摘要:
A passenger vehicle comprises a passenger compartment with an interior space. An HVAC system conditions fresh air from outside the vehicle, wherein the HVAC system includes a main blower for delivering conditioned air to the interior space. An air extractor valve is fluidically coupled between the interior space and the outside, wherein the air extractor valve opens in response to a higher pressure in the interior space than an outside pressure. The air extractor valve substantially blocks air flow from the outside to the interior space. A supplemental blower is integrated with the air extractor valve for directing an exhaust flow from the interior to the outside, wherein the supplemental blower is activated as a function of the main blower. Alternatively, the supplemental blower is activated in response to a door being opened, enhancing the ability of the extractor to reduce door closing effort.

A railroad friction-modification system for applying a friction modifier to a section of railroad track, the system comprising an external storage tank for storing the friction modifier, a railroad friction-modification assembly for applying the friction modifier, a tube for connecting the external storage tank to the railroad friction-modification assembly, and a mounting assembly for securing the railroad friction-modification assembly to the rail. The railroad friction-modification assembly includes an expandable membrane for storing the friction modifier, an inlet valve for receiving the friction modifier from the external storage tank, a housing for securely containing the expandable membrane, at least one outlet valve for expelling the friction modifier from the expandable membrane upon the application of a force, and a nozzle for directing the expelled friction modifier onto the section of railroad track. The force is applied by the wheel of a railroad car, such that the railroad friction-modification assembly pumps the friction modifier in a peristaltic action.

Provided herein are devices and methods for the micro-isolation of biological cellular material. A micro-isolation apparatus described can comprise a photomask that protects regions of interest against DNA-destroying illumination. The micro-isolation apparatus can further comprise photosensitive material defining access wells following illumination and subsequent developing of the photosensitive material. The micro-isolation apparatus can further comprise a chambered microfluidic device comprising channels providing access to wells defined in photosensitive material. The micro-isolation apparatus can comprise a chambered microfluidic device without access wells defined in photosensitive material where valves control the flow of gases or liquids through the channels of the microfluidic device. Also included are methods for selectively isolating cellular material using the apparatuses described herein, as are methods for biochemical analysis of individual regions of interest of cellular material using the devices described herein. Further included are methods of making masking arrays useful for the methods described herein.

An apparatus and method of forming a stringer or an integral stringer and fuselage skin. The apparatus may be a solid bladder made of silicone, urethane, or any similar material or combination thereof. The method may comprise placing composite material onto a surface of a tooling having a channel sized and shaped to correspond to a desired stringer size and shape. Then the solid bladder may be placed onto the composite material relative the channel. The shape of the solid bladder may correspond to the shape of the channel. Composite material may then be placed over the solid bladder, vacuum-sealed against the bladder and the tooling, and cured to harden the composite material, thereby forming a stringer or an integral stringer and fuselage skin.

An attachment between a heat exchanger and a cell panel of a furnace includes a cell panel including a plurality of cell panel openings and a heat exchanger having a plurality of cells. Each cell has a cell outlet insertable into a cell panel opening of the plurality of cell panel openings. A compressible gasket is insertable between the cell panel openings and the cell outlets and securable therein when the heat exchanger is secured to the cell panel. A crimping tool for securing a heat exchanger cell outlet to a cell panel of a furnace includes a male portion including a split die having two die halves and a die expander configured to separate the two die halves to engage an inner surface of the cell outlet. A female portion applies a force to the cell outlet to crimp the cell outlet to the cell panel.

A method, system, computer system and computer program product to interact with a user of a computer system or service via more than one communication channel, such as a telephone channel and a web channel. A determination can be made based upon information gathered via the multiple communication channels that communication between a server and one communication channel is related to communication between the server and another communication channel. Related information gathered via the multiple communication channels can be identified to form a more complete picture of information about the user's problem with a problem entity. A potential action to help the user find a solution can be determined from information gathered from all communication channels. An automated option can be provided via one of the communication channels, and an automated suggestion to select the option can be made via a coordinated communication channel.
