Technology Offerings

This invention provides a device for the agglomeration of very finely distributed solids, colloids, or fibres, especially in elutriates, pasty goods, fine particle systems, and/or liquids (pelletization equipment) with alternative reactor geometry and a new reactor design that makes it possible to improve the agglomeration of suspended particles (with a size of > 1 µm) and to increase throughput of treatable substances, such as sludge or slurry.

In order to conduct vibration analyses to determine eigenfrequencies, modal damping, and eigenforms, a test specimen must be set into position and subjected to vibrations. The invention is an arrangement and process that simultaneously enables the free-free positioning of test specimens and the excitation of vibrations.

The new recombinant protein is based on the recently identified Cea1 adhesin from the yeast Pichia pastoris. It provides a high specificity for non-reducing N-acetylglucosamine (GlcNAc) ends of non-crystalline chitin, chitin-like polymers, or N-linked glycans, while recognition of glucose, glucosamine, or N-acetylneuraminic acid (Neu5Ac) is subordinate.
The technology therefore enables highly specific binding of chitin or chitin-like polymers in the context of biomedical or biotechnological applications.

The new method enables the determination of birefringence from unknown samples in absolute values without a calibration of the apparatus. Furthermore it allows a quantitative analysis of the materials with regard to robustness, elongation at rupture and colour uniformity. The method can easily be integrated in normal polarisation microscopes and provides the possibility of analysing optical retardation with spatial resolution.

While conventional sensor concepts are often not suitable for micro dimensions and too expensive, the new sensor system MicroDetec is ideal for continuous operating mode and sensitive flow conditions in microreactors. The measurement method exploits the phenomenon, that the fluids in biphasic flow in non-conductive micro channels undergo a polarization. This polarization is monitored by an electrode, which is flush fitted on a non-conductive channel (e.g. PTFE). To improve the signal / noise ratio, the measuring point is electrically shielded and the measuring signal is amplified. Micro process technology offers a lot of potential for the intensification of chemical, biochemical and pharmaceutical production. MicroDetec is protected by an international patent application. A first operating prototype has been built. PROvendis is offering licenses for the invention to interested companies on behalf of the TU Dortmund. There is also the possibility of collaboration with the inventors.

The invention describes a method to detect falls with the help of air pressure sensors. The sensors are attached to the patient’s body facing different directions in order to detect the dynamic pressure caused by a fall. At the same time those parts of the protection equipment protecting the specific part of the body that is likely to experience an impact based on the dynamic pressure are activated.
