Abstract: Integrated particle capture and detection devices include a microimpactor system for capturing particles or other materials from a fluid stream. The captured materials are subject to in situ analysis, inactivation or chemical reactions. The devices are particularly suitable as air purification devices or personal protection devices, where the air is possibly contaminated with pathogenic or toxic materials. The device can indicate the presence of these materials, or can be used to deactivate them and thus render the air safe for breathing.

Abstract: A interleaved channeless gate array architecture for fabricating very large scale integration circuits created in a gate array comprises a plurality of rows or columns of basic cells wherein each of the cells includes a pair arrangement of complementary channel MOS transistors formed in adjacently disposed different conductivity type diffusion regions. A gate electrode structure for the basic cells comprises a pair of comb-shaped gate electrodes each having a plurality of parallel spatially disposed legs. Gate electrode pairs are formed over each of the basic cells in opposite opposed relation with their legs alternately interleaved relative to each other.
