CONTROL OF FAN SPEED USING ALTITUDE SENSOR |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To enable an electronic system to detect its operation altitude and respond according to it. <P>SOLUTION: The device comprises a fan (100) configured so as to operate at a variable speed, and a converter (114) electrically connected to the fan (100) to control the speed of the fan (100). The converter (114) receives altitude (118) and outputs a fan speed control signal (116) calculated, based on the altitude (118) to the fan (100). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
