  • Patent number: 7513298
    Abstract: The present invention is to provide a cooling element for eliminating electromagnetic noise, which is formed by bending a plate into a symmetric structure symmetrically comprising a contact part being in connect with an electronic component to absorb heat and noise radiated therefrom; an extension part having one end connected with said contact part to absorb heat and noise from said contact part; and a dissipation part connected with the other end of said extension part to absorb heat and noise from said extension part; wherein the noises absorbed by the cooling element are transmitted along the paths among the contact part, extension part and the dissipation part, and are mutually offset with each other in accordance with the symmetric structure thereof.

  • Patent number: 6754730
    Abstract: An intelligent apparatus comprises a master module and a plurality of slave modules each having a CPU, a control circuit and an associated software, wherein each of the slave modules is in communication with the master module, and the CPU of the master module may control the CPUs of the slave modules respectively to form a single system. When the master module detects that a monitoring device coupled to a single user I/O interface installed in the apparatus is performing network monitoring and management with respect to a certain module, the CPU of the master module may transfer an access right of the user I/O interface to the certain module by closing or opening switches installed in the master modules enabling the certain module to receive the access signal from the user I/O interface by closing a switch thereof.

  • Patent number: 6052805
    Abstract: A dual speed hub includes a CPU, two hubs of different transmission speeds, two MACs (media access controls), and a switch, wherein the CPU periodically sends a test packet in proper order through one MAC, one hub, the switch and the other hub to the other MAC, then checks the receiving condition and the content of the returned test packet, then determines the normality of the function of the switch subject to the receiving condition and the content of the returned test packet, and then provides a warning signal to a network management system when the switch is judged abnormal, informing the network manager to repair the switch.
