| 摘要 |
The device uses an acceleration sensor(5) effective in the forwards motion direction, coupled at its output to an evaluation and calculation stage(61,..64), providing a comparison value for testing the signals provided by a displacement or velocity detector(3), used for documenting the forwards movement. The evaluation and calculation stage eliminates all except the forwards movement signal component from the acceleration sensor signal, which is provided for at least 2 short successive phases of the forwards movement, with comparative evaluation for each phase. |
