SENSOR SYSTEM AND METHOD OF COMMUNICATING DATA BETWEEN A DOWNHOLE DEVICE ON A REMOTE LOCATION
First Claim
1. A method of communicating data between a downhole device and a remote location comprising:
- generating a communication signal at the remote location by modifying a voltage amplitude of said signal; and
receiving said communication signal employing a variable threshold detection circuit in the downhole device, wherein said variable threshold detection facilitates dynamic determination of a threshold voltage under varying conditions.

Abstract
Disclosed herein is a sensor system having a sensor and at least one communication line operable with the sensor. The transmission medium is configured to convey data transmitted by the sensor to a remote location. The sensor transmits data on the communication line a plurality of times by at least two methods of transmission or modulation. Further disclosed herein is a method based on the foregoing. Further disclosed is a method of communicating by modifying a voltage amplitude of a signal and receiving the communication signal by employing a variable threshold detection circuit in the downhole device. Further disclosed is a system for communicating data between a downhole device and a remote location including a remote device for generating a communication signal, the remote device configured to modify a voltage amplitude of said communication signal.
