Really Embedded System

A professor at the University of Reading (United Kingdom) claims to have
become the first person to have a microprocessor surgically implanted in his
body. Kevin Warwick, chairman of the university's Cybernetics Department, had
a glass capsule, about 23 by 3 millimeters in size inserted into his arm.
Warwick reportedly demonstrated the experiment by walking through
audio-enabled doorways which, after communicating with thw implanted
controller, told him how many e-mail messages he had. Upon his doctor's
recommendation, Warwick removed the implant after 10 days. To prevent
infection, he also took antibiotics.
