    • Various methods of hot-electron imaging a workpiece are provided. In one aspect, a method of examining a workpiece is provided that includes directing a first photon at a photodetector at a first known time and stimulating a circuit device of the workpiece at a second known time to produce a condition in the circuit device conducive to photon emission. At least one photon emitted by the circuit device in response to the stimulation is detected. The first photon increases the quantum efficiency of the photodetector in detecting the at least one photon. The detection of the at least one photon relative to the first known time and the second known time is time correlated to temporally distinguish the first photon and the at least one photon and to temporally correlate the stimulation of the circuit device to the detection of the at least one photon.

    • Methods and apparatus for plugging cells of honeycomb structures are disclosed. A first method covers the honeycomb structure's end face with a mask having a body and plurality of sized openings positioned to oppose certain cell channels, wherein the outer edge of the body extends radially outwardly from the end face. A film also extends outwardly of the end face, and a plug of material is provided upon the film. The mask and film material are sealed to one another, and a force is applied to the film forcing the material through the mask and into the cells. Also disclosed is adhering a mask to a first end face of the honeycomb structure such that the mask has an outer portion that extends radially beyond an outer edge of the honeycomb; providing a volume of plugging material; clamping the outer portion between a first clamping portion and a second clamping portion; and transferring the plugging material into the honeycomb. Also disclosed are methods and apparatus for cutting the plugging material between the mask and a pre-plugging chamber to form a substantially planar surface thereon.
    • 公开了蜂窝结构体封闭孔的方法和装置。 第一种方法覆盖蜂窝结构的端面,其具有带有本体的掩模和多个尺寸的开口,定位成与某些单元通道相对,其中本体的外边缘从端面径向向外延伸。 薄膜还从端面向外延伸,并且在薄膜上提供材料塞。 掩模和膜材料彼此密封,并且将力施加到膜上,迫使材料通过掩模并进入孔中。 还公开了将掩模粘附到蜂窝结构体的第一端面,使得掩模具有径向延伸超过蜂窝的外边缘的外部部分; 提供一定量的堵塞材料; 在第一夹持部分和第二夹紧部分之间夹紧外部部分; 并将封堵材料转移到蜂窝中。 还公开了用于在掩模和预堵塞室之间切割堵塞材料以在其上形成基本平坦的表面的方法和装置。

    • A seat assembly for a motor vehicle includes a seat frame having a front member, a rear member, and side members extending between the front and rear members. The seat assembly also includes a trim cover material extending in tension over the seat frame and including a perimeter edge disposed about the front, rear, and side members thereof. The trim cover material includes a pocket formed along its perimeter edge. A tensioning mechanism includes a cable having a middle portion and cable ends extending out of the pocket. The tensioning mechanism further includes a tension block having opposing adjustment arms each coupled to one of the cable ends. Movement of the opposing adjustment arms towards and away from each other selectively adjusts the tension in the trim cover material disposed about the seat frame.
