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.

A method and system for automatically initiating particular computer system activities in a computer system. Initially, a predetermined list of computer system activities to be initiated is stored within the computer system. Thereafter, the presence of a user within a particular area surrounding the computer system is detected. Next, particular amount of time that has passed since the computer system activities were last processed is determined. The computer system activities contained within the predetermined list of computer system activities are then automatically initiated, in response to detecting the presence of a user within the particular area, if the particular amount of time that has passed since the computer system activities were last processed is greater than a predetermined threshold period, thereby permitting the computer system activities to be initiated without manual user input. The computer system itself may be implemented as a computer workstation or stand-alone personal computer within a distributed computer network. In this case, the predetermined list of computer system activities to be initiated can be stored at a memory location (e.g., memory location at a server or host) within the distributed computer network.

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.

Gallium nitride material transistors and methods associated with the same are provided. The transistors may be used in power applications by amplifying an input signal to produce an output signal having increased power. The transistors may be designed to transmit the majority of the output signal within a specific transmission channel (defined in terms of frequency), while minimizing transmission in adjacent channels. This ability gives the transistors excellent linearity which results in high signal quality and limits errors in transmitted data. The transistors may be designed to achieve low ACPR values (a measure of excellent linearity), while still operating at high drain efficiencies and/or high output powers. Such properties enable the transistors to be used in RF power applications including third generation (3G) power applications based on W-CDMA modulation.

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.

In one aspect, the modulation of air flow into the exhaust is via an electronically controlled feedback loop. In another aspect, the induced air is heated to assure catalyst performance and retard the loss of recoverable heat from the exhaust stream for combined heat and power applications.
