Some handheld electronic devices that require a directional pattern are equipped with directional printed antennas, along with a large ground plane. However, such an arrangement is cumbersome and expensive for small devices. The drawback inspires the invention of this novel unidirectional antenna fo.....

Flash memories have attracted considerable attention as promising next-generation nonvolatile memories owing to their higher chip density, multi-bit per cell storage properties, and compatibility with the current complementary metal-oxide-semiconductor process. To facilitate information storage, nan.....

We are exploring applications of ZigBee technology to a range of medical applications. The medical sensors in the system automatically send the measured data (e.g. blood pressure, body temperature, blood glucose level and heart rate) to the ZigBee coordinator. The ZigBee coordinator collects the mea.....
