  • Patent number: 8037095
    Abstract: A data accessing method and system. The method includes receiving by a computing system from a first user, a first user profile comprising user preference data associated with the first user. The computing system receives and stores Webcast data associated with a Webcast that has been broadcasted for an entity. The Webcast data comprises audio/video data. The computing system receives from the first user, a first request for access to the first Webcast data. The computing system associates the user preference data with a first set of specified portions of the audio/video data. The computing system retrieves a first portion of audio/video data of the first set of specified portions of the audio/video data. The computing system presents the first portion of audio/video data to the first user.

  • Patent number: 7498842
    Abstract: A level shifter circuit for shifting a voltage level of a logic signal from a first voltage to a second voltage, and a design structure on which the subject circuit reside are provided. An input stage operating in a domain of a first voltage supply includes a first inverter receiving an input signal and providing a first inverted signal. An output voltage level shifting stage operating in a domain of a second voltage supply is coupled to the input stage and providing an output signal having a voltage level corresponding to the second voltage supply domain and a logic value corresponding to the input signal. The level shifter circuit enables voltage level shifting a logic signal from a high to a low operating voltage, or from a low to a high operating voltage. The level shifter circuit enables high frequency operation, providing both fast switching and low capacitance.

  • Patent number: 7482838
    Abstract: A high-speed differential receiver is used between a high voltage domain and a low voltage domain. The high-speed differential receiver includes a common mode differential amplifier coupled to a differential level shifter. The common mode differential amplifier and differential level shifter operates at the high voltage domain. The differential level shifter receives amplified differential signals from the common mode differential amplifier and provides voltage level shifted differential signals applied to a biased differential amplifier operating at the low voltage domain.
