Typically, in order to enable the handling of finepowders, chemicals are added to increase the flowability and reduce adhesion. This contributionshows that instead of additives also vibrations can be used to increase the flowability, to reduceadhesion and cohesion, and thus to enable or improve processes such as precision dosing, mixing,and transport of very fine powders. The methods for manipulating powder properties are describedin detail and prototypes for experimental studies are presented. It is shown that the handling of finepowders can be improved by using low-frequency, high-frequency or a combination of low- andhigh-frequency vibration.","lang":"eng"}]},{"abstract":[{"lang":"eng","text":"A measurement method is presented that combines the advantages of the multisine measurement technique with a prediction method for peak bending behavior.

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.

Thus, the bundle of motors has to act well organized and controlled to get an optimized drive that is not oversized and costly.","lang":"eng"}]},{"abstract":[{"text":"Piezoelectric transformers are well known since the publication of some patent applications at the end of the 1950s.
