  • Patent number: 10805129
    Abstract: Vector signaling codes providing guaranteed numbers of transitions per unit transmission interval are described, along with methods and systems for their generation and use. The described architecture may include multiple communications sub-systems, each having its own communications wire group or sub-channel, clock-embedded signaling code, pre- and post-processing stages to guarantee the desired code transition density, and global encoding and decoding stages to first distribute data elements among the sub-systems, and then to reconstitute the received data from its received sub-system elements.

  • Patent number: 10652067
    Abstract: Orthogonal differential vector signaling codes are described which support encoded sub-channels allowing transport of distinct but temporally aligned data and clocking signals over the same transport medium. Embodiments providing enhanced LPDDR interfaces are described which are suitable for implementation in both conventional high-speed CMOS and DRAM integrated circuit processes.

  • Patent number: 10574370
    Abstract: Advanced detectors for vector signaling codes are disclosed which utilize multi-input comparators, generalized on-level slicing, reference generation based on maximum swing, and reference generation based on recent values. Vector signaling codes communicate information as groups of symbols which, when transmitted over multiple communications channels, may be received as mixed sets of symbols from different transmission groups due to propagation time variations between channels. Systems and methods are disclosed which compensate receivers and transmitters for these effects and/or utilize codes having increased immunity to such variations, and circuits are described that efficiently implement their component functions.

  • Publication number: 20190346331
    Abstract: A tub drain overflow test system employs a kit with a connecting pipe with a front cylindrical portion having an inner threading and an intermediate annular flange coaxial with the front cylindrical portion. The front cylindrical portion extends through an overflow hole of a tub so that the annular flange, optionally with a seal ring, abuts the rear surface of the tub wall. A test cap has outer threading that mates with inner threading of the front cylindrical portion. The test cap also has an annular flange and a breakaway test seal with a projecting grip tab. The test cap has an inner lip that provides a catch for inwardly extending tabs on a finishing fixture to robustly attach. The test cap allows the overflow drain to be tested and then a seal portion is removed to provide access to the opening and the finishing fixture is mounted in place.

  • Patent number: 10467177
    Abstract: Systems and methods for an Enhanced High Bandwidth Memory (EHBM) are described, utilizing fewer physical wires than a HBM interface with each wire operating at a much higher signaling rate. The same logical signals and commands of HBM are supported over this higher-speed transport, with the resulting lower wire count and reduced signal density allowing use of lower-cost interconnection such as an organic rather than a silicon interposer between GPU and DRAM stack.

  • Patent number: 10468078
    Abstract: Systems and methods are described for transmitting data over physical channels to provide a high speed, low latency interface such as between a memory controller and memory devices. Controller-side and memory-side embodiments of such channel interfaces are disclosed which require a low pin count and have low power utilization. In some embodiments of the invention, different voltage, current, etc. levels are used for signaling and more than two levels may be used, such as a vector signaling code wherein each wire signal may take on one of four signal values.

  • Patent number: 10301168
    Abstract: A method and device to insure that a particular dispensing package (18) can only be engaged into an appropriate dispensing location (14). Specifically, the package and the dispenser have mating concentric rings (24, 30) (or portions thereof) to prevent engagement and dispensing of an inappropriate product. In one embodiment, the package (18) is provided with one or more concentric ring projections (24) (or portions thereof) and the dispenser (10) is provided with one or more matching concentric ring recesses (30). The projections and the recesses have similar diameters to define a mating set. In some embodiments, the concentric ring projections are placed on a closure (20), such as a cap, of the package. In alternative embodiments, the projections are placed on the dispenser and the recesses are placed on the package.

  • Publication number: 20190137101
    Abstract: A combustor assembly for a gas turbine engine is provided. The combustor assembly includes a liner at least partially defining a combustion chamber and extending between an aft end a forward end generally along an axial direction. The combustor assembly also includes an annular dome including an enclosed surface defining a slot for receipt of the forward end of the liner. A cap is positioned at the forward end of the liner and at least partially positioned within the slot defined by the enclosed surface of the annular dome. The cap includes a surface configured to contact at least one of the enclosed surface of the annular dome and the forward end of the liner. Such a configuration may form a substantially airtight seal between the forward end of the liner and the annular dome despite a relative thermal expansion between the components.
