Abstract: A device and method are provided for reducing the peak-to-average power ratio of a mobile station's transmit power in a mobile communication system by spreading and modulating the transmission data by a complex spreading sequence. The complex spreading sequence is generated to have a plurality of chips and a phase difference of 90~ between every two successive complex chips in response to each chip of a PN (Pseudo Noise) sequence. The device and method flexibly control the mobile transmit power by limiting its peak-to-average power ratio to a specific range and thus confining the mobile transmit power to a linear characteristic portion in a characteristic curve of a power amplifier. The phase of the complex spreading sequence is prevented from shifting by 180~ (i.e., .pi.) to maintain the mobile transmit power in the linear portion of the power amplifier characteristic curve.

Abstract: The present invention relates to the architecture and use of a computer system optimized for the efficient modeling of graphics. The computer system has a primary processor and a graphics processor. The primary processor has two vector processor units within it, one which is closely connected to central processor unit. Simultaneously performing complex modeling calculations on the first vector processor and CPU, and geometry transformation calculations on the second vector processor, allows for efficient modeling of graphics. Furthermore, the graphics processor is optimized to rapidly switch between data flows from the two vector processors. In addition, the graphics processor is able to render many pixels simultaneously, and has a local memory on the graphics processor chip that acts as a frame buffer, texture buffer, and z buffer. This allows a high fill rate to the frame buffer.

Abstract: A method and apparatus for producing a discrete particle for subsequent analysis (such as mass spectrometry) or manipulation is disclosed. A discrete particle is generated by a particle generator. A net charge is induced onto the particle by an induction electrode. The particle is delivered to a levitation device where it is then electrodynamically levitated. If the particle is a droplet, desolvation will occur, leading to Coloumbic fissioning of the droplet into smaller droplets. The movement of the levitated droplet(s) can be manipulated by an electrode assembly. The droplet(s), and the charge thereon, can be delivered to a mass spectrometer in one aspect of the invention, providing an ion source for mass spectrometry without the detrimental space charge effects of electrospray ionization. techniques. In another aspect of the invention, the levitated particle(s) may be deposited onto a plate for subsequent analysis by matrix assisted laser desorption and ionization mass spectrometry.

Abstract: A clock signal duty cycle control circuit is provided that receives an incoming signal from a clock signal input source and generates an improved output clock signal having an accurately controlled duty cycle. The circuit controls the duty cycle of the output clock signal by comparing the incoming signal to a reference value in a comparator. The reference value is derived from a reference charge stored on a capacitor. The reference charge is built up in the capacitor using the currents from a current source and a current sink, which are controlled using translated output signals from the comparator.

Abstract: Position data and spot data of explanation contents are stored in a spot data database in a center. Preference data of the individual users are stored in a preference data database. Group's preference data of user groups are stored in group's preference data database in the center. When the center extracts each user's present time and present position from data received from the user, it selects spot data on the basis of the user's present time and present position and also preference data and user group's preference data obtained with user ID from the preference data database and the user group's preference data database, and instructs transmission of the selected spot data to the pertinent user's portable data terminal. Thus, it is possible to provide apt data to users even when the users take action patterns different from a usual action pattern.

Title: Method and system for the combination of non-thermal plasma and metal/metal oxide doped y-alumina catalysts for diesel engine exhaust aftertreatment system

Granted: 2009-05-05
Abstract: The present disclosure pertains to a system and method for treatment of oxygen rich exhaust and more specifically to a method and system that combines non-thermal plasma with a metal doped Y-alumina catalyst. Current catalyst systems for the treatment of oxygen rich exhaust are capable of achieving only approximately 7 to 12% NO x reduction as a passive system and only 25-40% reduction when a supplemental hydrocarbon reductant is injected into the exhaust stream. It has been found that treatment of an oxygen rich exhaust initially with a non-thermal plasma and followed by subsequent treatment with a metal doped Y-alumina prepared by the sol gel method is capable of increasing the NO x reduction to a level of approximately 90% in the absence of SO2 and 80% in the presence of 20 ppm of SO2. Especially useful metals have been found to be indium, gallium, and tin.
