REMOTE CONTROL AND POWER SYSTEM

A remote device such as a control value ( 4 ) is powered and controlled by optical energy, supplied by an intensity-modulated light source ( 8 ) and optical fiber ( 10 ). After conversion into electrical form, the light is detected at ( 12 ) and applied to a piezoelectric transformer ( 14 ). The out...

Zusammenfassung:	A remote device such as a control value ( 4 ) is powered and controlled by optical energy, supplied by an intensity-modulated light source ( 8 ) and optical fiber ( 10 ). After conversion into electrical form, the light is detected at ( 12 ) and applied to a piezoelectric transformer ( 14 ). The output of the transformer powers and control an actuator ( 16 ) of the control value.
