Abstract: A wireless power transmission device includes a transmission device and a control device. The control device generates a driving signal to the transmission device in a first soft-start period, so as to drive the transmission device. The control device senses the current of the transmission device to obtain a current message, and determines whether a foreign object exists according the current message. When determining that the foreign object exists, the control device does not generate a carrier signal. When determining that the foreign object does not exist, the control device generates a carrier signal in a transmission period, and the carrier signal is output through the transmission device.

Abstract: A wireless power transmission device includes a transmission device and a control device. The control device generates a driving signal to the transmission device in a first soft-start period, so as to drive the transmission device. The control device measures an energy message generated by the transmission device to generate a measurement result in a measurement period, and calculates a signal parameter according to the measurement result. The control device accordingly generates a carrier signal according to the signal parameter obtained by the measurement period in a second soft-start period. In a transmission period, the carrier signal is transmitted to the wireless power-receiving device through the transmission device. The energy message is generated by the transmission device in response to a distance between the transmission device and the wireless power-receiving device.

A gain optical fiber doped with special ions is connected to the first optical fiber, and a light detector is provided around the gain optical fiber. When the laser with the first spectrum passes through the gain optical fiber, the gain optical fiber absorbs part of the energy level of the laser with the first spectrum, so that the laser with the first spectrum is converted to generate light with a second spectrum based on the frequency conversion phenomenon. The light detector detects the intensity of the light with the second spectrum, so that the power of the laser source can be obtained.
