Abstract: Configurations are described for assisting execution of a percutaneous procedure while protecting the vascular pathway to the target treatment area. One example is directed to an embolic protection system for deploying a device to a distal location across a diseased vessel, the embolic protection system which may include an expandable introducer, an embolic protection device, and a loading sleeve.

Abstract: An RF channelizer comprising: a master laser for generating a reference beam; a splitter for splitting the reference beam into first and second beams; first and second modulator modules for converting the first and second beams into first and second modulated beams; first and second seed tone generators for deriving first and second seed tones; first and second parametric mixers for converting the first and second seed tones into first and second combs; a signal modulator for modulating a received RF signal onto the first comb; first and second optical filters for separating the first and second combs into pluralities of first and second filtered beams with center frequencies corresponding to the second comb lines; and a coherent detection array for selecting, combining, and detecting corresponding pairs from first and second filtered beams providing at the output a contiguous bank of channelized signals covering the bandwidth of the RF signal.

Abstract: An optical domain spectrum analyzer/channelizer employs multicasting of an analog signal onto a wavelength division multiplexing grid, followed by spectral slicing using a periodic optical domain filter. This technique allows for a large number of high resolution channels. Wideband, 100% duty cycle, spectrum analysis or channelization is made possible permitting continuous time wideband spectral monitoring. The instantaneous bandwidth of the spectrum analyzer/channelizer is equal to the full radio frequency bandwidth of the analyzer/channelizer.

Abstract: A system includes an ultraviolet light source, such as light-emitting diodes, disposed between a first ionic grid and a second ionic grid. The first and the second ionic grids have opposite ionic charges and a plurality of silver nanoparticles disposed thereon. The ultraviolet light source is configured to emit, onto the first and the second ionic grids, ultraviolet radiation having a wavelength of between about 100 nm and about 280 nm. A biochemical detector may be located adjacent to the first ionic grid on a side of the first ionic grid opposite the ultraviolet light source. The ultraviolet light source, first ionic grid, and second ionic grid may be located within a housing connected to a gas mask, and a membrane filter may be disposed between the gas mask and housing. The housing may include a power source connected to the ultraviolet light source.

Abstract: A method of liquid phase synthesis of carbon nanotubes in air comprising the steps of making a first liquid phase metal salt catalyst solution of a first predetermined volume; making a carbon source liquid phase solution of a second predetermined volume; ultrasonicating the first metal salt catalyst and the carbon source solutions to de-agglomerate and uniformly disperse their powder form into the solutions; depositing predetermined volumes of droplets of the first metal salt catalyst and the carbon source solutions onto a substrate; drying the first metal salt catalyst and the carbon source solutions on the substrate in an air environment for a predetermined time to form a carbon and catalyst composite; and heating the carbon and catalyst mixture in the air environment for a predetermined temperature and time to form one or more carbon nanotubes.

Abstract: A system includes at least two optical fibers crossing to form a vertice. The optical fibers comprise a core, a cladding surrounding the core, and a conductive coating at least partially surrounding the length of the cladding. A portion of the core of each of the fibers is exposed proximate to the vertice. An optical microsphere whispering gallery mode (WGM) resonator is positioned to cover exposed core portion of each fiber and in contact with the conductive coating of each fiber. The optical fibers may be orthogonal to each other or offset by a non-orthogonal and non-zero angle. The WGM resonator may be positioned between each of the fibers. An optical energy source may be coupled to an end of the optical fibers, with an optical detector coupled to the other end. A voltage source may be connected to the conductive coating of each of the optical fibers.
