IEEE TITLE


Design and Implementation of a Web-Service-Based Public-Oriented Personalized Health Care Platform.



IEEE ABSTRACT


The use of information technology and management systems for the betterment of health care is more and more important and popular. However, existing efforts mainly focus on informatization of hospitals or medical institutions within the organizations, and few are directly oriented to the patients, their families, and other ordinary people. The strong demand for various medical and public health care services from customers calls for the creation of powerful individual-oriented personalized health care service systems. Service computing and related technologies can greatly help one in fulfilling this task. In this paper, we present PHISP: a Public-oriented Health care Information Service Platform, which is based on such technologies. It can support numerous health care tasks, provide individuals with many intelligent and personalized services, and support basic remote health care and guardianship. In order to realize the personalized customization and active recommendation of intelligent services for individuals, several key techniques for service composition are integrated, which can support branch and parallel control structures in the process models of composite services and are highlighted in this paper.

Autonomous smart sensor is a highly integrated turn-key device, operates independently and owns itself life cycle. Networked sensors exchange information with protocols; we designed an application-layer protocol named AgileSN making sensor nodes interoperable and interchangeable. AgileSN sensor node itself and captured data that protocol carried are self-descriptive, with these smart capabilities, sensor nodes can be automatically detected or searched by interested peers or sink nodes, and sensor data can be parsed dynamically on the fly without human intervention, made autonomous sensor nodes plug and play in the network world. Like WEB system, well accepted network protocol make network edsensors interchangeable and interoperable, universal sensor tools are possible to process sensed data. We have designed a component-based software tool for sensor application development. In this software environment, all application functionalities are realized through software components, each component is designed to finish a special task, like reading data from networked sensors, data processing, visual presentation, network or local file I/O, HMI, etc. sensor data is processed sequentially by several components through data flow. A component can operate in its own thread, carefully designed component makes the whole data processing flow operates in pipeline mode, greatly improve data processing throughput. Components and data routes can be created and destroyed at runtime, so the application system functionality is reconfigured. We apply the Petri Net tool to model components and the whole application system, investigate their function and performance, present a non-collision high-performance soft-bus for inter-component data transfer, investigate the hazard phenomenon that exists in a multi-input component, and propose technical means to eliminate it.



[2] A Virtual Machine-Based Programming Environment for Rapid Sensor Application Development


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=4291107&queryText%3Dsensor+application



In recent years, TinyOS and nesC are gradually becoming the de facto software development platform for implementing sensor applications. However, developing sensor applications is difficult for programmers since the programming paradigm used in nesC is different from that used in other popular programming languages. In view of this, we propose in this paper a virtual machine-based programming environment for rapid sensor application development. With the proposed programming environment, sensor applications are implemented in Tiny Java, which is a subset of Java programming language. Developing sensor applications is very similar as developing a traditional Java applications. Therefore, we believe that the proposed programming environment is able to speedup the development of sensor applications.

[4] Errors associated with the design, calibration and application of piezoresistive stress sensors in (100) silicon


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=296437&queryText%3Dsensor+application



Successful application of piezoresistive sensors for stress measurement requires both properly designed sensors and accurately calibrated values of the piezoresistive coefficients as well as a knowledge of potential sources of error that may be encountered during sensor application. In this work, results of analyses of errors associated with the design, calibration and application of piezoresistive stress sensors fabricated on (100) silicon are presented. In particular, sensor rotational alignment errors during fabrication and resistance measurements errors during calibration have strong effects on the values of the piezoresistive coefficients that are extracted from the calibration process. Also, calibration errors induced by mismatches in the resistor values and/or the actual piezoresistive coefficients of the various resistors in a sensor rosette have been quantified, and the importance of using data acquired only from well-matched resistor rosettes is demonstrated. Finally, it is shown that temperature measurement errors play a pivotal role in determining accuracy of the results obtained during calibration and application of these sensors.

http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=4387897&queryText%3Dsensor+application



Flexural plate wave (FPW) device has great potential for biological sensor application due to (1) isolation of its electric circuit from the medium being investigated, (2) low acoustic energy loss in liquid medium, and (3) simpler oscillator circuit design. Since FPW device can be fabricated onto silicon-based substrates by micromachining technology, it offers batch processing for economic sensor fabrication. In this study, ZnO was chosen as a piezoelectric material due to non-toxicity, and chemical and thermal stability for biological sensor application. RF magnetron sputtering and chemical solution deposition (CSD) were investigated for achieving strong c-axis orientation of ZnO films required to launch the acoustic wave in the device. Process parameters such as gas ratio, substrate types, and temperature, were varied for sputtering, and heat treatment and substrate types for CSD. Results showed that process parameters have a strong influence on the preferred orientation and microstructure of ZnO films. Uniform and dense microstructures of ZnO films were obtained by both fabrication methods. CSD method showed, however, stronger dependence of the preferred orientation on substrate types Mechanism for ZnO thin film growth will be discussed. FPW devices have been successfully integrated while less dependence on the substrates for sputtering due to energetic sputtered species. onto 4 inch Si-wafer with 22 different inter digitated electrodes.

This paper presents an investigation on sputtered titanium dioxide (TiO2) thin film for application in the Extended-Gate Field Effect Transistor (EGFET) sensor application for pH detection. The TiO2 thin film was fabricated on conductive indium-tin oxide (ITO) covered glass by using RF Sputtering method. An EGFET proof-of-concept setup was constructed using a commercial FET as the transducer and the TiO2/ITO structure was used for the extended gate. The sensor measurement was taken using semiconductor device parametric analyzer, constant-current constant-voltage biasing interfacing circuit and data logger to obtain the sensitivity and the characteristics for output voltage with respect to time. TiO2 thin film on ITO glass as the sensing membrane was compared with a bare ITO glass substrate for the extended gate. The TiO2/ITO glass exhibited the sensitivity of 42.1 mV/pH and good linearity of 0.9997 in the sensing range pH4, pH7 and pH10 which was better than the bare ITO glass sensitivity of 31.3 mV/pH and the linearity of 0.9868.

[17] Thin organic layers prepared by MAPLE for gas sensor application


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=4429933&queryText%3Dsensor+application



The Matrix Assisted Pulse Laser Evaporation (MAPLE) is a new progressive technology which has been found as a convenient method for thin organic (polymeric) film preparation. The goal of the work is to use prepared films for gas sensor application. The deposition was carried out by KrF excimer laser (wavelength 248 nm) in a chamber at working pressure of 3 Pa. Deposited materials (polypyrrole -PPY, Cu (II) para-tetramethylphenylporphyrine -CuTTMP, Indium acetyl-acetonate -InAcAc and Nickel phtalocyanine -NiPc) are embedded in frozen matrix (water, dimethylsulphoxide or chloroform) at the temperature of liquid nitrogen. The deposition can be described as photothermal process where the matrix molecules are preferentially evaporated due to their higher absorption coefficient on the laser wavelength. The molecules of deposited materials obtain sufficient kinetic energy through collective collisions with the vaporized matrix molecules, to be transferred into the gas phase. Small molecules of matrix are pumped away from the deposition chamber, while PPY, InAcAc, NiPc and CuTTMP molecules are incident on the sensor substrate, which is placed 35 mm far from the target. Thus thin organic layer is grown. Raman spectroscopy confirmed good similarity of chemical composition between source and deposited CuTTMP when using chloroform matrix. Prepared layers can be used as an element of safety gas detection systems as well as low-cost analytical tool for different gas concentration during industrial chemical production. Sensor responses to hydrogen, nitrogen dioxide and alcohol vapours in air were also measured. The obtained results of dc sensitivity (S -i.e. ratio of resistance in "pure" air and that in analysed gas mixture): S ~ 11 to 10,000 ppm of hydrogen, S ~1.5 to 1 ppm of nitrogen dioxide, S ~ 4 to 40 ppm of methanol, S ~ 5 to 20 ppm of ethanol and S ~ 6 to 2 ppm of propanol.



[18] Quality-of-information modeling and adapting for delay-sensitive sensor network applications


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6407659&queryText%3Dsensor+application



Acceptable Quality-of-Information (QoI) is essential for sensor network applications such as infrastructure health monitoring because it directly impacts public safety. However, it is a challenging problem to attain good QoI of sensor applications due to unpredictable environment noise, unreliable network communication, and varying requirements for wide variety of sensor applications. We believe the first step to addressing this challenge is to develop an application-independent QoI model. In this paper, we present a fundamental quality-of-information model based on signal-to-noise ratio. Our model addresses information quality by considering sensor measurement quality, network quality and sensor application requirements by end users. Furthermore, we develop a quality-aware scheduling framework which exploits an analytical queue model to calculate and adapt sensor node sampling rate and base station scheduling priority in order to optimize overall quality. Our results show that sensor measurement quality in terms of sampling rate, network quality in terms of loss rate and delay, all play significant roles in impacting overall quality. A QoI-aware scheduler thus is an effective approach to quantify information quality and adapt for unpredictable sensor networks.



[19] Building a generic platform for big sensor data application


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6691559&queryText%3Dsensor+application



The drive toward smart cities alongside the rising adoption of personal sensors is leading to a torrent of sensor data. While systems exist for storing and managing sensor data, the real value of such data is the insight which can be generated from it. However there is currently no platform which enables sensor data to be taken from collection, through use in models to produce useful data products. The architecture of such a platform is a current research question in the field of Big Data and Smart Cities. In this paper we explore five key challenges in this field and provide a response through a sensor data platform “Concinnity” which can take sensor data from collection to final product via a data repository and workflow system. This will enable rapid development of applications built on sensor data using data fusion and the integration and composition of models to form novel workflows. We summarize the key features of our approach, exploring how it enables value to be derived from sensor data efficiently.



[20]High resolution led-spectroscopy for sensor application in harsh environment


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=5488239&queryText%3Dsensor+application



The usage of novel LED-light sources for spectrometric application is shown and described in this paper. The utilization of fiber optical linkage to a simple open path absorption cell and a proper control of the light sources is the key to a robust and high resolved measurement system. A novel optical sensor system based on this approach is realized to measure the concentration of nitrogen dioxide, sulfur dioxide with a resolution below 1 ppm and ozone down to 30 ppb at a 4 cm single reflection cell in a fraction of a second measurement time. In this setup the emitted light from Light Emitting Diodes in the ultraviolet to the visible wavelength range was used. The optoelectronics and the control electronics are separated from the optical sensor head where the pure optical sensor effect takes place. Therefore the sensor can be used in harsh environment for instance in an exhaust tailpipe system or close to discharge plasma in strong electromagnetic fields or at high temperature. Furthermore the sensordesign is potentially low cost, quite small, long life and well suited for a large number of applications - from small battery powered hand held devices to industrial process control implementation. An LED-based sensor does not compete to laboratory chemical analytical devices but in many cases it is well suited for high resolved and fast online concentration measurements.

[22] Design, fabrication and testing of CNT based ISFET for Nano pH sensor application: A preliminary study


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=5229844&pageNumber%3D3%26queryText%3DSensor+Application



In recent years, there has been increasing interest in monitoring and controlling of pH. It has become an important aspect of many industrial wastewater treatment processes. At the same time, the demand for smaller electronic devices used for various industrial and commercial applications has greatly increased. Micro and nano materials, such as Carbon Nanotubes (CNTs), are known for their excellent electrical and mechanical properties, as well as for their small size, therefore they are good candidates to manufacture micro or nano electronic devices. These devices can be used for pH control. However, this cannot be achieved unless CNTs with metallic or semiconducting band structures can be successfully deposited and separated. In these processes, microchip fabrication and deposition of CNTs using Dielectrophoresis (DEP) are involved. Comparing with some traditional pH sensors, which mainly consist of Ion-Sensitive Field Effect Transistor (ISFET), signal operational amplifier and Analog Digital Convert (ADC), Nano pH sensor with CNTs may provide more benefits owing to their unique properties. For example, 70-80% of multi-walled CNTs (MWCNTs) are metallic and have high current density, which means this kind of micro device has a linear relationship of I-V characteristic and can produce signal strong enough to make operational amplifying circuits unnecessary. In addition, to manufacture smaller devices more functional becomes possible as CNTs are tiny and compact.

This paper reports a novel circuit to supply constant heating power to the micro-hotplate for integrated gas sensor applications. The circuit is designed so that the heating power is maintained constant in spite of the change of heater resistance value due to process variations. By controlling the biasing current of the power control circuit, the heating power can be controlled linearly. The circuit is realized using CMOS. Simulation shows that the heating power can be controlled at ±0.4% with ±50% changes in heating resistance.



[24] Silicon-based integrated field emission electron sources for sensor application


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6004541&pageNumber%3D3%26queryText%3DSensor+Application



We report on the design, fabrication and characterization of p-type silicon field emitter arrays for the application in compact fast switchable electron sources. Since standard silicon technology has been used to prepare the devices, they can be easily integrated with other silicon based sensors and electronic components, too. The emitter arrays consist of approx. 3×105 tips per cm2, with a tip radius less than 20 nm. By using self-aligned processes, an integrated gate electrode with a diameter of ~3 μm was placed concentrically around the tips. A mesh of silicon-beams with a grating period of 100 μm and beam width of 20 μm forms the anode of the electron source. A glass wafer (thickness 300 μm) acts as spacer between anode and Si-tip cathode. Characterization of the field emission properties of the emitter arrays was performed by high resolution field emission scanning microscopy. The emitter arrays exhibit a highly stable and very homogeneous emission. A maximum stable current of 0.1 μA per tip was found. A saturation level in the voltage current characteristics, which was found at around 10 nA, supports current stabilisation and will enable optical modulation of the emission current.

http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=1067682&pageNumber%3D3%26queryText%3DSensor+Application



The fluxgate magnetometer, which has been used for many years in the measurement of dc or low frequency magnetic fields, may also be adapted to the quantitative measurement of magnetic field impulses of short duration. The impulse is effectively stored in the sensor and read out during one or more excitation periods. This storage is accomplished by means of a shorted coil of suitable time constant wound around the sensor core. A possible application is the location and measurement of the amount of charge transfer in lightning flashes.



[28] Critical view on the current sensor application for self-timing in VLSI systems


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=486397&pageNumber%3D3%26queryText%3DSensor+Application



To solve the problem of global synchronization in massively parallel VLSI systems, it is necessary to organize asynchronous interaction between system blocks. The possibility of applying current sensors for detection of the end of signal transitions to construct asynchronous blocks in CMOS-technology is discussed. For known current sensors, their design principles and characteristics are analysed. Two ways of organizing the interaction between circuits with current sensors are suggested. Stubborn problems of using the known current sensors that appear due to the imperfection of their characteristics are formulated. A current sensor is suggested that removes the major of these problems but is capable of working only with a particular circuit class. However, simulation results indicated that using even such sensors is not efficient enough.

[33] Electrophoretic deposition of SnO2 nanoparticles in non-aqueous medium for sensor applications


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6411500&pageNumber%3D3%26queryText%3DSensor+Application



Nanosized SnO2 based sensors are widely used for gas sensing applications because of their low operating temperature and high surface area. SnO2 films are conventionally deposited by chemical vapor deposition, evaporation, sol-gel and sputtering which are very expensive, time consuming processes and complex. In contrast, electro phoretic deposition (EPD) is simple, cost effective which makes it possible to fabricate reliable porous coatings. The aim of this work is to deposit porous and homogenous SnO2 films by using EPD and to investigate the surface morphology of the films for gas sensor production. In this study nanosized SnO2 (60nm) particles were used in non-aqueous mediums with and without iodine to prepare stabilized EPD suspension. Homogeneous and porous film layers were processed and analyzed at various time and voltages. The results showed that highly porous, crack free and homogeneous SnO2 films on Pt coated alumina substrate were achieved for 5 and 15 seconds at 100V EPD parameters. Optimum sintering between the SnO2 nanoparticles was observed at 500oC. Deposited film thickness of 5 μm was measured by scanning electron microscopy. According to initial results, EPD deposited SnO2 films showed high sensitivity to liquified petroleum gas (LPG) at various gas concentration and operation temperature.



[34] Initial results on magnetic induction tomography hardware measurement using hall effect sensor application


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=5742189&pageNumber%3D3%26queryText%3DSensor+Application



Magnetic induction tomography (MIT) is among the new technology that compliment other tomography methods such as ultrasonic, optical, capacitance and several others. This type of tomography applies the magnetic field to detect the existence of the object that is going to image. Several methods are possible in constructing the magnetic induction hardware. Most of the researchers used coils for both transmitter and receiver which are more complicated and need large space. The Hall Effect sensors (HES) have the potential of replacing the coil at the receiver side since it has the ability to measure the value of magnetic field strength and convert it to voltage value. This concept is same as the ultrasonic sensors used in ultrasonic tomography instrumentation hardware. The results have shown that the pattern of capture data by hall effect sensor are almost the same pattern for all 8 sensors for each material used. Thishave given positive sign that HES is capable to be applied in MIT measurement system.

This research is intended to study the combination of MOSFET and photoconductive material to perform as a single device light sensor MOSFET (LiSFET) using standard lithography process. Photolithography (also called optical lithography) has long been used to transfer circuit patterns from a template called photomask (or simply mask) on to silicon wafers during integrated circuit (IC) fabrication. When a light source is used to project the mask image onto the wafer, the image quality is often affected by the performance of the imaging system (also called exposure system).

http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=703891&pageNumber%3D3%26queryText%3DSensor+Application



A programmable hybrid neural network architecture has been used to implement a smart optical sensor with focal-plane pattern classification for a flexible manufacturing cell environment. The network contains an integrated photosensitive array based on modified photo BJTs as input to a fully-connected multilayer feedforward (MLFF) neural classifier. The architecture features a distributed neuron realization that employs a number of active nonlinear resistor circuits operating in parallel. It minimizes the effect of parameter variations due to non-uniform device fabrication over the die surface. Moreover, due to the modularity of the architecture and locality of interconnections, synaptic density has been doubled in comparison with a conventional realization. A photosensor-classifier chip consisting of a 2-D array of 64 neural-based smart pixels and additional neural network circuits has been fabricated. The proposed architecture has been implemented in both CMOS and BiCMOS process technologies as part of a sensor optimization study.

[42]Band gap tuning of carbon nanotubes for sensor and interconnect applications — A quantum simulation study


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6198046&pageNumber%3D4%26queryText%3Dsensor+application



Carbon nano tubes (CNTs) are a promising material for novel sensor and interconnect applications. In both cases, the device performance depends strongly on the electronic properties of the tubes. Methods for tuning the electronic structure and especially the band gap are highly desirable. A computational study of cobalt decorated CNTs, by means of density functional theory, reveals that very few cobalt atoms can have a significant impact on the electronic structure, turning semiconducting CNTs into the metallic state. This is further verified by quantum transport simulations. The influence of different amounts of cobalt is also investigated.

http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=997711&pageNumber%3D4%26queryText%3Dsensor+application



In the field of smart sensors new applications named electronic noses are now developed and used for environmental air quality control. In our case we are developing such an application based on a tin oxide gas sensor array for the main detection of two gases : a refrigerant gas Forane 134a (Hydro fluorocarbon) and a carbonic gas. Due to the high sensitivity to humidity observed for these types ofsensors, we study here the ability of our system to well discriminate the target gases and also their concentrations whatever the relative humidity rate in a wide range. By using a multidimensional pattern recognition method (Discriminant Factorial Analysis) these learning process results are presented and the created decisive laws are used to successfully identify unknown cases.



[44]A high C-axial ZnO thin-film for piezoelectric sensor application


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6411227&pageNumber%3D4%26queryText%3Dsensor+application



To effectively reduce the insertion loss of piezoelectric micro sensors, this study aims to develop a high C-axis orientation ZnO piezoelectric thin film by magnetic RF sputtering system. The substrate temperature, RF power and argon/oxygen (Ar/O2) flow ratio of sputtering process are varied and their influence on the grain size, pore density and X-ray diffraction (XRD) intensity of the eight sputtered ZnO thin films deposited on Si/Cr/Au substrate are investigated. Under the optimum condition obtained in this research (temperature: 100 °C, RF power: 350 W and Ar/O2 flow ratio: 30sccm/13sccm), the average grain size of the optimized ZnO thin film is only about 74.7 nm and near zero pore density can be achieved. In addition, a very high XRD diffraction intensity (12,500 a.u.) and a 34.1° diffraction angle of the optimized ZnO thin film, which matches to the 34.422° diffraction angle of standard C-axis ZnO film, can be demonstrated in this work. Under the optimized ZnO deposition condition, a very low insertion loss (-11 dB) and center frequency (12.11 MHz) of the ZnO-based FPW device can be obtained.



[45]Soft sensor application in vehicle yaw rate measurement based on Kalman filter and vehicle dynamics


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=1252704&pageNumber%3D4%26queryText%3Dsensor+application



The accurate measurement of vehicle yaw rate is vital for vehicle dynamics control, such as yaw control and traction control. Generally, vehicle yaw rate is measured by gyro that costs too much to be used commercially as an on-vehicle sensor. Based on soft sensor technique in inferential control theory, a novel method for the estimation of vehicle yaw rate is proposed. The estimation is based on Kalman filter and 2 degree-of-freedom vehicle dynamic models to realize the estimation of way rate of linear minimize mean square error. Results of simulation and experiment show an accurate and low-cost estimation of yaw rate is achieved and soft sensor estimation method is feasible in measurement of vehicle state.



[46]Mesostructured and mesoporous metal oxide films for optical waveguide-based gas sensor application


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=1426424&pageNumber%3D3%26queryText%3Dsensor+application



A glass planar optical waveguide with a top layer of mesostructured or mesoporous metal oxide films, such as TiO2, SnO2, ZnO2, ZrO2, WO3, Al2O3, Ta2O5 or Nb2O5, was proposed for chemical, biological and gas sensor applications. To demonstrate the application feasibility of such a composite waveguide structure, a slide glass substrate with a tin-diffused layer was dip-coated with a mesostructured hybrid film of peroxopolytungstic acid and block copolymer template. On the basis of the polarimetric interference, the resulting waveguide has been demonstrated to have a high sensitivity to ammonia in air at room temperature.



[47]Photopolymerization and photostructuring of molecularly imprinted polymers for sensor applications


http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6411425&pageNumber%3D3%26queryText%3Dsensor+application



Molecularly Imprinted Polymers (MIP) were prepared by photochemical route. Photoinduced polymerization was used to achieve the preparation of the MIP and at the same time spatially controlled irradiation allowed shaping the material to confer it an optical function useful for interrogation. Such route significantly simplifies the integration of MIP for sensor applications. Specific photopolymerizable MIP were designed for photopolymerization at different wavelengths and advanced methods of photopatterning were used including optical near-field, interference or self-guiding lithography. Photopatterning appears thereby as one of the most suitable methods for patterning MIP at the micro and nano scale, directly on the transducer surface.

In this letter, we report the piezoresistive effect at room temperature of a AlxGa1-xAs thin film, which has been integrated on the beams of an accelerometer as sensing elements to detect the external strain.

For the rapid prototyping of mixed-signal systems in the automotive industry, tools such as MatrixX or Simulink permit the validation of control concepts. However, the physical properties of analog circuits must often be modeled. In this case, behavioral models are created and used in a real time simulation as a virtual prototype. This paper gives an overview of methods that allow us to generate analog circuit models in C++, these portions of C++ can be used as a virtual prototype. In order to achieve the necessary performance, the generation of behavioral models is combined with very fast simulation methods.

Sensor Application Basics


Industry continually strives to develop product faster and more cost effectively. By automating processes, manufacturers can realize these goals while maintaining higher levels of quality and reliability. Presence sensing technology is used to monitor, regulate and control these processes. More specifically, presence sensors help verify that critical process steps are completed as intended. The first section of this chapter covers the terminology and basic operating principles common to all sensors; the remainder outlines a methodology for reviewing potential applications and selecting the best sensor for the job. Later chapters will discuss, in some detail, the most prevalent technologies and their application:

  • What Is a Sensor?


    A sensor is a device for detecting and signalling a changing condition. And what is this “changing condition”? Often this is simply the presence or absence of an object or material (discrete sensing). It can also be a measurable quantity like a change in distance, size or color (analog sensing). This information, or the sensor’s output, is the basis for the monitoring and control of a manufacturing process.The Sensors Technologies Program integrates with most other programs in NIFA. Nearly all aspects of production, processing, and management in agricultural and food systems (including forestry and natural resources) involve measurement of product/resource attributes (such as quantity, quality, size, condition) or their environment (such as food impurities, or agricultural/forest air, water, and soils).

    Rural economies and their infrastructures are also affected. Their biometric activities include inspection, monitoring, tracking, inventory, and valuation. The number of measurement variables—and their measurement frequency and level of detail—demands automated, high-resolution, and rapid technologies. In the interests of efficiency and wise stewardship, increasingly voluminous data are collected that must be further analyzed, interpreted, and applied to support intelligent decision making. Advances in biometrology and information technologies are required to address our need for timely and reliable information that has temporal and spatial relevance .Food safety and quality represent one of the greatest public issues/concerns nationwide. Safety and quality depend on inspection and monitoring methods that can detect contaminants and discriminate defective (or poor quality) products. Whereas manual, microscopic, or bio-assay inspections cannot be performed quickly and accurately on 100 percent of any food product, sensor and instrumentation technologies currently under development and testing promise to offer inspection capabilities that are accurate, fast (in real time), and consistent. These technologies can range from detecting: internal bruising of apples to 10 cells of Listeria (a particularly virulent food pathogen) to insect infestations in a ship's cargo of grain.

    Environmental quality is another area where sensor-based monitoring can be helpful. For example, animal feeding operators can use air quality monitoring around confined animals to keep ammonia or odor emission within acceptable limits. Water monitoring for nitrogen and phosphorus runoff from agricultural lands can help regulate freshwater algae blooms and costal-zone hypoxia. An ability to quickly and accurately measure carbon sequestration in soils can facilitate more widespread application of a carbon-credit and trading market place.These types of measurement activities create special problems, however, because the elements being measured are molecular and they need to be quantified over large land areas. Nevertheless, these applications are scientifically possible; it remains to develop the engineering and technology capability to make them economical and practical .Remote sensing and animal health and feeding applications are covered by the Precision Farming program page.
