Abstract: A method and system for sanitizing at least one surface in an area to be sanitized are provided. At least one illumination module is positioned to radiate the at least one surface with sanitizing electromagnetic radiation (SER). A dosimeter is positioned to measure a level of SER emitted by the at least one illumination module or received by the at least one surface. A control module is in communication with the dosimeter to receive the level of SER emitted by the at least one illumination module or received by the at least one surface, determine an appropriate level of SER to be provided to the at least one surface at least partially based on the level of SER emitted or received by the at least one surface, and control the at least one illumination module to radiate the at least one surface with the determined appropriate level of SER.

Abstract: The current invention is directed to micro-stencil devices and methods. A micro-stencil, in accordance with this invention, comprises a patterned stencil membrane formed from a polymeric layer patterned with stencil features preferably having lateral dimensions in a range of 10 micron to 100 nanometers or less. The micro-stencil preferably includes a porous backing membrane coupled to the stencil membrane to control the flow of print fluids, to allow for two-way flow of print fluids and/or curing gases during a printing operation. The stencil membrane is preferably configured to directly print the stencil features onto a suitable print medium surface. The micro-stencil of the instant invention, is preferably utilized for printing structures comprising interconnected layers, such as micro-circuits, and/or structures comprising polymer arrays.
