  • Publication number: 20100020763
    Abstract: To provide a technology with which a large number of wireless communication networks can be efficiently used while the size of a device operated by a user is reduced and power is saved by providing a communication terminal whose connection with a different wireless communication network can be dynamically reconfigured. A communication terminal 20 whose connection method or the like with a plurality of wireless communication networks can be dynamically reconfigured is provided with a data communication aggregation device 21, a communication application executing device 22, and a local communication path 23 for connecting the data communication aggregation device and the communication application executing device.

  • Publication number: 20090044058
    Abstract: A system for testing a processor. The system includes a gold processor and a test access port (TAP). A processor that is a device under test (DUT) is coupled to both the gold processor and the TAP. In the first mode, the TAP provides test signals to both the gold processor and the DUT while they operate in synchronous functional lockstep. In the second mode, the TAP provides signals to the gold processor. In the third mode, the TAP provides test signals to the DUT. A host computer coupled to the interface control unit executes a software application to cause the TAP to drive test signals and to access test output data from the gold processor and the DUT. Test output data accessed from the gold processor may be compared to that accessed from the DUT to determine any differences. The comparison data generated may then be used for further analysis.

  • Publication number: 20070235329
    Abstract: A device for measuring blood coagulation time is formed from a first substrate; a second substrate; a spacer layer disposed between the first and second substrates, said spacer layer having an opening formed therein defining a sample receiving chamber, a vented sink chamber, and an elongated reservoir forming a conduit for liquid movement between the sample receiving chamber and the sink chamber; a first electrode disposed on the first substrate, said first electrode being exposed in the reservoir portion through a first opening in the spacer layer; and a second electrode disposed on the second substrate, said second electrode being exposed in the reservoir portion through a second opening in the spacer layer. The device of the invention is used in combination with an apparatus that is connected to the first and second electrodes for measuring current flow between the first and second electrodes.

  • Patent number: 7251767
    Abstract: Descriptors are used, which combine the code words of a transmission block of the same correctability into a subset, and which describe the size of the subset as well as the difference in the correctability of the previously concerned subset.

  • Publication number: 20050177448
    Abstract: In one embodiment, establishment of transactions between a plurality of buyers and a plurality of sellers is supported in a network-based marketplace. As part of an invoice generation process, multiple transactions to which a first user of the network-based marketplace is a party are identified. Further, one or more subsets of these transactions that satisfy combinable criteria are identified, and an invoice is generated for at least one of the identified subsets of transactions.

  • Publication number: 20040225606
    Abstract: A method and system to automate payment for a network-based commerce transaction provide a buyer an option to enable an automatic payment service, wherein automatic payment service automatically provides payment to a seller upon a termination event of a network-based commerce transaction. Payment information of the buyer is provided to a network-based payment system upon the occurrence of the termination event.

  • Publication number: 20020059130
    Abstract: Methods and apparatuses for detecting fraudulent activities made over a network-based transaction facility using a machine. In responsive to a first event with respect to the network-based transaction facility and initiated under a first user identity from the machine which is coupled to the network-based transaction facility via a network, the method causes a first identifier associated with the first user identity to be stored on the machine. In responsive to a second event with respect to the network-based transaction facility and initiated under a second user identity from the machine, the method causes a detecting of a potentially fraudulent activity by detecting a lack of correspondence between the first identifier stored on the machine and a second identifier associated with the second user identity.

  • Patent number: 5951705
    Abstract: An integrated circuit tester includes a host computer, a pattern generator and a set of tester circuits. The tester circuits perform test activities on an integrated circuit in response to sequences of test control data arriving via a set of data lines. The host computer may write parameter control data into the tester circuits via a bus telling the tester circuits how to adjust various parameters of test activities to be performed in response to a next arriving sequence of test control data. The host computer is also linked to the pattern generator via that same bus and writes pattern control data into the pattern generator via the bus. The pattern control data tells the pattern generator to generate alternating sequences of test control data and pattern control data. As it is generated, each test control data sequence is delivered to the tester circuits via the data lines to tell the tester circuits how to carry out a sequence of test activities.
