Patent number: 7930051Abstract: A method and system for allowing a vehicle dealer and manufacturer to match dealer orders and manufacturing plant shipments easily and equitably are disclosed. The method significantly decreases processing time, saving valuable time, money, and manpower resources. An automated linear expression calculation for determining and balancing vehicle allocation allows for equitable balancing of manufacturing plant orders and efficient optimization. The linear expression calculation may be performed in an iterative series of steps. The linear expression calculation handles a plurality of attribute features, thereby accommodating a plurality of dealer requests and vehicle options. The linear expression calculation creates a matrix representing the plurality of attribute features, and with each iteration the values within the matrix are refined and optimized, with the resulting matrix representing an optimized and balanced allocation of manufacturing plant production orders among a plurality of manufacturing plants.Type: GrantFiled: April 23, 2008Date of Patent: April 19, 2011Assignee: Honda Motor Co., Ltd.Inventors: David B. Adair, James V. Burrell, Charles Chao, Mohan K. Gupta, Melissa Hirota, Patrick Jaillet, Lalit Jain, John Kealoha, III, Ryan K. Kita, Quang N. Mai, Dirk Niemeyer, Nirod Samal, Chung Wang, Flora F.

Patent number: 7729599Abstract: A device and a method are provided for determining the after-run voltage of a direct current motor which is operated via cycled control. In normal operation the direct current motor is controlled via PWM control and a first specifiable pulse/no-pulse ratio. An evaluation unit is provided for determining an after-run voltage variable which is representative of the after-run voltage of the motor. Furthermore, for determining the after-run voltage variable the direct current motor is controlled via a specifiable, variable second pulse/no-pulse ratio.Type: GrantFiled: January 25, 2006Date of Patent: June 1, 2010Assignee: Robert Bosch GmbHInventors: Christoph Emde, Wolfgang Peveling, Gotthilf Koerner, Andreas Schmidtlein, Volker Weeber, Achim Noller, Heiko Bock, Dirk Niemeyer
