Data Physics will be exhibiting its SignalStar Vibration Controllers. Dynamic Signal Analysis and Closed loop vibration control are realtime applications requiring intensive numerical computation. The recently introduced scalable DSPcentric signal analysis engine, Abacus, provides a single platform uniquely suited for both realtime dynamic signal analysis and vibration control applications. SignalStar vibration controllers combine the power of a distributed DSP architecture and the acclaimed Data Physics control algorithms, delivering uncompromised control performance from 1 to 1000 channels.

The new family of SignalStar vibration controllers running on Abacus offer complete coverage of vibration testing including: Random, Sine, Resonance Search and Dwell, Classical Shock, Transient, SRS, Mixed Mode, and Time Data Replication, for single shaker and multi shaker test requirements. Any number of input channels can be combined to form an averaged or extremal control signal while the remaining inputs may be used as limit channels to protect the test item. Differential inputs on all channels eliminate potential ground loop problems and provide a high level of protection against noisy environments. With a 24 bit ADC per channel, you get increased signal-to-noise ratio for accurate measurements required to control "high-Q" resonances or deeply notched references. Dual cascaded DACs with reconstruction filters generate pure analog signals for all applications, including true analog sine-sweep to excite all frequencies in a specified band.

Data Physics has been supplying high performance solutions in signal processing to the noise and vibration community for the past 20 years. With the addition of a full line of electrodynamic shakers to complement its vibration controllers and dynamic signal analyzers, Data Physics is a total solution supplier for vibration applications.

SATCON TO FORM STRATEGIC ALLIANCE FOR MARKETING AND SALES OF LING SHAKER TEST SYSTEMS

 SatCon and Data Physics Corporation sign Letter of Intent to form Strategic Alliance.

Cambridge, MA -- March 30, 2004 -- SatCon Technology Corporation® (Nasdaq NM: SATC ), a manufacturer of electronic power control systems, today announced that it has signed a letter of intent to form a strategic alliance with Data Physics Corporation for the marketing and sales of SatCon's Ling Vibration and Acoustic test systems.

"It is SatCon's strategy to form strategic alliances and partnerships where we believe such relationships will provide for improved access to markets which should result in increased product sales and revenue," said David Eisenhaure, SatCon's president and CEO . "We believe that Data Physics is well positioned to return our Ling Products to a strong market presence because they have a broader sales and marketing base. This should result in better sales both nationally and internationally for our vibration test systems and amplifiers."

"Data Physics is a leading supplier of Noise and Vibration test instruments," said Sri Welaratna, president & CEO of Data Physics Corporation. "Users of Data Physics Vibration Controllers mostly use Electro Dynamic Shakers to create the controlled vibrations required for environmental vibration testing. Similarly, users of Data Physics Dynamic Signal Analyzers use small Electro Dynamic Shakers to excite structures for Modal testing. In acoustic test chambers, where Ling Acoustic Transducers are used, the measurement and control of precise levels of noise require the analyzers and controllers like those made by Data Physics."

"It therefore makes great sense to offer the analyzers and controllers with the shakers and acoustic transducers together. Not only can the combination be marketed more economically the user can also be provided a more complete test solution."

Concluded Welaratna, "Ling electro-dynamic shakers are renowned for superior design that offers more vibration force per unit size and Data Physics dynamic signal analyzers and vibration controllers are renowned for superior technology that offer higher performance and accuracy. Users will now be able to buy a complete test solution of the highest quality and performance from one source."

Under the agreement, SatCon would continue the design, development and manufacture of Ling Products, including shakers, amplifiers, mechanical accessories and acoustic devices. SatCon will sell Ling Products exclusively through Data Physics. Data Physics, in turn, agrees to market and sell exclusively the Ling Products line on a worldwide basis and agrees not to market and sell any vibration and acoustic test systems that directly compete with the Ling Products line.

It is expected that the final Strategic Alliance agreement will be signed and effective within the next few weeks.

Visit Data Physics at IMAC XXII - Booth 111

IMAC-XXII: A Conference & Exposition on Structural Dynamics, Theme: Linking Test to Design, will be held at the Hyatt Regency, Dearborn, Michigan USA on January 27-29, 2004. In the late 1970’s and early 1980’s, technical advances in fast Fourier transform equipment coupled with personal computers propelled the interest of modal analysis as an analytical tool. It was then possible to collect and analyze many channels of data simultaneously, which gave the experimentalist a whole new way to understand and solve vibration and dynamics problems. In 1981, two General Electric engineers, Dominick DeMichele and Peter Juhl recognized the need to organize the modal community within one specific event. With the initial help of Union College (Schenectady, New York), these two men organized the first IMAC in 1982 in Orlando, Florida. It was an immediate success, as it brought together an active group of international scientists, engineers and hardware and software professionals. More information can be found at http://www.sem.org/CONF-IMAC-TOP.asp

Visiting the exhibition is a great opportunity to keep up with the latest technology and to discover new products related to structural dynamics.

Airbus selects Data Physics Dynamic Signal Analyzer and Vibration Controller packages for A380 development

Airbus, a division of the European Aeronautic Defense and Space Company (EADS), has selected Data Physics SignalCalc Dynamic Signal Analyzers and SignalStar Vibration Controllers as the standard test and measurement instrumentation for use during the development of the A380. Flagship of the 21st century, the A380 will have seating capacity for 555 passengers and a range of about 14,800 km. First flights are scheduled for 2006.

After several months of competitive evaluation at Airbus in Toulouse, France, the Acoustic & Vibration group selected Data Physics against another European supplier. Factors leading to Data Physics solution include:

Hardware versatility – Airbus purchased five 32 input and 8 output channel Abacus based systems that can be used individually or pulled together to form a 160 channel system. Abacus architecture allows 8 channel boards to be combined to make 32 channel subsystems which in turn can be connected on a 1 Gigabit network to make a thousand channel system. The modularity allows a dynamics laboratory to use portable instruments of varying sizes which can be united to form a large channel count system for occasional use in larger applications.

Breadth of application coverage – Airbus will be performing both dynamic signal analysis and vibration control on one hardware platform. Analysis includes basic FFT, Real Time Octave and MIMO; Control includes Random, Sine, Shock and Time Data Replication both in single and 6 axis. Additionally, the system also includes Normal Mode Analysis for Ground Vibration testing.

High performance data record to disk – Airbus requires the system to store all input channels to disk, during both analysis and control, at full bandwidth, for further post-processing. The high performance local disk architecture of Abacus allows recording of all channels to disc while making a variety of realtime dynamic signal analysis measurements.

Ease of use – Airbus was able to setup and run tests more efficiently and faster than with competitive products. The SignalCalc and SignalStar user interface provides intuitive organization of control panels and flexible display of results. A common user interface across applications for both small and high channel count system makes for a shorter learning curve and overall lower training costs.
