A new air-powered computer detects failures in medical devices using air pressure, eliminating electronic sensors for a safer, cheaper alternative. Future plans include expanding its use to hazardous environments.
“IPC devices can save lives, but all the electronics in them make them expensive. So, we wanted to develop a pneumatic device that gets rid of some of the electronics, to make these devices cheaper and safer,” said William Grover, associate professor of bioengineering at UC Riverside and corresponding paper author.Pneumatics move compressed air from place to place. Emergency brakes on freight trains operate this way, as do bicycle pumps, tire pressure gauges, respirators, and IPC devices.
If it does blow, that’s a sign the machine requires repairs. In a video demonstrating the air computer, Grover and his students are shown damaging an IPC device with a knife, rendering it unusable. Seconds later, the whistle blows. Tall buildings full of corn or wheat, grain silos are a common sight in the Midwest. Often, a human has to go inside with a shovel to break up the grains and even out the piles inside.
