Temperature compensation is achieved by a reference generator using sub-threshold techniques. The chip maintains a steady system clock in a temperature range from - 40 to 100℃. Some novel building blocks are developed to save system power consumption,including a zero static current power-on reset circuit and a voltage regulator. The RF/analog front-end circuit is implemented with digital base-band and EEPROM to construct a whole tag chip in 0. 18μm CMOS EEPROM technology without Schottcky diodes. Measured results show that the chip has a minimum supply voltage requirement of 0.75V. At this voltage, the total current consumption of the RF/analog frontend circuit is 4.6μA.展开更多

Connected components labeling is the essential technique for the extraction. A new fast connected components labeling algorithm was presented. The definition of upward concave set was introduced to explain the algorithm. Feasibility and efficiency of the algorithm were verified with experiments. This algorithm performs well in labeling non-upward concave set connected components and applies to landmarks labeling well. Moreover, the proposed algorithm possesses a desirable characteristic that will facilitate the subsequent processing of fluoroscopic images.展开更多

The application of Intemet of things make its and related enterprises in the supply chain synchronization integration in the process, timely access to relevant information, understand the real needs of the market, the effective control of each link of the supply chain inventory quantity and effectively reduce the supply chain inventory and capital takes up between cooperative enterprises. Thus, in effectively improve the efficiency of the original system at the same time also save the cost of the supply chain management. With the combination of the RFID technique, we finalize the implementation of the logistics information and automation, automatic identification and inspection of finished goods inspection, greatly reduce the human capital, simplify the acceptance of goods and reduce the cost of handling times and human factors caused losses.
