摘要:
A matrix converter includes a plurality of switches that electrically connect a multi-phase input voltage source to a multi-phase load; and a controller to output pulse-width modulated (PWM) switching signals to control the switches to produce a multi-phase output voltage from the multi-phase input voltage source. The controller outputs the PWM switching signals by modulating a carrier signal with a time-varying signal having a frequency determined from a desired output frequency for the output voltage.

The present invention relates to a method and system for modifying images characterized in that it includes the ability to assign colour intensity values to pixels exposed during image manipulation operations comprising: means for using the color intensity values of remaining pixels in the original image, and means for assigning color values to the exposed pixels that are similar to those of the surrounding pixels so that the exposed regions blends smoothly with the surrounding region. The instant invention also provides a configured computer program product for carrying out the above method.

A system and method for modifying images has an ability to assign color intensity values to pixels exposed during image manipulation operations. The system and method for modifying images comprises means for using the color intensity values of remaining pixels in the original image, and for assigning color values to the exposed pixels that are similar to those of the surrounding pixels so that the exposed regions blends smoothly with the surrounding region. The means for assigning color values assigns the value of color intensity based on the color intensity value function determined at a location of a pixel. The color intensity value function used to assign values to exposed pixels is determined by fitting a function to the known color intensity values of pixels in the boundary regions of the exposed surrounding pixels. The color intensity value function is approximated using energy minimization along with boundary conditions.

摘要:
A method and apparatus for transferring data between a handheld device and a network over a wireless communications link. A datapool manager breaks files into virtual blocks and adds the virtual blocks to a datapool. A communications manager converts the virtual blocks into transportation packets and controls the transfer of the transportation packets between the handheld device and the network. After a transportation packet is transferred, an acknowledgment is returned indicating that the transfer was successful. If the transfer of a file is interrupted, then, upon reestablishing the wireless link, only those transportation packets for which an acknowledgment has not been returned are transferred. To properly reconstruct the file, a pointer indicates the location of each transportation packet in the file. Furthermore, to enable the use of a partially transferred file, a table of information is maintained indicating the validity of the partially transferred file. Transportation packets are identified as instruction packets or data packets. When determining the order of transfer, priority is placed on the transfer of instruction packets.
