A simple, feasible method for the production of laminate composites, consisting of a perforated substrate and a polymer membrane, now allows for the production of tactile displays the size of a computer screen. The procedure developed at Furtwangen University now enables the coating of large substrates with a high-quality membrane film, without creating air bubbles at the bond interface. The new method is environmentally-friendly, as the carrier is reusable and no chemicals are required to reduce adhesion. The procedure can be integrated into commercially available lamination systems.

Here we offer a technology that allows formation of III-V-material vertical nanowire lasers grown directly on a silicon wafer as a substrate. This opens the door to CMOS-conform production of telecom-lasers as well as new logical chip architectures.

Fatigue tests can be implemented for stents in different forms and fabrics, even grafts and drug eluting stents. The device is working at 20 kHz and can generate up to 50.000 load cycles per second. Test time is reduced from weeks to hours.

The invention provides a surgical tool, which generates a precise, pre-defined cut surface so that a good fit between the contact surfaces of the prosthesis and the bone is ensured.
The removal is affected by the use of a tool that has a vibrating unit and a holding part, which is important for directing to the bone.
There is an oscillating stroke movement along an axis parallel to the mounting direction of the joint prosthesis, as well as rotational movement about the same axis. The moving tool head has lying surfaces at an angle to one another, which are then adapted to the contact surfaces of joint prostheses. In order to produce defined-sectional areas, the holding part is fixed in the bone intramedullary, to ensure a guide of the surgical tool with fastening elements.

The invention relates to a constructive alteration of the ultrasonic transducers for an ultrasonic reflection and transmission measurement. The core of the invention is the placement of the transducers in a U-form with several ultrasonic transducers on the inside, which allow the measurement of irregular bodies and bodies with high ultrasonic dampening. Additionally the device uses constant flow of coupling agents by pumps. Several openings on the inside provide the testing body with a suitable agent with ensures the required coupling of the materials.

The present invention using the acoustically induced laser scattering (ALS) avoids these disadvantages by applying the principle of the acousto-optical modulation. By an appropriate arrangement of an ultraultrasonic source, a sonic grid which diffracts laser light is generated in the material. By exclusively using the diffraction peak of
the laser light in a test object, the invention enables new possibilities of non-invasive determination of relevant rheological and other mechanical properties. With this method, a non-destructive measurement of little technical effort and very short measuring times gets possible. Especially
it is, in contrast to conventional rheometers, suitable for in situ measurements. Thus, the invention has a big market potential in the fields of materials science, materials testing and quality assurance.
