The proposed system is designed using a 32-bit ARM-7 embedded microprocessor system to carry on power data processing and relay control through GPRS mobile communication. In order to provide a cost-effective, wireless, always-connected, two-way data link function capability, the proposed system establishes a remoter monitor and control center to manage power equipment operation data, power parameters and outage signals. To activate the data flow, GPRS is used to handle real time message in two ways, from equipments to the control server, and from operator to the equipments. In this paper, the proposed system is successfully built up, and a full function of real time remote operation is tested with data collection, especially at a system outage. This paper verifies the proposed system is useful and effective to power equipment monitor and control in a real time and mobile condition","PeriodicalId":214056,"journal":{"name":"2005 Sensors for Industry Conference","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114384331","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}

However, once a warning signal is being generated, most operators are not knowledgeable to take any action on it. Data acquisition has to rely on maintenance engineer using special tools. Based on such a practical demand, this paper presents a new vehicle on-line diagnosis and real time early warning system to acquire OBD signals and transmit to a Server of Maintenance Center via GPRS mobile communication for immediate actions. In this paper, hardware and software in both design and implementation are discussed with preliminary tests.

Even modern compact portable systems based on solid-state lasers. Light emitting diodes (LEDs), and photodiodes (PD) use traditional optic elements, such as lenses and glass or interference optical filters to make the spectral bands of both light sources and photodetectors selective in order to characterize specific parameters. In this work we demonstrated integration of multi-spectral III nitride based wavelength-selective LED and PD chips on a single miniature substrate, which will allow for avoiding optical filters and waveguides. The multifunctional capabilities of such sensor are provided by the multi-band LED emission and detection in a wide wavelength range from near UV to near IR.

The device comprises a silica microstructure suspended at a small distance above a glass substrate. A sputtered NiO thin film is used as the formaldehyde sensing layer. The gas sensor incorporates Pt heating resistors integrated with a micro hotplate to provide a heating function and utilizes Au interdigitated electrodes. When formaldehyde is present in the atmosphere, it is adsorbed by the sensing layer and causes a change in the electrical conductivity of the NiO film. Therefore, the measured resistance between the interdigitated electrodes changes correspondingly. The application of a voltage to the Pt heaters causes the temperature of the micro hotplate to increase, which in turn enhances the sensitivity of the sensor. The nanometer scale grain size of the sputtered oxide thin film is conducive to improving the sensitivity of the gas sensor. The experimental results indicate that the developed device has a sensitivity of 10 ohm ppm-1 at 300degC and a detection capability of less than 1.0ppm","PeriodicalId":214056,"journal":{"name":"2005 Sensors for Industry Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128731567","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}

Some radio network designs, such as ZigBee, presume that radio connectivity is reasonably consistent over time. Others take the opposite approach of presuming that links are entirely unreliable, and build large degrees of physical redundancy into the network in the hope that a collection of redundant but unreliable individual links will result in a reliable overall system. Surprisingly little work has been done in the middle ground, endeavoring to understand the root cause of link failure in real-world factory environments and applying this knowledge in the design of protocols that adoptively detect and use workable radio channels. In collaboration under a Department of Energy grant for the Industries of the Future, General Electric and Sensicast Systems have studied theoretical and actual performance of 2.4 GHz IEEE 802.15.4 radio transceivers on the lab bench and on the factory floor, with particular attention to jamming from 802.11 and multipath fading. Temporal and frequency variations in link quality are explored.

The ultrasonic transit time sensor described here uses only a one-way ultrasonic pulse. The transit time, typically 0.5 to 50 ms, is proportional to the distance between the ultrasonic transmitter and receiver transducers. There are three advantages: (1) the ultrasonic signal loss is much less, (2) the location of the transducers is well defined, and (3) the phase and pulse shapes are controlled and reproducible. An optical pulse is used to synchronize the transmitter and receiver.
