A device, method and system for causing a controlled collapse of cavities formed within liquid droplets wherein a pressurized jet comprising a liquid and nanoparticle material produces droplets from the breakup of the jet stream. The liquid droplets may be irradiated with energy to produce and expand cavities formed within the droplets by irradiation of the nanoparticles contained within the droplets or alternatively, a volatile fluid with or without a metal nanoparticle may form the cavity. The droplets are collided with a target to collapse the cavities within the droplets. The irradiating (if provided) and colliding are timed to enhance implosion energy resulting from the cavities' collapse. The implosion energy and the fuel in the cavity may be used to activate and sustain a fusion reaction or from any other purposes.

System and method for creating liquid droplet impact forced collapse of laser nanoparticle nucleated cavities

A system for synthesizing nanostructures using chemical vapor deposition (CVD) is provided. The system includes a housing, a porous substrate within the housing, and on a downstream surface of the substrate, a plurality of catalyst particles from which nanostructures can be synthesized upon interaction with a reaction gas moving through the porous substrate. Electrodes may be provided to generate an electric field to support the nanostructures during growth. A method for synthesizing extended length nanostructures is also provided. The nanostructures are useful as heat conductors, heat sinks, windings for electric motors, solenoid, transformers, for making fabric, protective armor, as well as other applications.

Systems and methods for synthesis of extended length nanostructures

A device, method and system for causing a controlled collapse of cavities formed within liquid droplets wherein a pressurized jet comprising a liquid and nanoparticle material and possibly fuel produces droplets from the breakup of the jet stream. The liquid droplets are irradiated with energy to produce and expand cavities formed within the droplets by irradiation of the nanoparticles contained within the droplets. The droplets are collided with a target to collapse the cavities within the droplets. The irradiating and colliding are timed to enhance implosion energy resulting from the cavities' collapse. The implosion energy and the fuel in the cavity may be used to activate and sustain a fusion reaction.

A method and apparatus for forming high-speed water droplets takes advantage on a synergy of features disclosed by the present invention including a low Weber number in a chamber in which a liquid stream breaks up into droplets; a reduced break up distance for forming the water droplets by introducing turbulence into the liquid source, thereby providing a unit or tool that is of practical size; accomplishing the generation of high-speed water droplets without using a complex driver; reducing the liquid's surface tension thereby facilitating the creating of near spherical droplets; and maintaining the droplets in form until they strike the surface of a workpiece.

A metal jet cutting system, which includes a jetting heat, a heater and a power source, is used for modifying a workpiece. The jetting head includes a crucible and an inlet for receiving a feed stock of a conductive material. The heater melts the conductive material in the crucible to provide a conductive fluid, which exits the jetting head via an outlet. The power source, which is in electrical communication with the conductive fluid, increases the temperature of the conductive fluid. The conductive fluid is applied to the workpiece to modify the workpiece.

Process and apparatus for cutting or welding a workpiece

A configurable baffle to configure fluid flow through a nozzle. To improve the quality and accuracy of processing apparatus used in the cutting, welding, and heat treating of materials, a self-aligning nozzle includes a configurable baffle. This configurable baffle can be a metallic grid (e.g., a screen) or other type of membrane (e.g., porous, permeable, etc.). During its initial use in the processing apparatus, this configurable baffle is tailored with an energy beam, such as a laser beam or plasma jet, to create an optimal fluid flow velocity profile. When the configurable baffle deteriorates from use, it is easily replaced by another baffle or by using an in situ replacement mechanism. To ensure proper alignment between the nozzle and the energy beam, mating contoured surfaces are used among adjacent components. Threaded surfaces can also be employed to assist in achieving the proper coaxial alignment.

Configurable nozzle baffle apparatus and method

A dynamic variable geometry fitting system with fluid-filled bladders and automatically regulating their volumes to provide a continuously secure fit. This system can vary volume continuously to accommodate natural variation in an amputee's residuum. It makes reliable suction retention of a prosthesis easier for the prosthetist to achieve while reducing the potential for tissue lesions. By maintaining a continuous, secure fit, the amputee's sense of confidence and willingness to use the prosthesis increases.

Methods of use of a portable in-bed exercising machine are provided for strengthening and/or strength maintenance of the musculature and ligaments associated with an extremity. The exercise apparatus employs the principles of closed kinetic chain exercise of the extremity in both concentric and eccentric modes and for isometric, isotonic and isokinetic exercise. Each extremity is engaged separately allowing for bilateral, unilateral and reciprocal motion. As exemplified for lower extremities, force is actively applied to the feet with each lower extremity having the force level continuously adjustable from zero force to a force equal to or greater than body-weight The exercise motions and force applications use the same major muscle groups as functional activities such as standing from a chair, climbing stairs walling, jumping and jogging. Vertical support is provided for the lower extremity to stabilize and control the lower extremity motion within safe limits. Back support is provided for the user to exercise in a supine position. Almost any bed may be integrated with the force producing machine to form the exercise apparatus. The methods of use are adaptable to low gravity environments such as space stations, space shuttles, and other space-like environments.

Disclosed are chromatography methods and matrix geometries which permit high resolution, high productivity separation of mixtures of solutes, particularly biological materials. The method involves passing fluids through specially designed chromatography matrices at high flow rates. The matrices define first and second interconnected sets of pores and a high surface area for solute interaction in fluid communication with the members of the second set of pores. The first and second sets of pores are embodied, for example, as the interstices among particles and throughpores within the particles. The pores are dimensioned such that, at achievable high fluid flow rates, convective flow occurs in both pore sets, and the convective flow rate exceeds the rate of solute diffusion in the second pore set. This approach couples convective and diffusive mass transport to and from the active surface and permits increases in fluid velocity without the normally expected bandspreading.

Perfusive chromatography

A switch mechanism with a safety member for operating a tool or a weapon which reduces the probability of inadvertent operation. The switch mechanism comprises a trigger and a safety member disposed adjacent to the trigger for preventing the trigger from contacting an actuation switch. The safety member is shaped such that when it is positioned in a first position, it prevents the trigger from contacting the switch. In addition, the safety member is shaped such that when the safety member is positioned in a second position, it allows the trigger to contact the actuation switch.
