Abstract: A mesoporous, nanocrystalline, metal oxide construct particularly suited for capacitive energy storage that has an architecture with short diffusion path lengths and large surface areas and a method for production are provided. Energy density is substantially increased without compromising the capacitive charge storage kinetics and electrode demonstrates long term cycling stability. Charge storage devices with electrodes using the construct can use three different charge storage mechanisms immersed in an electrolyte: (1) cations can be stored in a thin double layer at the electrode/electrolyte interface (non-faradaic mechanism); (2) cations can interact with the bulk of an electroactive material which then undergoes a redox reaction or phase change, as in conventional batteries (faradaic mechanism); or (3) cations can electrochemically adsorb onto the surface of a material through charge transfer processes (faradaic mechanism).

Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

Abstract: A device for analyzing an analyte in a sample includes a first substrate, a second substrate, a fluidic channel, an inlet port and an outlet port. Each of the first substrate and the second substrate has an inner surface and an outer surface, the inner surface of the first substrate forming, at least in part, the lower wall of the fluidic channel, and the inner surface of the second substrate forming, at least in part, the upper wall of the fluidic channel. The fluidic channel is connected to the inlet port and the outlet port. The fluidic channel includes a reagent region and a detection region, at least a portion of the reagent region being coated with one or more dried reagents. The device further includes a wicking pad located on the outer surface of the second substrate, the wicking pad being positioned at a pre-determined distance from the outlet port.

Abstract: A particle identification system includes: a cartridge for containing a sample with fluorescently labeled particles; illumination for illuminating a region within the cartridge to stimulate emission from particles; imager for generating wavelength-filtered electronic images of the emission within at least one measurement field of the region; and particle identifier for processing the electronic images to determine a superset of particles of interest, and fluorescently labeled particles within the superset based on properties of the particles in the at least one measurement field.

Abstract: A cartridge for detecting a target analyte in a sample includes (a) a capillary channel with a detection region configured for detection of the target analyte, (b) an inlet port configured to hold the sample before entering the capillary channel and including a dried reagents for rehydrating into the sample, the inlet port and the capillary channel being shaped in part by a common structure, and (c) a vent having a frangible seal configured to prevent flow of the sample into the capillary channel until the frangible seal is broken, the capillary channel being airtight between the inlet port and the vent.

Abstract: A method for determining fluorescently labeled particles within a sample in presence of sample movement includes determining spatial shift between sequentially captured first and second images of the sample by using a third image of the sample, wherein the spatial shift is at least partially induced by the sample movement; and spatially correlating events between the first and second images, while accounting for the spatial shift. A method for providing a fluidic assay cartridge with dried reagents includes depositing a plurality of mutually incompatible liquid reagents in a respective plurality of mutually separated areas of the fluidic assay cartridge, and drying the plurality of mutually incompatible liquid reagents to form the dried reagents.

Abstract: A rapid diagnostic system that delivers a panel of serologic assay results using a small amount of blood, serum, or plasma is described. The system includes a disposable cartridge and a reader instrument, based on planar waveguide imaging technology. The cartridge incorporates a microarray of recombinant antigens and antibody controls in a fluidic channel, providing multiple parallel fluorescence assay results for a single sample.

Abstract: This boat docking system allows small or medium size boats to dock under adverse conditions of swift currents and contrary winds with limited crew and no assistance from shore. The invention includes a docking stick to be used from the boat and a small vertical post that is permanently attached to the dock. The docking stick is comprised of a rigid handle with a stiffened loop at one end and a flexible adjustable loop at the other end. As the boat approaches the dock the flexible end of the docking stick is attached to the boat amidships, and the stiffened loop is dropped over the post, or a cleat, on the dock. The boat is then powered slowly forward. The resultant pull on the boat forces it to move sideways towards the dock where it will remain stationary, under power, until securing lines can be attached to the boat.
