The newly developed method only requires the detection of movement directions of light patterns (speckles) for the determination of refractive error of the human eye. The subjective evaluation of the effect of the corrective lenses by the patient can thus be reduced to a simple question (e.g. right/left).
The present invention suggests a novel laser-based system, which allows for a contact-free measurement of deformations/strains. The system can be easily implemented in complex testing setups and yields enhanced performance characteristics.
Novel technology to predict iron clogging and corrosion in water and hydraulic systems
Corrosion and iron clogging are commonly known problems in hydraulic systems. These phenomena are potentially causing great damage to the system or have negative impact on system performance. Scientists at the Leuphana University of Lüneburg developed a novel method to predict iron clogging in water and hydraulic systems.
Presented here is a filter unit that has one or multiple microwave resonators integrated into its filter material, whereby filter load can be monitored during operation. Thus, filter exchange intervals can be adjusted to actual filter capacity.
Improved method for alignment and sorting of cells in flow cytometry
Here we present two new methods for flow cytometry and fluorescence-activated cell sorting. Both methods are suitable for the so-called 'sexing' of spermatozoa as well as for many other applications of fluorescence-activated cell sorting and impose less stress on the sorted material than conventional techniques.
The following invention represents a possibility to identify infusions when administered by an injection pump. The method involves a combination of Raman spectroscopy and refractometry. Both methods of analysis are based on instrumental analysis. Furthermore, algorithms are used for the evaluation which can be assigned to indirect hard modelling and statistics.
