Overview on Adaptronics and the Future with Smart Embedded Systems

Noise and vibration exposure for humans has been of interest for many years. Empirical data has verified that too high dose values can create multiple problems to a human body - often severe. Therefore, spot dose measurements have been used to verify that exposure levels are within acceptable limits. In 2006, the European Machinery Directive increased the responsibility for manufacturers and employers to make sure that limits are in compliance with legislation. The type of classical technology currently used, often employs passive solutions aimed at trying to reduce noise and vibration levels. For low frequency applications, these methods are often inadequate and lack the required level of performance. A smart combination of passive and active techniques can provide many improvements. Today, with possibilities for low cost and embedded electronics, and the rapid development of new actuators, a vast range of applications are possible for this combined approach. A financial advantage also exists when combining active and passive control methods. Today, multiple products utilize embedded "electronic muscles" that counteract harmful sound and vibrations in real-time - featuring advanced control systems. All this then becomes an invisible function in the vehicle, machine, or tool. The launch of such systems and successful acceptance requires international compliance with applicable standards. Via extensive international networks and scientific leadership in multiple organizations, we have managed to develop a range of new products meeting the requirements of international standards. One project, I-SPIDER, is aimed at addressing environmental parameters in schools: an area where our new smart and embedded technology plays a key role. Acticut®, the company that won the Large Embedded Award in Sweden (2006) is another example of how a smart and embedded system can accomplish a task that many people believe to be impossible. New sensor concepts and approaches in combination with consumer and automotive wireless and network solutions are key ingredients for success. It is impossible to imagine how the smart and embedded technology will revolutionize the sound and vibration business and open completely new business segments. This paper will outline these new markets and applications.
