1. In a performance monitoring system involving multiple sensors located at the monitored system, a method for reducing the bandwidth of the transmission of the sensor outputs to a listener, comprising the steps of:
- embedding a filter algorithm at the monitored system, the embedded algorithm defining predetermined thresholds for predetermined sensors and for outputting the fact of an exceedance of the associated threshold when such an exceedance occurs; and
,transmitting only the outputted fact of an exceedence to the listener utilizing a time division multiple access system, the outputted fact of an exceedence being transmitted time slot by time slot, whereby the bandwidth of the transmission of the data from the sensors is reduced due to transmitting only exceedances.

Abstract
In a system for monitoring multiple sensors, a technique is utilized to reduce the bandwidth necessary to transmit sensor data to a processing location by embedding a diagnostic and/or prognostic algorithm at the sensor location and providing that the algorithm outputs only values that are greater than predetermined exceedances for each of the sensors involved, and by monitoring only performance parameters that are critical to the monitored system.

9. Apparatus for use in a performance monitoring system that monitors performance of a monitored system, comprising:
-
multiple sensors for sensing parameters of a system; a controller including an embedded filter algorithm for defining predetermined thresholds for predetermined sensors and for determining when a predetermined threshold is exceeded, said controller outputting the fact of an exceedance when an exceedance of the predetermined threshold occurs; a transmitter coupled to said controller for transmitting the fact of an exceedance of the predetermined threshold to a listener, such that transmission to said listener is limited to only the transmitted fact of an exceedance. - View Dependent Claims (10, 11, 12, 13, 14)
