On functional requirements of atmospheric particle monitoring system, this paper designs a distributed atmospheric particle monitoring system. The proposed system consists of a data acquisition network, embedded gateways, a database server and remote monitoring terminals. The data acquisition network consists of mobile data acquisition nodes and router nodes distributed in monitoring areas which are...
3-axis accelerometer is a widely adopted device for applications such as fall detection of the elders, kinematic analysis, building/bridge/landslide monitoring, and so on. To retrieve the sensing data in real time, one may use a wireless module to forward those data to a gateway or server. For outdoor applications, Zigbee/IEEE 802.15.4 technology is often the candidate because it is cost effective...
Internet of thing (IoT) is not only a promising research topic but also a blooming industrial trend. One typical application is environmental sensing which is the basis of automation systems applied in home, factory, agriculture, disaster prevention/detection, and so on. To increase the serving area especially for outdoor scenarios, long transmission range is preferred, but this makes a sensor node...
In this paper, we present an improved charge pump circuit for the non-volatile memories in RFID tags. The circuit consists of a single pumping branch without auxiliary capacitors and operates with a simple two-phase clock. The internal high voltages are used to control the gate and bulk terminals of the charge transfer switch. As a result, the threshold voltage loss and the leakage currents are eliminated...
To support inter-layer prediction with arbitrary frame resolution ratio between successive spatial layers, the scalable video coding (SVC) adopts the mechanism of extended spatial scalability (ESS) to achieve it but with noticeable hardware implementation complexity due to the numerous multiplication operations. Therefore, this paper proposes a hardware efficient inter-layer prediction architecture...
In this paper, it demonstrates a CMOS-compatible transducer for creatinine detection. Different with traditional application of ISFET (Ion Selective Field Effect Transistor), it is not for the hydrogen ion detection. To combine the CMOS MEMS platform with MIP (Molecular Imprinting Polymer) micro coating technologies, the developed MlP-gate ISFET could be used for the detecting of creatinine. The experiment...
