A FIT value for a micro-processor
A FIT\footnote{Failure rates measured per $10^9$ hours of operation
are known as Failure in Time (FIT) values.} value for a micro-processor
may be determined at around 100 using these documents for instance, but
FIT claims for modern integrated micro-controllers are typically less than five~\cite{microchipreliability}.

Detection periods are typically determined for the process under control. For instance, for a flame detector in an industrial burner this

Work has been performed using component failure statistics to
offer the more likely multiple failures~\cite{FMEAmultiple653556} for analysis.
