination of techniques results in a system which can transfer multiple, independent high-bandwidth streams of data in a scalable manner in both directions between multiple applications and multiple storage units.

A support member for a catheter sheath is disclosed. The support member has a series of ribs with a distal member having integrated fingers for providing radial compliance. The support member provides sufficient axial stiffness to provide a desired pushability of a minimally invasive device for replacing a heart valve. Various alternative embodiments are also described.

A distributed agent community is able to dynamically interact with alternative sofware technologies that manage distributed objects. The leveraging of capabilities of distributed object systems greatly expands the flexibility and capabilites of the distributed agent community. Through access to distributed object systems, the distributed agent community can draw on the capabilites of all the objects managed by the distributed object systems. The access to distributed systems by the distributed agent community allows for collaboration and intelligent planning that the distributed object systems do not themsleves provide.

A method of thermal ablation using high intensity focused ultrasound energy includes the steps of positioning an ultrasound emitting member, emitting ultrasound energy from the ultrasound emitting member, focusing the ultrasound energy, ablating with the focused ultrasound energy to form an ablated tissue area and removing the ultrasound emitting member.

Disclosed is an RF power transmission network. The network includes at least one RF power transmitter, at least one power tapping component, and at least one load. The at least one RF power transmitter, the at least one power tapping component, and the at least one load are connected in series. The RF power transmitter sends power through the network. The power is radiated from the network to be received by a device to be charged, re-charged, or directly powered by the power.

A peer-to-peer protocol is based on the use of global timestamps and client priorities in serializing modifications to a shared workspace of real-time collaboration. The method caters to dynamic clients wherein a client can leave or join an ongoing collaboration session as long as there is always at least one client present / remaining in the collaboration session. The method can support multiple definitions of a modification, including partitioning-based definitions, wherein the method provides full support for locking of partitions, and a full treatment of inter-partition synchronization via a modification definition over multiple partitions. The method is capable of utilizing the many standard methods of creating a global, distributed, synchronized clock for the global timestamps utilized by it. The method is rollback-based for correcting tentative but incorrect serializations, and provides additional backup in terms of checkpoints for additional safety and for the support of lightweight, pervasive clients. The method includes many optimizations for efficiency, and includes a method of switching to and back from distributed server-based serialization for the periods when the network response is better suited to a distributed server than the peer-to-peer protocol.

A distributed network access system in accordance with the present invention includes at least an external processor and a programmable access device. The programmable access device has a message interface coupled to the external processor and first and second network interfaces through which packets are communicated with a network. The programmable access device includes a packet header filter and a forwarding table that is utilized to route packets communicated between the first and second network interfaces. In response to receipt of a series of packets, the packet header filter in the programmable access device identifies messages in the series of messages upon which policy-based services are to be implemented and passes identified messages via the message interface to the external processor for processing. In response to receipt of a message, the external processor invokes service control on the message and may also invoke policy control on the message.

A flash memory device according to the present invention includes a semiconductor fin including a top surface and a side surface originated from different crystal planes. The flash memory device comprises: insulating layers having different thicknesses formed on a side surface and a top surface of the semiconductor fin, a storage electrode, a gate insulating layer and a control gate electrode sequentially formed on the insulating layers. A thin insulating layer enables charges to be injected or emitted through it, and a thick insulating layer increases a coupling ratio. Accordingly, it is possible to increase an efficiency of a programming or an erase operation of a flash memory device.

A system and a method for charging for directed provisioning and using of dynamic content to limited resource devices, through an integrated platform which handles all aspects of aggregation and management of such dynamic content. The integrated platform features a billing system for performing billing actions. The billing system of the present invention interacts with other components of the integrated platform in order to be able to determine the charge for particular triggering events, such as downloading dynamic content, and / or events which are actually triggered by the application itself. The charge is preferably determined according to one of a plurality of rules, as applied by a rules engine of the billing system. These rules are part of a charging policy, which may optionally be determined by the content provider.

A method, system and apparatus for routing data through a network based on the content or semantics of the data. Semantic routing engines route the data through the network based upon information maintained in routing tables. The routing tables used to route the content through the network are derived by aggregating information about either content consumers or content producers into ontological
