    摘要: A method, which provides a location context to an online object, includes (a) receiving identification information regarding the online object; (b) in a database, creating a relationship between the online object and a representation of a geographical location; (c) receiving a request for retrieving the relationship from the database based on the identification information or the geographical location; and (d) responding to the request by returning the relationship retrieved from the database. The request may originate from an application program that displays the representation of the geographical location graphically. The online object may correspond to an online business. In some implementations, the online object is unrelated in real life to a community located at the geographical location.

    摘要: The present invention discloses a LPC2468-based MVB-WTB gateway and associated operating methods in the field of train communications. The disclosed network gateway includes a MVB network card and a WTB network card. The WTB network card includes WTB-ARM and a WTB-FPGA module. The MVB network card includes MVB-ARM and MVB-FPGA module. The WTB-ARM module uses a LPC2468 processor to analyze data in the network layer and the data link layer based on gateway protocol. The WTB-FPGA module allows WTB to exchange data with other networks gateways, as well as between the WTB and MVB. The MVB-ARM module is responsible for executing protocols on the network cards. Via data communications on MVB, the MVB-FPGA module collects the process and message data of the MVB equipment, and exchange communication data between WTB within a network gateway. The present invention can increase speed and enhance reliability for communications between gateways.

    摘要: Multilevel converters and space vector modulation operating methods are presented in which fewer than all possible switching states are employed for space vector modulation of rectifier and inverter circuits to promote common mode voltage contribution cancellation or reduction therebetween and by using subsets of possible space vector modulation switching states associated with minimal positive or negative common mode voltages and in some cases using virtual vectors which have zero common mode voltages to eliminate the 3rd order harmonic components in common mode voltage as well as to reduce common mode voltage affects associated with multilevel inverter stages.
