We then ran into the Freescale folks (who, we suspect are behind the Samsung demo) showing off an engineering prototype of the Belkin CableFree Hub in the Belkin booth.

Ok, then what about the code that enables video call support in OS 3.2 or that protected engineering prototype we saw just one day before launch showing a cutout at precisely the same spot so as to not obscure whatever was underneath?

There's still a chance we're looking at an elaborate KIRF or an early engineering prototype that could change, but given that 9to5 Mac just got very similar images with black trim, there's a real possibility that we've just been given a sneak peek of what to expect from Apple later this year.

While many offer leg support, a team from University of Pennsylvania recently took silver in an engineering competition for its TitanArm prototype, a powered upper-body exoskeleton that, as the picture above shows, allows you to out-rep anyone at the gym.

The Robotics and Mechanisms Laboratory (AKA the RoMeLa Project) at the College of Engineering at Virginia Tech has designed and built a prototype robotic hand that is controlled and operated by compressed air.
