    • A signal equalizer that employs micro-electromechanical machine devices for the tap weight controllers. The equalizer includes a substrate on which is formed a forward transmission line rail and a return transmission line rail. A cantilever stanchion is also formed on the substrate that runs parallel with the transmission line rails. A series of spaced apart cantilevers are pivotally mounted to the cantilever stanchion, and extend over the transmission line rails to define a gap therebetween. A weight tap line is coupled to each cantilever, and is responsive to a DC weight signal that controls the position of the cantilever to set the gap between the cantilever and the transmission line rails. A distorted signal is coupled from the forward transmission line rail to the return transmission line rail through the cantilevers.

    • A configurable circuit array that includes a matrix of cells, where each cell includes interconnected analog and/or digital circuit elements. The cells are fabricated on a common semiconductor substrate, and are electrically isolated from each other. The circuit elements in the cells are electrically coupled to circuit elements in other cells, and are electrically coupled to bonding pads by coaxial transmission lines capable of transmitting extremely high frequency signals. The transmission lines include a center conductor and first and second shield conductors, where the shield conductors prevent cross-talk interference. The transmission lines extend vertically from the substrate until they are a suitable distances above the circuit elements in the cell. From there, the transmission lines extend horizontally relative to the substrate to the opposite end connection point, where they again extend vertically down to the substrate.

    • An optical device for use with an optical input beam comprises and optical thresholding device having a predetermined threshold level, and is positioned along an optical path defined by the propagation direction of the optical input beam. A source generates a control beam through the optical thresholding device, wherein if the combined intensity of the optical input beam and the control beam is large enough to exceed the threshold level of the thresholding device, the optical beam passes through he thresholding device. The thresholding device attenuates the optical beam as it passes therethrough. In a preferred embodiment, the optical thresholding device is a saturable absorber. When the device is configured as an optical comparator, the intensity of the optical input beam is large enough to exceed the threshold level of the thresholding device, the thresholding device saturates and turns transparent so that the control beam passes through the thresholding device as an optical indicator beam and the optical input beam passes through the thresholding device. When configured as an optical signal attenuator and the intensity of the optical input signal is negligible compared to that of the control beam the combined intensity of the optical input signal and the control beam do not saturate the thresholding device.
    • 用于光输入光束的光学装置包括具有预定阈值电平的光阈值装置,并且沿着由光输入光束的传播方向限定的光路定位。 源通过光阈值设备产生控制光束,其中如果光输入光束和控制光束的组合强度足够大以超过阈值设备的阈值电平,则光束通过阈值设备。 阈值装置在光束通过时衰减光束。 在优选实施例中,光阈值设备是可饱和吸收器。 当该设备被配置为光学比较器时,光输入光束的强度足够大以超过阈值设备的阈值电平,阈值设备饱和并变透明,使得控制光束作为光学器件通过阈值设备 指示光束和光输入光束通过阈值设备。 配置为光信号衰减器时,光输入信号的强度与控制光束的强度相比可忽略不计,光输入信号和控制光束的组合强度不会使阈值设备饱和。

    • An orthogonal pilot tone servo controller provides a servo control loop for each tap in a delay line processor where each servo acquires its independence from the other tap's servos utilizing an orthogonal code set modulated on top of the existing tap values. The orthogonal codes are attenuated in amplitude such that the code sets are transparent to the processed signals of interest, but the code's length enables each tap's servo controller to independently recover the tap's state from the aggregate of signals and codes through processing gain realized in each loop's recovery circuit. A plurality of taps can be thus be servo controlled simultaneously, providing for extremely wide bandwidth processes which can be performed accurately with digital controls.
