Abstract: A reactor includes a shell having an input port configured to receive a reaction mixture and an output port configured to discharge a reaction product and a plug within the shell, the sintered plug having a first catalyst configured to transform the reaction mixture into the reaction product, the plug having pores of at least 0.01 micrometers (?m) diameter. A conduit includes a first and second lumen, the first lumen configured to carry a first fluid in a first direction and the second lumen configured to carry a second fluid in a second direction, the first lumen helically twisted relative to the second lumen, and the first lumen configured to conductively transfer thermal energy to the second lumen. A system includes a reactor with a sintered plug and a heat exchanger including a first and a second lumen helically intertwined about an axis.

Abstract: Inflatable restraints or protective systems are addressed. Included among the restraints and systems are inflatable, braided cushions designed to enhance available protection for the torsos of vehicle occupants, particular when a vehicle is subject to a side-impact collision. The (typically unvented) cushions effectively create their own structure and transfer occupant energy from less tolerant to more tolerant areas of the occupants' bodies.

Abstract: An optical device is provided which includes a plurality of optical modules and an alignment compensation module. Each optical module includes an optical component fixedly coupled to a relative reference mount. The relative reference mount is configured to attach to a substrate. A plurality of optical modules mount on the substrate to form the optical device. The alignment compensation module removes residual alignment errors of the optical device.

Abstract: Inflatable devices principally for vehicle occupant protection are addressed. Included among the devices are curtains or other cushions with braided portions along their lower edges designed to form semi-rigid members when deployed. Unlike commercially-available vehicle curtains, inflation occurs from the bottom (where the semi-rigid member is formed) upward. The devices additionally optionally may include inflatable nodes within the curtains or otherwise extending from the cushions.
