<p><P>PROBLEM TO BE SOLVED: To provide a system and method which takes advantage of optical power supply and provides a cost efficiency. <P>SOLUTION: Optical power supply uses light to run remote, isolated circuits without the need for metallic wires. An optical power system 100 includes a single photovoltaic component 110 that supplies a first voltage in response to impingement of light thereon. A voltage booster 120 receives the first voltage from the photovoltaic component 110 and outputs, to a V<SB>OUT</SB>terminal, signals of a second voltage that is greater than the first voltage. The optical power supply system 100 may be configured by integrally including a sensor to which power is supplied by the second voltage from a voltage booster 120. The photovoltaic component 110 may be an inexpensive light-emitting diode. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
