Abstract:
A variable output electrical device including:a source of electrical power;a magnet means for creating a magnetic field, said magnetic field including a magnetic flux;a sensor means comprising a sensor element for emitting an electrical sensor output signal controlled by a density of said magnetic flux intersecting said sensor element;an output means comprising an output element for emitting a perceivable output signal controlled by said electrical sensor output signal;a circuit means comprising said source of electrical power, said sensor means, said output means and a switch for selectively connecting said source of electrical power to said sensor means and said output means for said source of electrical power supplying an electrical power to said sensor means and said output means;a support means for disposing said sensor element relative to said magnet means to effect said magnetic flux intersecting said sensor element; andan adjustment means for a movement of a movable element to vary said density of said magnetic flux intersecting said sensor element to vary said perceivable output signal and to vary said electrical power supplied to said output means.
