Develop a system for moving large patients on the bed without risking injury to hospital staff.
The system had to fit a high power system into a very small footprint and still meet the thermal and power signal spacing requirements of UL 60601-1.
DornerWorks developed the electronic and software system which performed analog I/O, motor control, power regulation, and control of the device. A very high density board layout was needed to fit within limited space and this meant particular care needed to be used to meet the strict heat and EMI requirements dictated by UL 60601-1 in a high power design. Through the creative application of dual-use circuits and advanced motor control techniques, the system was designed, implemented, and met the regulatory directives.
