Introduction

Edward Stehle is an inventor associated with Drexel University in Philadelphia, Pennsylvania. His patent work focuses on using computational geometry to identify and respond to software faults.

Latest Patents

Stehle is credited with 1 patent: “Detection, Diagnosis, and Mitigation of Software Faults.” The invention collects runtime measurements from a software application and uses them to define a geometric enclosure representing normal operating conditions. Measurements inside or on the enclosure’s perimeter indicate normal operation, while measurements outside it signal an anomaly or potential failure. In one embodiment, the enclosure is a convex hull in N-dimensional Euclidean space. Depending on the measurements, the system can take actions such as restarting the software or disabling access to a network port.

Career Highlights

Stehle’s patent illustrates an approach to software monitoring that models normal behavior mathematically and uses deviations from that model to guide fault response. His work is associated with Drexel University.
