    • A digital slot car racing system is described which allows multiple slot cars (3 - 1 to 3 - 6) to be raced on each slot (11) of a slot car racing system. The system includes a main controller (7) which is arranged to transmit digital messages to each of the slot cars by modulating the signal applied to the slots. The slot cars are operable to use the signal applied to the slot to derive power for powering the slot car and to recover the data transmitted from the main unit. The slot cars extract the relevant data and control the speed of the slot car. The slot car racing system also includes a number of change lane track segments (351) which allow slot cars to change slots. In operation, the main unit transmits a change lane request to a slot car which, in response, transmits a signal to the change lane track segment indicating that it wants to change slot. A change lane controller then opens a gate on the change lane track segment to cause the approaching slot car to be directed onto the other slot.
    • 描述了一种数字插槽赛车系统,其允许在槽赛车系统的每个槽(11)上进行多个槽车(3-1至3-6)。 该系统包括主控制器(7),其被配置为通过调制施加到时隙的信号来将数字消息发送到每个槽车。 槽车可操作以使用施加到槽的信号来获得用于为槽车供电的功率并恢复从主单元发送的数据。 槽车提取相关数据并控制槽车的速度。 小车赛车系统还包括许多改变车道轨道段(351),其允许小汽车改变时隙。 在操作中,主单元向插槽车发送改变车道请求,该车厢作为响应,向改变车道轨道段发送指示其想要改变时隙的信号。 改变车道控制器然后在改变车道轨道段上打开门,以使接近的槽车被引导到另一个槽上。

    • Circuit board assemblies (6) consisting of printed circuit boards (7) to which surface mounted components (8) have been mounted are visually inspected by comparison with a reference circuit board assembly. A reference image (81) is visually compared with a test image (80) using the display (64) of a personal computer (63). Image data is acquired in each case by use of an optical scanner (2) in the form of a flatbed scanner. The circuit board assemblies are positioned during scanning so as to locate a major surface of the circuit board and the surface mounted components within an imaging region (44) of the scanner. Alignment of images is automatically effected by the computer so as to display images using a common frame of reference defined relative to fiducial features of the circuit board assemblies. During scanning, the boards may be supported in an upwardly facing or inverted position within a light excluding enclosure. The method has application to small and medium scale production facilities of printed circuit board assemblies.
    • 通过与参考电路板组件进行比较,目视检查由安装有表面安装部件(8)的印刷电路板(7)组成的电路板组件(6)。 使用个人计算机(63)的显示器(64)将参考图像(81)与测试图像(80)进行目视比较。 通过使用平板扫描器形式的光学扫描器(2)在每种情况下获取图像数据。 电路板组件在扫描期间定位,以将电路板的主表面和表面安装的部件定位在扫描仪的成像区域(44)内。 图像的对准由计算机自动实现,以便使用相对于电路板组件的基准特征定义的公共参考框来显示图像。 在扫描期间,板可以被支撑在不包括外壳的光的向上或向后的位置。 该方法适用于印刷电路板组件的中小规模生产设备。
