Title: Innovative Mind: The Patents of John L. Hagen
Introduction
John L. Hagen, an accomplished inventor based in Marion, IA, has made significant strides in the field of avionics and multi-core processing environments. With a total of 8 patents to his name, his contributions to technology are noteworthy and impactful.
Latest Patents
One of Hagen's latest patents pertains to a Product Line Avionics System Multi-Core Analysis Architecture. This invention introduces a multi-core processing environment (MCPE) that quantifies shared system resource access. It features several processing cores with multiple applications running on them, and utilizes virtual machines for accessing shared resources. Each core operates with core-specific shared memory and a guest operating system (GOS), efficiently writing timestamped VM data entries. The system includes a hypervisor that monitors performance and maintains data queues, helping to analyze execution times and resource access counts.
Another significant patent is the Multi-Core Optimized Warm-Start Loading Approach. This system optimizes the warm-start loading in a multi-core processing environment, particularly during power transient events. It manages to maintain stored data via a self-refresh mode, allowing for a quick startup process. Instead of copying an entire hypervisor image to system memory, the boot loader selectively transfers only modifiable portions, thus significantly speeding up the warm-start sequence.
