摘要： A network is protected against interruption of service while one or more faulty switches or optical fiber transmission lines are repaired or replaced, by an interconnecting configuration of small NnullN optical input/output switches, where N is 2 or greater than 2. The switches are configured among protection and working transmission lines. The small number of fibers for each switch improves repair and installation connection reliability and permits configurations that flexibly meet differing requirements. Also the fault is monitored with a fault check signal.
摘要翻译：通过小型NxN光输入/输出交换机（N为2或大于2）的互连配置，网络可以防止服务中断，而一个或多个故障交换机或光纤传输线路被修复或更换。这些交换机被配置在保护和工作传输线之间。每个开关的纤维数量少，可以提高维修和安装连接的可靠性，并允许灵活满足不同要求的配置。此外，故障通过故障检查信号进行监控。

摘要： We propose an extension of the view function, called a view with mask, where we can define a mask condition and values for each column that will be applied to the result of query execution. We also provide a set of query rewrite algorithms to implement a view with mask. Then, we define semantics for a selection condition on mask columns, an aggregation on mask columns, and external references for mask conditions. A view with mask can keep a security level, called inference-free against coloring, i.e., if an initial relation is inference-free against coloring, then a result of a query on the relation is also inference-free against coloring.
摘要翻译：我们提出了一个视图函数的扩展，称为具有掩码的视图，我们可以在其中定义一个掩码条件，并将每个列应用于查询执行结果的值。我们还提供一套查询重写算法来实现带有掩码的视图。然后，我们定义掩码列上的选择条件的语义，掩码列上的聚合以及掩码条件的外部引用。具有掩码的视图可以保持安全级别，被称为无推理的着色，即，如果初始关系对于着色是无意义的，则关于该关系的查询的结果也是无色的。

摘要： A assembler extended instruction set architecture ISA is formed from a current ISA to which is added new instructions. Assembly of source code listing of a mixture of current and new assembly language instructions is accomplished by preprocessing the source code to create a temporary file that contains the old instructions and data directives for each of the new assembly instructions that have, as the data arguments, the object code equivalent of such new instruction. The temporary file is then applied to the old assembler to produce, for each of the old assembly language instructions, the corresponding object code. The result, after linking, is an executable, machine language program for the new ISA.
摘要翻译：汇编器扩展指令集架构ISA由当前的ISA形成，并添加新的指令。通过预处理源代码来创建一个临时文件，其中包含用于每个新的汇编指令的临时文件，该临时文件包含作为数据参数的每个新的汇编指令，对象代码相当于这样的新指令。然后将临时文件应用于旧的汇编器，为每个旧的汇编语言指令产生相应的目标代码。结果，连接后，是新的ISA的可执行的机器语言程序。

摘要： A negative voltage generator for an integrated circuit includes a charge pump responsive to the current loading on its output terminal. The charge pump is connected to a comparator which compares the output node of the charge pump with a reference potential. The comparator provides an analog output signal to a variable frequency oscillator, which in turn controls the charge pump. Variations in current loading caused the comparator to make appropriate changes in the oscillation frequency.

摘要： A system and method for providing advertisements to a wireless remote display terminal. The terminal may display Internet web sites and other data while a viewer is also watching a television channel or performing other tasks. For example, a home entertainment center can include a television and an additional remote display terminal. Viewers can access information related to the television program on the remote display terminal. When the remote display terminal is turned on, a personalized advertisement is displayed to the viewer during the initialization process. The advertisement revenues can help offset the cost of the remote terminal to the viewer. The advertisements can be targeted to particular users by matching the advertisements to personal information obtained by surveys, past viewing and Internet history or third party sources such as magazine subscriptions.

摘要： Methods and apparatus for implementing a reduced cost HDTV/SDTV video decoder are disclosed. The described joint video decoder is capable of decoding HDTV pictures at approximately the resolution of standard definition television pictures and can be used to decode HDTV and/or SDTV pictures. The described video decoder may be used as part of a picture-in-picture decoder circuit for providing picture-in-picture capability without providing multiple full resolution video decoders. The reduction in decoder circuit complexity is achieved through the use of a plurality of data reduction techniques including the use of a preparser, downsampling, and truncating pixel values.
