Title:
RECONFIGURABLE SENSOR SIGNAL DEMODULATION SYSTEM
Document Type and Number:
WIPO Patent Application WO2005022087
Kind Code:
A3
Abstract:
A reconfigurable position detection system demodulates an LVDT sensor via software in a microprocessor instead of hardware. The LVDT output is sampled and undergoes a root mean square calculation or an averaging calculation to obtain an LVDT position value. The lack of hardware demodulation circuitry allows the system to be reconfigured to accept sensors other than LVDT sensors by modifying the software in the microprocessor, without requiring any changes to hardware components in the system.
