Typically made of spring steel. The types of springs are complex and various, and mainly include spiral springs, volute springs, plate springs, special springs and the like according to the shapes.
Like most other basic mechanisms, metal springs have existed in the bronze age for a long time. Even with metal, wood is used as a structural member for flexible arches and military projectiles. In the time of renaissance, the precision clock makes the precision spring necessary for the first time. Whereas watchmakers' springs are often made by hand, springs are mass produced in steel wire or similar materials. The advanced manufacturing method makes the spring be ubiquitous.

and the voltage conversion equipment is respectively connected with the field power supply mechanism and the commercial power input interface and is used for converting the power supply voltage input by the commercial power input interface into various power supply voltages with different values required by the field power supply mechanism.
In the spring selection system utilizing platen control:
the field power supply mechanism is also respectively connected with the embedded camera, the data mapping equipment and the area analysis mechanism and is used for respectively providing power support for the embedded camera, the data mapping equipment and the area analysis mechanism.
In the spring selection system utilizing platen control, further comprising:
and a data storage card disposed between the area analysis mechanism and the data mapping device, for storing input signals and output signals of the area analysis mechanism and the data mapping device.
In the spring selection system utilizing platen control:
the data memory card is one of an SD memory card, a FLASH memory card, an MMC memory card and a TF memory card;

In addition, FLASH memory chips are nonvolatile memories, and blocks of memory cells called blocks can be erased and reprogrammed. The write operation of any FLASH device can only be performed in empty or erased cells, so in most cases, the erase must be performed before the write operation can be performed. While it is simple for a NAND device to perform an erase operation, NOR requires that all bits in the target block be written to 0 before an erase can be performed. Since erasing NOR devices is performed in blocks of 64-128 KB, the time for performing a write/erase operation is 5s, whereas erasing NAND devices is performed in blocks of 8-32 KB, which requires only 4ms at most to perform the same operation. The difference in block size when performing erasures further increases the performance gap between NOR and NADN, and statistics show that for a given set of write operations (especially when updating small files), more erase operations must be performed in NOR-based cells.
It is to be understood that while the present invention has been described in conjunction with the preferred embodiments thereof, it is not intended to limit the invention to those embodiments. It will be apparent to those skilled in the art from this disclosure that many changes and modifications can be made, or equivalents modified, in the embodiments of the invention without departing from the scope of the invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
