Title: Fuel cell system and control method thereof
Inventor: NAKAYAMA KEN
IPC: H01M8/04
Filed: 2008-12-23
Abstract: A fuel cell system having a fuel cell for causing reactant gas to be electrochemically reacted to generate power, a reactant gas supply path for supplying reactant gas to the fuel cell, a reactant gas recirculation path for recirculating exhaust gas discharged from the fuel cell and combining the recirculating exhaust gas with reactant gas flowing through the reactant gas supply path to the fuel cell, and a pump unit disposed in the reactant gas recirculation path to pump the recirculating exhaust gas through the reactant gas recirculation path. A pump-tempering apparatus increases the temperature of the pump unit and a controller controls the pump-tempering apparatus.

IPC: G01P5/00
Filed: 2008-12-31
Abstract: Methods and apparatus for fast computation of fluid velocity fields in the presence of objects causing flow discontinuity are disclosed. Rigorous evaluation of perturbed velocity fields, each resulting from placing an object in a bounded space sustaining a reference velocity field, are determined for different orientations of the object with respect to a reference velocity field and different values of the magnitude of the velocity field. A velocity field is determined at selected sampling points within an enclosure surrounding the object. Pre-computed perturbed velocity fields determined for each object of a set of reference objects are stored in a computer memory.  Fast real-time computation of velocity-field perturbations caused by presence of objects at arbitrary positions in a space sustaining velocity fields of different magnitudes and directions are realized using the stored pre-computed data.

Title: Method and apparatus for computing alternate multicast/broadcast paths in a routed network
Inventor: ZHANG HONG
IPC: H04L45/18
Filed: 2007-11-01
Abstract: Alternate multicast/broadcast paths may be calculated in a routed network to enable broadcast/multicast traffic to be transmitted around a local failure in the routed network until the routing system reconverges on a new network topography. According to an embodiment of the invention, the nodes on a multicast tree or a broadcast tree may compute alternate paths for each of the downstream nodes in the multicast/broadcast tree or for select nodes in the multicast/broadcast tree. The select nodes may be those nodes that have advertised membership in the multicast or a set number of hops downstream on the branch affected by the failure. The alternate paths may be unicast paths from the node to the other nodes on the multicast/broadcast tree. U-turn nodes may be used where there is no regular loop-free alternate network path to a node on the downstream multicast/broadcast tree.

IPC: G02B6/255
Filed: 2007-11-13
Abstract: Provided is an optical connector which has an improved characteristic of being stored in a cabinet or the like with reduced sizes, and furthermore, eliminates problems of bending loss increase, breakage and the like of optical fiber. An optical connector (1) stores and holds a fusion-spliced section (13) where a short optical fiber (5) previously attached to an optical connector ferrule (7) and an optical fiber core wire (3) are fusion-spliced. In the optical connector, one end of a protection sleeve (15) housing the fusion-spliced connecting section (13) is coupled to the optical connector ferrule (7). As a result, since the length of the protection sleeve (15), which covers the fusion-spliced section (13) to have the fusion-spliced section (13) at the center, can be set by having the end section of the optical connector ferrule (7) as a reference position, the protection sleeve (15) is shortened and the optical connector (1) is reduced in sizes.
