摘要:
The present invention relates to a Wet Electrostatic Precipitator Air (WEPA) Purifier and purification method capable of stand-alone operation as the principal air purification system, particularly in military applications. This system is intended to supply small military units within a temporary structure clean, threat-free fresh air for periods up to 12 months without maintenance. The WEPA Purifier is configured to remove and sterilize biological threat particles from an airflow, and further remove and sequester radioactive particulates, thus allowing them to be safely removed at normal maintenance periods. The WEPA Purifier includes a wet electrostatic precipitator filtration element in which particles are charged and collected by a capturing solution flowing over an attracting electrode collection plate. The water is returned by gravity to a reservoir where it is disinfected and captured particles retained in a small, low maintenance, regenerative liquid filter.

An apparatus for airborne particle sorting is provided comprising a charging system adapted for applying an electrostatic charge to the particles, such that particles of at least a first group are deflected to a greater extent than particles of a second group are deflected. A focusing system is adapted for electrostatically focusing substantially at least the particles of the first group into a focused stream that is narrower than the input air stream. A deposition system is adapted for substantially depositing the particles of the first group from the focused stream upon a target surface, where the target surface may be transported to an analysis system capable of analyzing the particles deposited thereon.

Embodiments of an apparatus for concentrating and collecting airborne particles (e.g., biological aerosols) from an air sample include an inlet adapted for receiving the air sample (e.g., from an external or surrounding environment), a first diffuser coupled to the inlet and adapted to concentrate the airborne particles into a particle flow, and at least a second diffuser coupled to the first diffuser in a cascaded configuration and adapted to further concentrate the particle flow.

A self-adjusting pliers-type crimping tool includes a crimping arrangement having movable and fixed levers that are pivotally displaced from an open condition toward a fully closed condition, thereby to generate a first crimping force for crimping an electrical contact upon a bare conductor. When the levers are at an intermediate position, a predetermined compensating energy from a caged spring assembly is released and is applied to the crimping arrangement to complete the crimping process. The spring assembly may comprise a stack of spring washers, a helical spring arrangement, or a stack of resilient elastomeric blocks.

A fiber optic arrangement includes a primary strand, a plurality of secondary connection strands, each of which is coupled to the primary strand at a notch. Tight buffer optical fibers are attached, one at the end of each of the secondary connection strands.
摘要:
An assembly of fiber optic elements includes at least two subunits, each of which has at least one fiber optic unit and a flat binder wrapped over the subunits into an arrangement. The at least two subunits are stranded in a S-Z arrangement at a first lay length and the binder is stranded over the subunits in a uni-directional helical lay at a second lay length. The payoff tension and the first lay length of the subunits, combined with a payoff tension and the second lay length of the binder are simultaneously sufficient to hold the subunits within the arrangement, while being loose enough to allow a single subunit to be removed without destroying the arrangement.

A micro-optical element includes a support substrate, a micro-optical lens in a cured replication material on a first surface of the support substrate, and an opaque material aligned with and overlapping the micro-optical lens along a vertical direction.
摘要:
A fiber optic cable is provided having a at least one fiber element, a layer of aramid strength members, and a jacket disposed over said layer of aramid strength members. The layer of aramid strength members is wound at a lay length that is equal to or lesser than a predetermined bend radius.
