Methods, apparatus, and system to compress a data file to form a compressed data file. The data file may be used to configure control of hardware, such as peripheral hardware. The compressed data file may be stored locally or transmitted to another computer device. The compressed data file may be stored in a flash memory. The compressed data file may require less space in flash memory components, relative to flash memory suitable to hold the (original, pre-compressed) data file. Compression and/or decompression may be performed by, for example, a flash memory controller. The compressed data file may be decompressed dynamically, on an as-needed basis, to provide code for execution by a processor and/or to configure a computer device to use hardware or other components. Other software and hardware components do not need to be aware that the data file is compressed in the flash memory.

Flash data compression decompression method and apparatus

The present invention provides a governor assembly and an elevator, wherein the governor assembly includes: a support; a first axle rotatably supported by the support; a main pulley rotatably mounted on the first axle relative to the first axle; a first guide pulley near the main pulley; a first safety device actuated by the rotation of the first axle; and a centrifugal tripping mechanism which enables, when a rotating speed of the main pulley exceeds a preset value, the main pulley and the first axle to be coupled and rotate together. The governor assembly according to the present invention is of a compact structure and is applicable to a small mounting space.

Governor assembly and elevator

The present invention relates to the technical field of an elevator, and provides a governor of an elevator. The governor of the present invention is provided with a reset push part which is disposed on a ratchet wheel and is used for resetting the governor from a second state to a first state, wherein the reset push part and a pawl of the governor are set in such a manner that when a rope sheave rotates in a direction, the reset push part pushes the pawl to reset the pawl to a position corresponding to the first state.

The present invention relates to a method for preparing 6-substituted amino-3-cyanoquinoline compounds (compound A for short) and the intermediates thereof, more particularly, to a compound of the following formula (I), the preparation method thereof, the intermediates thereof and use thereof for preparing the compound A. The compound of the formula (I) is cyclized in the presence of an alkali to give a compound of formula A, wherein W is OH; or the compound of the formula (I) is cyclized in the presence of an alkali, and then chlorinated to give a compound of the formula A, wherein W is Cl. Compared with the known methods in the literature, the method for preparing the compound A from the compound of formula (I) according to the present invention can avoid using high-temperature condition and high boiling point solvents, and is safe and environment-friendly, mild in reaction condition, easy in operation with a high yield and high product purity.
