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

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

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

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

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

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
