Title: System and method for controlling congestion in multihopping wireless networks
Inventor: OZER SEBNEM Z
IPC: H04L12/28
Filed: 2005-12-14
Abstract: A system and method to control congestion in a multihopping wireless communication network (100). The system and method distribute the congestion information back to the ingress points (106) and traffic source nodes (102, 106, 107) in the network (100) through the actual route of the data flow that contributes to the congestion. The system and method therefore avoid bottleneck points (102-5) in the network (100) to reduce congestion. The system and method can be used for packet-based, route-based or flow-based traffic shaping in a multihop wireless network (100) employing different media access control (MAC) and routing layer protocols. Moreover, the system and method is capable of distributing congestion and service differentiation information between different interfaces in the network (100).

Title: Parametric joint-coding of audio sources
Inventor: FALLER CHRISTOF
IPC: G10L19/008
Filed: 2006-02-13
Abstract: A number of audio source signals need to be transmitted or stored for the purpose of mixing wave field synthesis, multi channel surround, or stereo signals after decoding the source signals. The proposed technique offers significant coding gain when jointly coding the source signals, compared to separately coding them, even when no redundancy is present between the source signals. This is possible by considering statistical properties of the source signals, the properties of mixing techniques, and spatial hearing. The sum of the source signals is transmitted plus the statistical properties of the source signals which mostly determine the perceptually important spatial cues of the final mixed audio channels. Source signals are recovered at the receiver such that their statistical properties approximate the corresponding properties of the original source signals. Subjective evaluations indicate that high audio quality is achieved by the proposed scheme.

Title: Catalyst for purifying exhaust gases
Inventor: SUZUKI HIROMASA
IPC: F01N3/08
Filed: 2006-05-25
Abstract: A catalyst for purifying exhaust gases includes a carrier substrate and a catalyst layer which is carried on the carrier substrate and contains a noble metal, a porous oxide and an addition oxide containing at least one selected from the group consisting of Ni, Bi, Sn, Fe, Co, Cu and Zn. Only a downstream section of the carrier substrate, which is located on a downstream side of an exhaust gas stream contains the addition oxide, whereas an upstream section of the carrier substrate does not contain the addition oxide. With this arrangement, in the upstream section of the carrier substrate, the noble metal and the addition oxide do not exist together so that the noble metal is not deteriorated with the addition oxide. As a result, in the upstream section, the purification performance as a three-way catalyst is favorably achieved, thereby restraining the emission of H2S while maintaining the three-way performance.
