I’ve invented a hardware module related to power management and fault tolerance for Linux-based single board computer deployments.
I have filed a provisional patent (application #63/993,024) and have completed validation testing across multiple SBC platforms (Pi 1B, Pi Zero, Pi 3B and Pi 5).
The device acts as an external supervisory controller designed to protect SBC systems from power faults and operating system crashes while enabling reliable remote and scheduled power control.
Key capabilities include:
• brownout detection with graceful OS shutdown
• watchdog / heartbeat monitoring with automatic power recovery
• remote graceful shutdown via IR or external button
• scheduled power control (one-time or recurring)
• elimination of parasitic power draw when systems are off
• optional real-time clock service for network-isolated deployments
The design allows these capabilities to be added to existing deployments (Raspberry Pi, industrial SBCs, etc.) without modifying the host hardware or enclosure.
I’m reaching out because I believe this concept may be relevant to companies working in embedded systems or industrial/consumer/educational SBC solutions. My goal is to explore whether it might be of interest for acquisition or further development.
If this sounds relevant, I’d be happy to provide a short technical overview. I can also share additional details under NDA if helpful.
Thank you for your time.
Best regards,
Jerry Firebaugh
