Abstract: An IC chip, a system and a method of operating the IC chip in response to an event trigger are provided. The method includes responsive to the event trigger, coupling a pin to a source of constant current to charge an external capacitor coupled to the pin and monitoring a capacitor voltage on the pin. If the magnitude of the capacitor voltage is greater than a rising threshold, detection of a falling threshold is enabled. If the magnitude of the capacitor voltage is greater than a voltage threshold, a first response is triggered and the pin is coupled to the lower rail to discharge the external capacitor. If detection of the falling threshold is enabled and the magnitude of the capacitor voltage is less than the falling threshold, the first response is also triggered.

Abstract: A method of treating a superalloy article, including selecting an article having a superalloy composition, whereby the article has a treatable feature on its surface. The method further includes removing a base alloy from a region abutting a first portion of the treatable feature. The method further includes treating a second portion of the treatable feature with a treatment composition to remove surface oxides. The method further includes inserting a treatment material into the first portion of the treatable feature followed by depositing the base alloy in the first portion of the treatable feature. The method further includes heat treating the article at a temperature above the melting point of the treatment material whereby the treatment material flows into the second portion of the treatable feature forming a treated article.
