20100034003 | Electric Power Generation and Conversion with Controlled Magnetics - A power conversion system comprises: a source of multiphase high frequency alternating current (AC) electrical input power; a high frequency controlled magnetics transformer for each phase of the multiphase high frequency AC input power, with each transformer having a primary winding coupled to its respective phase of the multiphase high frequency AC input power, at least one secondary winding that produces high frequency AC output power and at least one control winding responsive to a direct current (DC) control signal that changes the high frequency output power in proportion to the amplitude of the DC control signal; a power converter that receives the multiphase high frequency AC output power from each high frequency transformer secondary and converts it to system output power without the high frequency AC content; and a system controller responsive to the system output power that produces a DC control signal for each control winding that changes in amplitude in response to changes in a measured parameter of the system output power. | 02-11-2010 |
20100315030 | TORQUE HARMONIC REDUCTION CONTROL FOR SWITCHED RELUCTANCE MACHINES - A controller for a switched reluctance machine (SRM) generates current commands that reduce torque harmonics generated by the SRM. The controller monitors the phase currents and rotor position of the SRM to estimate torque generated by the SRM. The current command signal is modified based on the difference between the torque command and the estimated torque. A multiplier that varies with the monitored torque command is applied to the modified current command to provide a smooth phase-to-phase transition. | 12-16-2010 |
20110031841 | Permanent Magnet Brushless Machine with Magnetic Flux Regulation - A permanent magnet machine (PMM) comprises: a generally cylindrical permanent magnet (PM) rotor that comprises multiple PM rotor poles arranged around a rotor axis of rotation; and a stator with two generally cylindrical and concentric yokes, an inner yoke proximate the PM rotor with associated multiple inner poles and inner armature windings suitable for multiphase alternating current operation that form a PMM magnetic flux circuit, an outer yoke with associated multiple outer poles and outer control windings suitable for connection to a direct current source, with distal ends of the outer poles in contact with the inner yoke to form an external magnetic flux circuit that diverts magnetic flux from the PMM magnetic flux circuit; wherein application of increasing direct current to the outer windings results in increased magnetic reluctance of the external magnetic flux circuit, thereby causing the external magnetic flux circuit to divert less magnetic flux from the PMM magnetic flux circuit. | 02-10-2011 |
20130076035 | MOTOR-GENERATOR TURBOMACHINE STARTER - An exemplary turbomachine starter assembly includes a motor-generator that selectively operates in a motor mode or a generator mode. The motor-generator provides a rotational input to a turbomachine when operating in the motor mode. The motor-generator generates a supply of electrical power when operating in the generator mode. The supply of electrical power is used to power accessories of the turbomachine. | 03-28-2013 |
20130277976 | MULTI-ROTOR GENERATOR - A generator system comprises an inner generator rotor, an outer generator rotor, and a stator. The inner rotor is mounted on the first shaft rotating at a first speed, while the outer rotor is mounted on a second shaft coaxial with the first shaft, and rotating at a second speed different from the first speed. The outer rotor is mounted coaxially with and radially outward of the inner rotor, and the stator is mounted coaxially with and radially outward of the outer rotor. | 10-24-2013 |
20140300440 | INDUCTOR GAP SPACER - An inductor comprises a ferromagnetic or ferrimagnetic core with a reluctance gap, a plurality of conductive windings disposed about the ferromagnetic or ferrimagnetic core, and a spacer. The spacer separates the conductive windings from the ferromagnetic or ferrimagnetic core in the immediate vicinity of the reluctance gap, such that the conductive windings are substantially unaffected by fringing flux from the reluctance gap. | 10-09-2014 |

20090110181 | Administering multiple target ACD systems - Method and system for administering multiple target systems automatic contact distribution (ACD) systems, where corresponding object types in the various target systems may have different schema. A user of the administering system works in a single schema, and translators permit communication between the administering system and the various target systems. | 04-30-2009 |
20090210394 | Enterprise Entity for Use in a Call Center - A call center application program allows a call center administrator to access, view, and edit data across multiple applications used by multiple customer interaction systems of the call center. The application program is adapted to retrieve data from a plurality of different applications and systems, consolidate redundant data, and display the data to a user, enabling a single unified view of resources across call center applications. Changes can be made to the data application program, which in turn propagates the changes to the individual call center applications, eliminating the need for the user to manually change the data in each individual application. | 08-20-2009 |
20100111284 | SYNCHRONIZATION OF MULTIPLE TARGET SYSTEM DATA - A method and apparatus are provided for exchanging configuration information within a call center system between a central server and a plurality of dissimilar contact centers. The method includes the steps of the central server monitoring an contact center of the plurality of dissimilar contact centers for a configuration change message and converting the configuration change between a format of the central server and a format of a subscribing contact center of the plurality of contact centers, where the subscribing contact center is different than the monitored contact center. | 05-06-2010 |
