Abstract: An internal radio wave transmission system of building includes a base layer and a transmission layer, with a radio wave transmission channel between the two layers. The radio wave transmission system in a building includes a signal transceiver device, a first reflective plate and a second reflective plate. The signal transceiver device is connected with a telecommunication room, and the signal transceiver device emits and receives radio wave signals. The first reflective plate is disposed in the channel and corresponds to positions of the base layer and the signal transceiver device to receive and guide the radio wave signals. The second reflective plate is disposed in the channel and corresponds to a position of the transmission layer to receive and guide the radio wave signals to terminal equipment located in the transmission layer. The invention ensures the effective transmission of the radio wave signals inside the building.

Abstract: Example methods and apparatus for managing a network device are described. One example method includes obtaining a static dataset and generating a knowledge corpus based on the static dataset, where the knowledge corpus includes information for managing a network device. The static dataset indicates how to manage the network device, and the static dataset includes data that is generated independent of a device interaction process.

Abstract: The present invention discloses an error correction method for an FPP system. Implementation steps are as follows: first, collecting deformed fringes affected by an object using a camera; then, calculating the fringe modulation I? by using the collected images, and normalizing the modulation; setting a segmentation threshold T, and for all pixels of which modulation I?<T, dividing them into several categories and pixels within each category having close I? values; for all pixels in each category, acquiring multiple groups of N intensity values, and averaging these groups of intensity values to obtain a set of averaged intensity value curves; and finally, replacing the corresponding N intensity values of all the pixels in the category with the set of averaged intensity values, to complete image correction.

Abstract: A method for preparing sucralose with high yield, comprising the following preparation steps: First, negative effects of other impurities on reaction are reduced by first preparing a pure Vilsmeier chlorinating reagent. Second, side reactions are prevented by adding composite catalyst to increase selectivity of chlorination reaction. Third, by extracting less polar impurities using less polar solvent when sucralose-6-ester is undergoing deesterification, products are qualified at the very first time so that refining steps are avoided. Accordingly, product loss is reduced and product yield is increased. By using the present invention to prepare sucralose, product yield could be increased to more than 40%.
