Abstract:
1. An information equipment, comprising: an acceleration sensor to detect acceleration values for x, y and z axes of the acceleration sensor; a storage device to store the detected acceleration values; an audio input device to obtain audio information; and a process device to compare each of the detected acceleration values with a threshold value, to determine that the information equipment is in a weightless condition when a state in which all of the detected acceleration values are equal to or less than the threshold value continues for a certain time, to determine that the information equipment is not in the weightless condition when at least one of the detected acceleration values is larger than the threshold value, to record a determination result in the storage device, to activate the audio input device when determining that the information equipment is in the weightless condition, to determine whether there has been shock on the basis of the obtained audio information, and to record shock detection information in the storage device when the process device determines that there has been shock.
