| 20090044661 | METHODS AND APPARATUS FOR THE PRODUCTION OF GROUP IV NANOPARTICLES IN A FLOW-THROUGH PLASMA REACTOR - A plasma processing apparatus for producing a set of Group IV semiconductor nanoparticles from a precursor gas is disclosed. The apparatus includes an outer dielectric tube, the outer tube including an outer tube inner surface and an outer tube outer surface, wherein the outer tube inner surface has an outer tube inner surface etching rate. The apparatus also includes an inner dielectric tube, the inner dielectric tube including an inner tube outer surface, wherein the outer tube inner surface and the inner tube outer surface define an annular channel, and further wherein the inner tube outer surface has an inner tube outer surface etching rate. The apparatus further includes a first outer electrode, the first outer electrode having a first outer electrode inner surface disposed on the outer tube outer surface. The apparatus also includes a first central electrode, the first central electrode being disposed inside the inner dielectric tube, the first central electrode further configured to be coupled to the first outer electrode when a first RF energy source is applied to one of the first outer electrode and the first central electrode; and a first reaction zone defined between the first outer electrode and the central electrode. | 02-19-2009 |

| 20080272715 | Position detection and external driver multiplexing system for DC motors - A system and method is provided for improved monitoring and controlling of mechanically commutated DC motors. The system and method include DC motors, pulse-count driver circuitry for driving the motors, motor position sensing circuitry, and motor control circuitry. The system and method provide for improved motor current waveform sensing that is able to effectively reject false brake pulses, avoid erroneous processing due to fluctuating battery voltage levels, and reduce the sensitivity to variations in motor current signals due to dynamic motor load, manufacturing variation, system aging, temperature, brush bounce, EMI, and other factors. The system and method also include an improved ability to multiplex additional external motor drivers to the motor control circuitry, select between sequential and simultaneous drive modes using an SPI bit, and monitor the system controller for an error condition and simultaneously driver motors in response to the error condition. | 11-06-2008 |

| 20100030407 | SYSTEM AND METHOD FOR AUTOMATICALLY CONTROLLING TAKE-OFF THRUST IN AN AIRCRAFT - A system and method for enabling a flight management computer (FMC) on a jet aircraft to automatically select the proper take-off thrust to use for a specific aircraft operating at a specific airport, and using a specific runway. A Model/Engine Database (MEDB) is created that assigns a specific aircraft configuration code to the aircraft, based on the model, engine and other factors specific to the aircraft. The aircraft configuration code is used by the FMC to query an Airport/Runway lookup table database that is loaded into the FMC. The Airport/Runway lookup table database provides a take-off thrust code indicating the take-off thrust to be used for the aircraft, based on the airport it is about to depart from, and the specific runway that it is assigned to use. The FMC uses the take-off thrust code to automatically select a specific take-off thrust to be used during the take-off phase of flight. | 02-04-2010 |
| 20110093141 | SYSTEM AND METHOD FOR AUTOMATICALLY CONTROLLING TAKE-OFF THRUST IN AN AIRCRAFT - A method for automatically selecting a take-off thrust setting for an engine of a jet powered mobile platform that has a flight management computer (FMC) that makes use of a configuration code. The configuration code is provided from a first set of information relating to operational parameters of the mobile platform. A database in communication with the FMC stores information pertaining to different locations from which a take-off operation can be performed. The FMC accesses the configuration code and the database to determine a take-off thrust setting to apply during the take-off operation at a specified one of the locations. The FMC also determines if an operator has overridden an automatic selection of the take-off thrust. | 04-21-2011 |
