| 20090185573 | PSUEDOWIRE TERMINATION DIRECTLY ON A ROUTER - A method, apparatus and computer program product for routing data within a packet-switched network using a PW wherein the PW is terminated directly on the layer-3 routing device such that certain services and applications can be utilized is presented. The method, apparatus and computer program product receives an encapsulated layer-2 Protocol Data Unit (PDU) from a pseudowire emulating a service. The encapsulation is removed from the encapsulated layer-2 PDU and a layer-2 circuit associated with the pseudowire is terminated. The circuit is treated as an interface and the PDU is forwarded based on upper layer protocol information within the PDU. | 07-23-2009 |

| 20100329349 | EFFICIENT USE OF STORAGE IN ENCODING AND DECODING VIDEO DATA STREAMS - Some embodiments facilitate encoding/decoding of a frame by organizing frame data in a storage structure in a novel manner. Specifically, in a portion of the storage structure allocated for a frame slice, used partition entries are stored in a first section of the allocated portion and unused partition entries are stored in a second section of the allocated portion, the first and second sections each comprising a continuous area of storage in the storage structure so that used partition entries are not interspersed with nonused partition entries. In some embodiments, additional data useful in the encoding or decoding of video data is determined and stored into the unused bytes of used partition entries (such as macroblock header data or canonical reference frame index data). In some embodiments, two or more identical partitions of a macroblock are coalesced into a single partition. | 12-30-2010 |

| 20090310685 | HIGH-YIELD MULTI-THREADING METHOD AND APPARATUS FOR VIDEO ENCODERS/TRANSCODERS/DECODERS WITH DYNAMIC VIDEO REORDERING AND MULTI-LEVEL VIDEO CODING DEPENDENCY MANAGEMENT - Disclosed is an exemplary video coder and video coding method according to an embodiment of the present invention. The exemplary video coder includes a scheduler, a plurality of processors and a multiplexer. The scheduler can examine processing units in an input buffer to determine an order for the processing unit to be coded by a processor. If the processing unit under examination depends on a processing unit not yet processed, the processing unit under examination can be merged with other processing units, if any, that share a similar dependency. If the processing unit under examination does not depend on any processing units not yet processed, it can be sent to a next available processor for coding. When a processing unit is sent to a processor, any merged processing units that depend on sent processing unit can also be sent to a next available processor. | 12-17-2009 |

| 20100080889 | METHOD AND EQUIPMENT FOR THE CONTINUOUS DEPOSITION OF A COATING ON A STRIP TYPE SUBSTRATE - In the continuous deposition of a coating on strip-type substrate, a thickness of the coating depends on the condition of various actuators. A first preliminary phase of the process includes developing a pre-setting model, a second preliminary phase includes developing an adjustment model, an intermediate pre-setting step during which the actuators are set statically, a step of measuring the thickness of the coating, and an adjustment step during which the actuators are dynamically controlled by a predictive control based on the adjustment model in order to reduce any potential difference between the coating measured thickness and a target value of the thickness. | 04-01-2010 |

| 20110241301 | Steering Assembly for a Two-Wheeler - Steering assembly for a two-wheeler comprising a frame, a handlebar and a fork holding a steering front wheel. The steering assembly comprises a head tube rigid with the frame and defining a swivel axis, a steering rod mounted swivelling through the head tube and connected on the one hand to the handlebar and on the other hand to the fork. | 10-06-2011 |
| 20110241307 | Bike with Belt Transmission and its Frame - Bike comprising a first frame element extending from one end carrying a front wheel housing to a lower end, a second frame element extending to a lower end rigidly fixed to the first lower end, a rear fork comprising a chainstay extending from the first element to a spindle support and a seat stay extending from the spindle support to the second element, a crankset having a lateral chainring, a rear wheel driven by a sprocket inside the fork, a belt engaged with the chainring and the sprocket. The chainstay has a major portion arranged below a straight line passing through the lower ends of the chainring and of the sprocket. The belt extends through the triangle formed by the second frame element, the chainstay and the seat stay, which form an irremovable assembly. | 10-06-2011 |
