摘要
An apparatus for detecting and recording accelerations experienced by a structure and a method for operating the apparatus are provided. The apparatus includes an accelerometer, processor, and non-volatile computer memory device. The method includes operating the apparatus in a reduced power state, detecting an acceleration having a magnitude that is greater than a first preselected threshold magnitude, switching each of the accelerometer, processor, and non-volatile computer memory device to a fully operational state, storing accelerometer data in a buffer, switching the processor and computer memory device to a reduced power state until the accelerometer signals that further data is available, storing any further accelerometer data in the buffer, and repeating the steps until a predetermined time has elapsed since the accelerometer last detected an acceleration having a magnitude which is greater than a second preselected threshold magnitude.
