    • A method and apparatus for real-time measurement of combustion characteristics of each combustion event in each individual cylinder coupled with an ability to control the engine based upon the combustion characteristics are shown. The invention includes using selective sampling techniques and wavelet transforms to extract a critical signal feature from an ionization signal that is generated by an in-cylinder ion sensor, and then feeds that critical signal feature into an artificial neural network to determine a desired combustion characteristic of the combustion event. The desired combustion characteristic of the combustion event includes a location of peak pressure, an air/fuel ratio, or a percentage of mass-fraction burned, among others. The control system of the engine is then operable to control the engine based upon the combustion characteristic.
    • 示出了用于实时测量每个单独气缸中的每个燃烧事件的燃烧特性的方法和装置,以及基于燃烧特性来控制发动机的能力。 本发明包括使用选择性采样技术和小波变换从由缸内离子传感器产生的电离信号提取关键信号特征,然后将该关键信号特征馈送到人造神经网络中以确定期望的燃烧特性 燃烧事件。 燃烧事件的期望的燃烧特性包括峰值压力的位置,空气/燃料比或燃烧的质量分数的百分比等。 发动机的控制系统然后可操作以基于燃烧特性来控制发动机。

    • A portable hand-held blower vacuum apparatus (10) having a hinged inlet cover (24) with a handle (26) disposed at one end of the cover (24). The cover (24) is moveable between a closed position where the cover spans an air inlet opening (20) and an open position to allow insertion of a vacuum tube (50) in to the inlet opening (20). The handle (26) is used to move the cover between the open and closed positions. Air flows into the inlet opening (20) through a screen (38) in the cover (24), through arcuate slots (42) in a tubular extension (44) of the inlet opening (20) and over a circumferentially extending rib (46) formed on the cover (24). In an alternative embodiment, a dedicated blower is provided in which a solid, stationary cover (54) spans the inlet opening (20).
    • 一种便携式手持式鼓风机真空装置(10),其具有铰接的入口盖(24),其具有设置在盖(24)的一端处的手柄(26)。 所述盖(24)可在所述盖跨过空气入口(20)的关闭位置与允许将真空管(50)插入所述入口(20)的打开位置之间移动。 手柄(26)用于在打开位置和关闭位置之间移动盖子。 空气通过入口开口(20)的管状延伸部(44)中的弧形槽(42)并且在周向延伸的肋(46)上方通过盖(24)中的筛网(38)流入入口 )形成在盖(24)上。 在替代实施例中,提供了专用鼓风机,其中固体固定盖(54)跨过入口(20)。
