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 system can be individually
adapted to your needs.
For this purpose, the product is adjusted by qualified personnel using adjustment software.
The product features MyModes for special motion types (e.g. cross-country skiing, ...). These are
pre-configured by the prosthetist using the adjustment software and can be activated with special
motion patterns, the remote control app and the optionally available remote control (see Page 78).
In case of a system malfunction, safety mode makes restricted operation possible. Predefined
resistance parameters are configured in the product for this purpose (see Page 84).
