Abstract: In a parameter correction circuit in an LSI, a reference resistor element with high precision having a resistance value set to a target value is connected to an external terminal of the LSI. A constant current from a mirror circuit connected to a current supply flows through the reference resistor element. A voltage value generated in the reference resistor element is measured by a voltage measuring circuit. The constant current also flows through a variable resistor element. The resistance value of the variable resistor element is adjusted so that a voltage generated in the variable resistor element corresponds to the voltage generated by the reference resistor element.

Abstract: A system and method for using a single test case to test each sector within multiple congruence classes is presented. A test case generator builds a test case for accessing each sector within a congruence class. Since a congruence class spans multiple congruence pages, the test case generator builds the test case over multiple congruence pages in order for the test case to test the entire congruence class. During design verification and validation, a test case executor modifies a congruence class identifier (e.g., patches a base register), which forces the test case to test a specific congruence class. By incrementing the congruence class identifier after each execution of the test case, the test case executor is able to test each congruence class in the cache using a single test case.

The process fluid pressure transmitter is also configured to provide an indication related to the at least one stored parameter.

Abstract: A method of extracting and analyzing a data set from a flow cytometer system of the preferred embodiment comprises the steps of (1) running a sample and saving all collected raw data, (2) viewing raw (or “unmodified”) data, (3) modifying the raw data (e.g., scaling and/or culling the raw data), (4) reviewing and saving the modified data, and (5) exporting the saved data. Once the sample has been run and all collected data have been saved, the user can repeat the steps of modifying the raw data, saving the modified data, and exporting the saved data as many times as necessary and/or desirable.

Abstract: A system for testing a fan interface on a motherboard is provided. A fan simulator receives a PWM signal from a fan interface of the motherboard, converts the PWM signal to a TACH signal and outputs the TACH signal to a computer via a fan connector. A difference between the actual rotation speed from the TACH signal and a preset desired rotation speed of the fan simulator is determined and analyzed by comparing the difference with a preset allowable error margin.

Abstract: A method of processing Fourier Transform Mass Spectrometry (FTMS) data includes performing a Fourier Transform of a part of a time domain transient and identifying from that transformed data signal peaks representative of the presence of ions. After peak identification, the full transient is then transformed, and the peaks identified in the partial transient transform are used to locate true peaks in the transformed full transient. The number of ‘false’ peaks resulting from random noise has been found to correlate to the resolution, so that using a partial transient to identify true peaks reduces the risk of false peaks being included; nevertheless this information can then be applied to the full data set when transformed. As an alternative, different parts of the full data set can be transformed and then correlated; because any noise will be random, false peaks should occur at different places in the two partial transforms.

Abstract: Provided herein is a method of determining the similarity between a first multivariate data set and a second multivariate data set. The method may be applied to rapidly assess the similarity between fluorescence spectroscopy multivariate data sets in quality control analysis. The method includes representing the data of a first and a second multivariate data set in matrix form to yield a multivariate data matrix and calculating the magnitude of an additive and subtractive combination of each multivariate data matrix. The concept of a penalty parameter is introduced to set a detectable limit of variance between the first multivariate data set and the second multivariate data set and the penalty parameter is used in combination with the magnitude of an additive and subtractive combination of each multivariate data matrix to determine a similarity value.

Abstract: Measurement data collected within a measurement frame of reference is fitted to geometric tolerance zones having regard for the uncertainties of the measurement.

Typically, the measurement data is multidimensional and the uncertainty zones have different sizes.

Abstract: A defect analyzer system having a program storage device storing instructions and an arithmetic unit executing the instructions. The system divides a defect analyzing region of a wafer into a plurality of grid squares and classifies the grid squares into a plurality of groups. The system then matches the defect information with the defect analyzing region. The defect information includes defect positions and sizes detected in the defect analyzing region. The system calculates a defect size distribution for each defect size in each of the groups, compares the defect size distribution and a predetermined estimation distribution for each of the groups, and calculates a difference. The system then compares the difference of each of the groups and a predetermined threshold value, extracts the group having the difference equal to or smaller than the predetermined threshold value, and outputs the defect information corresponding to the extracted group.

Abstract: A system and method for monitoring the power damping compliance of a power generation unit comprises a measurement unit that is configured to be coupled to a power generation unit to identify the voltage, current, and frequency values associated with power output therefrom. A processing system maintaining a model-based filter processes the voltage, current, and, frequency values to estimate the total amount of damping provided by the power generation unit. The estimated total damping is compared to prior historical values maintained in a database using various statistical techniques to determine if a power system stabilizer (PSS) provided by the power generation unit is being operated in a manner complying with predetermined guidelines.

Abstract: Various techniques are described for high resolution time measurement using a programmable device, such as an FPGA. The timing may be triggered by any event, depending on the applications of use. Once triggering has occurred, a START pulse begins propagating through the FPGA. The pulse is able to propagate through the FPGA in a staggered manner traversing multiple FPGA columns to maximize the amount of time delay that may be achieved while minimizing the overall array size, and thus minimizing the resource utilization, of the FPGA. The FPGA timing delay is calibrated by measuring for the linear and non-linear differences in delay time of each unit circuit forming the staggered delay line path for the timing circuit. The FPGA achieves nanosecond and sub-nanosecond time resolutions and is used in applications such as various time of flight systems.

Abstract: Disclosed are method and apparatus for registering multiple sensors collecting data from multiple objects. Sensor registration is decomposed into a two-step procedure. The first step corrects systematic errors. The second step assigns objects measured by one sensor to objects measured by a second sensor. Systematic errors are corrected by generating the global minimum of a systematic error function. One embodiment for generating the global minimum uses a Continuous Greedy Randomized Adaptive Search Procedure.

Abstract: A method for determining the accuracy of the estimated position for a target device in a wireless system includes the computation of a confidence index. In the online location determining phase, after knowing the observations of the radio signal for a target device, the target device's probability distribution of location and its motion model are combined to calculate the position uncertainty, thereby giving the confidence index of this location estimate. The invention determines the location probability distribution, and calculates the uncertainty of the location probability distribution and the possible maximum uncertainty under the current situation. Based on these uncertainties, this invention determines the confidence index of the radio signal. The confidence may be regarded as a quantity that the location uncertainty can be excluded in the location prediction.
