2 Product description

2.1 Design
The product consists of the following components:
2.2 Function
This product features microprocessor control of the stance and swing phase.
The microprocessor uses the measurements of an integrated sensor system as a basis to control
a hydraulic unit that influences the damping behaviour of the product.
These sensor data are updated and evaluated 100 times per second. As a result, the behaviour of
the product is adapted to the current motion situation (gait phase) dynamically and in real time.
Thanks to the microprocessor-controlled stance and swing phase, the product can be individually
adapted to your needs.
For this purpose, the product is adjusted by qualified personnel using adjustment software.
