Abstract: An automatic balancer comprising: a balance head configured to rotate integrally with a rotating body around a rotation axis of the rotating body, the balance head including a balance correction mechanism configured to correct imbalance of the rotating body, and a case having a cylindrical outer peripheral surface parallel to the rotation axis and configured to house the balance correction mechanism; a stator provided separately from the balance head and having a shape which is along a circumferential direction of the outer peripheral surface with a clearance from the outer peripheral surface; and a rotor part provided at a position where the rotor part faces the stator on the outer peripheral surface, configured to rotate integrally with the balance head, the rotor part having a shape along the circumferential direction of the outer peripheral surface, wherein the stator and the rotor part are configured to perform wireless communication therebetween.

Abstract: A spectroscopy system including first and second lasers. The first laser is triggered to induce a plasma, such as on a surface of a target at a stand-off distance from the target. The second laser stimulates amplified emissions from the plasma detected by one or more spectroscopes. The gain induced by the second laser detects traces of explosives and other substances on surfaces at stand-off distances. The spectroscopy systems use the same telescopic optics to collect emissions from the detection surface and activated at or just before the peak emission intensity useful for detecting element signatures and intensity ratios from the trace elements in the plasma.
