Scan architecture for full custom blocks with improved scan latch
A non-fighting fully clocked scan latch is described that is dynamically configurable to support both logic data latching and scan data latching. The described scan latch circuit design reduces a load placed on a logic data latch portion of the described circuit by a scan latch portion of the described circuit, and thereby increases the speed of the described scan latch to that of an output latch without scan capability. Power required to drive the described scan latch is reduced by clocking the circuit to avoid fighting and by reducing the number of transistors included in transistor stacks internal to the scan latch. By reducing drive power requirements, eliminating internal latch fighting, and increasing latch response, a versatile scan latch is achieved that may be successfully implemented in a wide range of circuits despite the use of different supply drive voltage, threshold voltage, source-to-drain voltage, and transistor technology combinations. |

Source packet bridge
A communication function between ports on a node that does not require a common time base to be distributed across the network is disclosed. A data stream received over a first port is placed on an interlace between nodes using the time base of the first port; a second port samples the data stream on the interface and timestamps it using the time base of the second port. The data stream is timestamped by the second port and packetized before transmitted to the second node to another bridge or device. Alternatively, the first port extracts a time stamp from the data stream and calculates an offset using a cycle timer value from the bus connected to the first port. The offset is added to the cycle timer value on the bus connected to the second port and used to timestamp the data stream. |

Large-surface defect detection by single-frame spatial-carrier interferometry
An adaptive algorithm is tailored to fit the local fringe frequency of single-frame spatial-carrier data under analysis. Each set of data points used sequentially by the algorithm is first processed with a Fourier Transform to find the local frequency of the fringes being analyzed. That information is then used to adapt the algorithm to the correct phase step thus calculated, thereby optimizing the efficiency and precision with which the algorithm profiles the local surface area. As a result, defects are identified and measured with precision even when the slope of the surface varies locally to the point where the algorithm without adaptive modification would not be effective to measure them. Once so identified, the defects may be measured again locally with greater accuracy by conventional temporal PSI. |

Method for relaying between a base station and a mobile station
Disclosed is a cooperative relay station that relays between a base station and a mobile station when retransmitting a signal. Also, disclosed is a base station that receives a signal from a mobile station in mutual cooperation with the cooperative relay station. After the cooperative relay station receives and decodes a signal that the mobile station transmits to the base station or a service relay station, if an error of the decoded signal does not exist, it stores the received signal. If an error occurs when the base station decodes the signal that the mobile station transmits, the base station requests retransmission for the signal with the error to the cooperative relay station. If the cooperative relay station gets a request of retransmission, it transmits the signal that the base station requests to the base station. In this was, since an error rate may be reduced when the base station requests retransmission of the signal, resource reuse efficiency may become improved, interference may be reduced, and it is easy to adapt to a service being sensitive to time delay. |

A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network.

Optical module
The present invention relates to an optical module having a structure for reducing adverse contingencies such as increased number of fusion splicing points, drops in output, and higher costs associated with a greater number of optical components. The optical module comprises an amplification optical fiber, a transmission optical fiber, and a fusion splicing structure that fusion-splices the amplification optical fiber to the transmission optical fiber, in a state where a cover layer is removed at the tip portions, including the end faces, of these optical fibers. The fusion splicing structure includes a pumping light removing resin that covers directly the tip portions of the amplification optical fiber and the transmission optical fiber from which the cover layer is removed. The pumping light removing resin has a higher refractive index than a first cladding of the amplification optical fiber. The above configuration allows transmitted pumping light, for which the confinement effect by the first cladding of the amplification optical fiber is cancelled, to escape more efficiently out of the fusion splicing portion. |
