Abstract: An electronic smoking article includes an outer housing extending in a longitudinal direction, a liquid aerosol formulation, a heater operable to at least partially volatilize at least a portion of the liquid aerosol formulation and form an aerosol, a power supply operable to apply voltage across the heater, at least one light emitting diode, a charging button assembly including a conductive post operable to form a first external, electrical contact at an upstream end of the electronic smoking article, and a second external, electrical contact including a portion of an outer surface of the outer housing at the upstream end of the electronic smoking article. The first and second external, electrical contacts charge the power supply.

Abstract: A vehicle and an adjustable sound distribution system that includes an engine operable to produce a pulsation and a sound assembly coupled to the engine. The sound assembly is disposed upstream from the engine. The sound assembly is configured to generate sound from the pulsation. The sound assembly includes a housing defining a cavity configured to resonate the sound that exits the sound assembly. The sound assembly also includes a first member movable to change a frequency of the sound that exits the sound assembly.

Abstract: An air duct system includes a first member that includes a groove disposed around only a portion of an opening. A second member defines a passage extending along a longitudinal axis, and is in fluid communication with the opening of the first member. The second member includes a flange disposed within the groove of the first member. The engagement between the flange and the groove restricts relative movement between the first member and the second member in an axial direction along the longitudinal axis. An attachment system connects the first member and the second member together, and restricts relative movement between the first member and the second member in a lateral direction that is transverse to the longitudinal axis, to secure the flange within the groove.

Abstract: An air induction system for delivering equal quantities of combustion air to an internal combustion engine has an air box assembly comprising a housing that defines a filter chamber that is configured to receive an air filter assembly, an air inlet that admits the fresh air into the housing and the filter chamber and outlets extending from the housing. The air filter assembly further comprises a filter media disposed between the air inlet and the outlets to define a filtered air chamber on a flow side of the filter media and a partition extending across the filtered air chamber to divide filtered, fresh air passing through the filter media into two flow paths, the divided flows paths exiting the housing and the filtered air chamber through the outlets.

Abstract: An air induction system includes a housing defining an inner cavity. The housing has a first wall with a first air inlet, a second wall with a second air inlet, and an air outlet for directing air to the vehicle engine. A panel filter is mounted within the housing and divides the inner cavity so that the first inlet and the second inlet are upstream of the panel filter and the outlet is downstream of the panel filter when air flows through the housing from either of the air inlets to the air outlet and through the panel filter from a first side of the filter to a second side of the filter. The first air inlet, the second air inlet, and the panel filter are positioned so that the first side is lower than the second side when the housing is installed in the vehicle.

Abstract: Methods and apparatuses are provided for an air inlet duct of an internal combustion engine. The air inlet duct includes a tubular housing. An inner wall has a plurality of perforations. The inner wall is disposed within the tubular housing such that the tubular housing includes at least two flow passages. A valve set is associated with a first flow passage of the at least two flow passages. The valve set selectively controls airflow through the first flow passage such that the first flow passage functions in a least one of a pass-through mode and a tuning mode.

Abstract: An air duct assembly supplies air from an air cleaner housing to an engine throttle and includes a first duct connected to the air cleaner housing and a second duct connected to the engine air intake. Open ends of the first and second ducts are spaced from one another and the second duct has a flared bell mouth at its open end. The second duct includes a sleeve that defines an attenuation chamber. A flexible bellows overlies the first and second ducts and the sleeve, and extends across the space between the first and second ducts to provide an airtight connection therebetween and flex during relative motion between the air cleaner housing and the engine air intake. A hydrocarbon adsorbing material can be housed within the attenuation chamber.
