USB port connectible Device Reminder

Chih-Cheng Kuo , United States

This design helps users of USB devices if an USB device is left behind after usage.

I am a computer software, firmware and systems engineer for thirty years. I also got two master degrees of electrical engineering and computer science. I always like to think a better way or better design to do thing since I was a little kid.

I invented "Secure Open Smart Card Architecture" in 1997, which was granted U.S. patent 5754762 and 6003134. This design added a security co-processor into a smart card chip to provide programmable and multiple application co-exist smart card chip design.

I also invented "USB port connectible device reminder" (U.S. patent 7741974), which provides immediate warning message if a USB device is left behind after usage. This design is very useful for professionals who have to use USB drive in multiple places like medical doctors in a hospital, engineers moving around in different labs. and people who use USB drives in public library or Internet cafe.
