Zusammenfassung des Vortrags am 23. April:
The temporomandibular joint might be small in size compared to hip or shoulder joints, but it is of great importance in our daily life. It provides various movements allowing us – among other things – to eat and speak. However, it is also sensible to different pathologies which are often linked to the temporomandibular joint disc. This fibrocartilage pad serves as a stress distributor between the joint’s bony structures and enables a smooth jaw movement. In order to simulate the temporomandibular joint disc under various conditions and to search for future materials that can substitute the disc, it is necessary to properly understand and describe the temporomandibular joint disc’s biomechanical behaviour. The presentation will give an insight in acquisition of the disc’s external shape and internal microstructure as well as experimental characterisation via spherical compression tests. Furthermore, a first numerical attempt to study the temporomandibular joint disc using an inverse method will be presented.

QWCD Signallight new at ghv

The ghv expands its product range with a new series of Qlight. The QWCD series convinces with exclusive design and innovative construction – signal horn and warning light are combined in one product.

Noisy production environments, dust and high ceilings pose a challenge when it comes to the corresponding warning and alarm systems. Acoustic and visual warning signs are used, usually consisting of a warning light and a separate horn.

Qlight has revolutionised these two individual devices and combined them into one compact product. The use of polycarbonate (PC) in the construction of the horn allows the tone generator to function as a warning light at the same time.

The ABS housing and the high IP66 degree of protection guarantee excellent resistance when used in environments exposed to high dust levels, weather conditions and extreme temperatures from -50°C to +60°C. The ABS housing is designed to withstand high temperatures.

Thanks to its water- and dust-proof structure and a noise level of up to 123 dB, the QWCD series has proven itself in many shipbuilding, factory and mining applications. The QWCD offers integrated warning tones in the standard version 31, which can be set via a DIP switch. With the -SD version, it is possible to control 31 self-recorded tones via a binary input.

Due to its compact design, the QWCD can be installed almost anywhere, which is a great advantage. Both sizes, the QWCD35 and the QWCD50, are available in red, yellow, green and blue.

Innovative „Train Ring“ is the best rail train solution

.

Reduce Cost with High Customer Satisfaction

During current train operation, train cars might need to be separated and reoriented due to more flexible operating requirement. Take MRT for example, it needs more cars during peak hours while only few cars are needed during offpeak hours. A longdistance train route may separate into two shorter trains and heading to different destinations at a junction point. When a train system has higher flexibility, it can utilize the resource and reduces operational costs.

When train cars are switched, reconfigure network settings is normally required. Thus, railway operators need to have enough knowledge of Ethernet. This not only increases the cost of labor but also result in additional time. Also, train car switching will cause the interruption of networks, effecting passenger information system and intrain WiFi service.

Passenger’s tolerance toward network interruption is limited and this is one of the important factors of customer satisfaction.

Train Ring vs. Existing Solutions

Common Rapid Spanning Tree Protocol (RSTP) and Coupling Ring can be applied to rail train network for redundancy of multiple train cars. However, each solution has its own drawbacks such as longer recovery time or nonautomatic recovery. Lantech provides a new solution called "Train Ring", which can automatically recover the network within 50ms without reconfigure the settings!

Lantech Train Ring is evolved from traditional Coupling Ring. It eliminates the setting process, and will automatically identify the primary and backup path dynamically, without any configuration required.

Lantech Train Ring allows train operators to rapidly change composition of trains with high efficiency and flexibility. Since all settings are done automatically, configuration errors and cost can be minimized. The recovery time of Train Ring is less than 50ms, so passengers can hardly recognize the interruption caused by topology change.

New circulating cooler with CO2 refrigerant

With the new Unichiller 220Tw CO2, Huber Kältemaschinenbau presents another milestone in environmentally friendly refrigeration technology. The new chiller uses CO2 as a refrigerant. CO2 or carbon dioxide (also known as R744) is a natural component of air and has been proven in refrigeration since the 19th century. The colorless gas liquefied under pressure, has no ozone depletion potential (ODP = 0), and has a negligible greenhouse gas potential with a GWP = 1. If, for example, 1 kg of CO2 enters the atmosphere through a leak in the refrigerating circuit, this is 3780 times less damaging than with the conventional refrigerant R404A. In addition, CO2 is a so-called natural refrigerant which occurs in very large quantities in nature, i.e. it does not have to be generated with great energy expenditure. In addition, CO2 is non-flammable, non-toxic and chemically inert.

The new Unichiller CO2 is therefore a 100% environmentally friendly alternative to refrigerators with conventional synthetic refrigerants. The Unichiller is designed for working temperatures from -20 to +100°C, and offers a cooling capacity of 22 kW and a heating capacity of 12 kW. The circulation pump achieves a delivery rate of 200 l/min and 4.6 bar pressure. The cooler is equipped with the Pilot ONE touch-screen controller and therefore has numerous professional functions for demanding temperature control tasks.

Advantages:

  • Proven Unichiller technology
  • Environmentally friendly refrigeration technology
  • Ozone depletion potential equal to zero (ODP = 0)
  • Global warming potential negligible (GWP = 1)
  • Very good energy efficiency
  • Refrigerant non-flammable, non-toxic
  • High operational safety
  • Future-proof investment
    (not affected by the F-gas regulation)

ecsec supports trustworthy digitalisation under hand and seal

The Federal Office for Information Security has published new versions of the Technical Guidelines for "Replacement Scanning" (RESISCAN) and the "Preservation of Evidence of Cryptographically Signed Documents" (TR-ESOR), developed with the support of ecsec, which provide the basis for efficient and secure digitalisation of business and public administration.

Secure digital administration processes thanks to RESISCAN, E-File, TR-ESOR & Co.

As part of the digitalisation strategy of the new German Federal Government, the electronic transaction processing in public administration (E-File) plays an important role. The Federal Government’s E-Government Act has already provided regulations for the "Electronic record-keeping" (§ 6 EGovG) and the "Conversion and destruction of the original paper document" (§ 7 EGovG) since 2013, whereby the systems and processes used must be protected using state-of-the-art security measures. The required and recommended measures are described in the relevant Technical Guidelines of the Federal Office for Information Security, such as BSI TR-03125 (TR-ESOR, "Preservation of Evidence of Cryptographically Signed Document ") and BSI TR-03138 (TR-RESISCAN, "Replacement Scanning"). With the support of ecsec both guidelines were recently updated and adapted, among other things, to the legal framework of the pan-European eIDAS-Regulation (EU) No 910/2014 and General Data Protection Regulation (GDPR) (EU) No 2016/679.

eIDAS-Regulation creates opportunities for secure and efficient digitalisation

Both the substituting scanning according to version 1.2 of BSI TR-03138 (RESISCAN) and the preservation of evidence of cryptographically signed documents in accordance with version 1.2.1 of BSI TR-03125 (TR-ESOR) result in organisational relief. Electronic seals that are assigned to legal persons can now, for example, be used in scanning processes to protect the integrity and evidence of scanned documents. These new options for the implementation of TR-RESISCAN have already been applied by first users in the federal administration, such as the Federal Railway Estate Authority – a federal authority within the scope of the Federal Ministry of Transport and Digital Infrastructure. Thus, the annually scanned 250,000 documents with 1.2 million pages no longer have to be archived in paper form, but can now be electronically stored and processed in an E-File.

"The Technical Guidelines of the Federal Office for Information Security provide the basis for the secure electronic handling of economical and administrative business processes," adds Dr. Detlef Hühnlein, CEO of ecsec GmbH. "We are very pleased that the opportunities for trustworthy digitalisation offered by the eIDAS-Regulation are increasingly being recognised and used by authorities."

Current version of guidelines available at https://resiscan.de and https://tr-esor.de

The current version 1.2 of the BSI TR-03138 “Replacement Scanning” (RESISCAN) is available at https://resiscan.de and comprises in addition to the main document with the modular requirements catalogue, a test specification (Annex P), the result of a generic risk analysis (Annex A), answers to frequently asked questions (Annex F), non-binding legal advice on the use of TR-RESISCAN (Annex R) and an exemplary process instruction (Annex V).

The current version 1.2.1 of BSI TR-03125 “Preservation of Evidence of Cryptographically Signed Documents” (TR-ESOR) is available at https://tr-esor.de providing recommendations for a reference architecture including its processes, modules and interfaces as a concept of a Middleware, requirements for data, document and exchange formats for archive data objects and evidence data, as well as additional requirements for federal authorities and compliance rules for various levels of compliance

100% target achievement by KECK for centrotherm

The SNEC PV Power Expo in Shanghai is not only the largest trade fair in the Asian photovoltaic industry, but also the most important globally. The technology provider Centrotherm took the opportunity to present highly efficient solar cell concepts and the associated production solutions to an international audience.

There were two extraordinary highlights:
The new centrotherm LPCVD production system c.DEPO LP, which ranks number five of the 25 most innovative production solutions for the photovoltaic industry. As well as the flexibilty app on the trade fair stand, which demonstrates the special variety of centrotherm production solutions to the public.

The KECK team faced two great challenges in the concept development stage. On the one hand, the aim was to surpass the great results from the 2017 event. On the other hand, the stand had to have an innovative design that was consistent with the highlights, and which could be realised at a very high standard despite the short set up and dismantling time.

The new trade fair stand design was characterised by the impressive façade made of large, blackened glass elements, in which the large-format (3 x 7 m) LED surface was integrated. Thanks to the two-storey structure, there was enough space to present the products in a way that would attract visitors, as well as enable in-depth discussions on the quieter upper level.

In the end, it was “mission accomplished” for KECK.
