A system and method for using reluctance torque or a combination of both reluctance and reaction torque components of an attached synchronous machine to accelerate a prime mover, such as a gas turbine engine, within a desired start time. The first power control circuit keeps the amplitude of a modulated input signal constant, and the demodulation circuits applying a demodulation processing to the input signal. Real objects used in an application that uses a mixed reality space may be used. This scanning mirror and an image projection device using this scanning mirror can display an image at sufficient brightness safely. The tower utilizes a carrier web onto which the fluoropolymer layer and second polymeric layer are deposited from respective casting films. The first substrate is provided with a second substrate rotatably engaging the magnetic medium.
