  • Patent number: 9918369
    Abstract: Disclosed is an LED backlight driving circuit and method for detecting failure thereof. A driving chip of the circuit, on the one hand, is electrically connected to a control end of a booster unit so as to transmit a gate control signal to the booster unit, for regulating a driving voltage supplied by a power supply unit to an LED light strip through the booster unit, and on the other, is electrically connected between an output end of a detection unit and a negative end of the LED light strip, forming a current path of the LED light strip. When the detection unit outputs a variable testing voltage, the driving chip controls a current flowing through the LED light strip so that the current changes with the testing voltage, and judges whether to cut off its electrical connection to the LED light strip based on a comparison of a voltage on the negative end of the LED light strip and a predetermined threshold voltage.

  • Patent number: 9890713
    Abstract: A silencer apparatus for a gas turbine inlet system ducting is disclosed. The inlet ducting contains a main silencer and a pre-silencer, and Inlet Bleed Heat (“IBH”) located between the silencers. The pre-silencer decreases the noise level from the turbine compressor and makes the air flow/temperature profiles more uniform. The main silencer reduces noise from the IBH and the remaining noise from the compressor to an appropriate level. The main silencer is comprised of a first plurality of sound-absorbing splitters disposed along the gas flow direction in the gas turbine inlet ducting. The pre-silencer is comprised of a second plurality of sound-absorbing splitters disposed along the gas flow direction in the gas turbine inlet ducting, but staggered with respect to the first plurality of splitters to thereby block a direct line of travel for noise acoustical waves from the compressor travelling opposite the gas flow direction in the inlet ducting.
