  • Loop detection in a communications network
    Publication number: 20070230357
    Abstract: A first node includes ports and a controller to receive a test packet at a first one of the ports. The first node determines whether the received test packet has a destination address that matches one or more predefined addresses associated with a second node. Presence of a loop in a communications network in which the first and second nodes are located is indicated in response to detecting receipt of the test packet containing the matching destination address.

  • Printed circuit board with low noise
    Patent number: 7129419
    Abstract: The present invention relates to a printed circuit board with low noise. A voltage source layer and a ground layer of the printed circuit board are divided into an analog area and a digital area respectively via an isolation line, and adapted to conduct voltage source signal and ground signal respectively. Because the isolation line is an open pattern and a capacitor adapts to position near the opening, the noise and the electro-magnetic parameter of the printed circuit board are reduced.
