    • A small size apparatus for measuring and recording acceleration comprises an acceleration sensor (11), an AD converter (12) which converts the output signal of the acceleration sensor (11) to a digital signal, a control element (13) which processes the digital signal, a detachable external memory device (11) which stores data of a change in acceleration, a battery (15) for supplying electric power to the sensor (11), the AD converter (12), the control element (13) and the external memory device (14). The small size apparatus is mounted on a moving body to be measured and the entire small size apparatus is drive by the battery. The correct attachment of the external memory device (14) is detected by steps of writing data into a special address, reading the data out thereafter, and comparing the written data and read data, and when the read data coincides with the written data, it is judged that the external memory device is correctly attached.
      In the method for carrying out a zero gravity experiment, the zero gravity experiment system is free floating from the space shuttle or the aircraft.
    • 加速度传感器(11)的测量和记录加速度A小尺寸装置包括至AD转换器(12),该加速度传感器(11)为数字信号的输出信号转换,处理这个数字的控制元件(13) 信号,一个可拆卸的外部存储装置(11),其存储在加速度的变化的数据,用于提供电力至传感器(11),AD转换器(12)的电池(15),所述控制元件(13)和所述 外部存储装置(14)。 小尺寸装置安装在移动体上进行测量和整个小尺寸装置是由电池驱动。 外部存储装置的正确的附件(14)是由写入数据的步骤制作成特殊的地址检测,读取数据之后进行,并且比较写入数据和读取数据,并且当读出的数据与写入的数据一致时,它 判定出没有外部存储器装置是否正确连接。 在用于进行零重力实验的方法中,零重力实验系统是从航天飞机或飞行器自由浮动。
