Ajay Bhatt: Intel's Rock-Star Inventor
"When we started . . . we found the cheapest connector that we could afford at that point, and that's what we've ended up living with," says USB inventor Ajay Bhatt.

IEEE Spectrum's Steven Cherry recently interviewed Intel engineer Ajay Bhatt, who invented the universal serial bus (USB) port about 25 years ago. Bhatt went on to develop USB 2.0 and 3.0, and to work on the Accelerated Graphics Port, PCI Express, and Intel's desktop power-management architecture. Bhatt currently is analyzing PC architecture to provide portable computers with the power efficiency required to last all day.
Over the past four years, Bhatt has "audited each part of the architecture and systematically gone in and tried to fix the issues in the system that would result in draining the power unnecessarily," he says. The goal is to adjust power consumption based on a user's tasks so that highly demanding applications receive the required level of processing power, while simpler tasks such as word processing are more power efficient. Interoperability is a consideration, because computers include parts from a variety of vendors, which must agree on a common set of power privileges.
Bhatt says Intel is highly successful at bringing research and development ideas to market because of its investment in Intel Labs, partnerships with academia, and long-term view of technologies that will be needed in the future.
