This timeline specifically focuses on the process surrounding Erna Schneider Hoover's most famous invention – the computerized telephone switching system – from conception to patent grant.
Problem Identification
Mid-1960s
Hoover identifies the problem of overload in electromechanical switching systems during peak usage times. These overloads resulted in dropped calls and inefficient network performance. She wanted to solve a crucial, real-world problem.
Invention and Development
1967
Hoover develops a computerized feedback system that monitors the load on the switching system and prioritizes tasks to prevent overload. Her algorithm allowed the system to dynamically allocate resources based on real-time demand.
Patent Application and Review
1967-1971
Hoover applies for a patent for her invention. The patent application undergoes a review process by the US Patent and Trademark Office.
US Patent 3,623,007 Granted
November 23, 1971
US Patent 3,623,007 is granted to Erna Schneider Hoover for her 'Feedback Control Monitor for Stored Program Data Processing System.' This patent recognized the novelty and utility of her invention.
Implementation and Impact
Post-1971
Hoover's invention is implemented in telephone switching systems, significantly improving network reliability and efficiency. Her technology helped modernize the telephone network and handle increasing call volumes.
