  • Patent number: 9191071
    Abstract: A broadband power line network device includes a printed circuit board, a power converter, a network control chip, a network connector, and an Ethernet signal coupling device. The printed circuit board includes a primary layout region and a secondary layout region. The primary layout region and the secondary layout region are separated from each other by a first distance. The power converter includes a pair of power-receiving terminals for receiving an AC voltage, thereby converting the AC voltage into a DC voltage. The network control chip is disposed on the primary layout region for receiving the DC voltage. The network connector is disposed on the secondary layout region for transmitting or receiving an external network signal. The Ethernet signal coupling device is arranged between the primary layout region and the secondary layout region.

  • Patent number: 7750495
    Abstract: A power line adapter and its controlling method to be operated in a power-saving mode are disclosed. The power line adapter includes a power-transmitting module for generating a DC supply voltage and a data-transmitting module for transmitting data. Furthermore, the data-transmitting module at least includes a power line communication circuit and an Ethernet physical layer transceiver. The controlling method comprises steps of: monitoring a link signal generated by the Ethernet physical layer transceiver when the power line adapter is operated in an active mode; and, disconnecting the DC supply voltage to the power line communication circuit and entering the power-saving mode if the link signal indicates a disconnection over a first time period.
