This innovation comprises a novel measurement device which uses the structure-
borne noise of a moving component to detect whether there is a fault in it. The
methods used up to now have specific disadvantages in their current application.
Normal spectrum analyses of structure-borne noise, for example, usually rely heavily
on assumptions about the operating environment, are highly computer-intensive and
are effectively blind to weak and static signals with an unstable phase position.
The novel measurement device bases its analysis on the entropy value calculated
from the probability of the different frequencies of the structure-borne noise. A
possible fault can therefore be detected at an early stage and in a reliable manner
without any additional assumptions.
This invention describes “solid-state” sensors with electrical control of the affinity of chemosensitive materials. This configuration enables rapid regeneration of sensors after analyte binding and increases selectivity. The sensor has been designed as a six-electrode chemoresistor that contains four electrodes in the center for separate measurements of resistance as well as two other external electrodes to monitor the redox status of the sensor material.
This object is accomplished in the format of a solid-state chemosensor.
This invention proposes a method to make plants more resistant to (repeated) heat stress. This is done by means of using microRNA156 (miRNA156) to increase heat stress tolerance. miRNA156 is expressed under the control of a special heat-inducible promoter to minimize negative side effects such as enhanced leaf induction and later flowering. The proposed invention expresses miRNA156 exclusively by means of heat. The heat-inducible promoter HSP21 ensures that the expression of miR156 is “switched on” by
the application of heat.
