    • A system may include a printed circuit board, a first component located on the printed circuit board, the first component having a first unique identifier and a processor located on the printed circuit board, the processor including a one time programming section. The processor may acquire the first unique identifier from the first component and store the first unique identifier in the one time programming section during the first time initialization. Upon subsequent initializations, the processor may acquire the first unique identifier from the first component and compare the first unique identifier to the stored first unique identifier. The processor may allow the subsequent initializations to proceed if the first unique identifier matches the stored first unique. The processor may disallow the subsequent initializations from proceeding if the first unique identifier does not match the stored first unique identifier.
    • 系统可以包括印刷电路板,位于印刷电路板上的第一组件,第一组件具有第一唯一标识符和位于印刷电路板上的处理器,所述处理器包括一次性编程部分。 处理器可以从第一组件获取第一唯一标识符,并且在第一次初始化期间将第一唯一标识符存储在一次性编程部分中。 在随后的初始化时,处理器可以从第一组件获取第一唯一标识符,并将第一唯一标识符与存储的第一唯一标识符进行比较。 如果第一唯一标识符与存储的第一唯一标识匹配,则处理器可以允许继续进行初始化。 如果第一唯一标识符与存储的第一唯一标识符不匹配,则处理器可以禁止随后的初始化进行。

    • Disclosed are systems and methods which provide high bandwidth data communication with respect to a large coverage area using smart antenna and/or directional antenna (referred to herein as multi-beam antenna) technology. Circuitry may be provided at a WLAN AP to provide selection of particular antenna beams used in the downlink and/or uplink, control of multicast transmission, control of unicast transmission, and to provide antenna pattern shaping techniques. Embodiments implement multi-beam antenna technology with little or no hardware modifications to AP circuitry. Other embodiments implement multi-beam technology using radio front-end and/or radio hardware modifications to AP circuitry. Various diversity techniques may be implemented, such as selection diversity, maximum ratio combining, and equal gain combing. To provide desired antenna pattern shaping, phase offsets with respect to a signal as transmitted in each antenna beam may be employed.

    • An integrated circuit device layout and a method for detecting mask data handling errors are disclosed in which integrated circuit device layout includes a device region in which operable circuitry is disposed. Integrated circuit device layout also includes a verification region in which verification elements are disposed. The verification elements include cells that are duplicates of at least some of the different types of cells in device region and can include structures that are duplicates of at least some of the types of structures in the device region. The patterns in verification region are used in the final verification process to identify mask data handling errors in a mask job deck. Because the patterns in verification region are easy to locate and identify, the time required to perform the final verification process is reduced and the chance of error in the final verification process is reduced.
