    • The present invention is a collapsible lighting fixture comprising a central support member having a first end engaged with abase and a second end. The lighting fixture further comprises an arm assembly removably engaged with the central support member. The arm assembly comprises eight arm members. The arm assembly is moveable between an open and a closed or collapsed position. In the open position, the first, second, third, and fourth arm members are substantially perpendicular to the fifth, sixth, seventh, and eighth arm members. In the closed position, the first, second, third, and fourth arm members are substantially less than perpendicular to the fifth, sixth, seventh, and eighth arm members. The lighting fixture further comprises a plurality of light holders removably engaged with the upper end of the central support member and arm members.
    • 本发明是一种可折叠的照明器具,其包括具有与底部接合的第一端和第二端的中心支撑构件。 照明器具还包括可移除地与中心支撑构件接合的臂组件。 臂组件包括八个臂构件。 臂组件可在打开和关闭或折叠位置之间移动。 在打开位置,第一,第二,第三和第四臂构件基本上垂直于第五,第六,第七和第八臂构件。 在关闭位置,第一,第二,第三和第四臂构件基本上小于垂直于第五,第六,第七和第八臂构件。 照明器具还包括可拆卸地与中心支撑构件和臂构件的上端接合的多个灯座。

    • A system and method of calibration, screening, and compensation is presented for multiple gray-level digital presses. Unequal quantization of the input range is employed with compensated overlapping of sub-ranges. Multiple instances of bi-level screening algorithms, tone modification functions, and a recombination algorithm are employed to produce calibrated screening on individual tone ranges. The method works with any bi-level screening algorithm and devices with any number of gray-levels. Quality imaging results from high detail, high tonal accuracy, low screening noise, and lack of printed artifacts. Dynamic re-calibration is facilitated. The elimination of the constraint of evenly spaced gray-levels also has advantages of cost and yield for both print head fabricators as well as digital press manufacturers. Multiple implementations of the system and method are given for both hardware and software embodiments of the invention.
    • 针对多个灰度数字印刷机提出了校准,筛选和补偿的系统和方法。 使用子范围的补偿重叠的输入范围的不等量化。 采用双重层次筛选算法,色调修正函数和重组算法的多个实例来对单个色调范围进行校准筛选。 该方法适用于任何双层筛选算法和具有任意数量灰度级别的设备。 质量成像来自高细节,高音调精度,低筛选噪音和缺乏印刷伪影。 便于动态重新校准。 消除均匀间隔灰度的约束也具有打印头制造商以及数字印刷机制造商的成本和成品率的优点。 给出本发明的硬件和软件实施例的系统和方法的多个实现。
