Title: Apparatus for papr reduction and method for operating the same
Inventor: YOU SEUNG HEE
IPC: H04L27/26
Filed: 2008-12-05
Abstract: PURPOSE: An apparatus for PAPR(Peak-to-Average Power Ratio) reduction and a method for operating the same are provided to restore transmission information without specific process by using a(tone reservation) TR technique. CONSTITUTION: A tone assignment part(10) generates a subcarrier of the whole N by inserting L reservation tone signals into the code N-L information signals. A reverse Furier transform(20) processes N subcarrier through inverse Fourier transform. A parallel-serial converter(30) outputs an output signal of the reverse Furier transform unit as the output signal of a time domain. A PAPR decreasing sequence look up table stores the PAPR decreasing sequence loaded to the inserted reservation tone signal. The PAPR decreasing sequence selecting unit(40) calculates PAPR of the output signal to which the PAPR decreasing sequence is added. The PAPR decreasing sequence selecting unit adds PAPR decreasing sequence having lowest PAPR to the output signal.

Title: Rotor blade for a wind power plant
Inventor: WOBBEN ALOYS
IPC: F03D1/06
Filed: 2003-12-19
Abstract: The invention relates to a rotor blade for a wind power plant, which has an aerodynamic profile comprising a rotor blade leading edge and a rotor blade trailing edge. The invention also relates to a rotor blade tip for a rotor blade having an aerodynamic profile with a pressure and a suction side, said rotor blade tip being bent or offset in its end section in the direction of the pressure side of the rotor blade. The aim of the invention is to further reduce noise emission of wind power plants. For this purpose, the rotor blade, in its end section, is bent or offset in the rotor blade plane in the direction of the trailing edge of the rotor blade. The invention is based on the finding that in a rotor blade whose tip is not pointed the effective rotor blade surface remains unchanged exactly in the exterior section where it is most efficient. By bending or offsetting the end section of the rotor blade, the trailing edge in the end section of the rotor blade is displaced backwards so that the current on the rotor blade trailing edge tears off in the outer section with a delay. Alternatively, the rotor blade tip can be embodied in such a manner that theexterior section is pointed. This embodiment of the rotor blade tip is based on the finding that the reduced blade depth results in a reduced air current around the blade tip since its energy is distributed across the trailing edge vortices while the effective rotor blade surface is reduced at the same time. By offsetting the rotor blade tip the effective rotor blade depth remains optimal up to the offset rotor blade tip. ® KIPO & WIPO 2008

Title: Press felt for papermaking
Inventor: ONIKUBO AKIRA
IPC: D21F7/08
Filed: 2007-01-31
Abstract: This invention provides a press felt (10) for papermaking, comprising a substrate (30), a wet paper-side vat layer (20) and a press-side vat layer (23). The wet paper-side vat layer (20) comprises a wet paper contact-side vat layer (21) and a substrate-side vat layer (22). The wet paper contact-side vat layer (21) comprises a core-sheath composite fiber (41) comprising a core component of a high-molecular weight nylon having an absolute viscosity of not less than 80 mPa.s and a sheath component of a nylon having a lower melting point than the core component. The substrate-side vat layer (22) comprises a layer of a nylon fiber (42) free from the core-sheath composite fiber (41). The sheath component of the core-sheath composite fiber (41) is melted to render the wet paper contact-side vat layer (21) dense, and, consequently, moisture in the press-side vat layer (23) is less likely to be moved to the wet paper side, whereby a remoistening phenomenon can be suppressed. Further, since the substrate-side vat layer (22) comprises a nylon layer free from the core-sheath composite fiber, the balance among smoothness, defiber resistance, abrasion resistance, compression fatigue resistance, and water drainage is good.

Abstract: A network system includes a plurality of LANs and a center server which are connected to WAN, wherein each of the LANs is connected to a plurality of facility devices, each having an identifier-equipped object and local servers. Each of the local servers has a routing table where an identifier transmitted from each facility device in the LAN is registered. When a request for executing an object using an identifier is made from one of the facility devices to another facility device, it is checked whether the identifier is registered in the routing table. If yes, the object execution request is transmitted to the corresponding facility device. If no, the object execution request is transferred to the center server. The center server searches a local server of another LAN having correspondence with the identifier and transmits the object execution request.

Title: Communications methods and apparatus using physical attachment point identifiers which support dual communications links
Inventor: LAROIA RAJIV
IPC: H04L12/28
Filed: 2006-12-20
Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.
