    • A system and method that improve service and device discovery in a UPnP-based wireless communication network and avoids unnecessary broadcast messages on a MAC sublayer of a DLC layer caused by UPnP multicast messages on an IP layer by intercepting UPnP multicast messages in a network protocol stack below the IP layer. A module intercepts multicast UDP packets destined to a UPnP IP multicast address and port, the multicast UDP packets containing UPnP packets as payload. The module executes DLC/MAC-based service discovery functions to perform wireless network-specific device discovery and to find UPnP-enabled devices in the wireless communication network. Once a wireless network device discovery has returned nodes that fulfill criteria given in the search, the module uses unicast DLC/MAC messages to send UPnP packets to only those nodes that are UPnP-enabled and whose device type matches the respective UPnP device type sought.
    • 一种改进在基于UPnP的无线通信网络中的服务和设备发现的系统和方法,并且通过拦截网络协议栈中的UPnP多播消息来避免由IP层上的UPnP多播消息引起的DLC层的MAC子层上的不必要的广播消息 在IP层之下。 模块拦截发往UPnP IP组播地址和端口的组播UDP数据包,其中包含UPnP数据包的组播UDP数据包作为有效载荷。 该模块执行基于DLC / MAC的服务发现功能来执行无线网络专用设备发现,并在无线通信网络中查找支持UPnP的设备。 一旦无线网络设备发现已经返回满足搜索中给出的标准的节点,则该模块使用单播DLC / MAC消息将UPnP分组发送到仅具有UPnP的那些节点,并且其设备类型与所寻求的各种UPnP设备类型匹配。

    • Printing plate production apparatus wherein a latent image is formed at the surface of photoconductive insulating sheet, either by an optical system for effecting sheet exposure or by a laser emission scanning system which constitutes the terminal of a facsimile transmission system, this latent image is developed by toner particles, for example, which are applied on, but not fixed on the photoconductive sheet, the developed image is temporarily transferred onto a printing plate with which the photoconductive sheet is brought into pressure contact, and the printing plate carrying the developed image is exposed to light which may effect chemical changes in the printing plate to harden portion thereof unprotected by toner particles after which the printing plate receives treatment to remove toner particles and unhardened portions thereof. In the means of the invention a sheet carrying a developed image initially transmitted by a single facsimile transmission system may be employed as a master copy which is mounted in the exposure system and serves in production of a plurality of identical printing plates.
    • 通过用于实现片材曝光的光学系统或者构成传真传输系统的终端的激光发射扫描系统,在光电导绝缘片的表面上形成潜像的印版生产设备,该潜像由 将显影图像施加在但不固定在光电导片上的调色剂颗粒暂时转印到与感光体压力接触的印刷版上,并且承载显影图像的印版露出 可能影响印版中的化学变化以使未被调色剂颗粒保护的部分硬化,之后印版接受处理以除去调色剂颗粒和未硬化部分。 在本发明的手段中,可以采用携带初始由单传真传送系统传送的显影图像的纸张作为安装在曝光系统中并用于生产多个相同印版的主复印件。
