    • A patient alignment device includes a table and a rotatable member positioned to rotate relative to the table. The rotatable member may be a head-support plate or a board which supports substantially all of a patient's body. A motor moves the board or plate so as to align the patient's body, or a part of the body, in a desired direction. The board may be formed in two segments, the segments being selectively connectable to each other, the segments also being selectively connectable to the table by pins, at various possible pivot points. Positioning of the pins determines the mode of rotation of the board. The invention allows an operator to align the patient's body with precision, by remote control, and without interrupting the medical procedure.

    • The present discloses a method and a device for biogenic waste, or bio-waste treatment, and said method is as follows: Firstly, the biogenic waste is evenly mixed with water vapor, or steam, heating and pressurizing so that the temperature reaches 130-190° C. and the pressure reaches 1.5-1.9 MPa after mixture, and this state is maintained for 1-25 minutes; Then, the pressure of the mixture of said biogenic waste and water vapor is reduced to normal pressure, such as atmospheric pressure so as to conduct low-molecularization, such as decreasing or reduction of molecular weight of the biogenic waste to obtain a low-molecularized mixture, such as a low molecular weight mixture; finally, the low-molecularized mixture, such as low-molecular weight mixture is separated so as to obtain the final products. Said device includes reaction vessel, stirring device, vapor input device, pressure-reducing regulator and separation device.

    • Techniques for suppressing large echo due to nonlinearity, instable adaptive filter, and so on. An echo cancellation system includes an echo canceller unit, a nonlinear echo detection unit, and a nonlinear echo suppression unit. The echo canceller unit (e.g., an adaptive filter) receives a reference signal and a near-end signal, derives an echo estimate signal based on the reference and near-end signals, cancels a portion of echo in the near-end signal based on the echo estimate signal, and provides an intermediate signal having residual echo. The nonlinear echo detection unit detects for large nonlinear echo in the echo estimate signal. The nonlinear echo suppression unit suppresses large nonlinear echo in the first intermediate signal based on a variable gain, which may be adjusted lower if large nonlinear echo is detected and higher otherwise.
    • 用于抑制由于非线性引起的大回波的技术,不稳定的自适应滤波器等。 回波消除系统包括回波消除单元,非线性回波检测单元和非线性回波抑制单元。 回波消除器单元(例如,自适应滤波器)接收参考信号和近端信号,基于参考和近端信号导出回波估计信号,基于近端信号抵消近端信号中的一部分回波 回波估计信号,并提供具有残余回波的中间信号。 非线性回波检测单元检测回波估计信号中的大非线性回波。 非线性回波抑制单元基于可变增益来抑制第一中间信号中的大的非线性回波,如果检测到大的非线性回波,则其可以被调低,否则更高。
