Abstract:

A system for monitoring stress cycles includes memory storing a base value and an inflection value of a stress cycle and one or more processors coupled to the memory. The one or more processors are configured to receive a series of stress values from a stress sensor. For each stress value in the series of stress values, the one or more processors are configured to perform operations including performing a first comparison between the stress value and a previous stress value in the series of stress values, detecting an inflection in the series of stress values based on the first comparison, updating the base value and the inflection value in response to detecting the inflection, performing a second comparison between the stress value and the base value, determining whether the stress cycle is complete based on the second comparison, and recording the stress cycle in response to determining that the stress cycle is complete.
