  • Patent number: 7654748
    Abstract: A re-terminable, no-crimp ST-type optical connector assembly includes a spring-loaded ferrule holder assembly and a reusable activation system for termination of the assembly. The optical connector can be terminated by a suitable cam activation tool. The connector includes a housing, such as a bayonet, matable to a mating adapter, a backbone retained within a rear of the housing, a ferrule holder provided within the backbone, and a cam provided between the ferrule holder and the backbone. The ferrule holder includes an alignment key exposed to mate with a cam activation tool to lock rotation of the ferrule holder relative to other connector components. The cam includes a cam activation cutout at a front face thereof that mates with a cam activation tool interface to enable rotation of the cam between de-activated and activated positions, the cam activation cutout also receiving the alignment key of the ferrule holder therethrough.

  • Patent number: 7657775
    Abstract: Methods, circuits, and apparatus for changing a frequency of a clock signal provided to a graphics memory while reducing any resulting visual glitch or disturbance on a monitor. A specific embodiment provides multiple clock sources that may be multiplexed or selected to provide a memory clock signal to the graphics memory. The multiplexer switches from providing a first clock source signal as the memory clock signal to providing a second clock source signal as the memory clock signal. The first clock source changes its frequency of operation. After the first clock source settles or stabilizes, the multiplexer switches back to providing the first clock source signal as the memory clock signal.

  • Publication number: 20070266241
    Abstract: A system for preventing successful denial of service attacks comprises a first communication device, a second communication device, and a network. The first and second communication devices establish a communication session via the network. Based on various information, such as a pre-shared secret, one of the communication devices determines a network access filter value and compares this value to at least one data frame in order to authenticate such data frame without committing significant computing resource and any memory space. By updating the network access filter over time, an unauthorized user who discovers the outdated network access filter values is prevented from successfully launching a denial of service attack.
