In this paper, a novel portable hard-disk encryption/decryption system with a MEMS coded lock is presented, which can authenticate the user and provide the key for the AES encryption/decryption module. The portable hard-disk encryption/decryption system is composed of the authentication module, the USB portable hard-disk interface card, the ATA protocol(More)
It is presented in this paper an active magnetic levitation system used for the nanogram detection in biomedical domain. The design, simulation and levitation experiment are presented in detail. The device is composed of three parts: planar coil electro magnetic (EM) as lower stator, permanent magnetic (PM) as rotor and capacitance plate as lower stator.(More)
Cell equalization is a critical technology to enlarge battery pack capacity and prolong battery cycle life. A cell equalizer based on an isolated bidirectional flyback converter is introduced in this paper. Energy can be transferred from one cell to the pack or from the pack to some cell through a double winding transformer. An n-MOSFET and a milliohm(More)
