摘要： 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.

摘要： In a DOCSIS transmission network, it is necessary for an upstream receiver to estimate and correct for errors in the carrier frequency of the transmission based upon observations of a preamble sequence. This task is complicated by the fact that microreflections in the upstream channels cause intersymbol interference, which tends to bias the frequency estimation circuit. An economical, ISI-immune algorithm is provided for estimating the carrier frequency of upstream transmissions. The arrangement improves the reliability of the frequency estimates in the presence of ISI, thereby reducing the overhead and increasing the throughput of the upstream channels.
摘要翻译：在DOCSIS传输网络中，上游接收机有必要基于前导序列的观察来估计和校正传输的载波频率中的错误。这个任务是复杂的，因为上行信道中的微反射引起码间干扰，这倾向于偏置频率估计电路。提供了经济的ISI免疫算法来估计上行传输的载波频率。该装置提高了存在ISI的频率估计的可靠性，从而降低了上行信道的开销和增加吞吐量。

摘要： 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. Changes in observed current are indicative of flow through the device, and a cessation of flow indicates coagulation.

摘要： 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.
