In a master oscillator power amplifier, a driver (208) of a diode laser (202) is specially controlled to generate a set of two or more injection laser pulses that are injected into a power amplifier (204) operated in an unsaturated state to generate a set (50) of laser pulses (52) that replicate the temporal power profile of the injection laser pulses to remove a conductive link (22) and / or its overlying passivation layer (44) in a memory or other IC chip. Each set (50) includes at least one specially tailored pulse (52) and / or two or more pulses (50) having different temporal power profiles.

Process and apparatus for separating hydrocarbons from produced water
InactiveUS20110114566A1Improve uniformityMaximize effectivenessFatty/oily/floating substances removal devicesWater contaminantsHigh concentrationTreated water
A process for removing hydrocarbons such as oil from produced water entrains high concentrations of very small gas bubbles within produced water inside a vertically-oriented primary separation tank by means of aerators immersed in the water inside the tank. Oil droplets coat the gas bubbles which form a buoyant oil-rich froth phase overlying a gas-rich liquid phase. The froth phase flows out through a discharge port in a preferably conical upper section of the primary tank, for disposal or recovery of oil as appropriate. Solid contaminants not borne by the froth phase may be intermittently settled out of the liquid phase and removed for treatment or disposal through a discharge port in a preferably conical lower section of the primary tank. Clean processed water is drawn a medial region of the primary tank for re-use as appropriate. In a preferred embodiment, the froth phase passes into a secondary separation tank for further separation of contaminants by means of gravity and / or supplemental aeration.
