An apparatus and method for sensor signal prediction and for improving sensor signal response time, is disclosed. An adaptive filter or an artificial neural network is utilized to provide predictive sensor signal output and is further used to reduce sensor response time delay.

A simulation test bench environment for testing a circuit is described. The test bench environment uses high-level task routines executed by one or more bus functional device models to generate input test vectors. A timing and protocol checker verifies both signal timing and functional operation bus specifications. Data and parity miscompares and corruptions are reported in real-time during simulation. An error and interrupt handler services errors and interrupts by communicating with the buses ...

A method of analyzing an electromagnetic interference amount of an LSI includes an equivalent impedance information calculating step of calculating and estimating equivalent impedance information based on circuit information of an LSI chip and package information of the LSI chip, and an electromagnetic interference noise calculating step of calculating an electromagnetic interference noise based on the equivalent impedance information.

A method for error detection and error correction in the monitoring of measurement values is disclosed, in which the value to be tested is checked for plausibility in an evaluation device, for example a computer, and in the event that an implausibility is identified, the existence of an error is determined. If a further check finds that the error no longer exists, then an error correction takes place. A prerequisite for the error correction, however, is that the range of the value to be monitore...

The directional element, following enablement under selected input current conditions, calculates a zero sequence impedance, in response to values of zero sequence voltage and zero sequence current. The current value is selected between two possible values, one being the value from an associated current transformer, the other being the sum of the currents I.sub.A +I.sub.B +I.sub.C. The calculated zero sequence impedance is then compared against sensitive selected threshold values, established pa...
