Abstract: A transient or voltage stability transfer limit is calculated for a power network having at least two independent AC generators supplying a common load via separate AC transmission lines having at least one bus. Steady state values for variable characteristic electrical parameters of variable elements of the network are determined based on particular values for power transferred by the transmission lines. Static values for passive characteristic electrical parameters of passive conductive elements of the network are determined. A contingency resulting in a sudden change of at least one of the variable electrical parameters and the passive electrical parameters is selected. A post contingency steady state value for a voltage at one of the buses is calculated.

Abstract: A tester for multiple types of radios has a first group of generic test elements common to all types of radios to be tested and second groups of test elements specific to each one of the multiple types of radios. Each of the second groups of test elements is mounted within a pluggable module for insertion into the tester where it couples to a common bus accessed by all of the other test elements and by the controlling computer. Each pluggable module contains a specific identifier which, when accessed by the controlling computer initiates a stored program which causes the computer, via the bus, to couple the various test elements into a configuration required to test the radio type associated with that identifier. The system is very compact and conveniently uses a lap top computer as the controlling element.

Abstract: The transmission path (4) is fed with a test signal (M'), which is generated from a sequence (m) of spectral components (S1 . . . S10), which are distributed equidistantly in the frequency domain, as the result of combining with an additional function (ZSF). The additional function (ZSF) is selected so as to allow the test signal (M') to contain, besides the spectral components (S1 . . . S10)of the sequence (m), additional spectral components (ZS1 . . . ZS21). An output signal (M") received on the output side of the path is evaluated at evaluation frequencies (AW1 . . . AW10), in the case of which the test signal (M') is free per se of spectral components and, in the case of which, the test signal (M'), after a self-convolution, exhibits additional spectral components (SA1 . . . SA10). The additional spectral components (SA1 . . . SA10) occurring at the evaluation frequencies (AW 1 . . . AW 10) allow a non-linearity of the transmission path (4) to be immediately detected.

Abstract: The invention relates to a method for determining quantities which characterize driving behavior. Signals indicative of steering angle, longitudinal speed of the vehicle, and two transverse accelerations located one behind the other in the longitudinal direction of the vehicle, are fed to a computing device.

Furthermore, at least one of the further quantities is the sideslip angle or the yaw-angle velocity which are determined and output by the computing device.

Abstract: A method and system are disclosed for the automated alignment of free-form geometries. The method includes the steps of providing a computer work station, a first HDPDM describing the first geometry, and a second HDPDM describing the second geometry. The two geometries must be in crude alignment with one another within a coordinate frame. Next, a plurality of normal distances are computed from the first geometry to the second geometry. The normal distances are used to derive a weighted-fit objective function. A step size is then determined, and the step size is used in the following step of iteratively translating the second HDPDM until the objective function is maximized. The steps of determining a step size and iteratively translating the second HDPDM are repeated until the step size is less than or equal to a desired alignment resolution. The disclosed system includes the means for turning out the steps of the disclosed method.

Abstract: A method and system achieving the results of a conventional titration without the need to chemically dilute a sample. Such a result is accomplished by providing a plurality of calibration standards, each containing a different known concentration of a visualizable material. The visualizable material contained within each calibration standard is then visualized (the parameters of the visualization forming a setting). The visualization is then altered by adjusting at least one parameter of the visualization until the point where the visualizable material within each calibration standard can no longer be visualized within the solution. The visualizable material within a sample solution having an Unknown concentration of the visualizable material is then visualized using settings corresponding to the plurality of calibration standards to generate a number of modified visualizations. (Each modified visualization corresponds to the concentration of the standard to which it relates).

Abstract: An integrated circuit device for comparing the state of a large number of inputs (i.e. "discretes") against any one of a plurality of selectable voltage levels. The compared data is examined in a 3.times.3 matrix format. In a redundant mode, comparators are utilized in a triple-redundant configuration to obtain a consensus on input states, at three successive time intervals, raising a flag when consensus fails. Inputs, whether in a redundant or non-redundant mode are distributed along three different sides of a rectangular-shaped substrate to prevent catastrophic mechanical failures. In the redundant mode, discretes are compared using a voting technique such that when all three levels are the same, an error free status is provided, whereas a two-out-of-three vote is interpreted as correct but with an indication that the discrete being monitored requires further checking.

Abstract: An apparatus and method for analyzing the cell objects of a cell sample for the diagnosis and treatment of actual or suspected cancer is disclosed. An image of the cell sample is first digitized and morphological attributes, including area and DNA mass of the cell objects are automatically measured from the digitized image. The measured attributes are compared to ranges of attribute values which are preestablished to select particular cell objects having value in cancer analysis. After the selection of cell objects, the image is displayed to an operator and indicia of selection is displayed with each selected cell object. The operator then reviews the automatically selected cell objects, with the benefit of the measured cell object attribute values and accepts or changes the automatic selection of cell objects.

By means of a measured value or data determination dependent on the position of the fixed minimum and maximum values, it is ensured that an effective noise averaging and a reliable detection of narrow pulses are made possible.

Abstract: An apparatus and method for adaptively updating the drive signal in a shock testing system so as to produce a desired response signal. The updates to the drive signal are based on measurements of the system's actual response signal and closed loop updates to the test system's transfer function. An initial estimate of the test system transfer function is obtained by using a calibration signal as the drive signal and measuring the response signal. An initial estimate of the actual drive signal is then obtained based on the desired response signal and the initial estimate of the transfer function. The initial estimate of the drive signal is then applied to the test system, and the actual response signal is measured. The present invention then adaptively updates the test system transfer function.
