    摘要： Fluid element device including fluid elements arranged in a matrix configuration having rows and columns with the level of fluid in each fluid element being controllable by electric force. The fluid elements include capillary tubes having electrode segments electrically insulated from one another such that each segments is receivable of a different voltage. A first voltage delivery circuit applies voltage to selected fluid elements in one or more rows of fluid elements and a second voltage delivery circuit applies voltage to selected fluid elements in one or more columns of fluid elements. The fluid level rises in the selected fluid elements to which voltage is applied by both the first and second voltage delivery circuits. The capillary tubes are structured and arranged such that the level of fluid in the selected elements can be retained independent of the application of voltage by the first and second voltage delivery circuits.

    摘要： An X-ray apparatus with an X-ray source for producing a beam of X-rays, an X-ray detector for detecting the beam, and an X-ray filter with filter elements. The X-ray filter is arranged between the X-ray source and the X-ray detector to attenuate the X-ray beam in each independent filter element individually. Each filter element can receive a liquid which is electrically conductive and X-ray absorbing, and is supplied via a transport channel, the X-ray absorptivity of each filter element being discretely adjustable by step-wise adjustment of the level of the liquid in each filter element. Each filter element includes a first electrode which is located in the wall of the filter element, on top of a substrate layer for applying an electric potential to the wall of the filter element. A second electric potential is applied to the liquid via a second electrode. Th first electrode is segmented in the longitudinal direction z of the filter element in order to achieve reproducible, step-wise filling of the filter element with the X-ray absorption liquid.

    摘要： A method for driving pixels in a display device with an image signal is disclosed wherein the image signal comprises grey level information of an image to be rendered by the display device. The method comprises: dividing the image signal into sections, each section having a duration of a section period; dividing the section period into a plurality of adjacent, weighted sub-section periods; selecting for each of the pixels to be driven during the section period a sequence of adjacent sub-section periods in dependence on the grey level information, the selectable sequences lacking a common starting and ending point; driving the pixels during the sequences adjacent sub-section periods. The method may be applied to displays driven by a pulse width modulated signal, such as sub-field as well as sub-line operated displays including plasma display panels, dynamic foil displays and passive displays.
