    摘要: A photonic-crystal surface-emitting laser (PCSEL) includes a gain medium electromagnetically coupled to a photonic crystal whose energy band structure exhibits a Dirac cone of linear dispersion at the center of the photonic crystal's Brillouin zone. This Dirac cone's vertex is called a Dirac point; because it is at the Brillouin zone center, it is called an accidental Dirac point. Tuning the photonic crystal's band structure (e.g., by changing the photonic crystal's dimensions or refractive index) to exhibit an accidental Dirac point increases the photonic crystal's mode spacing by orders of magnitudes and reduces or eliminates the photonic crystal's distributed in-plane feedback. Thus, the photonic crystal can act as a resonator that supports single-mode output from the PCSEL over a larger area than is possible with conventional PCSELs, which have quadratic band edge dispersion. Because output power generally scales with output area, this increase in output area results in higher possible output powers.

    摘要: A method for synthesizing 4,4-dihalogen-2-(dialkylamino)methylene-3-oxy-alkylbutyrate and its derivatives has acts of: (a) providing N,N-dialkylamino-alkyl-acrylate in a reaction vessel; (b) adding organic alkali, organic solvent and multiple molecular sieves into the reaction vessel; (c) mixing N,N-dialkylamino-alkyl-acrylate, the organic alkali, the organic solvent and the molecular sieves; and (d) adding 2,2-dihalogen-acetyl-chloride into the reaction vessel and allowing a synthetic reaction of 2,2-dihalogen-acetyl-chloride and N,N-dialkylamino-alkyl-acrylate to obtain 4,4-dihalogen-2-(dialkylamino)methylene-3-oxy-alkylbutyrate. The molecular sieves are able to remove water efficiently to prevent materials in the reaction vessel from undergoing side reactions or changing chemical properties. Furthermore, the molecular sieves are able to adsorb chloride to avoid polymerization reactions for improved yield.

    摘要: A system for processing an object specified by an object specifying language such as HTML, JAVA or other languages relying on relative positioning, that require a rendering program utilizing a minimum set of resources, translates the code for use in a target device that has limited processing resources unsuited for storage and execution of the HTML rendering program, JAVA virtual machine, or other rendering engine for the standard. Data concerning such an object is generated by a process that includes first receiving a data set specifying the object according to the object specifying language, translating the first data set into a second data set in an intermediate object language adapted for a second rendering program suitable for rendering by the target device that utilizes actual target display coordinates. The second data set is stored in a machine readable storage device, for later retrieval and execution by the thin client platform.

    摘要: A method for retrieving, decoding, and processing codes in an intermediate language generated from object specifying languages such as HTML and JAVA is disclosed. The codes in the intermediate language are decoded and processed on a minimally featured and minimally powered machine to generate a screen of information with selections thereon for the user. The file corresponding to the chosen selection is retrieved, decoded, processed, and displayed to the user again for selection. Codes in a simple scripting language are also provided to facilitate the processing of commands.
