Abstract: In a wireless power transfer (WPT) system, a power-transmitting unit has a loop-shaped magnetic core formed by alternately arranging high-permeability (HP) and low-permeability (LP) core sections to give an interleaving pattern. A primary coil wound on the magnetic core provides a magnetic flux traveling therein when excited by an AC power source. A power-receiving unit has a pickup core shaped and dimensioned to overlie one or any LP core section, and to partially overlap HP core sections immediately adjacent to the LP core section that is overlay. The pickup core has a relative permeability higher than that of the aforesaid LP core section, causing at least a part of the magnetic flux to divert from this LP core section to the pickup core. The diverted part of magnetic flux generates electrical power in a secondary pickup coil wound on the pickup core to achieve WPT.

Abstract: A new ultrasonic aided laser joining method (UAL) for bonding dissimilar materials has been developed. The method is capable of eliminating the laser-induced bubbles at the bonding faces and to improve the joint strength over that of the conventional laser-assisted metal and plastic joining method (LAMP). Some experiments on joining titanium to polyethylene terephthalate have been conducted to show the superiority of UAL over LAMP. The results showed that the joint strength, measured in terms of failure load, was significantly increased when ultrasonic vibration was employed during laser joining. For the LAMP joined specimens, fracture normally occurred at the metal-plastic interface, whereas for the UAL joined specimens, fracture normally occurred in the parent plastic part. The improvement in joint strength is mainly due to the elimination of pores in the resolidified plastic.
