摘要:
Various aspects of multiple-channel light transmitting systems are disclosed. The system may include a multiple-wave length light source, a demultiplexer; a modulator, and a wavelocker. The wavelocker is configured to drive the light source such that said multiple wavelengths coincide with the ITU grid. The system may also include other elements including a locker or a mode-locking servo, where the servo is configured to adjust the mode locking method frequency to coincide with the spacing of the ITU grid. Further additional elements may include an optical amplifier or an equalizer. The equalizer may include a filter whose transmission function varies with wavelength.

Members including components of windows and doors are formed by a method that includes obtaining a biopolymer and a filler, feeding them into an extruder, controlling at least the temperature of the biopolymer and the filler within the extruder to promote the initiation of nucleation of the biopolymer, extruding the composite through a die of the extruder to form an extruded member and controlling at least the cooling rate of the extruded member after it leaves the die to promote crystallization of the biopolymer. Methods are disclosed for compounding and pelletizing as well as direct extrusion of the composite. In a preferred embodiment, the biopolymer is polylactic acid (PLA) and the filler is wood fiber. In addition, neat PLA formulations are also disclosed. Further, the heat distortion temperature and the hydrolysis resistance of these members are greatly increased through specific processing conditions and the addition of strategic quantities of additives.

A mold assembly includes a mold base plate and a mold. The mold base plate has a bottom plate located in a recess. The mold can be inserted into and removed from the recess and is located on top of the bottom plate. The mold has a first section that is separable from a second section. When the first section and the second section are located adjacent to each other in the recess, a plurality of cavities is formed, each cavity for receiving a quantity of a drug and compound mixture when the mold base plate and mold are at a temperature other than room temperature

Systems and methods for increasing media absorption efficiency using interferometric waveguides in information storage devices are described. One such system for an interferometric waveguide assembly includes a light source, a first waveguide arm and a second waveguide arm, a splitter configured to receive light from the light source and to split the light into the first waveguide arm and the second waveguide arm, and a near field transducer (NFT) configured to receive the light from the first waveguide arm and the second waveguide arm, where the first waveguide arm and the second waveguide arm converge to form a preselected angle at a junction about opposite the splitter, and where the first waveguide arm and the second waveguide arm are configured to induce a preselected phase difference in the light arriving at the NFT.
