A wave front control system (

Using a mechanical shaker test the shear wavespeed in a plate is estimated by applying a cyclical point force to the plate, measuring normal velocity of waves caused by the force, transforming temporal domain measurements with a Fourier transform into a frequency domain, transforming spatial domain measurements into a {kx,ky} wavevector domain spectra using Fourier transforms, determining propagation wavenumbers for given Lamb waves from peaks within the {kx,ky} spectra, and determining shear wavespeed by applying a Newton-Raphson gradient method using the propagation wavenumbers to Raleigh-La

A gain medium and an interband cascade laser, having the gain medium are presented.

A compact solid state laser that generates multiple wavelengths and multiple beams that are parallel, i.e., bore-sighted relative to each other, is disclosed. Each of the multiple laser beams can be at a different wavelength, pulse energy, pulse length, repetition rate and average power. Each of the laser beams can be turned on or off independently. The laser is comprised of an optically segmented gain section, common laser resonator with common surface segmented cavity mirrors, optically segmented pump laser, and different intra-cavity elements in each laser segment.

Systems and methods for a facemask wearer to view high resolution, high data content, color imagery are provided. A display using organic light emitting diode (OLED) micro-displays provides 800

A sheath flow system having a channel with at least one fluid transporting structure located in the top and bottom surfaces situated so as to transport the sheath fluid laterally across the channel to provide sheath fluid fully surrounding the core solution. At the point of introduction into the channel, the sheath fluid and core solutions flow side by side within the channel or the core solution may be bounded on either side by the sheath fluid. The system is functional over a broad channel size range and with liquids of high or low viscosity.

Multiple personal computers are each situated aboard its own ship and are each communicatively connected to an electronic depository of information for purposes of effecting real time management of engines and other shipboard machinery. Information is electronically communicated back and forth between each onboard computer and the electronic depository, such as via File Transfer Protocol (FTP), e-mail or compact disk (CD).

A ranging system for use with a projectile launching device is provided. The ranging system includes an alignment marker visible with an optical sight device. The position of the alignment marker is adjusted based at least on a determined range to a target.

The present invention provides a system and method for controlling resuscitation in a patient. In at least one embodiment, the invention includes a fluid rate measurer, a controller electrically coupled to the fluid rate measurer, and a pump. The controller is adapted to receive signals from a physiological monitor and controls the pump.

In the invention, a collection device includes a flow through micro scale plate arranged to collect analyte. The plate includes holes, and sorbent coating on contact surfaces of the plate. The holes pass analyte fluid flow, for example analyte vapor so that fluid flow for collection may be generally perpendicular to the sorbent plate. Preferred embodiment plates include an integrated heater trace. In preferred embodiments, a high substantially perpendicular flow is used for collection and concentration, and during desorption and delivery a low substantially parallel flow is used.
