For the man who was mainly responsible for the invention of the USB (Universal Serial Bus), The stimulus came from his wife and child. Needing to print out their daughter's school project, His wife used to ring up chief architect Ajay Bhatt in his lab at Intel's Oregon (US) plant, asking for help to connect the pc and printer properly. It was not easy- with different printers needing different ports. Bhatt wondered: why not create a single solution to replace serial, parallel and printer ports on a PC?
In November 1995, His work which own him 8 patents, resulted in the USB 1.0 standard for connectors. Intel and Bhatt jointly decide to make the standard available free of all licensing and royalty fees. That was one reason why the USB became de factor standard for PC connections. It is also the reason Bhatt never made a paisa out of his invention. But he has no regrets. 
Bhatt has remained with Intel ever since. Currently Intel fellow and chief client platform architect for the PC client group, Bhatt wanted to be an architect-literally and even attended classes in the arts department of Baroda university, before deciding it was not for him and switched to engineering. (His father was a faculty member in the Arts Department of the university.)

Today he is deeply involved in refining the standards for type 'C'. He says he is most excited at the possibilities of USB connectors, both powering up devices and carrying data, since the standard allows for the connectors to carry nearly 100 watts of power.

Beyond the USB, His core work at Intel is on future client-computing platforms. Bhatt feels the day is not far, when PCs boot up and shut down in 2 seconds, as if operated by a light switch. And soon they will be powered wirelessly.

Ajay Bhatt dramatically simplified wired connections for all. But he will not be surprised, he told me, If eventually, most of what the USB does will be done wirelessly, rendering obsolete the universal wired connector he invented! since never stops!
