Building on university research, Greek SMEs can now apply electronics circuitry for digital signal processing (DSP) to multimedia audio equipment thanks to funding from the European Commissions IST programme.
Under the project name of HIPRO, the coordinating organisation Spectrum Electronics Company S.A learnt how to apply sophisticated DSP technology, a highly technical area involving complex mathematics as a result of the technology transfer of microelectronics know-how from project partner University of Athens.
The great advantage of such a numerical approach versus any analogue process is its reproducibility. Once a numerical procedure is settled, it becomes an easy task to duplicate without failure and thoroughly maintain the quality of the result. This explains why the DSP technology has found its place in many electronics applications such as radio, high definition television, high-end audio, etc.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
