    摘要： An internal combustion engine comprises an intake system to deliver a compressed intake charge thereto. A venturi assembly is disposed in the intake system and defines a venturi defining a low pressure zone “Z” for the intake charge passing therethrough. An annular exhaust gas recirculation conduit distribution passage extends circumferentially about an inlet annulus of an intake manifold and receives diverted exhaust gas from an exhaust system for delivery to the intake charge through exhaust gas recirculation diffuser passages disposed at circumferentially spaced locations about the annular exhaust gas recirculation conduit distribution passage.

    摘要： A control system for an engine includes a restriction determination module and a valve control module. The restriction determination module determines a desired exhaust back pressure of the engine based on an exhaust flow rate of the engine. The valve control module selectively adjusts a valve position of an exhaust valve that restricts an exhaust flow of the engine based on the desired exhaust back pressure. The exhaust valve may include a valve body, a throttle plate, and an annular protrusion coupled to an inner surface of the valve body and protruding towards the throttle plate. The annular protrusion may abut a side of the throttle plate and may restrict fluid flow through an annular space between the throttle plate and the inner surface when the throttle plate is positioned in a rotational position transverse to a direction of fluid flow. A related method is also provided.

    摘要： Novel systems and methods for remotely detecting at least one constituent of a gas via infrared detection are provided. A system includes at least one extended source of broadband infrared radiation and a spectrally sensitive receiver positioned remotely from the source. The source and the receiver are oriented such that a surface of the source is in the field of view of the receiver. The source includes a heating component thermally coupled to the surface, and the heating component is configured to heat the surface to a temperature above ambient temperature. The receiver is operable to collect spectral infrared absorption data representative of a gas present between the source and the receiver. The invention advantageously overcomes significant difficulties associated with active infrared detection techniques known in the art, and provides an infrared detection technique with a much greater sensitivity than passive infrared detection techniques known in the art.

    摘要： A method of stimulating neurons in a patient's cochlea. The method uses a plurality of cochlear electrodes, substantially arranged in a linear array within the cochlea and a relatively distant electrode. Charge is injected through a first one of the cochlear electrodes and an opposite charge is injected on either the relatively distant electrode; or a set of adjacent cochlear electrodes, being adjacent to the first one of the cochlear electrodes; or on a combination of the relatively distant electrode and the set of adjacent electrodes; and choosing the electrode or electrodes on which to inject charge in dependency on sound volume to be represented.

    摘要： The speed of operation of a programmable logic device which contains internally synchronous circuit structure is increased by an improved architecture which does not require a power-up transition cycle. Synchronous operation is carried out only for one transition. In each column of the matrix of programmable cells, the rows of which are coupled to receive the logic signals upon which the device is to operate, the programmable cells of that column are coupled via a respective inverter feedback pair to a column output link of the matrix. The connection between the programmable cells of the matrix and the inverter feedback pairs are coupled to pull-down switch devices control inputs of which are coupled to the output of an OR tie, inputs or which depend upon a prescribed transition on row input links. This transition is detected by respective transition detectors which trigger only on a particular transition edge. When the row inputs to the matrix change state, the column outputs follow the transitions asynchronously, with the only delay being that imparted by the inherent delay through the inverter feedback pairs. When the row inputs switch or transition to the opposite state, the transition detector of each row provides an output which, through the OR tie, triggers the pull-down switches. These pull-down switches are capable of overriding the feedback inverter pair to force the column low if it had previously been high and if no other row is holding the column high. For this transition, the matrix operates synchronously.
