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 the
needs of the patient.
For this purpose, the product is configured with the "C-Soft Plus" adjustment software.
The product features MyModes for special motion patterns (e.g. cross-country skiing, ...). These are pre-con­
figured using the adjustment software and can be activated with special motion patterns, the remote control app
and the optionally available remote control (see Page 82).
In case of a system malfunction, safety mode makes restricted operation possible. Predefined resistance paramet­
ers are configured in the product for this purpose (see Page 87).
Empty battery mode permits safe walking when the battery is drained. Resistance parameters that are predefined
by the product are configured for this purpose (see Page 87).
