  • Patent number: 11940060
    Abstract: The present invention provides a seal ring structure, which comprises a seal ring member. The seal ring member includes a first ring opening on one side and a second ring opening on the other. A periphery of the first ring opening includes a plurality of leak grooves. When the seal ring member and the valve ball squeeze each other, the plurality of leak grooves can reduce the torque required to rotate the valve ball. A leak-groove length of the plurality of leak grooves is smaller than a seal-ring-member length of the seal ring member. The plurality of leak grooves do not penetrate the seal ring member for avoiding leakage of fluid.

  • Publication number: 20230369255
    Abstract: An organic interposer includes interconnect-level dielectric material layers embedding redistribution interconnect structures, at least one dielectric capping layer overlying a topmost interconnect-level dielectric material layer, a bonding-level dielectric layer overlying the at least one dielectric capping layer, and a dual-layer inductor structure, which may include a lower conductive coil embedded within the topmost interconnect-level dielectric material layer, a conductive via structure vertically extending through the at least one dielectric capping layer, and an upper conductive coil embedded within the bonding-level dielectric layer and comprising copper.

  • Publication number: 20070076790
    Abstract: A spare receiver in a CMTS is used to non-invasively test the upstream signal quality of a network without disrupting a subscriber's operations. A modem registered with a receiver on the network is selected as a testing modem. The spare receiver is RF connected to the receiver and the testing modem is tuned to the spare receiver. The testing modem is used to test the signal quality of the network, such as by using a SNR test. The testing modem remains registered with the network during the testing operation. Other modems are prevented from registering with the spare receiver. If other modems attempt to register on the spare receiver, the system overrides their attempts and moves them back to another receiver. The testing modem is returned to its original receiver when testing is completed.
