Abstract: Colloidal isopressing provides a rapid method to form an engineering shape from a powder slurry, previously filtered to remove strength degrading inclusions. A slurry composed of a weakly attractive particle network, produced with a short-range, repulsive interparticle par potential, is consolidated to make a body with a high particle density that is easily fluidized by vibration. The fluid-like body is injected into a flexible mold and subjected to a larger isostatic pressure to force particles into contact. This creates a strong, elastic body with the shape of the mold. Because the particles are forced into contact at a high pressure, the liquid remaining within the component can be removed by evaporation without shrinkage, avoiding fracture during rapid drying.

Abstract: The present invention provides for a system and process for enhancing internal combustion engine aftertreatment applications by superheated fuel injection. The system includes a fuel supply upstream of a fuel injector of an aftertreatment application. The system also includes a heater for heating the fuel in the fuel supply. A temperature controller can be used to maintain the heated fuel in a liquid form. When liquid fuel in the pressurized fuel supply is heated, then upon exiting the injector the pressure of the fuel drops rapidly, resulting in atomization of the liquid. The vaporized fuel thereby produced is comprised of extremely small droplets and is elevated in temperature, which reduces the possibility of condensation on internal surfaces of the aftertreatment system. This fine droplet size and resistance to condensation enhances the NOx conversion efficiency of adsorbers. Problems related to premature aging of catalysts and fuel penalties can also be reduced.

Abstract: Dummy features (64, 65a, 65b, 48a, 48b) are formed within an interlevel dielectric layer (36). A non-gap filling dielectric layer (72) is formed over the dummy features (64, 65a, 65b, 48a, 48b) to form voids (74) between dummy features (64, 65a, 65b, 48a, 48b) or between a dummy feature (48a) and a current carrying region (44). The dummy features (64, 65a, 65b, 48a, 48b) can be conductive (48a, 48b) and therefore, formed when forming the current carrying region (44). In another embodiment, the dummy features (64, 65a, 65b, 48a, 48b) are insulating (64, 65a, 65b) and are formed after forming the current carrying region (44). In yet another embodiment, both conductive and insulating dummy features (64, 65a, 65b, 48a, 48b) are formed. In a preferred embodiment, the voids (74) are air gaps, which are a low dielectric constant material.

Abstract: Dummy features (64, 65, 48a, 48b) are formed within an interlevel dielectric layer (36). Passivation layers (32 and 54) are formed by electroless deposition to protect the underlying conductive regions (44, 48a, 48b and 30) from being penetrated from the air gaps (74). In addition, the passivation layers (32 and 54) overhang the underlying conductive regions (44, 48a, 48b and 30), thereby defining dummy features (65a, 65b and 67) adjacent the conductive regions (48a, 44 and 48b). The passivation layers (32 and 54) can be formed without additional patterning steps and help minimize misaligned vias from puncturing air gaps.

The support frame cooperates with the headliner body to provide a sufficient structural characteristic such that the headliner assembly is self-supporting.

Abstract: Exhaust flow from an internal combustion engine is divided in a predetermined ratio between two adsorber catalysts arranged in parallel during lean operation. A regeneration cycle time is predetermined and regeneration is accomplished by injecting hydrocarbons into a catalyst leg having a reduced exhaust flow. Upon regeneration of the catalyst, the exhaust gas flow distribution is reversed and the opposite catalyst is regenerated while the regenerated catalyst bears the brunt of the exhaust flow. The exhaust flow then reverts to a normal (e.g. 50—50) flow distribution until another regeneration cycle is warranted. A catalytic soot filter placed upstream of each adsorber is also regenerated by hydrocarbon injection. The addition of the catalytic soot filter provides more time and surface area for the hydrocarbon to react with the oxygen. Some of the diesel fuel is reformulated into hydrogen and carbon monoxide for superior regeneration.

Abstract: The present invention is directed to a polymerizable composition including a polymerizable monomer component and a nanoparticle material, having a refractive index of from 1.595 to 1.695. When at least partially cured, the polymerizable composition is especially useful for ophthalmic applications.

Abstract: The present invention provides for adsorber catalysts arranged in parallel. The exhaust flow from the engine is divided in a predetermined ratio between the two catalysts during lean operation (e.g. 50-50). At a predetermined regeneration time (for example, when the adsorber catalyst is 20% full), the exhaust gas flow is reduced through the parallel leg that is to be regenerated (e.g. 20-80). A quantity of hydrocarbon is injected into the reduced-flow leg in order to make the mixture rich. Once the leg has been regenerated, the flow distribution between the parallel legs is reversed, and the other catalyst leg is regenerated while the other side (which is now clean) receives the majority of the exhaust flow. Once both catalyst legs have been regenerated, the exhaust flow is adjusted back to normal (e.g. 50-50) until the catalysts are again ready for regeneration and reduction. A catalytic soot filter is positioned downstream from the adsorber.

Abstract: A method for fabricating a region of low dielectric constant between metal layers of a substrate, such as an integrated circuit, that eliminate or minimize the problems associated with the existing and future low-k materials and processes. The method utilizes a sacrificial layer or an ultra low-k layer to form a major, but not entire, portion of the dielectric layer between the metal layers, using innovative integration schemes and CMP processes.

Abstract: A conductive line varies in thickness to assist in overcoming RC delays and noise coupling. By varying line thickness, variation in conductor width is avoided if necessary to maintain a specified minimum pitch between conductors while maintaining predetermined desired RC parameters and noise characteristics of the conductive line. Conductor depth variation is achieved by etching a dielectric layer to different thicknesses. A subsequent conductive fill over the dielectric layer and in the differing thicknesses results in a conductive line that varies in thickness. Different conductive line thicknesses available at a particular metal level can additionally be used for semiconductor structures other than a signal or a power supply conductive line, such as a contact, a via or an electrode of a device. The thickness analysis required to determine how interconnect thickness is varied in order to meet a desired design criteria may be automated and provided as a CAD tool.

Abstract: A process for fabricating micro-acousto-optic modulators using microelectronics fabrication technology. First, a set of trenches is etched into a substrate. Then, a transducer material is deposited into these trenches, followed by removal of any transducer material located above the surface of the substrate. Next, a second set of trenches is etched on both sides of the transducer material, between the transducer material and the substrate. Then, an electrode material is deposited into the second set of trenches. Finally, any electrode material located above the surface of the substrate is removed such that the surface of the substrate is co-planar with the electrode and transducer materials.

Abstract: A system and method are disclosed for routing telephone calls directed to a wireless unit located in the wireless network to a landline device located in the landline network. The system utilizes a location register in the form of a service control point (SCP) located in the landline network to store certain information pertaining to landline numbers and respective routing numbers associated with landline devices. The SCP is functionally coupled to a Visitors' Location Register (VLR) as well as to a landline network element that facilitates the routing of communications to both landline devices and over to the MTSO and its associated Home Location Register (HLR) in the wireless network.
