A significant part of the costs of a pneumatic motion in a machine is caused by commissioning. Today every cylinder chamber needs to be connected by tube to the exactly right port of the valve terminal. In this paper a new concept for commissioning pneumatic systems is presented, where the tubes can be plugged in any arbitrary port of the valve terminal. So the commissioning can be fastened – and money can be saved. The concept bases on the Festo Motion Terminal, a new valve terminal whose valve slices can exercise different valve functions. The functionality change is made only by software. This versatility can be used for the automated commissioning.

In this article, we present a new concept of an active air spring, which can apply pressure and tension forces
independently of its deflection. The active strut mitigates body oscillations and improves the driving comfort
making it attractive for autonomous driving to avoid motion sickness. The model of the active air spring system
and the controller design are described. Furthermore, the suitability of the actuator concept for use in an active
chassis is shown. Finally, we show results of hardware-in-the-loop simulations.

In automated production systems handling is a key technology. Especially for gripping and clamping of
workpieces, vacuum automation plays an essential role in all industry segments. Core part of a vacuum gripping
system is the vacuum generation. Pneumatically driven vacuum generators are widespread in the handling
technology. Due to the technological development there are also new tasks and challenges, because in future
applications there is a trend that compressed air will hardly be available. In this paper it is presented, how
electrically driven vacuum generators can increase the energy efficiency of mobile handling systems and also in
addition to that can influence new forms of work, like human-robot collaboration.

Nowadays, assisted cough devices are widely used in airway mucus clearance for patients who cannot cough
autonomously. However, these devices use an open loop system where the inspiration pressure and time cannot
be adapted to each other, which may cause over or under-inflation. In this paper, a new simulated cough device
based on pneumatic system is presented. Moreover, a pressure-time adaptive algorithm is proposed to settle the
mismatching problem of inspiration pressure and time. Both simulation and experimental studies are conducted
to estimate the applicability of this algorithm for different compliance in a simulated lung. This paper provides a
constructive suggestion for the development of airway clearance technologies.
