Abstract: A wound treatment system includes a patch, first and second fluid reservoirs, an electrokinetic pump assembly, and a controller. The patch is configured to enclose a wound area and includes an inlet and an outlet. The first fluid reservoir is fluidically connected to the inlet and the second fluid reservoir is fluidically connected to the outlet. The electrokinetic pump assembly is configured to pump a first treatment fluid from the first fluid reservoir into the patch through the inlet and to pump fluid from the patch through the outlet and into the second fluid reservoir. The controller is configured to operate the electrokinetic pump assembly and to include an electronic memory containing computer readable instructions for operating the electrokinetic pump assembly to perform a wound therapy protocol in the wound area.

Abstract: A method of controlling the output of an electrokinetic pump to deliver a target stroke volume includes applying a pump drive signal to the electrokinetic pump for a pump stroke time duration and then determining a volume of a delivery fluid pumped. Then, comparing the volume of the delivery fluid pumped to the target stroke volume; generate a new time interval for applying the pump drive signal. Then apply the pump drive signal to the electrokinetic pump for the new time interval. A system for delivery of fluid includes an electrokinetic pump under the control of an electronic controller. The electronic controller contains computer readable instructions to determine an output of the electrokinetic pump and then generate a stroke time delivery adjustment for precise pumping schemes.

Abstract: An electrokinetic system includes a first electrokinetic pump, a second electrokinetic pump, a reservoir having delivery fluid therein, and a controller. The first electrokinetic pump is configured to provide a first range of flow rates. The second electrokinetic pump is configured to provide a second range of flow rates. The second range includes flow rates that are greater than the flow rates of the first range. The reservoir is fluidically attached to the first electrokinetic pump and the second electrokinetic pump. The controller is configured to apply voltage to one of the first or second electrokinetic pumps and then apply voltage to the other of the first or second electrokinetic pumps so as to vary the flow rate range of delivery fluid pump from the reservoir.

Abstract: An element support and thermal control arrangement for an active array antenna, preferably modular, using line-replaceable units (LRUs), includes a radiating-side liquid-cooled cold plate lying parallel with a liquid-cooled TR coldplate. Antenna elements are supported and cooled by the radiating cold plate, and a beamformer lies between the radiating and TR coldplates. A plurality of column coldplates are attached to the rear of the TR coldplate and define bays or volumes in which power LRUs can be fitted in thermal communication with the TR coldplate, the column coldplates, or both.

Abstract: A substantially water-free creme having from about 20% to about 50% of a rapidly melting confectionery fat and 50% to about 80% of a carbohydrate is disclosed. This creme has a disordering temperature of between 80.degree. F. and less than 102.degree. F. and a melt rate of 15 seconds to 75 seconds at 92.degree. F. It has a back extrusion force of from about 0.3 to about 6 lbs at 70.degree. F. Disordering temperature relates to the temperature at which the creme and saliva mixture forms a water-continuous phase. The back extrusion force is a measure of the apparent viscosity of the creme. The creme's viscosity remains stable over a broad temperature range.

Abstract: A material transporting device is disclosed wherein material is pneumatically moved along a louvered surface and converged to exit from the device in a narrowed pattern. Use of the device is particularly directed to rapid handling of scrap web material.

Abstract: A printed circuit board is disclosed which comprises a metal substrate having a first coating thereon and through holes through said coating and substrate with non-linear, undercut walls and a dielectric film coating over said first coating and said non-linear, undercut walls of said through hole. Electrical circuitry is then formed on the dielectric coat in conjunction with the through hole.

Abstract: A powder coating composition is disclosed. The composition comprises at least one 1, 2 epoxy compound combined with a functionally terminated elastomer and a curing agent mixture. The curing agent mixture comprises an imidazoline derivative combined with an adduct of (a) a polyhydroxyl compound and (b) a diglycidyl ether of the polyhydroxyl compound, where reactant (b) is present in a less than equimolar amount to reactant (a).

Abstract: A method of fabricating a printed circuit board is disclosed. The method comprises forming a patterned etch resist layer on a metal substrate and selectively etching the substrate to form a through hole with non-linear undercut walls. The etched metal substrate having the resist layer thereon is then coated with a dielectric powder to form a dielectric coat on the substrate having a sufficient through hole edge coverage.
