摘要： Graphic arts method and apparatus for representation via display media of arbitrary two dimensional figures. The method and apparatus of the present invention convert raw figure data into a reduced data set which defines a two dimensional arbitrary shape, herein referred to as a curve series, whose edges are defined by second order parametric curves (24) such that the edges of the curve series closely approximate those of the figure represented by the raw data. The curve series data is converted for presentation on a display medium (30) of an image which closely approximates that of the figure.

摘要： A driving circuit for a gas-discharge display device (20) includes a pair of switching members (94, 144) and the secondary windings (92) of a transformer (118) wired in series with one of the switching members. The switching members in response to receiving out-of-phase control signals alternately apply a low voltage pulse to the display device. The secondary windings of the transformer output continuously a high voltage pulse in phase with one of the switching members. Upon the generation of appropriate control signals enabling the operation of the switching members, a voltage of sufficient magnitude is applied to selected cell segments in the display device to fire the cells. The transformer together with the low voltage pulses are driven by a high frequency clock to provide a high intensity display operation.

摘要： A circuit for driving a gas-discharge device wherein discharge cells (120) each have a column electrode (28) and a segment electrode (26), includes a transformer (80) whose secondary winding (86) provides operating voltages for application to the electrodes. In operation, the secondary winding (86) is arranged during first time intervals to supply to the column electrodes (28) a first potential while a reference potential is applied to the segment electrodes (26). During second time intervals, the secondary winding (86) is arranged to supply to selected segment electrodes (26) a second potential, the reference potential being applied to selected column electrodes (28). Cells including selected column and segment electrodes are repeatedly ignited. A voltage regulator circuit (196) is coupled to the secondary winding (86).
