  • Patent number: 10496342
    Abstract: In the coordination of a data conversion server and a storage server which belong to different security domains, a client terminal is able to replace an authorization token for accessing the data conversion server with a temporary URL on the storage server, the client terminal, which is located outside the data exchange server, will be able to issue a temporary URL without authorization, resulting in a file operation which is not intended by the data conversion server being performed. Scopes for allowing a client terminal to access the data conversion server and scopes necessary for the issuance of a temporary URL are separated from each other, and a limitation is imposed so that the scopes for the issuance of a temporary URL can be used only by the data conversion server, thereby enabling secure provision of a temporary URL to an external client terminal.

  • Patent number: 7924912
    Abstract: A method and apparatus for advantageously utilizing the reset state of an RTZ shift register to guarantee proper data alignment at the feedback taps to facilitate decision feedback equalization (DFE) in a unified signaling system. An input data stream is sliced into an even data stream and an odd data stream, whereby the sliced data is compared to a programmable threshold depending upon a detection mode. Each bit of the even data stream is propagated through RTZ latches and each bit of the odd data stream is propagated through RTZ latches. At any given instant in time, a correct portion of the RTZ latch outputs contain zero information, so that each latch output may be summed in a current mode without the need for any intervening logic. The input data stream is summed in current mode with the feedback data and converted to voltage prior to sampling the currently received data bit.

  • Patent number: 7903761
    Abstract: The present invention provides a method and apparatus for correcting direct current (DC) offsets in radio output signals. The invention comprises a radio processor and a baseband processor. During a calibration routine, the baseband processor measures DC offset produced by the radio processor, generates a corresponding DC offset correction value, and writes the correction value to a discrete memory in the radio processor via a serial processor interface. During a subsequent normal receive operation, the radio processor reads the DC offset correction value from memory and feeds it into a into a digital to analog converter to produce an analog signal that in turn is fed into a radio receive path to nullify undesired DC offset.
