Abstract: A printed circuit board assembly for coupling a plurality of surge protectors to multi-line communication cables includes a multi-layer printed circuit board, to which has been mounted at least two cable connectors, having multiple female sockets for receiving standard surge protector modules. The multi-layer printed circuit board includes traces on multiple layers in a manner that a unique signal path exists between each lead in each connector and a predetermined one of the plurality of sockets for receiving surge protector modules. The traces having a width and a copper content sufficient to carry large current surges from induced power signals, by way of example, from a lightning strike, without breaking down.

Abstract: A cargo inspection apparatus for the inspection of an analyte carried by a medium is disclosed. The apparatus includes a housing having an inlet allowing for entry of the medium and an outlet allowing for exit of the medium, and an adsorber disposed within the housing in fluid communication with the medium flow from the inlet to the outlet, the adsorber includes a substrate having disposed thereon a nanoparticle film. The nanoparticle film has nanoparticles having an average particle size of equal to or less than about 500 nanometers.

Abstract: A method for compensating for torque ripple in pulse width modulated machines including providing damping for transient disturbances utilizing a fixed feedback controller and rejecting steady disturbances utilizing an adaptive controller.
