    摘要： A system includes an identification circuit, a grid antenna, a receiver, and a processor. The identification circuit includes resonant circuits formed on a substrate within a perimeter. Identification may be based on a quantity or physical arrangement of detected resonant circuits within the perimeter. One resonant circuit provides a reference signal. Any resonant circuit may be tuned in accordance with the reference signal by the addition or subtraction of reactance formed on the substrate. A capacitance of a first group of capacitors located outside a turn of an inductor is roughly equal to a capacitance of a second group of capacitors located inside the turn. Any resonant circuit may also be tuned by affixing a resonance modifying element, for example a sticker, to the identification circuit. The grid antenna provides antenna field patterns, one for each cell location. The receiver communicates with the identification circuit via the grid antenna. The processor controls the receiver according to a method including: (a) detecting a first signal at a first grid location; (b) determining an offset as a difference between a frequency of the first signal and a predetermined frequency; (c) detecting a second signal at a second grid location; (d) determining an identification in accordance with the first and second locations, the second signal, the offset determined in step (b), and any offset accomplished by a sticker; and (e) determining an orientation in accordance with the first and second grid locations.

    摘要翻译： 系统包括识别电路，网格天线，接收器和处理器。 识别电路包括在周边的基板上形成的谐振电路。 识别可以基于周边内检测到的谐振电路的数量或物理布置。 一个谐振电路提供参考信号。 任何谐振电路可以通过加法或减去形成在基板上的电抗来根据参考信号进行调谐。 位于电感线圈外部的第一组电容器的电容大致等于位于转弯内部的第二组电容器的电容。 也可以通过将谐振修改元件（例如贴纸）附加到识别电路来调谐任何谐振电路。 网格天线提供天线场模式，每个小区位置一个。 接收机通过网格天线与识别电路进行通信。 处理器根据一种方法控制接收机，包括：（a）在第一网格位置检测第一信号; （b）将偏移量确定为所述第一信号的频率与预定频率之间的差; （c）在第二格栅位置处检测第二信号; （d）根据第一和第二位置确定标识，第二信号，在步骤（b）中确定的偏移量以及由贴纸完成的任何偏移; 和（e）根据第一和第二网格位置确定取向。

    摘要： A scalable radar signal processing system for processing data between a data source and a receiving terminal, in which a bus system is connected in parallel on at least one DSP (Digital Signal Processor) node, to a corresponding number of standard DSP cards as well as components for user data delivery and for user data collection. Each DSP node is operated with the same software and all the signal processing algorithms are executed on a user data component assigned to the corresponding node.
