C-sense is a company offering intelligent sensors for a variety of applications. The primary goal is change and novelty detection followed by feature extraction to determine and identify objects, and, if needed track these. Using smart sensor technology combined with sensor and data fusion it is possible to quickly find and identifying objects for situation awareness, diagnostics, control, etc. An example is the C-nose is a multi-sensor electronic nose that can be used as a bomb-nose as well as in food control and medical diagnostics. Another application is air born sensors. Small UAV can carry not only cameras for multispectral analysis but also magnetometers, radiation detectors, etc. Our UAV are small but designed for long duration missions. They can be intelligent to map a radioactive cloud after an accident at a nuclear power plant or identify and track a small vessel at sea.
