    • An alignment system includes a first module having a plurality of emitters and a first receiver configuration located on the face of the first module. A second module has a second plurality of emitters and a second receiver configuration located on the face of the second module. First and second trigger signal generators fire the first and second plurality of the emitters. The generated signals are sensed by at least some of the receivers. A converter arrangement obtain and convert the received signals into digital data representative of the readings received by selected receivers. A processing system computes at least one of an absolute six degree offset or a relative six degree offset between the faces. The offset information is then used to achieve a desired alignment between the face of the first module and the face of the second module.

    • A configurable self-identifying workpiece transport system is described for moving an associated workpiece relative to a plurality of associated workpiece functional units selectively performing operations on the associated workpiece. The transport system includes a plurality of transport modules and a control unit. The plurality of transport modules are disposed in selected positions relative to the associated workpiece functional units, and each of the plurality of transport modules stores identification data and functionality data specific to the transport module. The control unit includes an automatic identification system in communication with each of the plurality of transport modules for retrieving the identification data and the functionality data from each of the plurality of transport modules and generating an itinerary for moving the associated workpiece relative to the workpiece functional units. Each of the plurality of transport modules includes a local communication circuit adapted to selectively communicate with adjacent transport modules. In one embodiment, the control unit is distributed among the plurality of transport modules and in another embodiment, a global system bus is provided by a central control unit for communicating with each of the plurality of transport modules through the global bus. The local communication circuit includes photo optic devices and the global system bus uses a two wire interface.
    • 描述了可配置的自识别工件传送系统,用于相对于多个相关联的工件功能单元移动相关联的工件,其选择性地对相关工件进行操作。 传送系统包括多个传送模块和控制单元。 多个传送模块相对于相关联的工件功能单元设置在选定位置,并且多个传送模块中的每一个存储特定于传送模块的识别数据和功能数据。 控制单元包括与多个传输模块中的每一个通信的自动识别系统,用于从多个传输模块中的每一个检索识别数据和功能数据,并产生用于相对于工件功能单元移动相关工件的行程 。 多个传输模块中的每一个包括适于选择性地与相邻传输模块通信的本地通信电路。 在一个实施例中,控制单元分布在多个传输模块中,在另一个实施例中,全局系统总线由中央控制单元提供,用于通过全局总线与多个传输模块中的每一个进行通信。 本地通信电路包括光电设备,全局系统总线使用双线接口。

    • Respective coordinators are spawned or activated to coordinate activities with regard to respective tasks. Where the respective tasks require cooperative efforts of a plurality of controllers, the respective coordinators ensure cooperative efforts by generating and communicating cooperative commands to the plurality of controllers. The coordinators may act as clearinghouses for system data, selectively requesting and relaying system information to appropriate controllers. For example, a document processing system activates respective coordinators for respective sheets of print media. The respective coordinators orchestrate the transportation of the sheets by sequentially orchestrating the activities of sequentially selected pluralities of transportation actuator controllers. Selected sheet position information from sensors and/or from models maintained by the actuator controllers may be relayed by the coordinators to selected actuator controllers as appropriate to the sheet transportation tasks.
    • 产生或激活相应的协调员,以协调相关任务的活动。 在各个任务需要多个控制器的协同努力的情况下,各个协调器通过生成并向多个控制器传送协作命令来确保合作努力。 协调员可以充当系统数据的清算所,选择性地请求和将系统信息中继到适当的控制器。 例如,文档处理系统激活相应的打印介质的协调器。 相应的协调员通过顺序地编排顺序选择的多个运输执行器控制器的活动来协调运输。 来自传感器和/或由致动器控制器维护的模型的选择的纸张位置信息可以由协调器被中继到选择的执行器控制器,以适合于纸张传送任务。

    • Large-area ICs (e.g., silicon wafer-based solar cells) are produced by positioning a mask between an extrusion head and the IC wafer during extrusion of a dopant bearing material or metal gridline material. The mask includes first and second peripheral portions that are positioned over corresponding peripheral areas of the wafer, and a central opening that exposes a central active area of the wafer. The extrusion head is then moved relative to the wafer, and the extrusion material is continuously extruded through outlet orifices of the extrusion head to form elongated extruded structures on the active area of the wafer. The mask prevents deposition of the extrusion material along the peripheral edges of the wafer, and facilitates the formation of unbroken extrusion structures. The mask may be provided with a non-rectangular opening to facilitate the formation of non-rectangular (e.g., circular) two-dimensional extrusion patterns.
    • 通过在掺杂剂轴承材料或金属网格线材料的挤出期间将掩模定位在挤出头和IC晶片之间来制造大面积IC(例如,基于硅晶片的太阳能电池)。 掩模包括位于晶片的相应周边区域上的第一和第二外围部分以及暴露晶片的中心有效区域的中心开口。 然后挤出头相对于晶片移动,并且挤出材料通过挤出头的出口连续挤出,以在晶片的有效区域上形成细长的挤出结构。 掩模防止挤出材料沿着晶片的周边边缘沉积,并且有助于形成不间断的挤出结构。 掩模可以设置有非矩形开口,以便于形成非矩形(例如圆形)二维挤出图案。
