摘要： A scalable distributed multimedia streaming system employs at least one media station having a media director and a plurality of media engines. Each media engine incorporates media content storage, communications channels for retrieving and streaming media content over a network. The media director has a controller adapted for directing retrieval over the network of media content by a selected media engine, tracking content stored on the media engines and redirecting a content request from a media console connected to the one media station over the network to a selected one of the media engines storing content corresponding to the request for streaming. Multiple media stations are employed to expand the network using a media location registry as a central repository for storing the location of all media content in the media stations. Intercommunication between the media stations for transfer of content is accomplished through the network.

摘要： A media content distribution system for distributed multimedia streaming communicates over a network and incorporates multiple independent media stations, each having a media director for control and a number of media engines for storage, retrieval and streaming of media content. A content request from a media console connected to the network is redirected by the media director to a selected one of the media engines storing content corresponding to the request for streaming. The system includes at least one distribution center providing media content downloading capability and a media location registry communicating with the media director in each media station. The media location registry stores the location of all media content in the media stations.

摘要： A location update protocol is provided for use in a mobile communications network having a distributed cache for managing subscriber profile information associated with each of a plurality of subscribers of the network. The network includes a plurality of base stations each including a memory unit having a local database for storing: a local subscriber list including a plurality of locally owned cache entries each having an associated subscriber key value, and an associated locally owned subscriber profile; and a global subscriber list including a plurality of global cache entries each having an associated subscriber key value, and an associated location value indicating a node in the network at which an associated subscriber profile is stored. Each of the base stations is operative to transfer and copy selected ones of the cache entries to other ones of the base stations for the purposes of managing and accessing the distributed cache. Each of the base stations is further operative to access an associated mirror base station list indicating at least one associated mirror one of the base stations. The local database of each of the base stations further provides for storage of a mirror subscriber profile list including a plurality of mirror cache entries each having an associated subscriber key value, and an associated mirror subscriber profile. Each of the base stations transfers mirror copies of the associated locally owned cache entries to each of the associated mirror base stations in accordance with the protocol.
摘要翻译：提供位置更新协议用于具有用于管理与网络的多个订户中的每一个相关联的用户简档信息的分布式缓存的移动通信网络。网络包括多个基站，每个基站包括具有用于存储的本地数据库的存储器单元：包括多个本地拥有的高速缓存条目的本地用户列表，每个具有相关联的用户密钥值，以及相关联的本地拥有的用户简档; 以及全球用户列表，其包括多个具有相关联的用户密钥值的全局高速缓存条目，以及指示网络中存储相关联的用户简档的节点的相关联的位置值。为了管理和访问分布式高速缓存的目的，每个基站可操作以将所选高速缓存条目中的一个传送到其他基站。每个基站进一步操作以访问指示基站中的至少一个相关镜像的相关联的镜像基站列表。每个基站的本地数据库还提供用于存储包括多个具有相关联的用户密钥值的多个镜像缓存条目的镜像用户简档列表以及相关联的镜像用户简档。每个基站根据协议将相关联的本地拥有的高速缓存条目的镜像副本传送到每个相关联的镜像基站。

摘要： An implantable pacemaker is provided with a far-field sensing channel which requires a reduced refractory period during the time when pacing pulses are delivered as compared with sensing channels using intra-cardiac electrodes. The far-field sensing channel may use the conductive housing of the implantable device or can and an indifferent electrode mounted on the device header as the electrodes for its differential inputs. Such a far-field sensing channel is able to sense activity occurring in either the atria or the ventricles for the purposes of arrhythmia detection and/or capture verification.

摘要： In an end to end fully internet protocol (IP) enabled network, a dynamic IP address space is used to address mobile hosts in order to facilitate mobility management. The network includes a wireless mobile network having a plurality of base stations each being associated with a portion of the dynamic IP address space. The base stations are operative to allocate dynamic IP addresses from the associated portion of the dynamic IP address space for each authenticated mobile host. Each of the base stations provides translation between the dynamic IP address space and a permanent IP address space so that the dynamic IP address space is transparent from the point of view of the mobile hosts. A gateway provides communicative coupling between the backbone of the wireless mobile network and a wire lined IP network. The gateway also provides translation between the dynamic IP address space and the permanent IP address space.
