  • Patent number: 11007867
    Abstract: A fuel tank assembly includes a securement structure that may be secured to a fuel tank. The securement structure may stabilize the lower regions of a draw tube and a return tube positioned within the fuel tank such that movement and vibration of the draw and return tubes is reduced during motion of the vehicle to which the fuel tank is secured.

  • Patent number: 10522949
    Abstract: Pin layouts for HSIO require a large number of pins due to isolation requirements. Differential signaling can be used in high speed transmission and reception. A single lane for operation at 6 to 8 Gbps speed typically a total of six to eight pins. At higher speeds, conventional technique to meet isolation requirements is to increase the number of ground pins per lane. With many lanes, the number of pins can become cumbersome. To address such issues, it is proposed to provide pin patterns that leverage differential cancellation to enhance signal isolation so that operation speed can increase while also reducing the number of pins so that the number of pins of a package is less cumbersome.
