The House Stands Swaying

12.10.2005


An automatic guard has been developed to check that houses or other buildings do not sway, or move away from their true vertical position. If dangerous degrees of tilt are found, the device immediately notifies engineers. This spatial meter, called PIKiN-03, has been designed by Moscow engineers to measure vibrations and tilts in three dimensions.



Such measuring devices designed by engineers of the Conus (Cone) company are capable of around the clock checking that the permissible house, crosstops or bearings tilt should not be exceeded, and whether it is time if not evacuate the lodgers then at least to repair the house immediately.

The ‘heart’ of the new device are micromechanical accelerometers, i.e. acceleration measuring devices. These are diminutive devices that allow to determine and record the slightest deviations of the entire construction from the initial position. The meter constitutes a thin ‘arm’ (as the specialists call it) etched in the silicon crystal (a cube with the side equal to 2 mm), i.e. a bar inside the host crystal.


When the silicon arm’s position in space changes, it bends under the action of gravity. This mechanical stress leads to appearance of electric signal that can be measured, having preliminarily been amplified and digitized. Three such accelerometers located transversely to each other allow to measure deviations of the entire constriction in three dimensions.

Each of these tilt measuring device is small: the volume being 5 cubic centimeters, it weighs only 150 grams. The device can provide the information continuously within the temperature range from minus 40 through plus 50 degrees Celsius. Most importantly, the device can record the 30-degree deviation with surprising precision – up to the tenth part of angular minute.

“Certainly, preventive monitoring systems for construction structures should be equipped with several sensors, says Yuri Titov, head of the subject, chief designer, Research & Production Enterprise Conus (Cone) company. Cables are also needed to communicate the data obtained from the meters to the supervisor’s common control panel, indicator lamps and audio indicators are required to give signals in case the deviation of, for example, a house exceeds the permissible value. Any house is permanently slightly swinging to and fro, we simply do not notice that. However, some deviations are permissible and some are dangerous. Our devices will help to reveal the dangerous ones.”

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
