Abstract: An electrical power generator is characterized by a plurality of system parameters. The generator includes a controller for protecting the generator. The controller obtains data from which a present operating point of the generator and a power generating capacity of the generator can be determined. The controller further monitors data indicative of at least one system parameter as a function of time to detect an abnormality in a value of the system parameter. The controller then categorizes a type of event that caused the abnormality with respect to the data indicative of the system parameter as a function of time, the present operating point, and the power generating capacity. Finally, the controller provides a response for addressing the type of event that caused the abnormality.

Abstract: A simulation method includes the step of momently measuring a value of each of a strain, a strain speed, and a stress generated in the viscoelastic material, deriving time history data of a viscous drag, the strain speed and the stress, thereby deriving a relationship among the strain, the strain speed, and the viscous drag and setting the product as a product model whose performance is analyzed; inputting the relationship to the product model; and computing a stress and strain of a deviation component by using a deviation main strain and a deviation main strain speed converted from an entire coordinate system into a main strain coordinate system and a main strain speed coordinate system respectively to thereby conduct a simulation in consideration of a change of the viscous drag which occurs in dependence of a variation of the strain and the strain speed.

Abstract: Embodiments of the present invention generally provide a system and method for testing integrity of data transmitted to and from a target device through a data connection. In one embodiment, the method generally includes creating one or more test threads. The method further includes, for each test thread, generating a data load on the data connection by repetitively writing test data patterns to the target device and reading data patterns from the target device using a synchronous I/O dispatch method, measuring data throughput to and from the target device while generating the data load, comparing the data patterns read from the target device to the test data patterns to detect data corruptions. The method may further include generating debug information if a data corruption is detected by one of the test threads.

Abstract: Process for estimating the correlation matrix of signals of unknown characteristics in an array of N sensor. The process determines the correlation matrix {circumflex over (R)}s of the signals of known characteristics, estimates the correlation matrix {circumflex over (R)}x of the sensor signals, forms a matrix A equal to A={circumflex over (R)}s?1/2{circumflex over (R)}x {circumflex over (R)}s?1/2 and decomposes the matrix A into eigenelements, constructs a matrix B based on the eigenelements of the matrix A, and determines the estimated correlation matrix {circumflex over (R)}b of the interfering signals based on the estimated matrix {circumflex over (R)}s and of the matrix B, such that {circumflex over (R)}b={circumflex over (R)}s1/2 B {circumflex over (R)}s1/2. Such a process may find application to antenna processing.

Abstract: An eye diagram analyzer assigns a plurality of SUT data signals to be members of a labeled group of channels. There may be a plurality of such groups. In addition to mere superposition in an (X, Y) display space of the various i-many (X, Y)-valued pixels for individual component eye diagrams associated with that group, other measured data for those pixels within a group can be merged in various different modes to produce corresponding composite eye diagram presentations. E.g., in a Normalized Signal Density Mode the number of hits at each trial measurement point is summed over all channels in the group, and then divided by the total number of clock cycles measured for the ith measurement point in that group to produce a density Di associated with the corresponding ith pixel: (Xi, Yi, Di). If Di is rendered as a color or an intensity, the resulting eye diagram includes a representation (the Di) of a normalized density of transitions at each point (Xi, Yi), relative to that group as a whole.

Abstract: One embodiment of the present invention provides a system that facilitates measuring quality-of-service of a computer network server or collection of servers by determining the effect that transactions in one category of service have on transactions in other categories of service. The system operates by generating a varying pattern of synthetic transactions for one category of service and a fixed pattern of synthetic transactions for the other categories of service. The system sends the varying pattern and the fixed pattern of synthetic transactions and receives responses to these patterns across a network between the computer network servers and the synthetic transaction generator. The system measures the response time for the varying pattern of synthetic transactions and the response time for the fixed pattern of synthetic transactions. Additionally, the system calculates the effect of transactions in one category of service on response times in the other category of service.

Abstract: A system, method and computer program for facilitating the operation of a control system utilizing one or more input devices is disclosed. The control system provides the ability to monitor and modify operating parameters of the input devices. A function integrated within a software code is to be executed by the control system. The function is responsive to the input device. The input device includes at least one condition comprising a state wherein all of the conditions must be met prior to the execution of the function. A display of an unmet condition is exhibited to operator personnel of the control system during the execution of any function having an unmet condition prohibiting the execution of the function. The operator personnel is capable of overriding the unmet condition by selecting the state of the condition that allows the condition to be met, thus allowing the function to be executed. A maintenance log contains a record of the conditions that were bypassed or overridden.

Abstract: Techniques for finding sets of values that are relevant to attaining desired results, determining discrepancies between how different entities regard a set of values, and employing the discrepancies to determine how well individuals “fit” with other individuals or communities, how well communities fit with each other, how an entity's values compare with a desired set thereof, how an entity's values change over time, and what progress an entity is making towards acquiring value hierarchies that are useful in attaining the desired results. All of the techniques involve having entities assign values to hierarchies, with the value's position in the hierarchy being represented by a rating number upon which arithmetic operations may be performed. Discrepancies between value systems may be determined by comparing the rating numbers which the entities assign the values.
