  • Patent number: 10191883
    Abstract: An inter-integrated circuit bus arbitration system includes a first master circuit, a second master circuit, an analog switch circuit, an initial state identification circuit, and a selection control circuit. When the first master circuit is initiated to transmit data, the initial state identification circuit generates a first initial pulse signal. When the second master circuit is initiated to transmit data, the initial state identification circuit generates a second initial pulse signal. If the first initial pulse signal leads the second initial pulse signal, the selection control circuit generates a first control signal to make the analog switch circuit establish electrical connections between the first master circuit and an external data line and an external clock line when receiving the first control signal.

  • Patent number: 7086458
    Abstract: A heat sink module includes a heat dissipation pad. The heat dissipation pad is flexible and has a cambered shape, and is pressed to become a flat plate when disposed between the heat sink module and a CPU.
