Taking the place of up to four therapists, the prototype treadmill device is equipped with robotic knee braces that attach to a patient's legs. Sensors continuously monitor 24 distinct data elements, such as force, speed, resistance, and number of steps. These measurements help therapists evaluate progress and adjust the stepper device accordingly. The experimental device could enter clinical trials at UCLA within three years.

Fluorescent lights save energy and last longer but cast a greenish glow.
With the help of researchers at Brown University, engineers at Sandia National Laboratories in Albuquerque, NM, have come up with a brighter idea. Lightbulbs made from the chips could last up to 10 times longer than fluorescent bulbs and up to 50 times longer than incandescent ones.

Researchers at Dublin City University in Ireland have developed a diagnostic instrument that fits around a patient's wrist like a watch and produces results within 30 minutes. The data is then fed to a laptop computer for analysis.
