  • Patent number: 8847509
    Abstract: A charging diode 6 is connected to the capacitor 3 and the anode of a first LED 11, and limits the direction of the charging current. A discharging diode 7 is connected to the capacitor 3 and the cathode of the first LED 11, and limits the direction of the discharging current. A charging path CP is provided which includes the capacitor 3, the charging diode 6, and the charger 5. The capacitor 3 is charged through the charging path CP. A discharging path DP is provided which includes the capacitor 3, the discharging diode 7 and a discharger 4. The capacitor 3 is discharged through the discharging path DP. A transient path TP is provided which does not include the capacitor 3 but includes the first LED 11, the charger 5 and the discharger 4.

  • Patent number: 8344625
    Abstract: A plasma lamp apparatus that includes an improved bulb support assembly to increase the lumens per watt output of the apparatus. The bulb support assembly includes a support structure that forms a cavity for receiving the bulb. The bulb is supported within the cavity though a protrusion that extends out from the support structure in a curved manner. By created a curved protrusion, the electric field within the resonating structure of the lamp apparatus is lowered. Lowering the electric field leads to lower resonating frequencies of the resonating structure. In lowering the resonating frequency, the resonating structure is driven to resonate at lower power levels, thereby increasing the lumens per watt output of the lamp apparatus.

  • Publication number: 20080191635
    Abstract: A multi-lamp backlight module integrates the capacitors into a circuit board, and the circuit board is located on the liquid crystal display panel. The backlight module includes a driving unit having a driving transformer, and a backlight unit. The driving transformer provides two output terminals. The backlight unit includes a circuit board and at least one CCFL. The circuit board is located at the liquid crystal display panel. The circuit board has at least one capacitor, and first ends of the capacitors are commonly connected with one output terminal of the driving transformer. The CCFLs are located on a back side of the liquid crystal display panel. First ends of the CCFLs are commonly connected with another output terminal of the driving transformer, and second ends of the CCFLs are respectively connected with the second ends of the capacitors.

  • Patent number: 5636324
    Abstract: A stereo audio encoding method for encoding left and right original signals to a left and right reproduced signals for suppressing a loss of quality in the reproduced audio signal. The correlation between the right and left channel signals is determined, and the phase of each signal is compared. If the two signals have the same phase, a modified scale factor is calculated based on a power equalization method, but if the two signals are in opposite phase, another modified scale factor is calculated based on an error minimization method. The modified scale factors are used for calculating the reproduced signals.

  • Patent number: 4131826
    Abstract: An RLC triggering circuit employs an inductance coupled to the trigger electrode of a triggered vacuum gap device. A capacitance and a switch are coupled in series with the inductance. A diode in parallel with the series-coupled capacitance and switch serves to provide a long, unidirectional current pulse to prevent the triggered vacuum gap from chopping current and generating dangerous surge voltages.
