Abstract: Embodiments of an apparatus for collecting biological aerosols from an air sample include a hollow tube adapted for pumping a liquid through an interior volume to an outer surface and a collection surface disposed on the outer surface and adapted for collecting the airborne particles from the surrounding air sample. Collection efficiency is enhanced by a charging mechanism that applies a charge to the airborne particles such that the airborne particles are deflected toward the collection surface. Embodiments of operation for the apparatus include the steps of providing the air sample, directing the air sample toward the hollow tube, and applying a charge to the airborne particles such that the airborne particles deposit on the collection surface/outer surface of said hollow tube.

Abstract: 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.

Abstract: An inexpensive, robust plasma discharge emitter that repeatably creates a patterned charge on a substrate (122). To facilitate highly accurate charge deposition, each emitter (100) contains a plasma well (114) for confining the plasma within the emitter (100). Additionally, a plurality of emitters are arranged in an array to provide a practical charge patterning device. Furthermore, to fabricate an emitter or an array of emitters, a relatively low-cost, repeatable method of fabrication is used that relies upon conventional integrated circuit fabrication techniques.

Abstract: The invention is directed to a corona charging device having a powder feed with an outlet. The device has an internal charging cavity having an inlet and a charged powder outlet. The powder feed outlet is positioned at the internal charging cavity inlet. The device is adapted to guide a powder stream downstream from the powder feed outlet to the charged powder outlet. The device also includes a corona charger having one or more projections positioned and adapted to facilitate a corona ion flow from the projections and intersecting the powder stream. The device also includes a rotating ground electrode adapted to be charged or grounded to attract the corona flow from the projections, and to rotate segments of the ground electrode between the internal charging cavity and a ground electrode cleaner.
