Abstract: A method of decontaminating a surface includes exposing the surface to germicidal UV light emitted by at least one germicidal UV light source, preferably a light emitting diode (LED), for a continuous exposure period of between 0.05 seconds and 2 seconds; discontinuing the exposure of the surface to the germicidal UV light for a continuous rest period of between 30 seconds and 120 seconds; and repeating steps a. and b. for a total of at least 3 cycles.

Abstract: A method of moving materials comprises: flowing a first fluid in an axial direction, the first fluid characterized by inertial forces dominating viscous forces of the first fluid; flowing a second fluid in the axial direction, the first and second fluids miscible with one another and the first and second fluids having an interface region therebetween; permitting a reaction to create a reaction product in the interface region, the reaction product mitigating flow-disrupting mixing between the first and second fluids.

Abstract: Methods of making a paper product can comprise forming a substrate from a first furnish that comprises a plurality of pulp fibers, at least partially dewatering the substrate, treating a second furnish that comprises a plurality of surface enhanced pulp fibers (SEPF) at least by adding one or more enzymes to the second furnish, and sizing the dewatered substrate at least by depositing the treated second furnish onto at least one of opposing first and second surfaces of the dewatered substrate. The SEPF can have a length weighted average fiber length that is greater than or equal to 0.20 millimeters (mm) and an average hydrodynamic specific surface area that is greater than or equal to 10 square meters per gram (m2/g).

Abstract: Particles are separated from a source viscoplastic fluid by flowing streams of the viscoplastic fluid and a destination fluid in parallel streamed relationship inside a rotating cylindrical annulus by using baffles to introduce each fluid independently at an inlet lower end of the annulus and for separating the upper streams consisting of an un-yielded source and destination flow proximate the radially innermost side of the annulus, a bulk axial flow in a more central region and a yielded layer destination flow adjacent the radial outermost side of the annulus which contains the particles that have separated. Inlet and outlet baffles are provided at each end of the vertically oriented device to maintain the flows discrete on entry and to maintain the separated flows discrete on exit so as to facilitate removal of the component flows from the fractionator.

Abstract: Particles are separated from a source viscoplastic fluid by flowing streams of the viscoplastic fluid and a destination fluid in parallel streamed relationship inside a rotating cylindrical annulus (FIG. 16 (106, 102b) by using baffles (112, 114) to introduce each fluid independently at an inlet lower end of the annulus and for separating the upper streams consisting of an un-yielded source and destination flow proximate the radially innermost side of the annulus, a bulk axial flow in a more central region and a yielded layer destination flow adjacent the radial outermost side of the annulus which contains the particles that have separated. Inlet and outlet baffles are provided at each end of the vertically oriented device to maintain the flows discrete on entry and to maintain the separated flows discrete on exit so as to facilitate removal of the component flows from the fractionator. The flow is maintained as laminar Poiseuille flow by adjusting the flow rates of the source and destination fluids.

Abstract: A combat helmet may be constructed of a composite material with embedded metal plates Inner and outer shells of woven fibers bound with a thermoset or thermoplastic composite may sandwich titanium or other metal plates to form the helmet. The fibers may include aramid and other fibers that may be laid up in multiple layers. The helmet may be composed of multiple flat faces, and the metal plates may be sheet metal components.

Abstract: The present invention is an apparatus and method of manufacture for providing image capturing modules which can be embedded into thin displays (e.g., in laptop computers) while providing for improved image quality. In accordance with several embodiments, a webcam module embedded in a display has multiple positions. A first position (or a “rest” or “park” position) is the position of the webcam module when it is not in use. In this first position of the webcam module, it is in its most compact configuration, and lends itself to integration into a very thin display. In other positions, the webcam module has a more expanded configuration, thus leading to better image quality. Such an expanded configuration leads, amongst other things, to a larger depth of focus. In one embodiment, a stepped PCB is used to provide good image quality while maintaining a compact form factor as well as structural rigidity.
