Scanner Diagnostics Utilizing Three Axis Accelerometers
First Claim
1. A diagnostic system for monitoring a scanning system that detects characteristics of a sheet of material during linear translation along a translation axis of a bi-directionally driven mobile detector device, the diagnostic system comprising:
- (a) the scanning system being monitored which comprises;
(i) a first elongated member that extends along a first direction wherein the first elongated member supports a first carriage that is mounted thereon; and
(ii) means for driving the first mounted carriage, that supports a first sensor head, along a main scanning direction;
(b) a vibration sensor configured to measure vibrations generated by one or more components of the scanning system and generating vibration signals indicative of operation conditions of the one or more components; and
(c) means for correlating the vibration signals to modes of operations of the one or more components of the scanning system.

Abstract
Numerous failure modes, causes, and adverse operating conditions on scanner systems exhibit mechanical signatures that are detected by three-axis accelerometers located in the upper and lower sensor heads. A diagnostic system for monitoring the scanning system that detects characteristics of sheet materials during linear translation along a translation axis of a bi-directionally driven mobile detector device includes a vibration sensor configured to measure vibrations generated by various components of the scanning system and to generate vibration signals indicative of operation conditions of the components. Correlating the vibration signals to modes of operations of the components identifies the source, location and severity of potential problems in the scanner. In dual scanning systems, the accelerometer in the upper scanner head monitors activities associated with movement of the upper carriage while the accelerometer in the lower scanner head monitors activities associated with movement of the lower carriage.
