| The physical activity tests were validated using electronic accelerometers to measure levels of activity minute by minute. |
| The delicate accelerometers and inertial guidance components did all the piloting until the second stage kicked us loose. |
| One unit malfunctioned due to failure of one of the three internal accelerometers during a measurement period at home, and the subject was retested with another device. |
| In this case, the accelerometers could damp or increase the vibrations through their contact with the vehicle. |
| In addition, NASA's second redesigned tank has been outfitted with temperature sensors and accelerometers, used to measure vibration. |
| For more rigorous demonstration of the forces involved, Dial also used two accelerometers to measure the acceleration in the forward and vertical directions. |
