Multi-dimensional intelligent sensing systems using sensor array

Two different kinds of multidimensional intelligent sensing systems are described. Both systems utilize a two-dimensional sensor array for invisible objects. These sensor systems may be useful for understanding multidimensional dynamical states. A sensing and visualization system for spatial gas distribution by the use of semiconductor gas sensors is discussed. Gas distribution can be effectively visualized by using a two-dimensional sensor array system. The visualization of a sound wavefront can also be achieved by a wave-propagation model and a 2-D microphone array. The intelligence of these systems gives the visual moving image and global structure of multidimensional phenomena by organizing local information from pointwise multisensors based on a model of the phenomena. These sensing systems may be useful for understanding multidimensional dynamical states.<>
