Title: The Innovative Contributions of Joel L. Hoffner
Introduction
Joel L. Hoffner is a notable inventor based in Johnstown, PA, who has made significant contributions to the field of electro-optical systems. With a total of five patents to his name, Hoffner has developed advanced technologies that enhance the measurement and analysis of hot bars in industrial applications.
Latest Patents
Hoffner's latest patents include a "Bar gauge plotting and display system" and a "Linearity correction system for electro-optical gage." The bar gauge system is a computerized electro-optical system that gauges two orthogonal dimensions of a moving hot bar and plots the cold bar profile. It utilizes dual back-lighted electronic camera heads mounted 90 degrees apart to generate separate bar shadow pulses, which represent the orthogonal dimensions of the bar. The system processes these pulses through individual camera electronics, correcting for various optical and electronic errors. The data is then used to plot deviations from the aim size of the cold bar profile, with outputs available on CRT and printing terminals.
The linearity correction system also employs a computerized electro-optical approach to gauge the dimensions of a moving hot bar. It generates high-speed bar shadow pulses that are processed by camera electronics and a digital computer. This system is designed to compensate for field-of-view errors and other nonlinearities, ensuring accurate measurements of bar size and position.
