Hydrocarbon combustion power generation system with CO2 sequestration
InactiveUS7043920B2Eliminate needReduce electricity demandReciprocating combination enginesSolidificationAtmospheric airOxygen
A low or no pollution engine is provided for delivering power for vehicles or other power applications. The engine has an air inlet which collects air from a surrounding environment. At least a portion of the nitrogen in the air is removed. The remaining gas is primarily oxygen, which is then routed to a gas generator. The gas generator has inputs for the oxygen and a hydrocarbon fuel. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide. The combustion products are then expanded through a power generating device, such as a turbine or piston expander to deliver output power for operation of a vehicle or other power uses. The combustion products are then passed through a condenser where the steam is condensed and the carbon dioxide is collected or discharged. A portion of the water is routed back to the gas generator. The carbon dioxide is compressed and delivered to a terrestrial formation from which return of the CO2 into the atmosphere is inhibited.

An integrated voltage / current / power regulator / switch (VCPRS) system and method are disclosed in which regulator / switch circuitry is vertically integrated on top of an existing integrated circuit. The present invention does not require additional integrated circuit chip area for the regulator pass device as is required in the prior art, and by virtue of its construction provides a significantly reduced on-resistance as compared to all prior art implementations. The present invention both stabilizes the power supply for large area integrated circuits and permits individual areas of the integrated circuit to have switched power capability, a highly desirable feature in low power and battery power applications. The present invention permits an increase in the power supply rejection ratio (PSRR) for digital, analog, and especially mixed-signal integrated circuit designs by permitting various circuit blocks to have localized power regulation that is obtained from a common power supply plane within the integrated circuit framework. Finally, the present invention appears to be the only economically practical method of addressing the power supply regulation requirements of modern and future integrated microprocessor designs.

Arc detection and handling in radio frequency power applications
ActiveUS7305311B2High sensitivityQuality improvementInput/output for user-computer interactionElectric devicesPower applicationEngineering
A radio frequency power delivery system comprises an RF power generator, arc detection circuitry, and control logic responsive to the arc detection circuitry. A dynamic boundary is computed about the measured value of a parameter representative of or related to the power transferred from the power generator to a load. A subsequently measured value of the parameter that exceeds the computed dynamic boundary of the parameter indicates detection of an arc. Upon detection of an arc, power delivery from the generator is interrupted or adjusted, or other action is taken, until the arc is extinguished. By employing dynamic computation of arc detection boundaries, the invention allows for arc handling in RF power deliver systems regardless of whether the system has reached a stable power delivery condition.

Solid oxide MEMS-based fuel cells
A micro-electro-mechanical systems (MEMS) based thin-film fuel cells for electrical power applications. The MEMS-based fuel cell may be of a solid oxide type (SOFC), a solid polymer type (SPFC), or a proton exchange membrane type (PEMFC), and each fuel cell basically consists of an anode and a cathode separated by an electrolyte layer. The electrolyte layer can consist of either a solid oxide or solid polymer material, or proton exchange membrane electrolyte materials may be used. Additionally catalyst layers can also separate the electrodes (cathode and anode) from the electrolyte. Gas manifolds are utilized to transport the fuel and oxidant to each cell and provide a path for exhaust gases. The electrical current generated from each cell is drawn away with an interconnect and support structure integrated with the gas manifold. The fuel cells utilize integrated resistive heaters for efficient heating of the materials. By combining MEMS technology with thin-film deposition technology, thin-film fuel cells having microflow channels and full-integrated circuitry can be produced that will lower the operating temperature an will yield an order of magnitude greater power density than the currently known fuel cells.
