A circuit for driving light emitting diodes with a precise amount of current in response to an input pulse is disclosed. The input pulse drives a transistor into saturation, and the collector current of this transistor is increased in value through the use of two cascaded multiplying current mirrors. The second current mirror directly drives the light emitting diodes.

The principles of the present invention relate to adaptively filtering outlines of typographic characters to simply representative control data. A filtering module receives a set of control points (and instructions for connecting the control points) representing a graphical object, such as, for example, a typographical character. The filtering module adaptively filters out some variations in the outline of the graphical object to reveal common edges of the outline. The filtering module generates...

A rule-based data processing apparatus includes a processor coupled with at least first and second stores. The first store holds respective defining rule-sets for two or more groups of agents. The second store holds data defining respective objects with associated qualifier terms. The first group, of agents defined as script agents, are arranged as a sequentially enabled chain, with one or more of the script agents including references to respective objects and specified qualifier terms. The sec...

An LED array circuit includes a number of series connected LED pairs, each pair including two parallel connected oppositely polarized LEDS. The array is coupled to a standard AC voltage source in series with an inductor L having Q>5 and a reactance which is equivalent to the resistance of a current limiting resistor. The use of an inductor in place of a resistor increases the efficiency of the array to approximately 80%. The efficiency of the array is increased even further by coupling a capa...
