Despite what various spy movies may have us believe, sending people into buildings' ductwork isn't a good idea. That said, those ducts do need to be cleaned periodically, otherwise the human inhabitants of the buildings can develop serious respiratory problems. Robots have been designed to do the job, although they've generally been wheeled or tracked devices that can only move horizontally. Now, however, scientists at UC San Diego's Jacob's School of Engineering have created DucTT – a highly-efficient robot that can climb up ducts, and run for up to six hours on one charge of its battery pack.
We've already heard about an electronics-packing mouthguard that can be used to detect serious impacts to the head.
Now, scientists at the University of California, San Diego have
developed one that could provide continuous readings of users' health
markers including lactate, cortisol and uric acid. It may be used to
monitor the well-being of people such as diabetics, to track the
performance of athletes, or to detect stress in soldiers.
Researchers from the University of California, San Diego (UCSD) are taking inspiration from nature in the search for new materials that could one day be used to create body armor. The study, supported by the US Air Force, focuses on the unique structure and strength of the hexagonally-scaled shell of the boxfish.
It's important to know how much pain young hospital patients are
experiencing, and not just because no one wants them to suffer –
additionally, excessive pain can indicate problems that need addressing.
That's why scientists at the University of California, San Diego School
of Medicine have developed facial pattern recognition software that
objectively assesses children's pain levels based on consistent
