Distributed harmonic measurement is one of the key characters for power quality evaluation in residential monitoring networks. Synchronization of the electrical sensing node of the network is important in distributed harmonic measurement. The synchronization method needs to be time-efficient, accurate and trustworthy. Pulse-coupled oscillators (PCO) has been imported as the synchronization algorithm...
High quality face image acquisition from huge video data obtained in visual sensor network is of great significance in applications related to face processing, such as face recognition and reconstruction. This paper proposes an optimal face image acquisition method in visual sensor network, which is based on collaborative face frames acquisition and heterogeneous feature fusion-based face quality...
This research attends to provide a simple and effective way to precisely assemble a quartz MEMS accelerometer, which is composed of a double-ended tuning fork (DETF) force transducer, and a base-proof mass structure. Flip chip method is proposed to bond the two sides of DETF in length direction onto the base and proof mass structure via AuSn solder utilizing the self alignment function of reflow process...
