    摘要: A solid state light source driver circuit, system and method are provided. The driver circuit includes a rectifier circuit, an energy storage element coupled thereto, a current bleeder circuit coupled thereto, and a switch. The rectifier circuit receives AC input and provides unregulated DC voltage. The switch closes to couple some of the unregulated DC voltage to the energy storage element, and opens to transfer energy to drive the light source. A power factor controller circuit provides an output signal to control the switch. The current bleeder circuit provides supply voltage to the power factor controller circuit within a range and maintains a current flow associated with the AC input that exceeds a predetermined threshold. A constant off-time controller circuit provides a switching frequency control signal to the power factor controller circuit. An EMI filter reduces generated EMI noise.

    摘要: Methods for correcting errors in a GFP-T superblock include buffering the 64 bytes of data in an 8×8 byte buffer, buffering the flag byte in a separate buffer, calculating the CRC remainder, and performing single and double bit error correction in three stages. In the first stage, the CRC remainder is compared to a single bit error syndrome table and if an error is located, it is corrected. In the second stage, the CRC remainder is compared to a double bit error syndrome table and if an error is located, it is corrected. The third stage corrects the second error of a double bit error. The flag byte is processed first, followed by the data bytes, eight bytes at a time.

    摘要: A display device, which can be a plasma display panel or a highly loaded fluorescent lamp, comprises a hollow, translucent glass body containing a medium capable of generating at least several wavelengths of UV radiation. A plurality of phosphors is disposed on the inside surface of the glass body and emits visible radiation upon exposure to the UV radiation. The blue BAM phosphor is most subject to degradation upon long-term exposure to at least one UV wavelength that may be available. The blue BAM along with the red YOE and green CAT phosphors are installed adjacent the inside surface of the glass body to form a first layer; and, the red YOE phosphor is disposed on the first layer to form a second layer, the second layer not being subject to long-term UV degradation. In some embodiments, a layer of alumina may be deposited under the first phosphor layer.
