Can be reconstructed this and screw curve.But be enough for the single value of this each data point.This is as each data point
(Sample_n) value (M_n) calculating have again one be similarly less than torque-time-to data bulk size size.
The size of this packet also may be, for example, 4 bytes.Therefore-except for time started, sampling rate value preset to required for number
Data bulk outer-minimizing of the data bulk of every bit for screwing curve is possible.In the example illustrated can be rotation
The data bulk of the every bit of stubborn curve for example halves.Thus produce, (for time started, sampling rate value preset to number
In the case of the identical data bulk of the value of each each single calculating screwing curve point (M_n)) go out from such as 4 bytes
Send out one four values, (4 × 2 × 4=32 byte) is made up of screw curve in the case of have been able to realize data bulk
Minimizing (to 3 × 4+4 × 4=28 byte).
