1. A life indicator for a component of a machine, the life indicator comprising:
- at least one sensor operably associated with the machine and configured to sense a property associated with the machine, the sensor being configured to output the sensed property as a data signal;
a memory element including a first data structure that determines a damage factor for the component of the machine based at least in part on the data signal received from the at least one sensor; and
a processor for executing the first data structure to determine the damage factor.

Abstract
A life indicator for a component of a machine is disclosed. The life indicator includes at least one sensor operably associated with the machine and configured to sense a property associated with the machine. The sensor is configured to output the sensed property as a data signal. The life indicator also includes a memory element having a first data structure that determines a damage factor for the component of the machine based at least in part on the data signal received from the at least one sensor. A processor executes the first data structure to determine the damage factor.
