A driver circuit for driving loads such as LED, OLED or LASER diode devices includes a switching converter that has a switching element and reactive elements to provide an output switching voltage by sequential switching operations of the switching element. The load is connected to the output ...
The light-emitting diode (LED) type is also used because the sensor has the same features as those of laser displacement sensors with lower prices. However, the LED type is worse in resolution than the laser type. The LVDT has preferable characteristics. The sensor, which is a transformer ...
