Design of a Rotary Ring APP Information Capturer for Sightseeing PlacemSpecialized Tourism Services for Sun-Moon Lake

The APP （Application） store at the Android market is very popular and attractive for most of current smart phone users. A rotary ring type of APP named as Loving SML （Loving Sun-Moon Lake--＂爱上日月谭＂） is an instant information capturer to capture the instant traffic tourism information （info） services and serve as an interactive device for user to know the instant traffic information of SML area where you may want to go. The tourism service is specialized on i3 travel, which is identified as innovation, intelligent, and interesting for all of the visitors coming from all over the world. The captured instant information is provided by the sightseeing cloud from SML-NSA （National Scenic Area） with the integration of infrastructure of VD （vehicle detector）, CMS or VMS （changeable （or variable） message sign）, CCTV （closed circuit television）, AVI （automatic vehicle identification）. The technique of AR （augmented reality） is also used to identify how many sparkling places in front of you that you may visit. One can easily know the road performance ahead from you before you plan a trip.

基于NFC技术的标签模式设计

设计上主要利用业界第一块标准的NFC功能芯片(PN544)来实现NFC技术中的标签模式。该标签模式是模拟ISO14443标准定义的Type A卡。与如今大部分的实现模式不一样的是:通过采用NXP公司的主控芯片(LPC1114)来直接配置PN544。该实现方法是根据NFC协议开发相应的驱动程序。使用SCM公司的读卡器(SDI011G)来验证标签模式的配置是否成功。如果是成功的配置,那么读卡器可以探测到PN544和LPC1114构成的设备。

Effects of Co2O3 concentration on high Q-factor NiCuZn ferrites for 13.56 MHz radio identification communication

Co₂O₃-doped NiCuZn ferrites with a high (group A) or low (group B) permeability were prepared using the conventional ceramic method to obtain high Q-factor NiCuZn ferrites for a 13.56 MHz near-field-communication (NFC) system. The XRD patterns of samples from both groups exhibited single spinel phase. Permeability monotonously decreased with increasing Co₂O₃ content, whereas sintering density and saturation magnetic flux density (Bs) slightly changed with Co₂O₃ content. The permeability of 0.45 wt% Co₂O₃-doped ferrite (A_0.45) was similar to that of 0.10 wt% Co₂O₃-doped ferrite (B_0.10). However, the former sample presented a considerably higher Q-factor than the latter sample. The former sample also presented enhanced stability variation of Q-factor with frequency, which indicated an improved electromagnetic shielding function for the NFC system. The mechanisms involved were also elucidated.
