A motor controller includes an output voltage modulator that outputs sinusoidally-modulated voltage for driving a motor; a modulation factor specifier allowing specification of a modulation factor greater than 1. A sum of weight-adjusted triage classification levels of all of the current patients is calculated. A preferred version of the tool has specially designed structure for coupling a handle with the gripper and follower structure such that the tool can effectively and efficiently reach and manipulate crossover tubes that are in particularly difficult to reach areas of a gas turbine. A bypass circuit, positioned on the dielectric layer and the first and second contact holes, and a fusion area are then formed.
