  • Patent number: 9008215
    Abstract: Methods, systems, and computer readable media for asymmetric multimode interconnect (MMI) are disclosed. According to one aspect, a system for receiver-side asymmetric MMI includes a receiver that receives binary-encoded input signals from a multichannel interconnect, encodes the received binary-encoded signals according to a multimode encoding equation to produce multimode-encoded signals having voltage levels according to the multimode encoding equation, adjusts the timing of the multimode-encoded signals to compensate for multichannel interconnect channel delays to produce delay-adjusted multimode-encoded signals, and decodes the delay-adjusted multimode-encoded signals according to a multimode decoding equation to produce binary-encoded output signals.

  • Publication number: 20150059667
    Abstract: An oil supply device includes a plurality of hollow cam shafts, cam shaft journals, and a shaft side path. The hollow cam shafts have through holes that pass in a longitudinal direction from interior to exterior thereof. The cam shaft journals are provided on every position at which the through holes are formed. Each of the cam shaft journals has a path connected with an associated through hole and is coupled with a cylinder head. The shaft side path is formed to supply oil into each hollow cam shaft after the oil sequentially passing from an oil pump through an associated cam shaft journal and an associated through hole.

  • Publication number: 20140167335
    Abstract: Disclosed herein is a method of manufacturing a coil, including: preparing a mold having vertically movable fixing pins disposed therein and slidable left and right sidewalls; seating a magnetic plate on an inner bottom of the mold; loading the coil on the magnetic plate so that lead parts of the coil are disposed between the fixing pins and the sidewalls of the mold; sliding the left and right sidewalls of the mold into the mold to closely adhere the lead parts of the coil to the fixing pins; filling a magnetic slurry in the mold and primarily pressing the magnetic slurry; and lowering the fixing pins to perform secondary pressing, in order to prevent deformation or position deviation of the coil at the time of molding the coil.

  • Patent number: 8208578
    Abstract: Systems, methods, and computer readable media for fractional pre-emphasis of multi-mode interconnect are disclosed. According to one aspect, the subject matter described herein includes a method for fractional pre-emphasis of multi-mode interconnect. Multiple bits of binary data are periodically received. For each period, the multiple bits of binary data are encoded into multiple scalar values, each value representing a level of an analog signal to be output over a multi-mode interconnect system during the current period. Multiple analog signal outputs are generated corresponding to multiple scalar values, each signal output being driven to a level according to its corresponding scalar value. For each representative scalar value, a difference between the scalar value generated during the current period and the scalar value generated during the previous period is determined, and a pre-emphasis signal that is proportional to the difference is generated.

  • Publication number: 20070138708
    Abstract: The present invention relates to a filter used in a gas generating apparatus of a car airbag. The car airbag is equipped with a gas generating apparatus for generating high temperature and high pressure, in which gunpowder is exploded by ignition of an igniter, by which a gas generating agent is burned. By combustion of a gas generating agent, a high temperature and high pressure gas is generated, which should be cooled down to be suitable for expansion of an airbag while impurities contained in the gas are removed. The present invention relates to a filter prepared by sintering a perforate plate with metal powder prepared by processing machining chips to meet the foregoing requirements.
