An exhaust aftertreatment system comprises an injector for injecting urea water into an exhaust duct, and a denitration catalyst disposed downstream of the injector with respect to a flow of exhaust gas. The exhaust aftertreatment system reduces nitrogen oxides in the exhaust gas by the denitration catalyst while using ammonia produced from the urea water injected from the injector. The urea water is injected along a direction of the flow of the exhaust gas within the exhaust duct, and a porous plate is disposed in multiple stages in a space of the exhaust duct such that droplets of the injected urea water impinge against the porous plate before reaching a wall surface of the exhaust duct. A surface of the porous plate subjected to the impingement of the droplets is arranged to face downstream with respect to the flow of the exhaust gas. Deposition of the urea water is prevented by causing film boiling when the droplets impinge against the porous plate, and the urea water reflected by the porous plate is uniformly dispersed into the exhaust gas. Thus, the urea water is uniformly dispersed into the exhaust gas without increasing a pressure loss of the exhaust gas. The urea water is prevented from depositing on the wall surface and producing a precipitate in the form of a solid.

A photonic structure for “white” light generation by phosphors under the excitation of a LED. The photonic structure mounts the LED and an optically transparent nanocomposite matrix having dispersed therein phosphors which will emit light under the excitation of the radiation of the LED. The phosphors dispersed in the matrix may be nanocrystalline, or larger sized with the addition of non light emitting, non light scattering nanoparticles dispersed within the matrix material so as to match the index of refraction of the matrix material to that of the phosphors. The nanocomposite matrix material may be readily formed by molding and formed into a variety of shapes including lenses for focusing the emitted light. A large number of the photonic structures may be arranged on a substrate to provide even illumination or other purposes.

A portable remote wireless control for establishing different temperatures in separate portions of a building. The remote control not only regulates hot and cold airflow through rotatable damper vanes in one or more diffusers, but it also recharges the batteries that power the wireless receiver, servomotor and servomotor controls that selectively rotate the damper vanes. Damper vane rotation regulates air flow from the diffuser to control the temperature in the portion of the building. The damper vanes, moreover, are of a light plastic with a marginal band of a foam material to enable the vanes to rotate silently and freely also to form a seal that eliminates a great deal of air seepage past the individual vanes.

An ion source capable of generating and/or emitting an ion beam which may be used to deposit a layer on a substrate or to perform other functions is provided. The ion source includes at least one anode and at least one cathode.

Walls of the recess optionally may be insulated using, for example, ceramic. One or more holes may be provided to allow a supply of gas to flow into the recess, and those holes optionally may be tapered such that they narrow towards the recess. Thus, certain example embodiments produce an ion source having a higher energy efficiency (e.g., having increasing ion energy).

In response to simultaneous ON settings of a heater switch signal HSW and an eco switch signal ESW, an eco priority map is set to an intermittent operation permission map (step S350). The heater switch signal HSW is output from a heater switch that is operated to warm up a passenger compartment, while the eco switch signal ESW is output from an eco switch that is operated to give preference to improvement in fuel consumption of the vehicle over the heater function. The eco priority map is designed to allow intermittent operation of an engine in a lower range of cooling water temperature Tw of the engine than that in a heater-on state map set in response to OFF setting of the eco switch signal ESW and ON setting of the heater switch signal HSW. The control procedure of the invention refers to the intermittent operation permission map and determines whether the intermittent operation of the engine is allowed or prohibited, based on the current cooling water temperature Tw and a starting-time cooling water temperature Tst, which represents a temperature of cooling water at a first start of the engine since activation of the vehicle system (step S360).

An embedded system may distribute, e.g. at the point of coupling to a main power grid, information corresponding to one or more operational parameters (e.g. phase angle, frequency, amplitude, etc.) of a power delivery device to other power delivery devices, using a deterministic communication link. Updates of some or all of the information may be transmitted at future or past points in time, for example at defined time intervals. Time synchronization methods, e.g. a locked instantaneous interpolation mechanism may be used to create a coordinated time, shared among all power delivery devices. Various operating parameter mismatches, e.g. a phase mismatch between power delivery devices delivering power to the power grid, may thereby be reduced to less than a specified, negligible value. This creates tight time synchronization between the power delivery devices and allows them to interoperate in a manner that stabilizes rather than destabilizes the power grid.
