  • Patent number: 7408359
    Abstract: The current measuring device includes an upper solution chamber (3) and a lower solution chamber (8) whose bottom has a support layer (5) and measures a current flowing via an artificial lipid bilayer membrane (2) formed on a small hole (4) of the upper solution chamber (3), wherein the lower solution chamber (8) is provided below the upper solution chamber (3) by being surrounded with a bottom plate (6) and an interval keeping member (7a). An internal pressure of the lower solution chamber (8) is dropped so that the artificial lipid bilayer membrane (2) formed on the small hole (4) swells to the side of the lower solution chamber (8) so as to be thinner, and the thinner artificial lipid bilayer membrane (2) is supported by the support layer.

  • Patent number: 7405576
    Abstract: Two ends of a transmission line whose electrical characteristics per unit length are known are connected to associated measurement ports of a network analyzer. A short standard is shunt-connected to at least three points in the longitudinal direction of the transmission line, and electrical characteristics are measured in a short-circuited state, thereby calculating error factors of a measurement system. Then an electronic device to be measured is shunt-connected to the transmission line, and electrical characteristics of the electronic device are measured. Then the error factors of the measurement system are removed from the measured values of the electronic device to be measured, thereby obtaining true values of the electrical characteristics of the electronic device to be measured. Accordingly, a highly accurate high-frequency electrical characteristic measuring method that is not affected by connection variations can be implemented.

  • Patent number: 7403018
    Abstract: A cable tester that tests cable and that determines a cable status includes a pretest module that senses activity on pairs of the cable and that selectively enables testing based on the sensed activity. A test module is enabled by the pretest module, transmits a test pulse on one of the pairs, measures a reflection amplitude and calculates a cable length. The cable status includes an open status, a short status, and a normal status. The test module determines the cable status based on the measured amplitude and the calculated cable length. The test module measures received signals on at least one other pair after transmitting the test pulse on the one of the pairs, compares the received signals on the at least one other pair to a predetermined threshold, and determines a pair short status between the one of the pairs and the at least one other pair if the received signals exceed the predetermined threshold.

  • Patent number: 7401002
    Abstract: A method and apparatus for statistical compilation is presented. A statistic component portion for each statistic is stored in each a plurality of banks in a multi-location memory. At least one statistical update stream is received. Each statistical update stream includes a plurality of statistical updates, where each statistical update includes a statistic identifier and an update operand. Received statistical updates are scheduled to produce a scheduled update stream. A control block executes the updates. The control block retrieves the current value of one of the statistic component portions from memory and combines the current value with the update operand of a corresponding statistical update. The resulting updated component value is then stored back into memory. When a processing block issues a statistic request, the control block fetches each of the component portions from memory and combines the component portions to produce a total statistic value.

  • Patent number: 7400130
    Abstract: An integrated circuit device comprises internally on-chip an oscillator with a signal output. The device has a reference clock input, a first counter with a count input, a control input and a counter output, a second counter with a count input, a control input and an overflow indication output, and a test control logic circuit. The count input of the first counter is connected to the signal output of the oscillator. The count input of the second counter is connected to the reference clock input.

  • Patent number: 7401006
    Abstract: The present invention relates to a method and system for processing time series signal data or image signal data indicative of a characteristic of an object. Received signal data are transformed into second signal data within a Stockwell domain based upon a sparse approximation of a S-transform of the signal data. The second signal data are then processed within the Stockwell domain to extract features therefrom. The processing includes determination of local spectra at predetermined locations; determination of voices at predetermined frequencies; and filtering of the signal data using a filter function in dependence upon frequency and time or space. The signal processing method and system according to the invention enables signal processing based on the S-transform using a desktop computer or workstation.

  • Patent number: 7394260
    Abstract: A method of tuning a test trace that is capacitively coupled to a number of signal traces. A method for determining a configuration of a device comprising signal traces and a capacitively coupled test trace may include selecting a test frequency of a test signal to be driven on selected signal traces during a test mode of device operation, and tuning circuit characteristics of the test trace to generate a bandpass frequency response including a passband and a stopband, where a detection frequency corresponding either to the test frequency or a selected harmonic of the test frequency is included in the passband. Tuning of circuit characteristics may include selecting a degree of capacitive coupling between the test trace and the signal traces such that, within a specified constraint for signal degradation on the signal traces, the bandpass frequency response of the given test trace satisfies a specified transmission requirement at the detection frequency.

  • Patent number: 7385405
    Abstract: A capacitance probe for thin dielectric film characterization provides a highly sensitive capacitance measurement method and reduces the contact area needed to obtain such a measurement. Preferably, the capacitance probe is connected to a measurement system by a transmission line and comprises a center conductive tip and RLC components between the center conductor and the ground of the transmission line. When the probe tip is in contact with a sample, an MIS or MIM structure is formed, with the RLC components and the capacitance of the MIS or MIM structure forming a resonant circuit. By sending a driving signal to the probe and measuring the reflected signal from the probe through the transmission line, the resonant characteristic of the resonant circuit can be obtained. The capacitance of the MIS or MIM structure is obtainable from the resonant characteristics and the dielectric film thickness or other dielectric properties are also extractable.
