Hannover Messe: Quiet area for sensitive devices

2011-03-16
(Press-News.org) It is difficult to write a letter on a driving bus, or to measure small distances on a vibrating plate – the vibrations simply interfere too much. Any small vibration coming from the floor is already too much if there is an increased requirement with respect to accuracy. They hamper high-resolution measurements of distance or roughness – as in scanning electron microscopy. They are also not desired in production if precision is a requirement. For this reason, the devices must be settled in such a manner that they are stable and quiet. Damping is necessary also when the machines/devices themselves vibrate and this movement is not supposed to be transferred to the flooring.

The adaptronics specialists of the Fraunhofer Adaptronics Alliance have developed an insulation unit that meets these requirements and is compact at the same time. With the help of piezo-electric ceramics, the researchers were able to integrate all necessary functions into a single, adaptronic component. It provides requisite rigidity, registers vibrations and counteracts them actively. This makes the unit superior to the current solutions for vibration insulation. In contrast to passive solutions – for example, using rubber elements under machines – the new solution works at even very low interference frequencies. However, traditional mechatronic insulation systems are able to do that as well. They actively attract the forces, just like the platform, and then counteract the movement, so to speak. Their disadvantage: they are comparatively large and consist of many components.

"One of the particular advantages in the insulation unit that we developed lies in the implemented digital control. This results in a particularly high flexibility, which cannot be achieved in this manner using analog controls," says Dr. Tobias Melz, managing director of the Fraunhofer Adaptronics Alliance. "The platform can be used not only for small machines or devices, but also for large ones, as it is relatively easy to adapt with respect to size. Our system can be implemented in such a compact and flexible manner that it could be integrated directly into the machines, for example into measuring instruments and production systems. The respective system need not be set up on a platform; rather, it is able to insulate itself from the vibration," explains Dipl.-Ing. Torsten Bartel, the responsible project manager at the Fraunhofer Institute for Structural Durability and System Reliability LBF.

Torsten Bartel and his colleagues are presenting the platform at work at the Hannover Messe: It already insulates against vibration in one spatial direction and two rotational movements. In addition, the experts are introducing an element that makes it possible to achieve damping effects in additional spatial directions. In the future, they want to expand the platform such that it will dampen all six directional movements of the setup machine/device.

Strategies for improved collection of national travel data

2011-03-16
WASHINGTON — Good travel data are essential to measure and monitor the performance of the U.S. transportation system and to help guide policy choices and investments in transportation infrastructure, says a new report from the National Research Council that calls for the creation of a national travel data program. Current data are inadequate to support decision making in the transportation sector. "Each day our transportation network serves hundreds of millions of travelers and handles millions of tons of freight, yet we are not collecting the data necessary to analyze ...

'Openness prevails' -- have Obama's promises fallen short?

2011-03-16
London, UK (March 15th, 2011) – WikiLeak's disclosures highlight longstanding problems of the overclassification of information and failure of transparency laws, says David L Sobel. When Barack Obama took office as president in January 2009, he identified transparency as one of the highest priorities on his agenda for change. Writing in the current issue of Index on Censorship, David L Sobel, senior counsel at the Electronic Frontier Foundation in the US, suggests that the president's early promises remain unfulfilled. He argues that, with the US government's failure ...

Wright Law Offices: Bankruptcy in Kingman, Arizona

2011-03-16
Mohave County and its major areas of Kingman, Bullhead City, and Lake Havasu City are especially vulnerable to the poor economic times facing our country. Recently the Kingman Daily Miner reported that the Kingman and Lake Havasu areas had an unemployment rate of 10.2%, this is higher than the Arizona average of 9.4%. The biggest problem with this statistic is that it does not take in to account all the people that have either stopped looking for work or are underemployed. There is currently an epidemic of of unemployment and underemployment in Kingman, Arizona, as well ...

Collectibles can trigger obsessive-compulsive disorder in vulnerable people

2011-03-16
The massive marketing campaigns launched by publishing houses at the start of the academic year can cause people bound to suffer obsessive-compulsive disorder to develop this pathology before. The fact is that collecting articles without control is a symptom of this serious psychological disorder –one of which most known variants is Diogenes syndrom– and of shopping addiction. These are two mental disorders affecting approximately 12% of the population. Porcelain dolls, precious stones, world thimbles, watches, fans, dinosaurs, language courses, and tanks and ships in ...

The new adulthood: Extended parental support as a safety net

2011-03-16
Minneapolis, MN —March 15, 2011—A new study from the Journal of Marriage and Family shows that contrary to popular anxieties about slacker young adults who refuse to grow up, or indulgent parents who stifle their adult children's development by continuing to support them, there is evidence that parental assistance in early adulthood promotes progress toward autonomy and self-reliance. Study author Teresa Swartz, "The fact that young people depend so heavily upon their parents well beyond the age when most people from earlier generations had already started families and ...

New insights into cancer treatment

2011-03-16
Leuven - Jean-Christophe Marine (VIB, K.U.Leuven) strongly argues against the use of Cop1-inhibitory drugs. The protein Cop1 has –for a long time - been seen as an attractive drug target for cancer. But Jean-Christophe Marine found out that Cop1 acts as a tumor suppressor, and thus inhibits tumor formation. His new data will have direct implications for the development of cancer drug targets. Tumorigenesis: loss of control Tumors form when control over the cell division is lost; a process that could be compared to losing control over the speed of your car. Two main players ...

Surgical Mistakes More Common Than Patients Believe

2011-03-16
It is every patient's worst nightmare: to wake up in the recovery room after surgery to learn that something went wrong. In some cases, the bad outcome is simply a matter of chance: one of the known risks of the surgery happened to occur. But in other cases, the bad outcome is the direct result of the negligence of the physician performing the surgery and was entirely avoidable. Surgical mistakes happen much more often than most Americans realize. Sometimes these mistakes are minor and may never cause any harm to the patients, but this is not always the case. According ...

Apnea may be cause for awakening and voiding for those with enlarged prostates report Ben-Gurion U.

2011-03-16
BEER-SHEVA, ISRAEL, March 15, 2011– Ben-Gurion University of the Negev (BGU) researchers have shown that a significant number of patients with benign prostate enlargement (BPE) may have Obstructive Sleep Apnea (OSA), which may be the reason for their night awakenings and urination. This study compared men between the ages of 55 and 75 who were randomly sampled from primary care clinics, diagnosed with BPE and reported nocturia at least once nightly. The comparison control group had no BPE and one or no nocturia episodes per night. According to the new study published ...

All wrapped up: K-State researcher's graphene cloak protects bacteria, leading to better images

2011-03-16
MANHATTAN, KAN. -- It's a cloak that surpasses all others: a microscopic carbon cloak made of graphene that could change the way bacteria and other cells are imaged. Vikas Berry, assistant professor of chemical engineering at Kansas State University, and his research team are wrapping bacteria with graphene to address current challenges with imaging bacteria under electron microscopes. Berry's method creates a carbon cloak that protects the bacteria, allowing them to be imaged at their natural size and increasing the image's resolution. Graphene is a form of carbon ...

EARTH: Still in a haze: Black carbon

2011-03-16
Alexandria, VA - Black carbon - fine particles of soot in the atmosphere produced from the burning of fossil fuels or biomass - a major contributor to the thick hazes of pollution hovering over cities around the world, has been known to be a health hazard for decades. But over the last decade, scientists have been examining in increasing detail the various ways in which these particles contribute to another hazard: heating up the planet. Black carbon's impact on climate is not cut-and-dried, however, as EARTH explores in "Still in a Haze: What We Don't Know About Black ...
