Orientation estimation can be executed by comparing the output of a 3D accelerometer and a 3D magnetometer with respectively gravity and local magnetic field vectors. For this purpose, an unscented Kalman filter was designed and tested. However, accelerometers also measure motion other than gravity, resulting in an error when estimating orientation directly from their output signals. Therefore, extra filters are added and the input parameters of the Kalman filter are dynamically varied, in order to reduce the effect of motion. Simulations are performed to tune the filter parameters for minimal motion influence without hampering actual orientation tracking. Satisfactory orientation tracking is performed with the filter using actual sensor nodes.

The aim of this paper is to present an efficient design approach called Partial Reconfiguration to design a sensors reading system for road safety. The soaring price of energy has lead designers to think of new approach to reduce the FPGA device utilization therefore the power consumption. The Partial Reconfiguration flow can exponentially increase the functionality of a single FPGA allowing a system to be implemented with fewer and smaller devices than otherwise require. The Partial Reconfiguration (PR) is a Feature that allows multiple design modules to time share physical resources. The partial reconfiguration module (PRM) can be swapped on the fly while the based design continues to operate. A Virtex 5 board an ICAP (Internal Configuration Access Port), ISE (Integrated Software Environment) 9.2 Service Pack 4 with the Partial Reconfiguration layout PR7, XPS (Xilinx Platform Studio) 9.2 Service Pack 2, PlanAhead 10.1.6 and Chipscope 9.2 Service Pack 4 will be used to demonstrate how useful that flow can be to read a certain number of sensors at different times for different applications.
本文的目的是提出一种称为部分重构的有效设计方法来设计道路安全传感器读取系统。不断飙升的能源价格促使设计人员考虑新的方法来降低FPGA器件的利用率，从而降低功耗。部分重新配置流程可以成倍地增加单个FPGA的功能，允许使用比其他方式更少和更小的设备实现系统。部分重构(Partial Reconfiguration, PR)是一种允许多个设计模块分时共享物理资源的特性。部分重构模块(PRM)可以在基础设计继续运行的情况下进行动态交换。将使用Virtex 5板ICAP(内部配置访问端口)，ISE(集成软件环境)9.2 Service Pack 4与部分重新配置布局PR7, XPS (Xilinx Platform Studio) 9.2 Service Pack 2, PlanAhead 10.1.6和Chipscope 9.2 Service Pack 4来演示该流程在不同时间读取不同应用程序的特定数量的传感器是多么有用。

By measuring both activity and energy of X-rays and gamma-radiation, a spectroscopic dosimeter provides an accurate estimate of biological damage due to ionizing radiation. A Multi-Channel-Analyzer (MCA) mixed-signal integrated circuit is in development to achieve a small form factor, and the low power consumption needed for this portable battery operated device.

Among marine algae species, Alexandrium minutum produces a phycotoxin called paralytic shellfish poisoning (PSP) that is introduced in the food chain through the ingestion of phytoplankton by shellfishs, and later by human consumers. Thus, in situ monitoring of A. minutum proliferation in coastal seawater is of great economical importance for marine resources exploitation. Here, we propose a rapid test for the detection of A. minutum by surface plasmon resonance spectroscopy. First, whole genomic DNA is extracted from the algae. Second, a 677 bp long portion of the 28S ribosomal DNA is amplified by PCR. Third, the PCR product is detected by surface plasmon resonance spectroscopy onto a DNA functionalized gold substrate.

Small amount of sand in oil pipelines can result in significant erosion in a very short time period. This Produced sand is a serious problem in many production situations. Installation of a system to monitor and quantify sand production from a well would be valuable to assist in optimizing well productivity and to detect sand as early as possible. We present a multi-sensor framework for sand detection. Wireless acoustic sensors are applied in networked data fusion systems for sand detection. The framework is designed to collect real time data from oil pipeline using acoustic sensors and flow analyzer. Fusion was implemented using two methods; Fuzzy Art (FA) and Moving Average Filter (MAF). A test bed was established from ten acoustic sensors. The flow rate was monitored as well in order to collect the data with the same flow rate. For each acoustic sensor the average percentage error between the observed sand rate and the actual sand rate is very high and inconsistence. However, using the fusion methods, the result shows that the average percentage error of the fusion methods is decreased.

The paper describes our work to explore the use of wireless sensor networks for industrial processes. Long term challenges including communication in a hostile environment, ad hoc networking, computing platforms, process imaging, sensing, miniaturization, compliance, micro-electromechanical systems and power harvesting are introduced. The issues are generic for applications to industrial process but the present work is targeted at monitoring grain storage. One requirement is to provide estimates of local position in a vessel and the paper describes progress towards using RF signal strength in the network for this purpose.

Ultrasonic sensors present one of the most cost-effective digital distance measurement systems available for mobile applications. Their effectiveness is limited, however, in applications involving complex environments and when information on sensor position is unavailable. This paper focuses on the implementation and limitations of ultrasonic sensors and system design considerations during development of an Electronic Travel Aid [ETA] for the visually impaired utilizing ultrasonic sensors and vibrotactile feedback. Our work with sensors included signal filtering and triangulation to improve performance characteristics of ultrasonic-based measurements. Additionally, we describe the use of computer modeling to aid in the design of ultrasonic sensor systems.

The paper presents an hardware solution for the realization of wireless sensors able to flow, without any anchorage, through the pipes used for fluid transportation, located on the terrain, but also under the ground surface. The designed sensors do not need any direct connection to the surface, communicate via wireless channels towards fixed stations positioned out of the ground, and provide a complete analysis of fluid pipes, in terms of survey, path identifications, damage recognition and leakage prevention. The electromagnetic components, particularly the antenna, are chosen in order to optimize the data transmission towards the surface. Antenna design and channel propagation modeling are based on a dedicated full-wave solution of the problem. To validate the introduced technological solution, an “ad-hoc” wireless sensor network has been designed and tested, thanks to the collaboration of the aqueduct company “Acquedotto del Monferrato”. In a dedicated test space, analyses were performed on water pipes of different dimensions at varying depths in the ground, up to 2.5 meters. Results show excellent performance and reliability.
本文提出了一种实现无线传感器的硬件解决方案，该无线传感器能够在没有任何锚固的情况下通过用于流体输送的管道，既可以在地形上流动，也可以在地表下流动。设计的传感器不需要与地面直接连接，通过无线通道与位于地面之外的固定站点通信，并在测量，路径识别，损坏识别和泄漏预防方面提供流体管道的完整分析。电磁元件，特别是天线的选择是为了优化数据向地面的传输。天线设计和信道传播建模都是基于一个专门的全波解决方案的问题。为了验证引入的技术解决方案，在“Acquedotto del Monferrato”渡槽公司的合作下，设计并测试了一个“特设”无线传感器网络。在专门的测试空间中，对不同深度的水管进行了不同尺寸的分析，最高可达2.5米。结果表明，该系统具有良好的性能和可靠性。
