We noticed that central processing units (CPUs) accounted for a large volume of power consumption and that CPU functions were usually excessive for sensor node control. Direct memory access (DMA) was substituted for the CPU when iterative routine processing was operated in this research, and the CPU was made to fall asleep while the DMA responsibly controlled tasks. The experimental results revealed that DMA-driven control reduced power consumption to 37% compared with CPU-driven control in 28 MHz operation. We concurrently discovered defects in the existing micro-controller units (MCUs) for further reducing power. We also propose an improved hardware architecture.","PeriodicalId":293397,"journal":{"name":"2015 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116462338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sensor data were collected on two pre-stressed box beam bridges (PSBB) with eight wireless sensor nodes. The wireless sensor was able to collect one hundred Accelerometer data samples per second without losing any wireless sensor data. Application software was developed to transform the sample data into frequency domain. Sensor data from all eight wireless sensor nodes have shown the similar peak frequencies with multiple trial runs on the same bridge. The peak frequency component was unique to each highway bridge. The signal to noise ratio in frequency domain is greater than seven to one. By comparing the actual wireless sensor data with the predictions from a finite element bridge model, a hypothesis of evaluating the structural health of the bridge was presented.","PeriodicalId":293397,"journal":{"name":"2015 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132327251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

VCSEL typically show large direct modulation bandwidths 10 GBit/s due to their short cavity related short photon lifetime.

A MIMO system where paths take turns to act as transmitter with the remaining paths serving as receivers is used to enable the position estimation. For proof of concept, a local position measurement system demonstrator comprising a commercial off-the-shelf RFID reader, conventional passive EPCglobal Class-1 Gen-2 UHF RFID tags, several transceivers, baseband hardware, and signal processing was built.

Zwick","doi":"10.1109/WISNET.2015.7127413","DOIUrl":"https://doi.org/10.1109/WISNET.2015.7127413","url":null,"abstract":"In production and automation engineering the need for highest precision distance sensors is ubiquitous especially in the field of micro-machining processes where an extremely accurate positioning is indispensable. Although the work pieces become smaller and smaller many machine tools stay big and heavy. The reason for this is that a high precision is necessary and in this way the machine tools must be robust and stiff in their rails to prevent positioning errors due to tilts or twists. By using accurate sensors integrated in the rails of the machine tool the positioning error increases since the distance between the measurement of the position and the machine tool itself is relatively large. For this reason it might be advantageous to measure as close as possible at the tool center point (TCP) which could also allow for a reduction in machine sizes. A radar system might be a promising approach for this measurement due to the progressive development in radar technology along with new and fast algorithms. In this paper an frequency modulated continuous wave (FMCW) radar system is presented working around a center frequency of 80 GHz with a modulation bandwidth of 10 GHz. In combination with an innovative signal processing concept that uses frequency and phase evaluation a sub-micrometer accuracy can be achieved over distances up to several meters. The high accuracy of ±0.5 μm is demonstrated in a novel measurement setup for a kinematic using compliant mechanisms with flexure hinges.","PeriodicalId":293397,"journal":{"name":"2015 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet)","volume":"321 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123506831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
