Abstract: A wireless power transfer and rapid charging system with maximum power tracking and a method for the same are revealed. The system includes a transmitter device and a receiver device. First the transmitter device performs maximum power tracking and outputs a fixed resonant frequency. Now the receiver device charges a battery. A voltage detection circuit of the receiver device is detecting charging state of the battery. A high-frequency receiving circuit of the transmitter device checks whether a high-frequency transmission circuit transmits a fully-charged signal. When the high-frequency receiving circuit of the transmitter device receives the fully-charged signal that represents the battery is fully charged, the transmitter device shuts down the power and enters standby mode. Thereby wireless charging can be carried out in different environments. The greater transfer distances, lower output impedance, and higher wireless transmission efficiency can be achieved. The speed of wireless charging is also increased.

Abstract: An apparatus for reducing laser speckle cooperates with a laser light source and comprises a light guide tube and a vibration element coupled on the light guide tube. The light guide tube includes an input member corresponding to the laser light source, an output member far away from the laser light source, and a chamber allowing a laser beam which is emitted by the laser light source to perform total reflection inside. The vibration element is arranged at a region between the input member and the output member to drive the light guide tube to vibrate reciprocally along a direction not parallel to the axis of the light guide tube. The vibration element controls the light guide tube to perform swift, reciprocal and high-frequency vibration to destroy coherence of the laser beam. Thus the laser beam can be output uniformly to avoid laser speckles caused by light interference.
