  text: Self-optimizing mechatronic systems are a new class of technical systems.
    On the one hand, new challenges regarding dependability arise from their additional
    complexity and adaptivity. On the other hand, their abilities enable new concepts
    and methods to improve the dependability of mechatronic systems. This paper introduces
    a multi-level dependability concept for self-optimizing mechatronic systems and
    shows how planning can be used to improve the availability and reliability of
    systems in the operating stages.

  text: New mechatronic systems, called self-optimizing systems, are able to adapt
    their behavior according to environmental, user and system specific influences.
    Self-optimizing systems are complex and due to their non-deterministic behavior
    comprise hidden risks, which cannot be foreseen in the design phase of the system.
    Therefore, this paper presents modifications of the current condition monitoring
    policy, to be able to cope with this new kind of systems. Beside avoiding critical
    situations evoked by self-optimization, the proposed concept uses self-optimization
    to increase the dependability of the system. In this case, the concept is applied
    to the active guidance module of an innovative rail-bound vehicle.

  text: A simple pre-stress estimate method of Langevin transducers is studied. The
    measurement setup consists of a capacitor, an impedance converter and a voltmeter.
    Based on the piezoelectric equation and the basic circuit theory, the mathematical
    expression between the pre-stress and the voltage across the capacitor is derived.
    The pre-stress level can then be calculated out of the measurement of the capacitor
    voltage. In order to evaluate the precision of this method, a force washer is
    used to measure the pre-stress of the Langevin transducer. The result shows the
    pre-stress level obtained from this method is 30-40\% higher than the pre-stress
    level measured by the force washer. This method is simple and can be used to estimate
    the pre-stress of various Langevin transducers. The precision of this method can
    be raised if d33 is identified under different pre-stress levels.

  text: 'Several positioning tasks demand translatory drive instead of rotary motion.
    To achieve drives that are capable e.g. to drive the sunroof of a car or to lift
    a car''s window, multiple miniaturized motors can be combined. But in this case
    many other questions arise: the electromechanical behavior of the individual motors
    differs slightly, the motor characteristics are strongly dependent on the driving
    parameters and the driven load, many applications need some extra power for special
    cases like overcoming higher forces periodically. Thus, the bundle of motors has
    to act well organized and controlled to get an optimized drive that is not oversized
    and costly.'
