Abstract: A fluid delivery device has a syringe barrel-type reservoir with plunger, and plunger driver assembly comprising double-acting, telescoping lead screws that is located behind and outside of the barrel. Simultaneously and counter-rotating sleeve screw and center screw telescope out of a nested configuration of the plunger driver assembly and into the reservoir at a rate of double their individual and equal pitch and lead parameters when the sleeve screw is rotated. A threaded nut and gear anchor disposed on an end of the barrel receive the sleeve screw and the threaded nut causes the sleeve screw to translate and rotate in response to motor operation. A distal end of the center screw can be keyed to a plunger pusher for anti-rotation constraint when the motor is imparting rotation on the threaded nut and sleeve screw.

Abstract: A semitrailer is configured as a mobile presentation enclosure where the semitrailer rests on the ground when detached from a truck which enables individuals to easily access a floor top surface in an interior of the semitrailer by taking one step up onto the floor top surface in the interior of the semitrailer.

Abstract: A method for plasma containment comprises varying the system energy subject to Maxwell's equations, momentum moment equations, and adiabatic equations of state, without imposing a quasi-neutrality condition. In one embodiment, electrons are confined by magnetic forces and ions by internal, electrostatic forces that arise due to charge separation of the two fluids. In one embodiment, input parameters for the energy variation process are selected so as to satisfy a plasma beta parameter condition, thereby reducing the number of control variables by one. The radial scale length for cylindrically symmetric plasmas in one-dimensional equilibrium is characterized by the electron skin depth. Such plasmas can be confined as a high aspect ratio toroid having compact dimensions. Applications of the invention include neutron generation, x-ray generation, and power generation.

Abstract: A distributed messaging method for publishing topical data messages in a communications network can include the steps of receiving in a first message router from a data consumer a request to subscribe to a message topic; responsive to receiving the subscription request, retrieving from a message topic server a location of a second message router communicatively linked to a data publisher able to provide data messages consonant with the requested message topic; establishing an interprocess communications connection between the first and second message routers; and, transmitting data messages from the data publisher over the established interprocess communications link to the data consumer.
