Abstract: The tri-axis close-loop feedback controlling module for electromagnetic lens driving device comprises a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Hall element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.

Abstract: A wireless charging device includes a transmitting-end ferrite core and a transmitting-end coil, wherein the transmitting-end ferrite core have a bottom plate and two upright plates for forming a U-shaped structure defining a charging space therein. One or more wireless power receiving apparatus is put in the charging space. The wireless power receiving apparatus includes a receiving-end coil and a receiving-end ferrite plate, wherein the receiving-end ferrite plate is vertical to the two upright plates. When electrical current flows through the transmitting-end coil to generate an electromagnetic field in the charging space, the electromagnetic field via the two upright plates goes through each of the receiving-end ferrite plates to form an electromagnetic loop. Each of the receiving-end coils generates a charging electrical current induced by the electromagnetic field. Therefore, the present invention can achieve wireless charging to more than one wireless power receiving apparatus at the same time.
