    • A human-portable utility locator system for locating and tracing a buried utility line characterized by an electromagnetic field emission. The locator may include a horizontal spaced sensor pair for detecting the horizontal field asymmetry of the emitted field in one or more independent frequency bands, which is employed to assist in determining an accurate “virtual depth” measurement for producing detection events. An event detector may be disposed to detect events corresponding to extremum in the B-field gradient with respect to time and a user interface (UI) coupled to the event detector signals the detected event to a user. In a preferred embodiment, one pair of spaced-apart 3D magnetic sensor arrays is disposed substantially orthogonal to another intermediate spaced-apart pair of sensors.
    • 一种人造便携式实用定位系统,用于定位和跟踪以电磁场发射为特征的埋地公用事业线。 定位器可以包括用于检测一个或多个独立频带中的发射场的水平场不对称性的水平间隔传感器对,其用于帮助确定用于产生检测事件的精确“虚拟深度”测量。 可以设置事件检测器以相对于时间检测对应于B场梯度中的极值的事件,并且耦合到事件检测器的用户界面(UI)将检测到的事件发信号给用户。 在优选实施例中,一对间隔开的3D磁传感器阵列基本上与另一中间间隔开的传感器对正交设置。

    • A floating feedhead having a variable sheetpath for an electrophotographic printing machine. A feeder for feeding sheets from the top of a stack to a processor for a printing machine is disclosed. The feedhead is of a standard retard feed type having either a nudger roll/feed roll or a feed belt in combination with a retard member to separate sheets. The feedhead is connected to the sheet delivery area of the machine by a variable length, variable speed sheetpath. The sheetpath has a drive member such as a drive nip in cooperation with the feedhead. When the sheetpath is at its longest the feedhead and variable drive member operate at a higher speed to deliver the sheets to the sheet intake area at a predetermined time interval. As sheets are fed and the sheetpath becomes shorter, the variable drive and feedhead slow to maintain proper sheet timing. The sheetpath may be of a telescopic baffle configuration or could alternatively be a variable speed vertical transport arrangement.
    • 具有用于电子照相印刷机的可变片材路径的浮动馈送头。 公开了一种用于将纸张从堆叠的顶部进给到用于印刷机的处理器的进料器。 进料头具有标准延迟进料型,其具有微型滚筒/进料辊或进料带以及用于分离薄片的延迟构件。 进料头通过可变长度,可变速度的纸张路径连接到机器的纸张输送区域。 片材路径具有与进给头协作的诸如驱动辊隙的驱动构件。 当片材路径最长时,馈送头和可变驱动构件以更高的速度操作,以预定的时间间隔将片材输送到片材进入区域。 当纸张进给并且纸张路径变短时,可变驱动器和进给头缓慢以保持适当的纸张定时。 片材路径可以是伸缩挡板构造,或者可以是变速垂直传送装置。
