Abstract: A radio-frequency mouse is used for receiving an electromagnetic wave transmitted by an electronic device. The radio-frequency mouse includes a RF transceiver, a sensor, a micro-controller, a battery, and a power management circuit. The RF transceiver receives and converts an electromagnetic wave into a RF power. The sensor outputs an operation signal according to an operating condition of the RF mouse.

The power management circuit receives the RF power, and selectively supplies the RF power or the battery power of the battery to the sensor and the micro-controller according to RF power. Thus, when the RF power is higher than a preset value, the RF mouse is supplied with power, thereby saving the battery power of the RF mouse and improving a battery life of the RF mouse.

Abstract: A wireless charging system and charging method thereof allows a wireless charging stand to wireless charge an electronic device through electromagnetic induction. The wireless charging stand periodically activates to determine if the electronic device enters a predetermined range. Once the electronic device is sufficiently close, a transmission coil of the wireless charging stand transmits electromagnetic waves induced by a reception coil of the electronic device to generate current. The current is intermittently connected to a load by activating and deactivating a switch based on a charge time sequence to correspondingly change current consumption of the transmission coil. The wireless charging stand determines if the time sequence associated with current consumption is identical to a charge identification time sequence.
