Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
A multi-point temperature control heating control system was designed using the SST89E564RC single-chip microcomputer and a new temperature measuring device. The heating system can be controlled in...[Details]
