Ultrasensitive surveillance of sensors and processes
First Claim
1. A method of monitoring a source of data for determining an operating condition of a selected system, comprising the steps of:
- providing reference data characteristic of an operating condition of a reference system;
collecting selected data from said source of data and which is characteristic of an operating condition of a selected system;
performing a bounded angle ratio test procedure on said reference data and said selected data to determine whether there is a deviation of said selected data for said selected system relative to said reference data of said reference system; and
generating an indication upon determining the deviation.

Abstract
A method and apparatus for monitoring a source of data for determining an operating state of a working system. The method includes determining a sensor (or source of data) arrangement associated with monitoring the source of data for a system, activating a method for performing a sequential probability ratio test if the data source includes a single data (sensor) source, activating a second method for performing a regression sequential possibility ratio testing procedure if the arrangement includes a pair of sensors (data sources) with signals which are linearly or non-linearly related; activating a third method for performing a bounded angle ratio test procedure if the sensor arrangement includes multiple sensors and utilizing at least one of the first, second and third methods to accumulate sensor signals and determining the operating state of the system.
