    • A method and system for the capture of data files transmitted over a wired network by a data traffic generator. The mapping and/or translation of network addressing data contained within the captured data frames is such that the frames, when transferred over the wireless medium, appear to have originated from one of a population of emulated wireless stations. The mapping and/or translation of network addressing data contained in data frames received over the wireless medium directed to a specific emulated wireless station is such that the frames, when transmitted over the wired network, appear to be destined for the data traffic generator. The mapping and/or translation function is applied as frames traverse the boundary between the external data source network interface and the wireless network interface.

    • An induction furnace capable of operation at temperatures of over 3100° C. has a cooling assembly (60), which is selectively mounted to an upper end of the furnace wall (76). The cooling assembly includes a dome (62), which is actively cooled by cooling water coils (68). During the cool-down portion of a furnace run, cooling initially proceeds naturally, by conduction of heat away from the hot zone through a furnace insulation layer (58). Once the temperature within the furnace hot zone (20) reaches about 1500° C., a lifting mechanism (80), mounted to the dome, raises a cap (16) of the furnace slightly, allowing hot gases from the hot zone to mix with cooler gas in the dome. This speeds up cooling of the hot zone, reducing cool-down times significantly, without the need for encumbering the furnace itself with valves or other complex cooling mechanisms which have to be replaced periodically. The life of a graphite furnace susceptor (10) at the high operating temperature is increased by surrounding the susceptor with a barrier layer (40) of flexible graphite, which inhibits evaporation of the graphite. Additionally, witness disks (154), placed within the susceptor, provide an accurate temperature profile of the hot zone.
    • 能够在超过3100℃的温度下操作的感应炉具有冷却组件(60),其被选择性地安装到炉壁(76)的上端。 冷却组件包括由冷却水盘管(68)主动冷却的圆顶(62)。 在炉膛的冷却部分期间,冷却最初自然地通过来自热区的热传导通过炉绝缘层(58)。 一旦炉热区(20)内的温度达到约1500℃,安装在穹顶上的提升机构(80)稍微升高炉膛(16),允许来自热区的热气混合 在圆顶中有较冷的气体。 这加快了热区的冷却,显着降低了冷却时间,而不需要用阀或其他必须定期更换的复杂冷却机构来堵住炉本身。 通过用柔性石墨的阻挡层(40)围绕基座来增加石墨炉基座(10)在高工作温度下的寿命,这抑制了石墨的蒸发。 此外,放置在基座内的见证盘(154)提供热区域的精确温度分布。

In addition, the cartridge also includes a second barrier positioned adjacent to the outlet port and a second sealing member moveable between the piston and the second barrier, wherein the second sealing member seals the outlet port when positioned adjacent thereto but allows the fluid to pass through the outlet port when positioned adjacent to the second barrier.

    • A method and computer system for efficiently accessing resources in a multiprocessor computer system. Multiple resources are grouped into nodes and system resource descriptors are maintained as data structures. The method incorporates traversing a data structure to efficiently allocate resources within a grouping of nodes. Each node in the system is assigned a node identifying number. This number identifies a node location within a multiprocessor and is used to determine latency between nodes, either through an average latency table or a system interconnect connection table. The data structure comprises secondary data structures therein for storing processor, bus, memory and shared cache information. The data structure includes pointers to each of the secondary data structures. In addition, each node or grouping of nodes may include subnodes. As such, the system provides for a method of recursively accessing additional data structure levels for each level of nodes and/or subnodes in the system. In addition to the data structure and the secondary data structure, the system includes a memory map in the form of a data structure. This data structure stores information as to which node a given block of memory address space is located in. In addition, there is a flag for each memory block indicating whether the memory address is parity or error correcting code (ECC), or neither parity nor ECC protected. This flag is in the form of two bits for indicating the level of memory protection provided to a specific block of memory address. Accordingly, storing the system architecture information in a data structure format provides for an efficient method of accessing system resources and determining latency for specific processes and access patterns.
    • 一种用于在多处理器计算机系统中有效地访问资源的方法和计算机系统。 多个资源被分组成节点,系统资源描述符被保存为数据结构。 该方法包括遍历数据结构以在节点分组内有效地分配资源。 为系统中的每个节点分配一个节点标识号。 该数字标识多处理器内的节点位置,用于通过平均延迟表或系统互连连接表来确定节点之间的延迟。 数据结构包括用于存储处理器,总线,存储器和共享高速缓存信息的二次数据结构。 数据结构包括指向每个次要数据结构的指针。 另外,每个节点或节点分组可以包括子节点。 因此,该系统提供递归地访问系统中每个级别的节点和/或子节点的附加数据结构级别的方法。 除了数据结构和二次数据结构之外,系统还包括数据结构形式的存储器映射。 该数据结构存储关于给定的存储器地址空间位于哪个节点的信息。另外,每个存储器块都有一个标志,指示存储器地址是奇偶校验还是纠错码(ECC),或者不是奇偶校验 ECC保护。 该标志是两位的形式,用于指示提供给特定存储器地址块的存储器保护级别。 因此,以数据结构格式存储系统架构信息提供访问系统资源并确定特定进程和访问模式的等待时间的有效方法。

    • Disclosed is a system, method, and computer program product for canceling ambient noise in a portable mobile communications device that is coupled with a standard non-noise canceling headset assembly. The portable mobile communications device receives detected ambient noise from the headset assembly microphone and creates a noise canceling ambient noise sound wave that is 180° out of phase with the ambient noise sound wave. The noise canceling ambient noise sound wave is then combined with an intended sound wave such as music or speech. The combined noise canceling ambient noise sound wave and intended sound wave are then forwarded to the headset assembly such that the noise canceling ambient noise sound wave negates the ambient noise present at the headset assembly during playback of the intended sound wave. Noise canceling can be achieved using hardware filters or via a noise canceling software application within the portable mobile communications device.
