摘要:
A system and method are disclosed for eliminating many of the transactional performance limitations in current digital media server systems by augmenting those existing systems with an adaptable cache. In a preferred embodiment, the adaptable cache is a compact storage device that can persist data and deliver it at an accelerated rate, as well as act as an intelligent controller and director of that data. Incorporating such an adaptable cache between existing storage devices and an external network interface of a media server, or at the network interface itself, significantly overcomes the transactional limitations of the storage devices, increasing performance and throughput for the overall digital media system. The adaptable cache of the present system and method may preferably be integrated directly into the storage and delivery pipelines, utilizing the native communications busses and protocols of those subsystems.

The present invention provides an apparatus and method for recovering the core (108) of a subterranean sheathed electrical cable (106), while minimising the impact on the surrounding environment. The apparatus comprises a ram (102) operable to exert a pushing force on the core of a length of the cable, a plurality of linkages, each linkage being configured to be insertable into the cable along its length under the action of the ram to displace the core relative to an outer sheath of the cable, and a puller operable (104) to exert a pulling force on the core to thereby facilitate removal of the displaced core from the outer sheath by action of the pushing/pulling forces. The apparatus and method are found to be particularly suited to the recovery of high-tension copper core cables, while enabling any hydrocarbon (e.g. oil) impregnated inner sheathing to be controllably disposed of without hazard to the environment.

A system and method are disclosed for facilitating fast-forwarding by viewers through a first-run program beyond the current broadcast point. In one embodiment, the first-run program is distributed before its scheduled publication time, and may be viewed at any time after the publication time. In a second embodiment, content is distributed on or after the publication time, but at a rate greater than the normal viewing rate. In a third embodiment, content is distributed on demand after the publication time by a media distribution server. In a fourth embodiment, a viewer participating in a multicast session of the content requests content beyond the current broadcast point. The viewer is switched to a unicast session, and the requested content is transmitted to the viewer. In alternative embodiments, a release code may be provided to control the time after which the viewer will be permitted to view program segments beyond the current broadcast point.

摘要:
The present invention provides an apparatus (100) and method for cooling and recovering heat energy from power cables and/or transformers. The apparatus (100) comprises a first conduit (102) in thermal contact with at least one electrical power cable (104) and/or at least one transformer, a heat transfer device (106) coupled to the first conduit (102), fluid circulating means (112) and a heating circuit (114) coupled to the heat transfer device (106) for interfacing with an external heating system (126), such as those typically installed in domestic or commercial premises (128). When in use, the circulating means (112) is operable to circulate a fluid through the first conduit (102) to thereby enable the heat transfer device (106) to recover at least a portion of the heat energy of the cable (104) and/or transformer from the heated fluid for subsequent reuse by an external heating system (126) via the heating circuit (114). The apparatus and method are found to be particularly suited for the recovery and reuse of wasted heat from subterranean high-tension power cables and above surface substation transformers, while cooling the equipment to improve operational performance and lifetime.

An organic thin film transistor comprising: a substrate; a source electrode and a drain electrode disposed over the substrate with a channel region therebetween; a layer of organic semiconductor disposed in the channel region; a gate electrode; and a gate dielectric disposed between the layer of organic semiconductor and the gate electrode, wherein the gate dielectric comprises a cross-linked polymer and a fluorine containing polymer.
摘要:
A system and method for load balancing a plurality of servers is disclosed. In a preferred embodiment, a plurality of servers in a video-on-demand or other multi-server system are divided into one or more load-balancing groups. Each server preferably maintains state information concerning other servers in its load-balancing group including information concerning content maintained and served by each server in the group. Changes in a server's content status or other state information are preferably proactively delivered to other servers in the group. When a content request is received by any server in a load-balancing group, it evaluates the request in accordance with a specified algorithm to determine whether it should deliver the requested content itself or redirect the request to another server in its group. In a preferred embodiment, this determination is a function of information in the server's state table.
