    摘要: Disclosed is a central cache that is updated without the overhead of locking. Updates are “atomic” in that they cannot be interrupted part way through. Applications are always free to read data in the cache, accessing the data through a reference table. Applications do not directly update the cache, instead, they send update requests to a service routine. To update the cache, the service routine proceeds in two phases. In the first phase, the service routine prepares the new data and adds them to the cache, without updating the reference table. During the first phase, an application accessing the cache cannot “see” the new data because the reference table has not yet been updated. After the first phase is complete, the service routine performs the second phase of the update process: atomically updating the reference table. The two-phase update process leaves the cache, at all times, in a consistent state.

    摘要: Various technologies and techniques are disclosed that improve text rendering contrast. The shape of one or more characters is converted from an original format, such as a vector format received from a font, to an overscaled bitmap format. The width of the shape of the character is adjusted based on a text contrast setting. For example, the width of the shape can be adjusted by extending a right or other edge of the shape by the number of pixels corresponding to the numerical value of the text contrast setting. The shape is made wider or thinner based on the text contrast setting. A filtering procedure is used to determine density values for how the shape corresponds to a set of screen pixels. The density values are blended with color values related to the display device to form a modified shape ready for output. The modified shape is then displayed.

    摘要: Disclosed is a method for producing deposition particles or intermediate particles, characterized in that the method comprises: forming a solution comprising a solvent and one or more deposit sources, aerosolizing the formed solution to produce an aerosol of precursor particles comprising the deposit source, conditioning the precursor particles to produce deposition particles or intermediate particles from the deposit source and collecting said particles. The particles may be collected as a deposit or precursor deposit on a substrate. The particles may include a matrix material and a dopant. The conditioning may be quenched to produce a desired substructure. The matrix material may be essentially optically clear. The substrate may comprise an optical fiber or an optical fiber preform or mandrel.
