DETECTION AND QUANTIFICATION SYSTEM FOR MONITORING INSTRUMENTS
First Claim
1. A method of detecting real events using a detector that produces signal results at regular intervals, the method distinguishing the real events from noise or variation over time, comprising the steps of:
- obtaining a set of recent signal results representing the real events,calculating measures of the noise or variation based on said set of recent signal results,calculating an expected baseline value based on said set of recent signal results,determining sample deviation of said recent signal results,calculating an allowable deviation by multiplying said sample deviation by a threshold factor,setting an alarm threshold from said baseline value plus or minus said allowable deviation, anddetermining whether the signal results exceed said alarm threshold.

Abstract
A method of detecting real events by obtaining a set of recent signal results, calculating measures of the noise or variation based on the set of recent signal results, calculating an expected baseline value based on the set of recent signal results, determining sample deviation, calculating an allowable deviation by multiplying the sample deviation by a threshold factor, setting an alarm threshold from the baseline value plus or minus the allowable deviation, and determining whether the signal results exceed the alarm threshold.
