Abstract: Systems and methods configured to guide and manage laboratory analytical process control operations. A Biometric quality control (QC) process application is configured to monitor bias and imprecision for each test, characterize patient population data distributions and compare, contrast, and correlate changes in patient data distributions to any change in QC data populations. The Biometric QC process monitors the analytical process using data collected from repetitive testing of quality control materials and patient data (test results). The QC process identifies the optimal combination of, for example, frequency of QC testing, number of QCs tested, and QC rules applied in order to minimize the expected number of unacceptable patient results produced due to any out-of-control error condition that might occur.

Abstract: A method and apparatus for determining jitter and pulse width from clock signal comparisons provides a low cost and production-integrable mechanism for measuring a clock signal with a reference clock, both of unknown frequency. The measured clock signal is sampled at transitions of a reference clock and the sampled values are collected in a histogram according to a folding of the samples around a timebase which is either swept to detect a minimum jitter for the folded data or is obtained from direct frequency analysis for the sample set. The histogram for the correct estimated period is statistically analyzed to yield the pulse width, which is the difference between the peaks of the probability density function and jitter, which corresponds to width of the density function peaks. Frequency drift is corrected by adjusting the timebase used to fold the data across the sample set.

Abstract: This invention allows personnel located on two different structures, such as two ships, to continually monitor the separation distance between the two structures, with all of the necessary equipment being located on only one of the structures. This is accomplished using a laser range finder, or other range sensor, to continually measure separation distance and send it electronically to various displays. The displays are positioned and sized such that all involved personnel can view the continually updating separation distances. The invention incorporates displays large enough to be viewed ship-to-ship in direct sunlight, in addition to smaller displays. The displays are dimmable or backlit for night viewing and include a safety feature that turns them off when communication is lost with any range sensor. A strobe on the display helps personnel find where the display has been positioned, such as on a ships gunwale or hand railing.

Abstract: The present invention relates to a method for location of a fault utilizing unsynchronized measurements of three phase voltages and currents acquired at the line terminals without synchronization. Phasors for symmetrical components of the measured quantities are determined and used in the fault location algorithm. According to one embodiment, positive sequence phasors of post-fault quantities are used for estimation of the distance to fault and it is distinctive that such an estimation of a distance to fault is performed without essentially involving iterative techniques. In this embodiment, the fault location algorithm step is performed regardless of the fault type. In later steps, the type of fault may be obtained. According to another embodiment of the invention, at the occurrence of a fault, the type of fault is determined. If it is determined that it is not a three-phase balanced fault, negative sequence phasors are used for the estimation of the distance to fault.

Abstract: The computerized method for data analysis is a computerized method for identifying a causal relationship between at least one independent variable and a dependent variable in a set of data representing historical operating parameters of an industrial process. Data representing historical operating parameters of an industrial process is input into a computer system. A dependent variable and at least one independent variable are identified. A plurality of data sampling periods, such as days of operation, are identified for organization of the data. Dependent and independent variable data are collected from the historical data for each of the data sampling periods. Data sampling periods are ordered, according to the independent variable data, into distribution sets. Once the distribution sets have been arranged, average values are calculated for the dependent and independent variable data, and then graphed to relate the dependent variable data to the independent variable data.
