A set of physically based retrieval algorithms has been developed to derive from multispectral satellite imagery a variety of cloud properties that can be used to diagnose icing conditions when upper-level clouds are absent. The algorithms are being applied in near-real time to the Geostationary Operational Environmental Satellite (GOES) data over Florida, the Southern Great Plains, and the midwestern USA. The products are available in image and digital formats on the world-wide web. The analysis system is being upgraded to analyze GOES data over the CONUS. Validation, 24-hour processing, and operational issues are discussed.

The rising complexity of entertainment- and communication components in automobiles requires system solutions which are likely to consist of several separated devices, even in the future. Increasing demands with regard to system diagnostics and electromagnetic interference on the one hand and the necessity to lower system costs on the other force automotive industries to develop concepts avoiding any redundancies and to optimize data links for component interconnections. As the car is a particularly harsh environment for distributed audio-/ video communication systems (limited space, high levels of electromagnetic radiation that interferes with analog signals) fibre optical network solutions can be a suitable way to solve the problem.
