摘要:
An air filtration cartridge has annular filter media having a hollow interior and extending axially between first and second distally opposite end caps. The first end cap is an outlet end cap having flow straightening structure integrally formed therewith and spanning the hollow interior. The second end cap is a closed end cap having an interior face having quarter wave resonators formed by blind holes therein.
摘要:
Gas treatment systems are described that allow for modular development of gas treatment systems, for example exhaust gas aftertreatment systems, using generally standardized parts. A number of subsections are provided, including a treatment subsection containing an exhaust gas treatment device for treating exhaust gas. The treatment subsection is designed to be connectable to an inlet subsection, an outlet subsection, or other subsections in a manner that allows the positions, both longitudinally and rotationally, of the treatment subsection relative to adjacent subsections to be adjusted as required during assembly. This permits an infinite number of length and/or clocking configurations for the aftertreatment system to be manufactured.

An engine intake resonator and manufacturing method is provided by a pair of molded sheets mated to each other along a plane and defining a plurality of tubular channels therebetween and having different length for attenuation of different frequencies.
摘要:
A system and method for interfacing peripheral devices to a computer universal serial bus is disclosed. The system is adaptable to a wide variety of peripheral devices and features a user-configurable serial EEPROM coupled to the interface in which vendor specific data can be stored for use by the interface. Interface parameters may also be selected by an externally controllable configuration switch.

Currency note sorting devices and systems, and corresponding methods of identifying and sorting currency notes are described herein. A method for sorting currency notes that includes receiving currency notes, identifying the denomination of the currency notes, and distributing the currency notes to slots of a wallet based on the identified denomination. The wallet slots include staggered braille tabs to aid visual-impaired users of the wallet.
摘要:
An exhaust aftertreatment system, including injection of chemical species, has a mixer in the exhaust pipe between the injector and the aftertreatment element. The mixer is provided by a stamped muffler flange.
摘要:
An acoustic silencer is provided by a tubular member extending along an axis and having a hollow interior defining an axial flow path therethrough. The tubular member has a sidewall with an interior face facing the hollow interior and having quarter wave resonators formed by blind holes therein.
摘要:
An exhaust aftertreatment filter is provided with localized and efficient heating for regeneration. Electrical and/or thermal conductors are wound with filter media sheets into a filter roll and/or conductors are provided at axial ends of the filter roll and/or microwave radiation is used for localized hot zone heating. Regeneration is provided at lateral slices of the filter roll lying in a plane extending transversely and radially relative to the filter roll axis.
摘要:
An active silencer for a vehicle exhaust system that has a low profile so that it can be hung underneath the vehicle in a conventional manner without altering the vehicle. The silencer has a chamber isolated from the exhaust flow in which one or more speakers are mounted side-by-side. The speakers face downwards and share a common tuning chamber within the isolated chamber. The tuning chamber is ported to a mixing chamber where the canceling acoustic waves mix with noise from the exhaust flow before the exhaust noise exits to the atmosphere.
