    • The system includes a current injection device in electrical communication with the switch mode power supply. The current injection device is positioned to alter the initial, non-zero load current when activated. A prognostic control is in communication with the current injection device, controlling activation of the current injection device. A frequency detector is positioned to receive an output signal from the switch mode power supply and is able to count cycles in a sinusoidal wave within the output signal. An output device is in communication with the frequency detector. The output device outputs a result of the counted cycles, which are indicative of damage to an a remaining useful life of the switch mode power supply.

    • A low power circuit and method for detects in-situ failures or precursors to failures in solder-joint networks on actual operational devices and packages in the field. An amplifying detector such as provided by a common-gate transistor sources current to the network to generate a signal voltage and a reference voltage that is sensitive to the low voltage applied to the other side of the network. Generation of this self-adjusting reference voltage makes the detection circuit insensitive to the network low-voltage. Additional power savings and performance gains can be provided with the addition of a differential amplifier to set a fixed bias point and a level shifter to cancel noise. The detected failure or precursor of a selected monitor solder-joint network(s) is an indicator of the integrity of other operational solder-joint networks in the package, on the PWB or between PWBs.
    • 一种低功率电路和方法,用于在现场的实际操作设备和封装上检测原位故障或焊接网络故障的前兆。 诸如由公共栅极晶体管提供的放大检测器将电流源流到网络以产生对施加到网络的另一侧的低电压敏感的信号电压和参考电压。 产生这种自调节参考电压使得检测电路对网络的低电压不敏感。 通过添加差分放大器来设置固定偏置点和电平移位器来消除噪声,可以提供额外的功率节省和性能增益。 检测到的所选监测器焊点网络的故障或前体是PWB或PWB之间的封装中其他操作焊点网络的完整性的指示。

    • Machine-implemented text/graphics formatting is based upon a logical page area on a presentation-receiving medium, such as a CRT face, sheet of paper and the like. Named text and graphics receiving areas are selectively assignable to the logical pages of a document being formatted for visual presentation and are addressable and formattable independent of other formatting in any logical page. The named areas are machine defined such that one area can have portions thereof automatically assigned to and presented with any arbitrary number of logical pages. Such areas are managed in a text formatting machine to facilitate formatting headers based upon text contained in a succession of logical pages that are outside the named area. A first class of such named areas is placed upon the page when formatting to the page is ended, while a second class of such named areas is placed on the page in response to a command. The placement of the second class on a page can result in starting formatting new pages. Bleed tabs, annotations, and other typographic niceties are machine formattable using such named areas.

    • Text and graphics are justified along one physical dimension to a predetermined line of justification. A plurality of physical parameters are employed in the justification, each of the parameters is assigned a compression and an expansion adjustment ratio. Such ratios define the maximum adjustment range of each of the parameters. A priority of adjustment is assigned to each of the parameters such that one parameter being adjusted and capable of meeting justification needs is adjusted to the exclusion of all other possible parameter adjustments. In vertical justification of a plurality of columns, text distribution precedes the vertical adjustment. For such vertical justification, the priority of adjustment is based upon natural text/graphics breaks; top priority is use of lead outs, second is skips, third is spaces and last is textual adjustments. Justification is preferably proportional, i.e., the ratios are adjusted when the maximum permitted adjustment is not required for justification. For horizontal justification, similar ratio selections apply.
    • 文本和图形沿着一个物理维度被合理化为预定的对齐线。 在对齐中使用多个物理参数,每个参数被分配压缩和扩展调整比。 这些比率定义了每个参数的最大调整范围。 调整优先级被分配给每个参数,使得被调整并且能够满足调整需求的一个参数被调整为排除所有其他可能的参数调整。 在多个列的垂直对齐中,文本分布先于垂直调整。 对于这种垂直的理由,调整的优先次序是基于自然文本/图形中断; 优先使用铅笔,二是跳过,第三是空格,最后是文字调整。 理由最好是成比例的,即当调整不需要最大允许调整时调整比率。 对于水平对齐,适用比例选择。

    • The present invention provides a frequency-sampling circuit and method for characterizing a health condition of a test unit attached to a power supply. The frequency-sampling circuit is connected externally to the test unit. The circuit comprises an inductor and a capacitor connected in series at an output. When switched, the circuit resonates with an AC loop current to produce a damped-frequency response at the output. Frequency measurements of this response are processed to generate SoH or RUL estimates for the test unit. The voltages applied within the frequency-sampling circuit are limited, which in turn limits the AC loop current to avoid loading the power supply. Incorporating the inductance and capacitance with in the frequency-sampling circuit allows the circuit to be configured for different classes of test units having a wide range of characteristic impedances.
