James Newton Says:
The head mouse: From the back of the eyeglasses, a line runs between the two ends of the frame (just like the the straps designed to allow glasses to hang down from the neck, but thinner) and a pully and line from that one is pulled down the back by a weak spring. Left / right motion of the head will not pull on this line, because the line between the frames will simply pull through the pully. Front / back motion of the head will pull the line.
Another line goes down the back from only one of the two ends of the frame. This line will be affected more by the left right motion than the up down motion.
Both lines are passed around the shaft of the encoders on a mechanical mouse before being terminated in a long, weak spring or a "take up" reel.
Regenerative Bike Brake: Use a flexible or hinged frame to store power from breaking by bending or raiseing the frame. When the break is released, the frame returns to its original shape or position and in doing so starts the bike off again.
