Title: The Innovative Contributions of Roger Finch

Introduction

Roger Finch is a notable inventor based in Ipswich, MA (US). He has made significant contributions to the field of technology, particularly in data acquisition systems. With a total of 3 patents to his name, Finch has demonstrated a commitment to innovation and problem-solving.

Latest Patents

One of Finch's latest patents is for a Continuous Self-Calibrating Data Acquisition System. This system compensates for performance differences in a set of information channels by modeling each channel as linear and characterizing it with an offset and a gain. The system includes memory for storing the offsets and gains associated with the channels, along with means for mathematically adjusting the output of each channel. Additionally, it features filters that reduce the effect of random noise on measurements by generating signals representative of time-weighted averages of the offsets and gains.

Another significant invention by Finch is an Apparatus for and Method of Autozeroing the Input of a Charge-to-Voltage Converter. This invention is an autozero compensator designed for processing low-level signals. It comprises an input integrating operational amplifier that provides an error signal in response to offset voltage across its differential input terminals. A second amplifier in a feedback loop generates a charge at a compensating voltage equal and opposite to the offset voltage, which is then applied to the input amplifier to cancel the offset voltage.
