2 Product description

2.1 Design

The product consists of the following components:

2.2 Function

This product features microprocessor-controlled damping of plantar flexion (motion of the foot in
the ankle joint in the direction of the sole of the foot) and dorsiflexion (motion of the foot in the
ankle joint in the direction of the instep).
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 damping of the plantar flexion and dorsiflexion, the
product can be individually adapted to requirements.
For this purpose, the product is adjusted by qualified personnel using adjustment software.
