Abstract: A battery adapted to a wireless charging system which comprises a coil, a PCB, a core, a shield and a case. The coil is configured to induce the magnetic power transmitted from the transmitter of the wireless charging system to generate inductive current. The PCB is electrically connected the coil to transform the inductive current of the coil into electrical power. The core is electrically connected the PCB to store the electrical power. The shield is sandwiched between the coil and the core to protect the core from magnetic power of the transmitter and enhance inductance of the coil; and the case is configured to enclose the coil, the PCB, the core, and the shield therein. The invention also discloses a wireless charging system with such a battery, a electronic device with wireless charging function.

Abstract: An intelligent locking device comprises a microprocessor, a locking element and a control button electrically connected to the microprocessor respectively. The locking element locks a removable HDD to a computer. The control button generates trigger signals in response to manual push thereon. When receiving the trigger signal, the microprocessor detects whether there is data transferring between the removable HDD and the computer, if there is data transferring, the microprocessor terminates data transferring and then sends a driving signal to the locking element; if not, the microprocessor directly sends a driving signal to the locking element. When receiving the driving signal, the locking element releases the lock between the removable HDD and the computer to permit the removable HDD to be safely ejected. Meanwhile, a removable HDD receiving system with the locking device and a method for preventing the removable HDD from being wrongly ejected from the receiving system are disclosed.
