Abstract: A micro-gas chromatograph column is formed by texturing a channel into a plurality of green-sheet layers, which are then sintered together to form a substantially monolithic structure. A thick-film paste may be added to the channel textured in the green-sheet layers to provide a porous plug sintered in the micro-gas chromatograph column in the substantially monolithic. A thermal conductivity detector is formed in the substantially monolithic structure by depositing a conductive thick-film paste on the surface of one of the green-sheet layers to define a resistor in an exit channel of the micro-gas chromatograph column.

Abstract: A method for fabricating a multilayered structure out of sheets of green-tape without the application of high pressures includes the step of applying an adhesive to the sheets of green-tape. Selection of an adhesive with a polymer that decomposes at a higher temperature than the binder present in the green-tape promotes stability of the interfaces during the firing process and promotes void-free sintering within the interfacial regions.

Abstract: A multilayered microfluidic device having a substantially monolithic structure is formed by sintering together a plurality of green-sheet layers. The substantially monolithic structure has an inlet port for receiving fluid, an outlet port for releasing fluid, and an interconnection between the inlet port and the outlet port. The substantially monolithic structure may also include a variety of components to enable useful interaction with the fluid, such as electrically conductive pathways, heaters, fluid sensors, fluid motion transducers, and optically transmissive portions. The components are preferably fabricated using thick-film or green-sheet technology and are preferably co-fired with and sintered to the green-sheet layers to become integral with the substantially monolithic structure.

Abstract: An airline passenger management system selectively and positively retains passengers within their seats, thereby eliminating potential airborne threats due to terrorists being able to move about the cabin of the aircraft. The system includes a seat belt latch assembly having a mechanism which selectively disables the latch release, thereby preventing the passenger from releasing his/her seat belt latch and restraining the passenger in his/her seat. The system further includes monitoring and control panels, with a monitoring panel in the passenger cabin and a control panel on the flight deck. These panels indicate the status of each passenger position, with the flight deck panel including a belt latch release control for each passenger position. The system provides for selective release of limited numbers of passengers at any one time during flight, and considers the risk level of each passenger according to statistics entered in a database prior to flight.
