**Figure 6.**

*The completed run. The gray trace of the support structure position has been filtered and the green temperature trace has been added.*

**Figure 6** (and many others like it) shows that a real force acts on the device and support structure when the device is excited. And the force continues to act as long as the device is excited. The obvious question is: can the real force responsible for the pendulum deflection in **Figure 6** be attributed to some mundane cause? The leading candidate, Newtonian vibrational artifacts [13], has already been excluded as it cannot produce a steady force and the device and support structure do not
