    • A fuel fired appliance exhaust gas parameter sensor for continually detecting gas parameter emissions, such as CO, NOx and O2, may be located above the appliance near the appliance exhaust outlet. The sensor may be located near or under a draft hood located near the exhaust outlet. The sensor remains relatively cool by draft air moving from outside the draft hood and into a chimney, the draft being hastened by the heated, rising chimney gases. A sensor bracket may be attached to the appliance and the sensor to appropriately position the sensor under the draft hood. Alternatively, the sensor may be located on a tube that continually samples combustion exhaust. The tube may be located outside of the draft hood perimeter to maintain a low sensor temperature, while multiple tube coils around the exhaust outlet may be used to further cool the sampled gas.
    • 用于连续检测气体参数排放的燃料燃烧器具废气参数传感器,例如CO,NO x和O 2,可以位于器具排气口附近的器具上方。 传感器可以位于排气口附近的引风机附近或下方。 通过从引风机外部移动并进入烟囱的通风空气,传感器保持相对冷却,通气被加热的上升的烟囱气体加速。 传感器支架可以连接到器具和传感器,以将传感器适当地定位在通风罩下。 或者,传感器可以位于连续地对燃烧排气进行采样的管上。 管可以位于引风机周边的外侧以保持低的传感器温度,而可以使用排气出口附近的多个管线圈来进一步冷却采样的气体。

    • Disclosed is an interactive educational apparatus, ideally suitable for children. A set of symbol pieces, preferably in the form of letter blocks are provided. An interface board is provided for accommodating one or more selected symbol pieces and a sensor on said interface board generates a signal identifying each symbol piece when placed on said interface board. Media files are stored on a storage medium and each media file has an associated tag. A processor is programmed to match a search key represented by one or more selected symbol pieces with said tags. A display device displays one or more media files having identifier tags matching said search key represented by said selected symbol pieces. These identifier tags provide a means to match up the media files with each search key generated by placement of the symbol pieces on the interface board.
    • 公开了一种交互式教育设备,理想地适用于儿童。 提供了一组符号块,最好是以字母块的形式。 提供用于容纳一个或多个所选符号片的接口板,并且当放置在所述接口板上时,所述接口板上的传感器产生识别每个符号片的信号。 媒体文件被存储在存储介质上,并且每个媒体文件具有关联的标签。 处理器被编程为将由一个或多个所选符号片段表示的搜索关键字与所述标签相匹配。 显示装置显示具有与由所选择的符号片段表示的所述搜索关键字相匹配的标识符标签的一个或多个媒体文件。 这些标识符标签提供了将媒体文件与通过将符号片放置在接口板上而生成的每个搜索关键字的方法。
