Detailed Description
Embodiments of the present invention of a parachute jumping mechanism pop-up platform and method based on signal detection will be described in detail below.
A Hot Air Balloon (Hot Air Balloon) is an aircraft that is lighter than Air, with an atmospheric Balloon in the upper half and a gondola in the lower half. The interior of the balloon heats the air, which has a lower density relative to the cold air outside, acting as a buoyancy to displace the whole; the gondola can carry passengers and a heat source (mostly open fire). Modern sport balloons are typically made of nylon fabric with openings made of fire resistant material.
Can be used for aeronautics and sports, photography, travel and the like. The first manned balloon was made of Montgolfier brother, Paris, 11.21.1783
de Rozier and
laurent d' Arlandes two-person start. The first hot air balloon flying in america was launched from a walnut prison in philadelphia by the french airline Jean pierre blanchard in 1793, 1-9. The current types are AA, AX, AM and AS.
At present, in case the fire balloon height transfinites and has fallen the control of the safe rope body in bottom, then personnel on the fire balloon will be absorbed in the high altitude crisis of falling, at this moment, adopt near helicopter to rescue and be the emergency measure of using always, however this kind of emergency measure need consume certain rescue time and economic cost is higher, keeps helicopter to hover near the fire balloon also not too realistic simultaneously.

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.
