H04L 12/56

US Classification:

709219, 709227, 709230, 370389

Abstract:

An apparatus and method for defining content distribution paths in a content distribution network integrate unicast and multicast connections. Content engines in the content distributed network are organized into channels with a master content engine maintaining specific content. The content distribution network is further organized into a distribution hierarchy based on network topology and channel definitions, first by establishing unicast paths through the content distributed network and then by integrating multicast paths into the unicast hierarchy. The further organization of the content distribution network establishes distribution trees from the channel masters to the network edges.

International Classification:

H04L 12/28

US Classification:

370390, 370473

Abstract:

A system for reliable multicast distribution includes a primary content engine and a backup content engine sender. The primary content engine sender sends out a multicast message of content to selected content engine receivers. The sender waits for negative acknowledgments from the selected content engine receivers declaring that content was not received. If a negative acknowledgment is received, the sender resends the multicast message a predetermined number of times. If the content is still not received after the number of multicast passes is exhausted, the sender sends out unicast messages to those receivers still requesting content. If the primary sender does not respond to a negative acknowledgment, the receiver sends a second negative acknowledgment to the backup multicast sender. The backup responds with the data requested in the negative acknowledgment and so is able to begin data distribution at the point where the primary sender left off without maintaining synchronicity with the primary sender.

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 7/00

US Classification:

707626, 707637

Abstract:

A system for providing a dynamic portal page in a content distributed network responds to a client request by generating the dynamic portal page at a content engine. The content engine has a portal template with at least one dynamic portion. The content engine writes into the at least one dynamic portion of the portal template links to content cached at the content engine. The content engine also writes into the at least one dynamic portion of the portal template information about availability of content not yet cached at the content engine.

International Classification:

A61B 5/044
A61B 5/0452

US Classification:

600523, 600510, 600522

Abstract:

A system evaluates the performance of an implantable medical device, such as by using a remote external server and a user interface and stored historical physiological data of a population of congestive heart failure (CHF) patients. A processor is coupled to a patient data storage device to apply multiple algorithm variations against the same implantable physiological data from the patient to produce corresponding resulting CHF indicators. The user interface includes a display that is configured to display to a user information allowing comparison between the resulting CHF indicators from the multiple algorithm variations. The display also includes a population data selector to permit the user to select physiological data from a population that includes a different set of one or more patients or physiological data collected over a period of time from the patient. This permits optimization of an algorithm parameter or selection of a best performing algorithm.

International Classification:

A61N 1/362

US Classification:

607 32

Abstract:

This document discusses, among other things, methods and systems for facilitating automated device programming at changeout. A method comprises receiving, from a first device, physiological data at a temporary storage device; and processing the received physiological data, wherein the processing includes determining if a first signal processing function was used by the first device and substantially offsetting the first signal processing function if the first signal processing function was used by the first device; and processing the resultant physiological data to be compatible with a second device. The method further comprising providing the processed resultant physiological data to the second device.

US Classification:

709232

Abstract:

In one embodiment, redundancy elimination for web caching may be provided. Upon receiving a request for a content object, a determination of whether the content object is cached may be made. In response to determining that the content object is not cached, the requested content object may be retrieved and, if the content object is associated with an aggregate popularity exceeding a caching threshold, the content object may be cached before providing the requested content object.
