"Now, hams in New England are helping the University of Massachusetts at Amherst improve the flexibility of ventilators already in use by BayState Health. Those ventilators used short control cables and ran on D-cell batteries that needed to be replaced every 48 hours."
"Engineers from UMass Amherst responded to a request from Baystate Health in Springfield for help in fighting the COVID-19 pandemic by designing new, longer control cables for ventilators and the elimination of battery power sources."
"The UMass team solved the problem using a commercial off-the-shelf battery eliminator. They ordered a suitable battery eliminator and successfully tested it on a portable ventilator at Baystate. Subsequently, Baystate ordered 50 of these power supplies directly from The Battery Eliminator Store."
