摘要:
A system is adapted to manage the distribution of content to one or more cooperating media/substrates. The system receives data representative of environment conditions for one or more cooperating media/substrates adapted to display digital content. The media/substrates may be located in public spaces. The system compares the received data representative of environment conditions with selection criteria to identify content for distribution to the media/substrates. The selected content is distributed to the one or more cooperating media/substrates.

An exhaust valve for an exhaust component includes a shaft defining an axis and a flapper valve that is fixed to the shaft for rotational movement about the axis. The flapper valve is mounted within an interior cavity of a valve housing that is defined by an inner diameter. The flapper valve comprises a disc-shaped body that has a maximum flapper diameter that is less than the inner diameter. A unidirectional drive unit is used to move the flapper valve between open and closed positions such that the flapper valve only rotates in one direction about the axis.

A muffler assembly includes first and second muffler components that are each formed as a single piece. The first muffler component includes a first outlet pipe portion, a first bypass pipe mount portion, and a first resonator shell portion. The second muffler component includes a second output pipe portion, a second bypass pipe mount portion, and a second resonator shell portion. The first and second muffler components are positioned in an overlapping relationship such that respective portions are aligned with each other to form an outlet pipe, a bypass pipe mount, and a resonator shell. A noise attenuation valve assembly is also installed within the first and second muffler components. The bypass pipe mount is positioned at a non-perpendicular orientation relative to the outlet pipe such that a bypass pipe having a straight end mount can be received within the bypass pipe mount to bypass the noise attenuation valve assembly.

A display page assembly for holding substantially planar articles includes a base layer, an anchoring layer, and a protective layer. The anchoring layer is attached to the base layer and includes a plurality of mounting apertures formed therein. The plurality of mounting apertures are arranged for receiving a portion of a substantially planar article therein to secure the substantially planar articles relative to the page. The protective layer is attached relative to the anchoring layer to cover the substantially planar article.

An exhaust component includes at least one muffler that has an inlet and an outlet. One pipe body is connected to each of the inlet and the outlet. The pipe bodies each have first and second ends that define a respective overall pipe length. Each pipe body defines a sole exhaust flow path between their first and second ends. A passive valve assembly is mounted outside of the muffler and within one of the pipe bodies. The passive valve assembly is positioned at a location within a first 25% of the overall pipe length of one of the pipe bodies relative to the inlet or outlet of the muffler.

An exhaust valve assembly includes a valve body, a valve supported by a shaft within the valve body, and an actuator that moves the valve relative to the valve body to control exhaust flow. The actuator is thermally isolated from the valve by a linkage mechanism that cooperates with exhaust flow to move the valve between open and closed positions. The actuator temporarily contacts the linkage mechanism to initiate opening and closing movement but then moves out of contact with the linkage mechanism as the exhaust flow exerts a force against the valve to move the valve to a fully open or fully closed position. This temporary contact between the linkage mechanism and the actuator reduces heat transfer from the valve to the actuator.

A control mechanism for a noise attenuation valve in a vehicle exhaust system is configured to significantly reduce operational noises. The noise attenuation valve includes a flapper valve (18) that is supported on a shaft (16) for rotation within an inlet tube (14). The shaft is coupled to an actuator (27) with a linkage assembly (30). The linkage assembly (30) includes a lever (42) that contacts noise attenuation pads (48) at maximum travel limits defined by a backing plate (46) to reduce operational noise. In one example configuration, the actuator provides a bottomless solenoid configuration and utilizes a pulse width modulation control module to further reduce operational noises.

An exhaust valve assembly includes a flapper valve that is mounted on a shaft for rotation within an exhaust component housing between a closed position, an intermediate position, and an open position. An electric actuator is coupled to the shaft to control movement of the flapper valve. The electric actuator moves the flapper valve to the open position for high speed engine conditions. When engine speeds are lowered, and while all engine cylinders remain active, the electric actuator moves the flapper valve to the intermediate position. Once the flapper valve is in the intermediate position, if an engine cylinder is subsequently deactivated, the electric actuator quickly and quietly moves the flapper valve from the intermediate position to the closed position.
摘要:
An exhaust system includes an exhaust tube for conveying a heated exhaust flow from an engine. A valve is mounted at least partially within the exhaust tube for noise attenuation. The valve includes a bias member mounted outside of the engine exhaust tube within a heat transfer environment to maintain the bias member at a low temperature. The bias member biases the valve against the heat exhaust flow toward a predetermined position. The valve is mounted within a section of the tube having a smaller cross-sectional area and pivots into a larger cross-sectional area section of the exhaust tube to avoid interference with tube walls and provide a relatively large range of movement.
