    • An embodiment of an apparatus includes a detector to receive a first input signal and a second input signal to provide a first error signal and a second error signal. A pulse width determination block receives the first and second error signals, as well as a digital oscillating signal, to output a first pulse width value and a second pulse width value, respectively. A pulse width accumulator accumulates the first and second pulse width values responsive to at least one cycle of the digital oscillating signal to provide a first accumulated value and a second accumulated value. An error generator provides an error value as a difference between the first accumulated value and the second accumulated value. The error value represents a pulse width difference between the first input signal and the second input signal indicative of a phase difference between the first input signal and the second input signal.

    • A circuit generates an output clock signal synchronized to an input clock signal. The circuit includes a reference clock port, a phase interpolator, and a phase controller. The reference clock port receives a reference clock signal. The phase interpolator generates the output clock signal that, as a function of a variable control value, is an interpolation between two reference phases. The reference phases are generated from the reference clock signal and have a reference frequency. The phase controller generates the variable control value providing a phase rotation rate. An output frequency of the output clock signal equals a sum of the reference frequency and the phase rotation rate. The output frequency matches an input frequency of the input clock signal.
    • 电路产生与输入时钟信号同步的输出时钟信号。 该电路包括参考时钟端口,相位内插器和相位控制器。 参考时钟端口接收参考时钟信号。 相位插值器产生作为可变控制值的函数的两个参考相位之间的内插的输出时钟信号。 参考相位由参考时钟信号产生并具有参考频率。 相位控制器产生提供相位旋转速率的变量控制值。 输出时钟信号的输出频率等于参考频率和相位旋转速率之和。 输出频率与输入时钟信号的输入频率相匹配。

    • A method and apparatus for curing large composite parts. The method utilizes a fiber metal mesh sheet (40) situated against a composite material(34) during a curing process. The fiber metal mesh sheet (40) provides a porous network for flow of the reaction by-products during a curing and vacuuming process, yet gives adequate structure to prevent both mark-off by vacuum ports (52, 70) and crushing of the porous network as a result of autoclave and vacuum pressure. External vacuum ports (52) are located in a bagging film (50) surrounding the composite material (34). Alternatively, vacuum ports (70) are located below the composite material (34). The use of the external vacuum ports (52), vacuum ports (70) located beneath the composite material (34), or both, shortens by-product flow path and provides adequate vacuum pressure over all areas of the composite material (34) to remove reaction by-products.

    • Disclosed are a method and apparatus for addressing a ferroelectric liquid crystal array where pixels are formed at the intersections of columns and rows of electrodes wherein one embodiment of a column write pulse sequence comprises four pulses- one a threshold pulse, two sub-threshold pulses and one zero pulse- all of equal width and within one unit at a time. In another embodiment a column write pulse sequence comprises five pulses- one a threshold pulse, three sub-threshold pulses and one zero pulse, with the threshold and zero pulses having equal widths and the three sub-threshold pulses having equal widths which is twice the width of the threshold pulses. In both embodiments, the same sequence of write pulses are used as row pulses but delayed or advanced to create electric fields of different directions to write a +1 or a -1 pixel depending upon whether or not the row pulse sequence is advanced or delayed. Also disclosed are non-writing pulse sequences to be addressed where a threshold field is undesirable.
