Abstract: A system and method for use in signal measurement systems that acquire and store signal data in accordance with a trigger specification. The present invention stores and displays operator-generated annotations with each trigger branch of a trigger specification. The annotations, referred to herein as trigger branch comments, can provide meaningful information about, for example, the trigger branch condition, occurrence specification or resulting action, as well as any other aspect of the trigger specification. The branch comments are stored with the associated trigger branch as part of the instrument configuration, and are automatically restored when the configuration data is loaded into the instrument, and printed with the associated trigger branch. The display of the trigger branch comments for each trigger branch may be controlled individually or collectively to enable the operator to configure the display of the trigger specification as needed.

Abstract: A method for the testing of electronic components, proposing an optimization of a duration for the tests of this method, includes the step of choosing an earliest possible measurement date (Dm) with respect to an initial testing date (Do). According to this method, this earliest possible measurement date is chosen by considering statistical images (IS) obtained on a population of components (P1, P2) and by comparing these statistical images with one another by means of a criterion. This criterion takes into account a mean and a range of the responses given by the test population during iterations of a same test with different measurement dates.

Abstract: A method and apparatus are disclosed for simulating planar waveguides having a rectangular cross-section using a beam propagation method and design tool based on the FFT-BPM. Constraining the beam propagation method to planar waveguides having rectangular cross-sections significantly reduces the computational complexity and increases accuracy. The beam propagation method can be performed entirely in the angular spectrum domain. The constrained shape of the waveguide allows the structure to be accurately specified by its width and center-to-center arm spacing, thereby avoiding transverse spatial quantization.

Abstract: A method for in-service RAM testing in computer systems and networks having a virtual memory. The method involves identifying a number n of physical memory units pi, i=1 . . . n, in the RAM and a number n−1 of virtual memory units vj, j=1 . . . n−1, in the virtual memory, performing a one-to-one mapping to map the physical memory units pi to virtual memory units vj such that a physical memory unit px is left unmapped, and then testing data in the unmapped physical memory unit px by destructive or non-destructive tests. After the test data from another physical memory unit py is copied to physical memory unit px and a one-to-one re-mapping of physical memory units pi to virtual memory units vj is performed such that physical memory unit py is left unmapped. The data in physical memory unit py is then tested and the steps of copying, one-to-one re-mapping and testing can be repeated until all physical memory units pi are tested.

A failure time is modeled based on the individual component failure rates associated with individual components of the integrated component. Individual component maintenance times are retrieved associated with individual components of the integrated component. A maintenance time is modeled based on the individual component maintenance times associated with individual components of the integrated component. A reliability assessment is determined based on the interconnectivity of components of the power system, the modeled maintenance times, and the modeled failure times.

Abstract: A Traffic Safety prediction Computer Program (TRAF-SAFE) and sub-models for predicting the number of accidents, injuries and fatalities expected annually at an intersection or series of intersections based on the particular intersection and roadway features. A finite analysis approach to an intersection is used to break the intersection into discrete elements such as lanes, turnbays, stop control signals, and traffic flow rates. The total annual expected accidents can then be calculated as a summation of the interrelation of the individual elements. A Poisson's distribution is used to statistically estimate the likelihood of the individual vehicles occurring within a discrete time frame being investigated. The conflict probabilities between various permutations of the traffic flow is then calculated and summed to determine the number of conflicts for the intersection or roadway.

Abstract: A reference clock is inputted into a target IC from a reference clock generator, and an output signal whose frequency is minutely deviated is converted into binary digital output data by a digitizer to be stored in an area A of memory. A computing unit generates digital data having the same period as a reference clock to store the digital data in an area B of the memory. Ternary numeric data is obtained by subtracting data in the area B from data in the area A of the memory to be stored in an area C of the memory. Data in the area C is added to the numeric data every fixed time and is stored in an area D of the memory. An amplitude of a waveform of this data is proportional to the deviation amount of a frequency, and, a period thereof corresponds to one period of deviation amount of a frequency. It is possible to easily implement a test for a deviation amount and a period of a frequency by obtaining the relation between the amplitude and deviation amount beforehand.

Abstract: Programming a reference voltage in a reference cell of a charge-based memory to a level that will maximize the predicted operational life of the memory, based on the application-specific predicted usage profile of the memory and the effects of that usage profile on the leakage curves of the various memory states. The different states of a memory cell may have different leakage rates, based on operational and environmental considerations, causing the cell to fail prematurely in one state, while having significant remaining life in the other state(s). The operational life of the memory can be increased by adjusting the reference threshold voltage so that the faster-leaking sate will last longer before failure occurs. Maximum operational life can be achieved by setting the reference voltage to maximize the predicted time-to-failure of the state with the shortest predicted time-to-failure.

Abstract: An analysis scheduler for scheduling the automatic processing of performance data through a plurality of analysis tools is disclosed. Performance data provided to some of the tools by the analysis scheduler may be specified to be within a predetermined (but variable) look-back period. The analysis tools identify faults and anomalous conditions and also create repair recommendations, and automatically create problem cases when conditions warrant, or update existing problem cases with additional data, all under control of the analysis scheduler. The problem cases are reviewed by a human user and then forwarded to the railroad for implementation.

Abstract: A network management node monitors network attributes of a network. The network management node is connected to network devices through the network and receives data values associated with measured network attributes from said network devices. The data values are stored in the network management node and a baseline value and rearm baseline value for a network attribute are calculated from a plurality of the received data values measured during a first period of time (e.g., a first time bucket). These data values are compared to the baseline value, and an alarm is generated in response to at least one of these data values exceeding the baseline value. The alarm is reset if at least one subsequently measured data value is below the rearm baseline value. The baseline value and rearm baseline value are recalculated from received data values measured during subsequent time buckets. Data values measured during the subsequent time buckets are compared to corresponding baseline and rearm baseline values.

The systems of the present invention provide indicators to evaluate the integrity of the test elements and a verification device to evaluate the performance of the analyzer. Such systems may be provided as kits with instructions for use.

Abstract: The present invention provides a magnetic field measuring method and system for determining the magnetic field of an integrated circuit (IC) inside the IC package, including the pre-packaged IC. In one embodiment, induced voltages due only to the magnetic field are determined at measurement heights on the order of the line spacings in an integrated circuit. A magnetic probe is used; the probe has a loop of wire parallel to the current, for measuring the induced voltage of the horizontal component of the magnetic field. The induced voltage due to the electric field is removed by using a calculation including the difference of two measurements. The magnetic field distribution for the integrated circuit may be determined by using the above procedure on a grid like pattern above the IC.

Abstract: An apparatus for signal amplitude restoration has a received signal input and a scaled received signal output. An amplitude correction factor generator has an estimated signal-to-noise power ratio input and a received signal input. A variable gain amplifier uses the correction factor generator output to control its gain, and amplifies or attenuates the received signal input to provide the scaled received signal output. An average SNR estimator uses the amplifier output as its input, and provides an output connected to the estimated signal-to-noise power ratio input. The apparatus processes received signals in an iterative fashion, such that at least one of the outputs is stored for use as a feedback input during later iterations.
