  • Patent number: 7394569
    Abstract: An improved error-diffusion image processing system and the method thereof adopt the block reading mechanism to replace the row reading mechanism employed in the conventional error-diffusion image processing. This can greatly reduce the memory space required for image processing and increase the operational efficiency. The problem of gaps existing in the block reading mechanism is solved by adding a required error sum (BEsum) in a summed pixel range according to specific position conditions of each block.

  • Patent number: 7034345
    Abstract: A novel architecture of high-power four-quadrant hybrid power modules based on high-current trench gate IGBTs and arrays of low-current wide-bandgap diodes is conceived. The distributed physical layout of high power density wide-bandgap devices improves the cooling inside a fully-sealed module case, thus avoiding excessive internal heat flux build up and high PN junction temperature, and benefiting the converter's reliability and efficiency. The design of multiple-in-one hybrid integrated AC-switch module at high power ratings is enabled by using hybrid AC switch cells and aluminum nitride substrate structure.

  • Patent number: 6989592
    Abstract: A dual-side thermal interface and cooling design of an integrated power module is disclosed which effectively reduces the equivalent thermal impedance on the power module by 20%. This in turn reduces the temperature rise of the junction temperature of the power devices inside the power module by 20% with an equivalent load current. As a consequence the weight and volume associated with the conventional cooling mechanism not employing a dual thermal interface is reduced, thus increasing the ambient operating temperature limit of a power converter in the module.
