This paper implements a GPRS-based embedded system for load management system in real time remote operation to power equipments in general applications. 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

On-board diagnostics (OBD) system is developed to detect vehicle system error and malfunction for health diagnosis, OBD generates warning signals to vehicle operators as well as the maintenance engineers. 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. The test functions of the proposed system fulfil the rising requirements for modern vehicle system

High-sensitivity (parts-per-billion) optical sensors based on fluorescence, absorption, and scattering can be employed not only for detection of various analytes, but also to determine the concentration, size, temperature, pressure, and flow of the medium. 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. Such capabilities will be further improved in the proposed sensors by using a surface enhancement effect (SEE) based on employment of by metal nanostructures in the analyte vicinity
基于荧光、吸收和散射的高灵敏度(十亿分之一)光学传感器不仅可用于检测各种分析物,还可用于确定介质的浓度、大小、温度、压力和流量。即使是基于固态激光器的现代小型便携式系统。发光二极管(led)和光电二极管(PD)使用传统的光学元件,如透镜和玻璃或干涉滤光片,使光源和光电探测器的光谱带具有选择性,以便表征特定参数。在这项工作中,我们展示了基于多光谱III氮化物的波长选择LED和PD芯片在单个微型衬底上的集成,这将允许避免光学滤波器和波导。这种传感器的多功能能力是通过在近紫外到近红外的宽波长范围内的多波段LED发射和检测提供的。这种能力将通过在分析物附近使用金属纳米结构的表面增强效应(SEE)进一步提高

A significant limitation to the applications of fiber Bragg gratings (FBG) sensors is the sensitivity of the Bragg wavelength to both temperature and strain, complicating the independent measurement of these parameters. In this letter, we explore a new method to discriminate strain and temperature in FBG sensors, which utilizes the additional wavelength dependent phase introduced by Fiber Bragg grating written on sensing arm of Mach Zehnder interferometer (MZI). The intensity variations of the MZI output at the wavelength outside the Bragg resonance provide an additional parameter along with the Bragg wavelength shift observed at the input end for simultaneous measurement of strain and temperature
光纤Bragg光栅(FBG)传感器应用的一个重要限制是Bragg波长对温度和应变的敏感性,使这些参数的独立测量复杂化。本文探索了一种新的方法,利用写在马赫-曾达干涉仪(MZI)传感臂上的光纤布拉格光栅引入的附加波长相关相位,在FBG传感器中识别应变和温度。MZI输出在布拉格共振外波长处的强度变化与在输入端观察到的布拉格波长位移一起提供了一个额外的参数,用于同时测量应变和温度

This paper presents a novel microfabricated formaldehyde gas sensor with enhanced sensitivity and detection resolution capabilities. 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
本文提出了一种新型的微加工甲醛气体传感器,具有更高的灵敏度和检测分辨率。该装置包括悬浮在玻璃基板上方小距离处的二氧化硅微结构。采用溅射NiO薄膜作为甲醛感应层。该气体传感器将铂加热电阻与微热板集成在一起,以提供加热功能,并利用Au交叉电极。当甲醛存在于大气中时,它被感应层吸附,并引起NiO薄膜电导率的变化。因此,交叉电极之间的测量电阻也会相应变化。对铂加热器施加电压会使微热板的温度升高,从而提高传感器的灵敏度。溅射氧化薄膜的纳米级晶粒尺寸有利于提高气体传感器的灵敏度。实验结果表明,该装置在300℃时的灵敏度为10欧姆ppm-1,检测能力小于1.0ppm

Wireless mesh sensor networks are being deployed today in various monitoring and control applications. 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 implications for network reliability and protocol design are discussed
无线网状传感器网络目前被部署在各种监测和控制应用中。一些无线网络设计,如ZigBee,假定无线电连接随着时间的推移是相当一致的。另一些人则采取相反的方法,假设链路完全不可靠,并在网络中建立很大程度的物理冗余,希望冗余但不可靠的单个链路的集合将导致可靠的整体系统。令人惊讶的是,在中间地带几乎没有做什么工作,努力了解真实工厂环境中链路故障的根本原因,并将这些知识应用于协议的设计中,采用自适应检测和使用可行的无线电信道。通用电气公司和Sensicast系统公司在能源部未来工业资助下合作,在实验室工作台上和工厂车间研究了2.4 GHz IEEE 802.15.4无线电收发器的理论和实际性能,特别关注802.11和多径衰落的干扰。探讨了链路质量的时间和频率变化。讨论了对网络可靠性和协议设计的影响

Guided wave optics in combination with micro-machining technology offer immense potential for sensor applications. In this paper we analyse an guided wave optics based MEMS pressure sensor consisting of a Mach-Zehnder interferometer whose sensing arm is over the edge of a bulk micromachined silicon diaphragm. We compare this sensor utilising the elasto-optic effect with the conventional piezo-resistive and capacitive micromachined pressure sensors in terms of their sensitivities. This MOEM pressure sensor is found to be superior to the conventional ones. This sensor can be used for blood pressure monitoring, precision instrumentation, aerospace propulsion application with suitable design parameters

An Ultrasonic/Optical Pulse Sensor for Precise Distance Measurements 用于精确距离测量的超声/光脉冲传感器
Pub Date : 2005-02-01 DOI: 10.1109/SICON.2005.257865
D. Wobschall, M. Zeng, B. Srinivasaraghavan
The combined ultrasonic transit time and optical pulse method described here is an improvement over the standard ultrasonic echo by providing a lower signal loss and more precise location of sensor reference points, specifically the transmitting and receiving transducers. 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. In this version the optical pulse is sent from the ultrasonic receiver unit, initiated by its microcontroller, to the ultrasonic transmitter unit

The design and development of a controller for a near infrared glucose sensor is described. The sensing technology involves the sampling of interstitial fluid in a micro fabricated chamber and measurement of the absorbance of the fluid in a non-destructive and reagent free manner. The glucose levels are estimated based on the absorbance data. This new technology relies on the unique optical characteristics of glucose in a near infrared spectrum and will be used as the sensing technology in a feedback controlled insulin delivery system for the in situ treatment of diabetes. The sensor element will be implanted in the subcutaneous tissues of the human body and the controller will enable the operation of the sensor for months with minimal user intervention. First generation prototype of the controller has been developed and implemented. Currently, thorough testing of the first generation prototype system is in progress and work on a second generation prototype based on ZigBee wireless technology is underway
介绍了一种近红外葡萄糖传感器控制器的设计与开发。该传感技术涉及在微制造腔室中对间隙流体进行采样,并以非破坏性和无试剂的方式测量流体的吸光度。葡萄糖水平是根据吸光度数据估计的。这项新技术依赖于葡萄糖在近红外光谱中的独特光学特性,将作为传感技术用于糖尿病原位治疗的反馈控制胰岛素输送系统。传感器元件将被植入人体的皮下组织,控制器将使传感器的操作数月,用户干预最少。该控制器的第一代样机已经开发并实现。目前,第一代原型系统的全面测试正在进行中,基于ZigBee无线技术的第二代原型系统的工作正在进行中
