A fuel pump controller includes a detecting device for detecting environmental vibrational energy and converting the environmental vibrational energy into an electrical signal. For example, a method of dicing a semiconductor wafer having a plurality of integrated circuits on a front side thereof and metallization on a backside thereof involves patterning the metallization on the backside with a first laser scribing process to provide a first plurality of laser scribe lines on the backside. The invention includes an ultra-compact imaging system based on microlenslet arrays and demonstrates that such a system can achieve an object-to-image distance as low as approximately 1.
