    • In illustrative implementations of this invention, interferential stimulation is precisely directed to arbitrary regions in a brain. The target region is not limited to the area immediately beneath the electrodes, but may be any superficial, mid-depth or deep brain structure. Targeting is achieved by positioning the region of maximum envelope amplitude so that it is located at the targeted tissue. Leakage between current channels is greatly reduced by making at least one of the current channels anti-phasic: that is, the electrode pair of at least one of the current channels has a phase difference between the two electrodes that is substantially equal to 180 degrees. Pairs of stimulating electrodes are positioned side-by-side, rather than in a conventional crisscross pattern, and thus produce only one region of maximum envelope amplitude. Typically, current sources are used to drive the interferential currents.
    • 在本发明的说明性实施中,干涉刺激精确地指向脑中的任意区域。 目标区域不限于电极正下方的区域,但可以是任何浅表,中等深度或深度的大脑结构。 通过定位最大包络振幅的区域以使其位于目标组织处来实现靶向。 通过使至少一个电流通道反相,即,至少一个电流通道的电极对在两个电极之间具有基本上等于180度的相位差,电流通道之间的泄漏大大减少。 成对的刺激电极并排放置,而不是以传统的十字形图案,因此只产生一个最大包络振幅的区域。 通常,电流源用于驱动干扰电流。

    • An optical receiver includes a cascade of optical filtering elements, each of which selects spectral components from incoming optical signals at a wavelengths aligned to filter passbands. The selected spectral components may be optically combined to form k pairs of intermediary signals, where k= log2(M). By comparing the k pairs of intermediary signals, k bits of a digital signal representing the incident signal may be generated. The filtering elements may be configured to perform demultiplexing and demodulation simultaneously, increasing functionality and reducing excess losses. The filtering elements may also be tuned so that the optical receiver may be reconfigured to accommodate different combinations of wavelengths and modulation formats, such as wavelength division multiplexed (WDM) on off keying (OOK), M-ary orthogonal formats including frequency shift keying (FSK) and pulse position modulation (PPM), differential phase shift keying, and hybrid combinations - providing rate and format flexibility and WDM scalability.
    • 一种光学接收器包括级联的光学滤波元件,其中的每一个从对准的波长的输入光信号中选择光谱分量以对通带进行滤波。 所选择的频谱分量可以被光学组合以形成k对中间信号,其中k = log2(M)。 通过比较k对中间信号,可以生成表示入射信号的数字信号的k位。 滤波元件可以被配置为同时执行解复用和解调,增加功能并减少额外损耗。 滤波元件也可以被调谐,使得光接收机可以被重新配置以适应波长和调制格式的不同组合,例如波分多路复用(WDM)开关键控(OOK),M元正交格式,包括频移键控( FSK)和脉冲位置调制(PPM),差分相移键控和混合组合 - 提供速率和格式灵活性以及WDM可扩展性。
