Abstract:

The embodiment of the present invention discloses a method for establishing a multicast LSP and a system for transmitting multicast data. The method includes: a MSA node learns and stores multicast stream information; the egress edge node in the MPLS domain obtains the multicast stream information sent by the MSA node by sending a query request message to the MSA node; the egress edge node joins the multicast group, according to the obtained multicast stream information, and establishes a multicast LSP between the ingress edge node and the egress edge node. The technical solution of the present invention supports dynamic implementation of multicast services, and reduces the cost of maintaining a network topology.

Description:

FIELD OF THE INVENTION

The present invention relates to the field of network communication technologies, and, in particular, to a method for establishing a multicast Label Switched Path (LSP) and a system for transmitting multicast data.

BACKGROUND

With the maturity of the Multi-Protocol Label Switching (MPLS) related standards and the popularization of the network multimedia applications, such as IPTV and videoconference, multicast technologies are applied to support the point-to-multipoint and multipoint-to-multipoint communications in a MPLS network, which has become an effective technical method for reducing bandwidth consumption and improving the Quality of Service (QoS).

In the conventional MPLS multicast application solution, a Label Switched Path (LSP) can be established in two ways: (i) a downstream node sends a label mapping to an upstream node to establish a LSP; or (ii) an upstream node receives a request of joining a multicast group from a downstream node, and allocates a label to the downstream node to establish a LSP. The two conventional methods are elaborated below with reference to the accompanying drawings.

As shown in FIG. 1, in a MP ...

Abstract:

A method and apparatus for providing performance measurements on network tunnels in packet networks are disclosed. For example, the method establishes two tunnels between a first measurement host and a first router, and establishes a tunnel between the first router and a second measurement host. The method also establishes a multicast group having a plurality of members, and sends one or more packets addressed to the multicast group from the first measurement host. The method measures the frequencies of directly and/or indirectly received responses from the plurality of members of the multicast group, and provides a plurality of estimated values for a plurality of packet transmission rates from measurement of the frequencies for one or more of said tunnels.

Description:

The present invention relates generally to communication networks and, more particularly, to a method and apparatus for providing performance measurement for network tunnels in networks, e.g., packet networks.

BACKGROUND OF THE INVENTION

When a network performance trouble is detected or received by a network service provider, the service provider is expected to diagnose the network, to identify the cause and to perform remedial steps. However, the reported or detected trouble is typically for an end-to-end network connection. For example, packets for a customer may traverse several networks, e.g., one or more Local Area Networks, IP networks, Asynchronous Transfer Mode (ATM) or Frame Relay (FR) networks, etc. prior to reaching their destination. The customer may not be able to identify the portion of the network responsible for the performance trouble. In order to identify network troubles, the service provider may actively measure one-way performance levels for paths between switches and/or routers. Here, active one-way measurement on a path entails participation by both of its endpoints, measurement packets being produced by o ...

Abstract:

A plurality of PLC adapters, such as a master 21 and slaves 22, are connected to a power line 11, which forms a PLC logic network 16. Electric apparatuses 48, such as a television monitor and a video recorder, are connected to the master 21 and the slaves 22 through repeaters 31. The master 21 is a control terminal having the function of QoS controller. The master 21 allocates timeslots for transmitting data over a network, acquires information on the actual data transmission rate detected by a data receiving terminal, and modifies the timeslot allocated to target data on the basis of the acquired information on the actual data transmission rate.

Description:

TECHNICAL FIELD

The present invention relates to a method and apparatus for controlling a transmission rate and an integrated circuit for controlling a transmission rate that are used in power line communication transmitting stream data such as moving pictures or voices.

BACKGROUND ART

For instance, there has been proposed a system that facilitates communication among a plurality of apparatuses by connecting information apparatuses, such as personal computers, and electric apparatuses, such as television monitors, recorders, video players, and Internet Protocol (IP) telephones, with one another in buildings over a predetermined communication network. However, when data communication is performed through wired communication in buildings, cables or connectors used as transmission paths need to be typically installed at necessary positions. Therefore, a complicated construction work may be needed to construct communication systems.

Since commercial electric power sources, e.g., AC 120V (60 Hz) or 100V (50/60 Hz), are used in most houses, power lines used for supplying power are installed in the houses beforehand. Accordingly, when the power lines can be utilized as transmission paths for data communication, it is not necessary t ...

The system utilizes computer communications network-based systems, software, various input and output stations, and a patient identification card (e.g., Loyalty Card) that work together to allow (a) providers to direct, track, and optimize the efficiency of patient activity and (b) patients to have ready access to their status and, in some cases, control of the healthcare process.

Description:

FIELD OF THE INVENTION

The invention relates generally to the fields of healthcare and information technology. More particularly, the invention relates to a system for managing patients in a healthcare facility.

Abstract:

An information-processing device and method that attains speech-recognition to recognize data input via speech. The information-processing device and method includes analyzing speech-recognition-grammar data, generating data on a template used to input data by speech based on the analysis results, and displaying the generated speech-input-template data.

Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an information-processing device configured to attain speech recognition to recognize data input by speech.

2. Description of the Related Art

Speech-recognition technologies have become commercially practical as technologies of achieving data input and/or device operations through speech input in place of key input and/or button operations. According to many speech-recognition technologies that are currently used, only predetermined words and/or phrases can be recognized, even though the number of words varies depending on the technology. Therefore, it is difficult for a user to know what kind of words and/or phrases can be accepted at the time when the user performs speech input. Accordingly, there have been proposed speech-recognition systems capable of presenting data on words and/or phrases that can be input by speech to the user to perform the speech input smoothly.

For example, Japanese Patent Laid-Open No. 2000-181488 discloses a speech-recognition device presenting a specific input example such as “Input data such as Showa-machi, Kariya city, Aichi prefecture” at the time when address data is input by speech. Further, a speech-recognition device disclosed in Japanese Patent Laid-Open No. 2005-283797 is configured to present input-template data to the user, where the data is used to correct speech-input data on continuous numbers when the speech-input data is erroneously recognized. For example, the input-template data ...

Electric motor and controller assembly with integrated sensor device

Abstract:

The device and method of the present invention improves electronic communication which have behavioral consequences, including for example, flight communication, two-way closed circuit communication such as for fire, police, miners, scuba divers and other heath and safety workers, and even for mobile communication which happens during activities such as cellular or mobile conversations during driving. Dichotic listening techniques are altered to enhance dyadic (involving two people) interactions with a partner. The speech of at least the first member of the dyad is filtered to isolate the component below 0.5 Khz, which will be input with a gain to the left ear of the second person (provided that they are right-handed), and thus their right cerebral hemispheres, and the component with a frequency above 0.5 Khz. will be input to their right ears, and thus their left cerebral hemispheres. The apparatus of the invention includes a communication source, which could include live and simultaneous broadcast, or pre-recorded communication. This constitutes the communication input which is directed to a filter to split off the speech fundamental frequency, i.e. the SFF. The post filtered communication signal, or “SFF augmented signal” is fed to a differentiation device which differentiates two signals, one with an enhanced SFF, and one without the enhancement subsequently, a delivery device delivers the now differentiated left and right signals to the appropriate ears.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a timing analysis method and apparatus. More particularly, the present invention relates to a timing analysis method and apparatus for large-scale integrated circuits.

2. Description of the Related Art

Recently, extremely accurate timing analysis has been required in designing recent ultra-high-speed LSIs that operate at clock frequencies exceeding several GHz.

Epitrochoidal electric motor

Abstract:

Embodiments of the present invention provide a finite difference method, a finite element projection, and a non-finite-element implementation of the finite element projection for solving the incompressible continuity equation on quadrilateral grids to obtain pressure and fluid velocity. An exemplary apparatus for simulating and analyzing the flow of an incompressible fluid is also provided. More particularly, embodiments of the present invention provide a non-finite-element-method (non-FEM) to implement the finite element projection to obtain a linear system whose coefficient matrix has an average bandwidth of five, in comparison to the finite difference scheme using conventional finite element projection and implementation with a bandwidth of nine. A two-dimensional-five-point-stencil-based non-FEM discretization is formulated to enforce the incompressible continuity equation. A shape function that is different from a weighting function used in the incompressible continuity equation is utilized to guarantee the five-point-stencil discretization is possible. The smaller bandwidth of the non-FEM scheme requires less computing resources and can compute the results in a reduced time duration, due to the simpler matrix to solve.

Abstract:

The present disclosure is concerned with the identification of fault origins of slowly degrading systems such as industrial gas turbines. Following the initial input of some parameter values, exemplary procedure comprises a number of steps which are repeated periodically during the operation of the gas turbine. First, for each potential fault such as e.g. a contamination of compressor blades, erosion of turbine blades or corrosion of machine parts, a pre-symptom fault probability, characteristic of the specific gas turbine considered, and a symptom-conditional fault probability are calculated. In a second step, on-line data from the monitoring devices are loaded in order to update information about symptoms such as e.g. reductions in polytropic efficiency and in flow capacity, changes in vibration spectrum, or other machine condition indicators, and a post-symptom fault probability is calculated. In a third step, the calculated fault probabilities are displayed and transmitted to a planning system for scheduling of gas turbine operation or maintenance actions.

Description:

TECHNICAL FIELD

The disclosure relates to the field of control and instrumentation technology for turbomachines such as gas turbines or internal combustion engines. It departs from a method of monitoring a specific degrading system of a general system type suffering from a plurality of faults.

BACKGROUND INFORMATION

A turbomachine such as a gas turbine or an internal combustion engine is a system subject to considerable loads. Creep and fatigue affect the machine in extreme conditions due to very high combustion temperatures, pressure ratios, and air flows. As a consequence of their deterioration, the main components of a gas turbine (GT), i.e. the inlet nozzle, the compressor, the combustion chamber, the turbine, the air flow cooler, and the outlet, all contribute—to a different extent—to the degradation of GT pe ...

Rotating electric machine and manufacturing method therefor

Abstract:

A semiconductor integrated circuit according to the examples of the present invention is applied to a system using a first power source voltage and a second power source voltage independent of the first power source voltage and includes a first area to which the first power source voltage is supplied, a thermal sensor placed in the first area, and a first input path placed in the first area, for transferring trimming data that determine the control contents of the thermal sensor to the thermal sensor.

Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the trimming of the temperature control contents of an on-chip thermal sensor (thermometer assembled in a chip).

2. Description of the Related Art

Highly efficient semiconductor integrated circuits execute computations in parallel with each other at a high speed, from which a problem arises in that a chip temperature is increased.

When the chip temperature becomes higher than a certain limit, the transistors in the chip becomes in danger of breakage or firing. Therefore, technologies for controlling the chip temperature and preventing these failures of transistors are required.

One of the technologies is to assemble a thermal sensor in a semiconductor integrated circuit and to reduce a computation speed or stops a computation itself when a chip temperature exceeds a predetermined value (refer to, for example, Jpn. Pat. Appln. KOKAI Publication No. 10-41466).

In the technology, a trimming data which determines the temperature control contents of a thermal sensor is stored in a fuse circuit after a trimming test is executed to calibrate the temperature of the thermal sensor, for example, before a product is shipped.

However, in a conventional trimming test, since a signal path used in a normal operation is used as it is, a power source voltage is supplied to a core ...

Electrical machine having an apparatus for avoiding damaging bearing currents, and a corresponding method

Abstract:

A system and associated method for evaluating a high-frequency signal at a point of interest on a signal path from a remote signal at a remote pickup point on the signal path. The point of interest is located on a device under test that is coupled to test equipment via the signal path. The high-frequency signal at the point of interest is calculated from the remote signal at the remote pickup point with an inverse transfer function that eliminates degradation effects on the high-frequency signal that is transferred through the signal path. The inverse transfer function may be calculated from measurements acquired in a test signal transfer through a reference path that simulates electrical properties of the signal path, or configured to a predetermined function if electrical properties of the signal path are known.

Description:

FIELD OF THE INVENTION

The present invention discloses a system and associated method for improved probing of electrical signals and accurate measurements thereof.

BACKGROUND OF THE INVENTION

Conventional test probes employing a direct measurement of signals at points of interest have difficulties in testing modern electrical machines embedding multiple physical devices, because sizes of the embedded physical devices become smaller and higher frequency signal bandwidths are required for increased speed properties of smaller embedded physical devices. It is difficult or impossible to pick up test signals at the points of interest by direct manual probing. Even when an embedded device can be operated in a probing environment, because signal traces between conventional test probes and the embedded device are typically needed to transfer stimulating and resulting signals, degradation along each signal trace may significantly impact electrical signal fidelity. The difficulties in direct manual probing and inaccurate results of such direct manual probing cannot be easil ...

Rotating electrical machine

Abstract:

Methods, systems, and programs for monitoring operation of one or more pressure relief valves, each relief valve containing an internal flow passage with a valve seat and valve plug disposed therein. The temperature of a fluid is sensed in the internal flow passage downstream of the valve seat. A valve temperature signal is generated representative of the temperature of the fluid downstream of the valve seat. The valve temperature signal is monitored to detect a rate of change in the temperature of the fluid downstream of the valve seat. The internal pressure of an inlet pressure line is sensed, connected to the internal flow passage upstream of the valve seat. A line pressure signal is generated representative of the internal pressure of the inlet pressure line. The line pressure signal is compared against at least one expected line pressure value to determine a line pressure status. Operational status of the pressure relief valve is determined based at least in part on the detected rate of change of the fluid temperature downstream of the valve seat and at least in part on the determined line pressure status.

FIELD OF INVENTION

The present invention relates to RNA interference (“RNAi”).

BACKGROUND OF THE INVENTION

Relatively recently, researchers observed that double stranded RNA (“dsRNA”) could be used to inhibit protein expression. This ability to silence a gene has broad potential for treating human diseases, and many researchers and commercial entities are currently investing considerable resources in developing therapies based on this technology.

Double stranded RNA induced gene silencing can occur on at least three different levels: (i) transcription inactivation, which refers to RNA guided DNA or histone methylation; (ii) siRNA induced mRNA degradation; and (iii) mRNA induced transcriptional attenuation.

It is generally considered that the major mechanism of RNA induced silencing (RNA interference, or RNAi) in mammalian cells is mRNA degradation. Initial attempts to use RNAi in mammalian cells focused on the use of long strands of dsRNA. However, these attempts to induce RNAi met with limited success, due in part to the induction of the interferon response, which results in a general, as opposed ...

Molded motor and electric vehicle

Abstract:

A method of detecting a changed condition within a geographical space from a moving vehicle. Images of that geographic space are memorialized in conjunction with GPS coordinates together with its GPS coordinates. The same geographic space is traversed from the moving vehicle while accessing the route"s GPS coordinates. The memorialized images are played back by coordinating the GPS data on a memorialized images with that of the traversed geographic space such that the memorialized images are viewed simultaneously with the geographic space being traversed. An observer traveling within the moving vehicle can compare the memorialized images with those being traversed in order to identify changed conditions.

FIELD OF THE INVENTION

Video is typically recorded by time, for example, 30 frames per second. By selecting which frames to record and or use according to GPS of the camera position or according to distance traveled, a new database is created. This video or sequential image database incorporates geographically referenced images that are spatially related rather than time related. By the selection of a distance between frames to identify which frames are to be acquired rather than time, a dramatically smaller database results that is able to be searched more easily. This provides for a dramatically reduced size in the database and is a technique of data compression. Specific frames or data can be more easily retrieved by geographic position that can be determined by global position satellites, inertial systems or other electro mechanical sensors. Traditionally, forward looking video views have not been recorded by distance traveled or relative geographic position. They are separated by time rather than distance. The present invention involves a navigation and inspection system having particular utility for a more precise form of vehicle navigation or inspection of nearby objects. For exam ...

Recently, rapid increase in traffic demands causes traffic congestion and economic loss (e.g. loss of energy) due to poor distribution of products. Furthermore, in spite of such traffic congestion, an increasing number of vehicle drivers violate traffic regulations (e.g. regulations related to speeding, signals, or lanes), in order to reach their destination quickly. The resulting increase in traffic accidents has become another social problem.

In order to solve such problems, new roads must be constructed in accordance with the increase in traffic demands. However, constructing new roads needs a vast amount of funding and time, and there are man ...
