    • A system and method are disclosed for sending and receiving RapidIO traffic to/from a RapidIO system, network or device, independent of the system, network or device. For example, a RapidIO test adapter (RTA) system is disclosed that facilitates the accessing and testing of an embedded system or device with a RapidIO interface, RapidIO network switch, and/or an entire RapidIO network. The RTA system provides a “known good” RapidIO endpoint and can issue and receive RapidIO transaction requests and responses. Also, the RTA system provides a hardware and software architecture that facilitates the programming of external systems so as to allow them to exercise control over the issuance and reception of RapidIO transaction requests and responses, without needing detailed knowledge of the RapidIO protocol or hardware used to implement the RapidIO endpoint involved. Also, the RTA system provides a plurality of independent RapidIO endpoints, which can support a wide variety of test cases without the need for additional RapidIO devices. As such, the RTA system provides physical test points on each RapidIO interface that can be used to connect an embedded system or device to RapidIO protocol analyzer hardware. Furthermore, the RTA system allows a user to manually initiate RapidIO transactions via a web-based user interface, and also uses a simple TCP/IP protocol which an external host can use to send/receive RapidIO transactions, thereby reducing the time required to program custom tests. Also, the RTA system enables RapidIO operations to be initiated by embedded software that can provide human-to-machine and machine-to-machine interfaces suitable for performing both static and dynamic tests.
    • 公开了一种系统和方法,用于独立于系统,网络或设备,向RapidIO系统,网络或设备发送和接收RapidIO流量。 例如,公开了利用RapidIO接口,RapidIO网络交换机和/或整个RapidIO网络来访问和测试嵌入式系统或设备的RapidIO测试适配器(RTA)系统。 RTA系统提供了一个“已知的”RapidIO端点,可以发出和接收RapidIO事务请求和响应。 此外,RTA系统提供了便于外部系统编程的硬件和软件体系结构,以便允许他们对RapidIO事务请求和响应的发布和接收进行控制,而无需使用RapidIO协议或硬件的详细知识 实现所涉及的RapidIO终端。 此外,RTA系统提供了多个独立的RapidIO端点,可以支持各种测试用例,而无需额外的RapidIO设备。 因此,RTA系统在每个RapidIO接口上提供物理测试点,可用于将嵌入式系统或设备连接到RapidIO协议分析仪硬件。 此外,RTA系统允许用户通过基于Web的用户界面手动启动RapidIO事务,并且还使用外部主机可用于发送/接收RapidIO事务的简单TCP / IP协议,从而减少编程所需的时间 定制测试。 此外,RTA系统使RapidIO操作能够由嵌入式软件启动,可以提供适合于执行静态和动态测试的人机界面和机器对机器接口。

    • An apparatus and method of printing images (10) onto a photosensitive media (140) using multiple reflective spatial light modulators. In the apparatus and method, illumination optics (25) uniformize and image light from at least one light source through polarization beamsplitting elements (80). The polarization beamsplitting elements (80) divide the illumination light into two polarization states. One polarization state of the illumination light illuminates the reflective spatial light modulators in a telecentric manner. The reflective spatial light modulators are addressed with image data signals. The reflective spatial light modulators modulate the polarized illumination light on a site by site basis and reflect the modulated light back through the polarized beamsplitting elements (80). The modulated light beams are combined to form an image, which is directed through a print lens (110) to expose a photosensitive media (140). The position of the spatial light modulators can be changed, and a new image can be printed.
