  • Publication number: 20080043399
    Abstract: A lightning protection method and its device with compound actively generated plasma and passively produced plasma are disclosed, in witch conventional lightning rods are reformed each with a plasma piping inside. The high density plasma generated by an active plasma generator is blown through the piping, spread out at the tips of the rods and compounded with the plasma passively produced by the corona discharge on the tips under the action of lightning cloud electric field. The compound plasma dissipates the electric charges, on the tips of the rods, inducted by lightning cloud electric field, and neutralizes the electric charges of the lightning cloud. Then the electric field strength in around space can be reduced, and the lightning cloud voltage puncture to the rods can be shielded and eliminated. As a result, the thunderstruck to the protected object within the protection scope related to the lightning rods of the device can be rejected.

  • Patent number: 7212908
    Abstract: A method of reducing nitrogen oxides (NOx) and particulate matter (PM) in compression ignition engine emissions. The method includes monitoring at least one engine sensor that generates a signal in response to at least one engine operating condition, and adjusting at least one engine control parameter in response to the signal such that in-cylinder spacial distribution of equivalence ratio and temperature is substantially maintained to an operating region. The operating region corresponds to a set of equivalence ratio with respect to temperature values that are substantially outside regions supportive of NOx and PM formation. The temperature values are greater than 1650 K, and the equivalence ratio values are greater than 0.5.

  • Publication number: 20070018065
    Abstract: A support structure extends upwards from a substrate and supports a tiltable platform, the upper surface of which can be a mirror, by means of spaced flexible couplings that enable the platform to tilt relative to the support structure. Respective electrodes associated with the substrate and platform control the platform tilt in response to applied signals. The platform electrodes are preferably spaced below and tilt with the platform, with the platform extending laterally from the support structure further than the platform electrodes. The platform is preferably bulk micromachined, and the support structure surface micromachined.

  • Patent number: 6390069
    Abstract: A fuel injector assembly is provided which includes a control valve actuated by a piezoelectric actuator acting through a hydraulic amplifier to facilitate pressurization of fluid fuel within the fuel injector assembly for dispersing the fuel into a combustion chamber. The piezoelectric actuator is excited by a variable voltage source to control the degree of displacement of the hydraulic amplifier to control the degree of fluid fuel dispersement by controlling the degree of displacement of the control valve. The configuration of the control valve may be such as to provide multi-step fluid fuel dispersing thereby providing a low fuel injection pressure and rate followed by a higher fuel injection pressure and rate. Multi-step fluid fuel dispersing may also be accomplished by varying the level of excitation voltage to the piezoelectric actuator.
