Superalloy laser cladding with surface topology energy transfer compensation
ActiveUS20140072438A1Without degrading structural propertyUniform weldingTurbinesMechanical working/deformationTurbine bladeEnergy transfer rate
A superalloy substrate, such as a turbine blade or vane, is fabricated or repaired by laser beam welding to clad one or more layers on the substrate. Laser optical energy is transferred to the welding filler material and underlying substrate to assure filler melting and adequate substrate surface wetting for good fusion. Energy transfer is maintained below a level that jeopardizes substrate thermal degradation. Optical energy transfer to the filler and substrate is maintained uniformly as the laser beam and substrate are moved relative to each other along a translation path by varying the energy transfer rate to compensate for localized substrate topology variations.

Self-Heating Chemical System for Sustained Modulation of Temperature
InactiveUS20070289720A1Easy to adjustBiofuelsWaste based fuelElectrical conductorChemical transformation
A self-heating chemical system using one or more primary components for exothermic reactions (such as calcium oxide), one or more porous components that can serve as a heat sink and conductor of heat as well as under going chemical transformations that release heat (zeolite), a weak acid (citric acid) for sustained modulation of temperature and pH. Exothermic reactions, mixing of some chemicals, sorption of certain chemicals, phase changes in chemicals, and dissolution of some chemicals in solvents release heat during these operations. The rate of heat generation coupled with mass and energy transfer rates to or from system(s) allows modulation of the temperature of systems. The modulation can be further enhanced by controlled release and availability of some of the components. This method provides with a class of self-heating product applications and focuses on the modulation of temperature through sequestering of reactions with different rates, heat release through dissolution, heat release through mixing, heat release through sorption, heat release through phase change as well as controlling mass and heat transfer rates.

Donor-acceptor distance distribution measuring method based on fluorescence correlation spectroscopy
ActiveCN103983623AAccurate measurementAvoid measurement failuresFluorescence/phosphorescenceSelf correlationLaser scanning
The invention discloses a donor-acceptor distance distribution measuring method based on fluorescence correlation spectroscopy. Fluorescent labeled living cells of donors and acceptors are subjected to a selective donor excitation operation through a fluorescence correlation spectroscopy module of a laser scanning confocal microscope in different laser power. A correlation card acquires photon number fluctuation signals of a donor channel and an acceptor channel to form a self-correlation curve. Energy transfer rate and energy transfer efficiency can be calculated through triplet state analysis of the self-correlation curve of the acceptors. In addition, triplet state distribution of the energy transfer rate and the energy transfer efficiency can be inverted from the self-correlation curve of the triplet state of the acceptors through a maximum entropy algorithm so that donor-to-acceptor distance distribution can be calculated. A fluorescence correlation spectrum analysis method itself is an excellent technology of measuring concentration of a dilute solution, so that the measuring method can be used for measuring donor-acceptor non-paired fluorescence resonance energy transfer efficiency and donor-acceptor non-paired distance distribution after integration items of overlap items of the spectrum being corrected with respect to the donor-acceptor concentration proportion.

Method and apparatus for describing and simulating complex systems
InactiveUS20050273297A1Computation using non-denominational number representationDesign optimisation/simulationEntropy fluxEnergy balanced
A method for description and simulation based on organizing data into maps of invariants, the invariants being points of energy balance in a system of interest which is either in a stationary state or in a transitory disturbed state. The method includes identifying invariants in the system of interest by identifying primary sources and sinks of energy, identifying secondary energy sources and sinks coupled to the primary sources and sinks, and coupling all such sources and sinks into a network of transformations organized around nodes of those sources and sinks corresponding to the invariants, each of the nodes being characterized by a locally defined principle of balanced self-organization in a system with both a conservation law and energy dissipation. Such a system becomes “organized” upon achievement of a critical rate of entropy flux into the environment. Associated with each invariant are response rates related to energy transfer rates into and out of the invariants. The invariants are mathematically similar to the critical point found in equilbrium systems that undergo second order phase transitions.
