Abstract: A partial discharge monitoring apparatus for a rotating electric machine includes a partial discharge detecting circuit which measures each signal output from a partial discharge sensor located in the rotating electric machine simultaneously in a first frequency band and a second frequency band. Detection time for detecting each signal includes a peak hold time and a dead time, which comes after the peak hold time. A next-occurring signal is detected after the dead time has elapsed.

Abstract: A method for evaluating the aging level of a component includes measuring values of the elapsed time in operation of the component (tm,i), at least one entity (Im,i) indicative of the aging of the component, and the temperature (Tm,i) of the component, and processing the values measured as a function of a reference temperature (Tref) to produce corresponding normalized reference values (tref,i; Im,i) representative of virtual operation of the component at said reference temperature (Tref). An updated prediction model for the at least one entity over time is generated from the reference values (tref,i; Im,i). A predicted value (Ifit) for the at least one entity at a given time obtained by means of the prediction model is compared with an aging threshold. An aging warning signal is generated if the comparison indicates deviation of the predicted value (Ifit) beyond an acceptable range.

Abstract: A method of testing a computer system in a testing environment formed of a network of routers, servers, and firewalls. Performance of the computer system is monitored. A log is made of the monitored performance of the computer system. The computer system is subjected to hostile conditions until it no longer functions. The state of the computer system at failure point is recorded. The performance monitoring is done with substantially no interference with the testing environment. The performance monitoring includes monitoring, over a sampling period, of packet flow, hardware resource utilization, memory utilization, data access time, or thread count. A business method entails providing a testing environment formed of a network of network devices including routers, servers, and firewalls, while selling test time to a customer on one or more of the network devices during purchased tests that test the security of the customer's computer system.

Abstract: The present invention is directed to a method for analyzing the tail-end behavior of a lithium cell having a solid cathode. The tail of a longer-term accelerated discharge data (ADD) test is estimated from the tail of two shorter-term ADD tests. This is accomplished by first comparing the discharge tails of shorter-term ADD tests and determining angles or rotation that correspond to Rdc growth, and then trending rotation angles versus time to reach a give DoD. For example, the 18-month and 36-month ADD test tails are used to estimate the ADD test tail of a similarly constructed cell subjected to a longer-term ADD test, for example a 48-month ADD test.
