    • A method and related bonding compositions for use in assembling a solid oxide fuel cell (“SOFC”) stack having thermally and chemically stable and electrically conductive bonds between alternating fuel cells and interconnect components in the stack. The improved method and materials allow for the assembly of solid oxide fuel cells having a stronger and more reliable bond with good electrical contact in situ between the SOFC interconnect layers (plates) and the electrodes. The bonding materials and method according to the invention provide good electrical performance while maintaining the mechanical and electrical integrity of SOFC stacks without requiring excessive mechanical compression of the stack as exemplified by prior art systems. The preferred bonding agents comprise a primary phase that provides the electrical conduction path during fuel cell operation, as well as the mechanical strength necessary to insure a reliable connection between the interconnect and the relevant anode or cathode surfaces of the fuel cell. Secondary phases can be added in small amounts to the primary phase to improve adhesion. An exemplary method according to the invention also contemplates various different steps for pre-treating the surfaces of the interconnect plates and electrodes to improve their surface bonding properties.
    • 一种用于组装固体氧化物燃料电池(“SOFC”)堆叠的方法和相关的粘合组合物,其在交替的燃料电池和叠层中的互连部件之间具有热和化学稳定且导电的结合。 改进的方法和材料允许组装固体氧化物燃料电池,其具有更强和更可靠的结合,在SOFC互连层(板)和电极之间原位具有良好的电接触。 根据本发明的接合材料和方法提供良好的电性能,同时保持SOFC堆叠的机械和电气完整性,而不需要堆叠的过度机械压缩,如现有技术系统所示。 优选的粘合剂包括在燃料电池操作期间提供导电路径的主相以及确保在互连和燃料电池的相关阳极或阴极表面之间的可靠连接所必需的机械强度。 次相可以少量添加到主相以改善粘附性。 根据本发明的示例性方法还考虑了用于预处理互连板和电极的表面以改善其表面粘合性质的各种不同步骤。

    • A method or device handles memory management faults in a device having a digital signal processor (“DSP”) and a microprocessor. The DSP includes a memory management unit (“DSP MMU”) to manage memory access by the DSP, and the DSP and the microprocessor access shared physical memory. Upon the DSP executing an instruction attempting to access a virtual address wherein the virtual address is invalid, a page fault interrupt is generated by the DSP MMU. A microprocessor interrupt handler in the microprocessor is activated in direct response to the page fault interrupt. Thereafter in the microprocessor, a translation lookaside buffer (“TLB”) entry is created in the DSP MMU, which includes a valid mapping between the virtual address and a page of physical memory. After creating the TLB entry, the microprocessor indicates to the DSP that the access by the DSP of the virtual address is completed.
    • 方法或设备处理具有数字信号处理器(“DSP”)和微处理器的设备中的存储器管理故障。 DSP包括一个内存管理单元(“DSP MMU”),用于管理DSP的存储器访问,DSP和微处理器访问共享的物理内存。 在DSP执行试图访问虚拟地址无效的虚拟地址的指令时,由DSP MMU产生寻呼故障中断。 微处理器中的微处理器中断处理程序是直接响应页错误中断而被激活的。 此后在微处理器中,在DSP MMU中创建翻译后备缓冲器(“TLB”)条目,其包括虚拟地址和物理存储器页之间的有效映射。 在创建TLB条目之后,微处理器向DSP指示DSP访问虚拟地址。
