A method to perform an adaptive test performs a pressure sensitivity test to examine a pressure sensitivity of a solver to time, and judges, based on a result of the pressure sensitivity test, whether or not the pressure sensitivity of the solver is equal to or higher than a predetermined threshold. A second printed circuit board includes a second insulating board and a second conductive pattern. The abrasive article includes a monitoring element, such as a window, to allow transmission of radiation therethrough. The updating operations also can be programmatically scheduled by a client program of the updating operations. The invention allows for the substantially real-time detection and reporting of certain power grid events such as power plant trips.
