Patents by Inventor Ahmed Elasser

Ahmed Elasser has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6253115
    Abstract: A system for implementing a design for six sigma process having a plurality of sub-processes each having a plurality of sub-steps. The system includes an independent main application for implementing the design for six sigma process. A series of independent sub-process applications each implements one sub-process of the design for six sigma process. A tool library containing a plurality of executable tools is accessible by the main application and sub-process applications to access and execute the plurality of executable tools. A communications path interconnects the main application, the sub-process applications, and the tool library.

  • Patent number: 6239466
    Abstract: An IGBT is optimized for ZVS operation, thereby significantly reducing switching losses during ZVS operation. In effect, the IGBT is optimized to operate as a MOSFET with a very small bipolar transistor component. Switching losses are reduced by reducing the number of minority carriers injected into the device during conduction. Additionally, this ZVS IGBT structure allows for a small increase in stored charge as the operating temperature is increased, allowing the device to operate at higher temperatures with relatively low switching losses.
