Real time data processing and display system for non-linear transducers
First Claim
1. A real time system for providing a visual indication of a physical variable measured by a non-linear transducer, said physical variable being a known function of a time related characteristic of the signal at the output of said transducer, comprising:
- interval counter means receiving the output of said transducer, periodically measuring the time related characteristic of said transducer output, and generating a counter output signal indicative of said time related characteristic for each measurement;
processing means receiving said counter output signal for each measurement, calculating the value of said physical variable corresponding to said time related characteristic according to said known function, and providing an output signal indicative of said physical variable; and
output means receiving the output of said processing means and providing an indication of said physical variable for each measurement.

Abstract
A system for linearizing, processing and displaying data received from a non-linear transducer. The system includes a keyboard for entering coefficients which characterize the transducer to adjust the system so that it matches the physical parameters of the transducer. The linearized data may then be processed to generate selected functions of one or more transducers before being displayed on a digital display. The system processes data in real time so that the displayed data is frequently updated. Self-monitoring circuits detect processing or operating errors in the system and generate an appropriate error indication. The system further includes means for preventing the loss of data from volatile memories in the system, as well as means for initializing the central processing unit to the first program instruction when power is removed from the system.
