Kim Rubin was the technical visionary behind GreenSpring Computers. In the late 1980s, Kim led the technical direction at GreenSpring Computers, where he designed a modular I/O concept that would become the IndustryPack® (IP) standard.

Kim’s work laid the groundwork for formal standardization. In 1994, the VITA Standards Organization (VSO) formed VITA 4, a committee to validate and clarify the IP Module specification. The result was ANSI/VITA 4-1995, which remains a recognized standard for modular I/O in embedded computing. VITA 4 was the first non-VMEbus standard to be developed under the VSO.

This innovation addressed a growing need for granular, low-cost I/O expansion in embedded systems, and by 1994, over 80 companies were building products to the IP standard. His foresight helped shift the industry from proprietary daughterboards to interoperable, open standards, enabling broader adoption and innovation.

Kim currently works as a registered patent agent, helping startups and midsized companies develop intellectual property strategies, working on technologies related to autonomous vehicles, vehicle-to-vehicle (V2V) communication, and consumer electronics. He is also the founder of Elephant Timer, a rugged, simplified timing device.

Kim Rubin holds over 30 patents spanning fields including networking, image processing, autonomous systems, and wearable tech.
