Flexible sensor system monitors objects and protects people all over the world via mobile networks

Siemens Automation and Drives (A&D) will be presenting its AySystem for the first time at the 3GSM World Congress in Barcelona from February 12-15, 2007.

Usable worldwide, this GSM/GPRS solution consists of the Ay terminal as the basis communication device and portal, a web interface which can be used for centralized security and monitoring applications as well as for configuring and monitoring the basis devices. Based on Java technology, the system is suitable both for mobile applications in the private sphere and for companies who want to protect their employees and monitor objects.

Three sensors are integrated in the Ay device for detecting temperature, volume and motion. If a predefined sensor threshold is exceeded, an alert is triggered via the GSM/GPRS mobile radio network. The system settings can be entered and adjusted remotely via the web interface. In the same way, the measured values of the sensors can be read, displayed, analyzed and integrated into customer specific applications. The Ay device is the same size as a stack of playing cards and is fitted with four touch-sensitive function keys, a large display which can be used as a button and a loudspeaker which functions as a siren as well. The user only has to press the button to trigger emergency calls in the form of a telephone call or an SMS. Another important feature is the two-way communication function that can be used for telephone calls or sending and receiving SMS messages. The device functions can be set as required via the web interface. The only requirement is access to the Internet. As an alternative, the configuration can be done by the user on the device itself using the function keys and the display to enter settings directly. For professional applications, the device is preferably configured and remotely controlled from a central location, so that configuration by the user is not necessary.

For customized solutions, the modular-design device can be easily supplemented with AySnapOn expansion modules and programmed by means of Java technology. A GPS module, for example, can be used for locating people and objects and a camera can be added for extending the security functions. The web interface,, can easily be adapted to the requirements of companies that themselves have wireless communication components and are looking for a server solution for their own individual applications.

The list of potential AySystem applications is almost endless. Thanks to the intuitive, easy-to-use display and the function keys, the Ay user can trigger special actions via mobile radio quickly and easily. There are applications suitable for children and people with infirmities, as well as for security guards and field personnel. In addition, the three integrated sensors for temperature, volume and movement enable a wide range of uses, from individual object monitoring to the management of entire vehicle fleets. Thanks to its open interfaces, the AySystem accelerates time-to-market and requires only low initial investment overhead for the mobile radio operator or business customer. Moreover, the system is scalable both in terms of the hardware, due to the snap-on concept, and as regards software in the form of a Java client-server solution. It can grow as requirements increase.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
