摘要:
An apparatus comprising a network node coupled to an internal network comprising a plurality of internal nodes and configured to forward a packet designated to the internal network based on service reachability information that indicates at least one of the internal nodes for forwarding the packet to, wherein the service reachability information is sent and updated in a dynamic manner by the internal network. Also included is a network apparatus implemented method comprising receiving service reachability information from an internal network, maintaining the service reachability information in an interior Forwarding Information Base (iFIB), receiving a packet with a public destination address associated with the internal network; and forwarding the packet to appropriate locations in the internal network using the service reachability information in the iFIB.

A direct current cable termination apparatus for terminating a high voltage direct current cable, the apparatus includes a current-carrying device including a terminal portion of the direct current cable, the cable at least including an electrical conductor, a electrically insulating layer located outside of the electrical conductor, and a conductive shield located outside of the insulating layer and the electrical conductor. The apparatus includes a housing including a tubular outer shell with an inner periphery, the outer shell defining a longitudinal axis and being formed by an electrically insulating and polymer-containing material. The current-carrying device extends in the axial direction of the outer shell. Along at least a part of the axial extension of the current-carrying device the outer shell extends axially with a space between its inner periphery and the current-carrying device. The housing is adapted to separate the space from an atmosphere outside the outer shell.

An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit. The apparatus includes a housing, a manifold body, a heat exchanger, and an oxygenator. A blood inlet tangentially directs blood into a first chamber of the housing. The manifold body is disposed in a second chamber, and includes a core and a plurality of vanes that define channels. The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger. The channels are open to the heat exchanger. An established blood flow path includes rotational flow within the first chamber to separate air from the blood, generally longitudinal flow from the first chamber and along the channels, and generally radial flow through the heat exchanger and the oxygenator. With this construction, gross air removal occurs prior to the blood passing through the heat exchanger and oxygenator.

A spectra shaping apparatus for chirped pulse amplification (CPA): uses a spectrum decomposing system with CTSI construction, a spectrum synthesizing system with CTSI structure that is optically symmetrical to the decomposing structure, and a spectrum shaping system including an aperture and a planar reflector for spectrum shaping function design. The apparatus accomplishes the following functions: firstly decomposing the spectrum of a chirped temporal pulse laser to a spectral domain; then shaping the spectrum in the spectral domain; finally synthesizing un-shiftily this shaped spectrum in the spectral domain into a temporal chirped pulse with a designed shape. The apparatus has the feature of fabricating easy, compacting the structure, requiring less space, and cheap in cost etc., which it can be the different types of configuration for different circumstance application, which it can be not only utilized in a general laser spectrum shaping and spectrum modulation, but also can be utilized for a high energy and ultra-high peak-power laser system in chirped pulse amplification with a large caliber and with a chirped pulse bandwidth of a few nanometers.
