Abstract: In a backlight, for example, a pair of U-shaped discharge tubes are connected to connectors of a discharge tube lighting circuit. A secondary output voltage of a first transformer is applied to a first end of one U-shaped discharge tube via a power supply electrode. A secondary output voltage of a second transformer is applied to a first end of the other U-shaped discharge tube via a power supply electrode. A secondary output voltage of a third transformer is applied in common to the other (second) ends of the U-shaped discharge tubes via other power supply electrodes. The secondary output voltages of the first and second transformers are the same in polarity, and are opposite to the secondary output voltage of the third transformer in polarity.

Abstract: A driving arrangement for a plurality of light emitting diodes (LEDs), comprising a first power supply line (Vcc), a second power supply line (GND) and a set of signal lines (1a, 1b, 1c) for carrying brightness intensity and or chromatic information for the plurality of light emitting diodes (54).

In a second possible configuration of use for driving a “passive” source, the second power supply line (GND) is not used and the brightness of the light emitting diodes (54) is controlled by switching signals applied via the first power supply line (Vcc) and the set of signal lines (1a, 1b, 1c).

Abstract: A multi-frequency receiver for receiving plural frequencies of electromagnetic radiation (e.g., light) using a beam of charged particles shared between plural resonant structures. The direction of the beam of charged particles is selectively controlled by at least one deflector.

A second aspect herein provides for controlling the operation of a boost voltage applied to the lamp at start up. This control allows for adjusting the applied boost voltage to accommodate the changing characteristics of the lamp itself, and these adjustments can allow for extended life of the lamp.

The OLED display device has at least one of a common power bus line or a cathode bus line formed at a peripheral portion of the OLED display device. By forming a lower line when a gate electrode of a thin film transistor is formed, and forming an upper line connected to the lower line through a contact hole when source and drain electrodes of the thin film transistor are formed, a dual structure of lower and upper lines is formed. As such, the OLED display device can reduce the width of interconnections without a high voltage drop to thereby increase an emission area of a light emitting portion of the OLED display device.

Abstract: A device for generating atmospheric pressure cold plasma inside a hand-held unit discharges cold plasma with simultaneously different rf wavelengths and their harmonics. The device includes an rf tuning network that is powered by a low-voltage power supply connected to a series of high-voltage coils and capacitors. The rf energy signal is transferred to a primary containment chamber and dispersed through an electrode plate network of various sizes and thicknesses to create multiple frequencies. Helium gas is introduced into the first primary containment chamber, where electron separation is initiated. The energized gas flows into a secondary magnetic compression chamber, where a balanced frequency network grid with capacitance creates the final electron separation, which is inverted magnetically and exits through an orifice with a nozzle. The cold plasma thus generated has been shown to be capable of accelerating a healing process in flesh wounds on animal laboratory specimens.

Abstract: A system and method for containing plasma and forming a Field Reversed Configuration (FRC) magnetic topology are described in which plasma ions are contained magnetically in stable, non-adiabatic orbits in the FRC. Further, the electrons are contained electrostatically in a deep energy well, created by tuning an externally applied magnetic field. The simultaneous electrostatic confinement of electrons and magnetic confinement of ions avoids anomalous transport and facilitates classical containment of both electrons and ions. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions they are fused together by nuclear force, thus releasing fusion energy. Moreover, the fusion fuel plasmas that can be used with the present confinement system and method are not limited to neutronic fuels only, but also advantageously include advanced fuels.
