DRX technology

CLOSED LOOP WITH FEEDBACK

The entire line of DRX products has a closed loop with feedback, which is defined as an automatic control system that is able to adjust the calculated decompression force values ​​by itself and compare them with reality. A closed system feedback loop improves overall system performance.

The efficiency of the closed loop feedback system varies with the variables.

With respect to the spinal decompression system, the measured quantity is most often the force - the tension used to stretch the vertebrae.

HIGH SPEED CLOSED LOOP WITH FEEDBACK

• Sophisticated servo motion control

• Custom dynamometer and eclectronic feedback

• Windows / PC-based therapy - algorithms and applications

• Floating bottom mattress

• Hardened steel shaft and steel bearing to reduce friction as much as possible

As shown in the figure above, one of the three stops on the closed loop feedback path in the DRX device is the servo amplifier and the servo motor. The servo-amplifier receives the command to enter the required force calculation from the main control computer unit 13 times per second. The servo-motor itself contains a very precise device that measures force, speed and energy consumption. The servo amplifier monitors these variable values, correcting the servo input values ​​4000 times per second. A closed loop feedback system is one of the technological hallmarks of the DRX line of devices.
