Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a row level security. One of the methods includes receiving, by a computer device executing at least part of a functional logic tier of an application, a request from a user for one or more objects present in the functional logic tier. The method includes determining that a type of the requested objects is associated with an object representative of instance level security. The method includes in response to determining that the type is associated with the object, determining access is authorized to at least some of the objects, determining access comprising accessing, by a computer device executing at least part of a data tier of the application, a link data structure that links the user with at least some of the objects. The method also includes providing the at least some of the objects to the user.

An air pipe for an intake tract of an internal combustion engine may include at least one air channel for guiding a through-flow of air to at least one compressor arranged downstream thereof. An air guiding device may be arranged to influence a forward flow of air running in a direction towards the at least one compressor and facilitate reducing turbulences of the air flow.

A vehicle air filter housing having a broad band tuner. The housing is formed from a tray having a divider wall defining an unfiltered air induction chamber and a tuner chamber. A cover securable to the tray includes a second divider wall defining a filtered air chamber and a flow path chamber. A filter member provides a seal between the tray and the cover, and holds an air filter between the unfiltered air chamber and the filtered air chamber. A plate securable to the flow path chamber has a plurality of perforations. Air inducted through the inlet passes through the air filter and flows through the flow path chamber at a velocity whereby the filtered air passes over the perforated plate and predetermined frequencies pass through the plate perforations for attenuation in the tuner chamber. The tuners in the tuner chamber may be sized to attenuate different frequencies.

An inlet duct for an internal combustion engine includes a duct member made of a compression molded fiber material. The duct member includes a main body and end portions provided on opposite sides in an axial direction of the main body. The main body includes at least one high-compression portion and at least one low-compression portion, which is made through compression molding at a compression ratio lower than that of the at least one high-compression portion. The at least one low-compression portion extends throughout a length in the axial direction of the main body.

A bearing plate damper for a supercharger comprising a bearing plate, a first shaft bore and a second shaft bore in the bearing plate, a recess centered between the first shaft bore and the second shaft bore, and a perforated panel in the recess.

An acoustic component is provided with a flow channel for a fluid. The flow channel has an inlet pipe and an outlet pipe. A flow channel section is arranged between the inlet pipe and the outlet pipe, wherein the flow channel section has a silencer volume connected in the flow channel section via openings to the flow channel. A flow deflection device is arranged at least in the flow channel section with the silencer volume, wherein the flow deflection device deflects a flow of the fluid in the flow channel section with the silencer volume away from the openings. The openings in the flow channel section are arranged in a sheltered zone of the flow deflection device.

A throttle body fuel injection system including a throttle body with at least one air intake, a fuel injector coupled to the throttle body at a fuel port and an annular ring coupled to the cylindrical inner wall of the air intake. The annular ring includes a primary fuel discharge orifice adjacent to the fuel port and a plurality of secondary fuel discharge orifices arranged radially around the annular ring for spraying atomized fuel into the air intake.

The present invention relates to a vehicle silencer comprising: a first case provided in a vehicle; a second case coupled to the first case; a resonant chamber positioned between the first case and the second case; and a passing hole formed by penetrating the second case, such that the inside of the second case and the resonant chamber communicate with each other therethrough, wherein the second case includes a first passing member formed such that the thickness thereof gradually decreases toward a first direction.

A throttle body fuel injection system including a throttle body with at least one air intake, a fuel injector coupled to the throttle body at a fuel port and an annular ring coupled to the cylindrical inner wall of the air intake. The annular ring includes a primary fuel discharge orifice adjacent to the fuel port and a plurality of secondary fuel discharge orifices arranged radially around the annular ring for spraying atomized fuel into the air intake.

A supercharger assembly comprises a housing, a rotor bore with an outer wall, an outlet in an outlet plane, an inlet in an inlet plane perpendicular to the outlet plane, and an outlet divider wall. The supercharger assembly comprises a first recess, a first perforated material covering the first recess, and an outlet resonator. The first recess is separated from the outlet by the outlet divider wall. The first recess is located between the outer wall and the first perforated material.
