This is the product I have realized for the MDP company from Mladenovac, which produces medical equipment.
They hired me to design the electronics to control all the necessary functions of their intensive care bed.
That is the electronic device which controls five DC motors via a remote controller.
These motors are built into the special hospital intensive care bed. This enables adjusting the bed into different positions, for lying, sitting, special positions for examinations, by simply pressing the buttons on the remote controller.
This bed has won several prizes and gold medals in the world. It is also patented in several countries. Its patent number in the U.S. is: 4.847.929.
