    • A system and method for selecting redundant rows and columns of memory devices includes a column select steering circuit to couple column select signals from a column address decoder to an array of memory cells. The system and method also includes a fuse banks for programming respective addresses of up to two defective columns that are to be repaired. The programmed addresses are applied to a defective column decoder that determines which column select signal(s) should be shifted downwardly and which column select signal(s) should be shifted upwardly. The column select steering circuit responds to signals from the defective column decoder to shift the column select signals downwardly or upwardly. The column select signal for the lowest column is shifted downwardly to a redundant column, and the column select signal for the highest column is shifted upwardly to a redundant column.
    • 用于选择存储器件的冗余行和列的系统和方法包括:列选择转向电路,用于将列选择信号从列地址解码器耦合到存储器单元阵列。 该系统和方法还包括用于编程待修复的多达两个缺陷列的相应地址的熔丝组。 编程的地址被应用于有缺陷的列解码器,该解码器确定哪个列选择信号应该被向下移位,哪个列选择信号应向上移位。 列选择转向电路响应来自故障列解码器的信号,以向下或向上移动列选择信号。 最低列的列选择信号向下移动到冗余列,最高列的列选择信号向上移动到冗余列。

    • The invention relates to a dispensing machine for printed publications. The vending machine allows to dispense one copy at a time by providing a metering break next to a dispensing channel. The vending machine has a hollow housing, within which a detachable module is slidably mounted. An operational portion of the machine includes a motor controlled by a microchip that constantly adjusts the speed of the motor depending on the thickness of the dispensed publication. A paper speed sensor sends a signal to the motor to facilitate adjustment in the speed control. Printed publications rest in an upright position on moving endless belts that are connected to the motor for advancing the publications toward the dispensing channel. One or more torsion springs support the front face of the forwardmost publication immediately prior to dispensing to prevent premature opening of an unfolded edge of the publication and jamming of the dispensing channel.
    • 本发明涉及一种用于印刷出版物的分配机。 自动售货机允许通过在分配通道旁边提供计量中断来一次分配一个副本。 自动售货机具有中空的外壳,可拆卸的模块可滑动地安装在该壳体内。 机器的操作部分包括由微芯片控制的电动机,其根据所分发的出版物的厚度不断地调节电动机的速度。 纸张速度传感器向电机发送信号,以方便调速。 印刷出版物在连接到电动机的移动的环形带上处于直立位置,用于将出版物推向分配通道。 一个或多个扭转弹簧在分配之前立即支撑最前面的出版物的前表面,以防止出版物的展开边缘的过早打开和分配通道的卡住。

    • A millimeter wave imaging system. The system includes one or more millimeter wave frequency scanning antenna for collecting frequency dependent beams of millimeter wave radiation from a narrow one-dimensional field of view and millimeter wave amplifier components for amplifying the millimeter wave radiation collected by each antenna. The system includes a beam-former that separates the amplified radiation to produce frequency dependent signals corresponding to the frequency dependent beams. The beam-former includes delay lines, a millimeter wave lens, and an array of millimeter wave power detectors for detecting the power in each frequency dependent beam. A sampling circuit reads out the frequency dependent signals to produce a one-dimensional image of the antenna field of view. A two dimensional image of a target may be obtained by moving the target (or having the target move) across the field of view of the scanning antenna or by moving the antenna in order to scan its line of focus over the target. In preferred embodiments a 2×2 Dicke switch is provided to permit sampling a reference thermal source for gain control while continuing to collect image information. This 2×2 Dicke switch provides a square root of 2 improvement in temperature sensitivity over a single receiver version. Preferred embodiments also include features for focusing the antenna within a range of about 5 feet to infinity.

    • A passive millimeter wave imaging system that includes at least one millimeter wave frequency scanning antenna and multiple beam formers collecting narrow beams of millimeter wave radiation from a two-dimensional field of view. The collected radiation is amplified and separated into bins corresponding to various vertical and horizontal beam orientations. In a preferred embodiment each beam formers include one phase processor with 232 inputs and 192 outputs that feed into 192 frequency processors. In another preferred embodiment each beam formers include one phase processor with 232 inputs and 72 outputs that feed into only 24 frequency processors. In this second embodiment 26 3×1 PIN diode switches sequentially switch one of three phase processor outputs into a frequency processor. As in the first embodiment two dimensional images of a target are obtained by the simultaneous detection of signal power within each beam and converting it into pixel intensity level. This embodiment is a lower cost and lower weight unit but operates at a rate of 10 frames per second with some reduction in the horizontal field of view.
