In the last few years, forward-looking sonar devices have emerged as a powerful perception alternative for those underwater environments with reduced visibility. Thanks to its capability to deliver high quality acoustic images at a near-video frame rate, they can be regarded as the analogous tool of optical cameras for operations conducted in turbid waters. However, despite the analogy, the particularities of forward-looking sonar imagery pose a significant challenge to the techniques typically used on optical images and, especially, to the key step of image registration, essential in applications like mosaicing, sonar-aided navigation or image denoising. In this sense, previous investigations have encouraged the use of spectral registration methods as a promising alternative over the traditional feature-based registration approaches used on optical images. In this paper, we propose to improve the spectral registration of forward-looking sonar images with an adaptive filtering technique that allows to cope with the noise and variability inherent to the forward-looking sonar image registration problem. Results show that by using the proposed filtering we achieve a more accurate pairwise alignment of the sonar images that can benefit subsequent processing in many applications.
在过去的几年里,前视声纳设备已经成为能见度较低的水下环境的强大感知替代方案。由于它能够以接近视频的帧率提供高质量的声学图像,它们可以被视为在浑浊水域进行操作的光学相机的类似工具。然而,尽管有这样的类比,但前视声纳图像的特殊性对光学图像的典型应用技术构成了重大挑战,特别是对图像配准的关键步骤,这在拼接、声纳辅助导航或图像去噪等应用中至关重要。从这个意义上说,以前的研究鼓励使用光谱配准方法作为传统的基于特征的光学图像配准方法的有前途的替代方法。在本文中,我们提出了一种自适应滤波技术来改进前视声纳图像的光谱配准,该技术可以处理前视声纳图像配准问题中固有的噪声和可变性。结果表明,采用该滤波方法可以实现更精确的声呐图像成对对准,有利于后续处理。

Metal-Oxide Semiconductor gas sensors are small in size and affordable, which makes them appropriate for implementation in battery-powered wearable sensing devices. However, their big flaw is the need to be heated to a certain temperature to react with the gas from the atmosphere, which consumes energy and drains the battery of the sensing device. In this paper we experimentally evaluate the possibilities to determine changes in gas concentration from the very beginning of the sensor's response. Our experiments in controlled conditions show that the increment of CO concentration could be determined in the first 65 ms of sensor heating, while the sensing layer is still in its transient state. That indicates the possibility of more than 30 times energy savings compared to the experiments where the CO concentration is determined after the sensing layer reaches stable state.
金属氧化物半导体气体传感器体积小,价格实惠,适合在电池供电的可穿戴传感设备中实施。然而,它们最大的缺点是需要被加热到一定的温度才能与大气中的气体发生反应,这会消耗能量并耗尽传感装置的电池。在本文中,我们通过实验评估了从传感器响应的一开始就确定气体浓度变化的可能性。我们在可控条件下的实验表明,在传感器加热的前65ms,当传感层仍处于瞬态时,可以确定CO浓度的增量。这表明,与在传感层达到稳定状态后确定CO浓度的实验相比,可能节省30倍以上的能源。

This paper describes how to use sensor information in international disaster management operations. The focus is on enabling sensor interoperability by using standardized interfaces. For this work the Open Geospatial Consortium (OGC) Sensor Observation Service (SOS) is used to exchange sensor information between different systems. Further individual sensor values have to be interpreted to bring benefit to commanders in disaster operations. We are proposing a Sensor Fusion Engine to combine sensor data stemming from heterogeneous sources and provide a condensed output in different standard formats and protocols. An example of such a format is the Common Alerting Protocol (CAP) which is a standardized interface used in disaster operations. Real world deployments in large scale disaster exercises have shown the applicability of the approach.
本文介绍了如何在国际灾害管理业务中使用传感器信息。重点是通过使用标准化接口实现传感器的互操作性。在这项工作中,使用开放地理空间联盟(OGC)传感器观测服务(SOS)在不同系统之间交换传感器信息。此外,还必须对单个传感器的值进行解释,以便在救灾行动中为指挥官带来好处。我们提出了一个传感器融合引擎来结合来自不同来源的传感器数据,并提供不同标准格式和协议的压缩输出。这种格式的一个例子是公共警报协议(CAP),它是灾难操作中使用的标准化接口。大规模灾难演习中的实际部署表明了该方法的适用性。

The tragic Deepwater Horizon accident in the Gulf of Mexico in 2010 as well as increase in deepwater offshore activity have increased public interest in counter-measures available for sub-surface releases of hydrocarbons. Available remote-sensing techniques are efficient and well developed for surface disasters but they are not useful underwater. Along these lines, this paper analyzes application of Autonomous Underwater Vehicles (AUV) with integrated submersible fluorometer for underwater detection of hydrocarbons. Experiments with rhodamine, which was used as a replacement for oil, showed that the proposed system can be efficiently used both as an input into numerical model and consequent visualization of spatial distribution of pollutant.
2010年发生在墨西哥湾的“深水地平线”(Deepwater Horizon)悲剧事故,以及深水海上活动的增加,增加了公众对地下碳氢化合物释放对策的兴趣。现有的遥感技术对水面灾害来说是有效和发达的,但在水下却没有用处。在此基础上,分析了集成水下荧光仪的自主水下航行器(AUV)在水下烃类探测中的应用。用罗丹明代替石油进行的实验表明,该系统既可以有效地作为数值模型的输入,也可以有效地显示污染物的空间分布。

Advances in animal tracking technology allow for improvement in farm resource management, animal welfare and the possibility of an overall reduction in running costs. We describe a light-weight solar-powered position sensor tag for livestock and a corresponding base station. The livestock ear tag weighs less than 40g and utilises 868MHz SRD/ISM frequency band for telemetry. This provides configurable wireless connection for data retrieval triggered by a base station, reducing the overall power consumption of the tags. Data transmission range is 2.4km line of sight and 1km typical. Static testing of the position sensor yields a circular error probable of 6 ±2 metres.

Using smartglasses for utility-meter reading 使用智能眼镜读取电能表
Pub Date : 2015-04-13 DOI: 10.1109/SAS.2015.7133649
A. Depari, C. M. D. Dominicis, A. Flammini, E. Sisinni, Luca Fasanotti, P. Gritti
Despite the increasing adoption of smart meters, especially for electrical power measurements, a very large number of utility inspectors manually execute readings of legacy analog meters (e.g., for gas or water utilities). Unfortunately, manual data collection generates a lot of paperworks and is clearly error prone. In this work, authors suggest the adoption of smartglasses to automatize this process. In particular, the embedded camera is used for barcode scanning (in order to identify the user) and for recognizing the meter dial values. The availability of an Internet connection finally allows for exploiting cloud-based repository solutions. In that way data can be easily accessed from both utility employees and customers using simple web services. A preliminary prototype based on the Vuzix M100 device has been realized. Some tests have been carried out, confirming the feasibility of the proposed approach.
尽管越来越多地采用智能电表,特别是用于电力测量,但大量的公用事业检查员手动执行传统模拟电表的读数(例如,用于燃气或水公用事业)。不幸的是,手动收集数据会产生大量的文书工作,而且很容易出错。在这项工作中,作者建议采用智能眼镜来自动化这一过程。特别地,嵌入式摄像机用于条形码扫描(以便识别用户)和识别仪表表盘值。Internet连接的可用性最终允许利用基于云的存储库解决方案。通过这种方式,可以使用简单的web服务轻松地从公用事业员工和客户那里访问数据。基于Vuzix M100设备的初步原型已经实现。已经进行了一些试验,证实了所提议的方法的可行性。

The paper presents a novel model-based algorithm for classifying buried metallic targets using spatial and temporal response properties of a pulse induction metal detector mounted on a mobile robot for autonomous landmine detection. In the proposed approach, we firstly derive a simplified analytical model for spatial distribution of the primary magnetic field that corresponds to transmitter/receiver coil geometry of a given metal detector. The sensing head model is then coupled to a metallic target analytical dipole model whose parameters are the magnetic polarizability tensor and the target location. Finally, the forward sensor/target model is fitted to sensor data obtained by spatially mapping the suspected target area using a mobile robot. Inverted magnetic polarizability tensors corresponding to sensor data acquired at different time instances (gates) are used for target characterization and classification. The algorithm is experimentally evaluated on a dataset collected from a test site containing surrogate mines (metallic spheres) and clutter targets.

Wireless Sensor Networks (WSNs) are at the verge of a broad acceptance in demanding industrial applications. Nodes must fulfill key requirements like reliability and deterministic communication, but also energy autarky in order to allow maintenance-free systems. In this paper a system combining low power, robust communication with appropriate methods for energy harvesting and energy management is suggested. By comparing two alternative variants for power-management, constraints of a solar-cell powered node design are derived. The resulting system demonstrates energy sufficiency at standard industrial indoor lighting conditions of 1300 lx for sensor nodes sampling temperature values at 10 Hz and transmitting once per second.

The characteristic bio-impedance spectra of a biological sample can provide important information about its cellular structure, and further, infer useful information about the physical and chemical condition of the sample. In this paper, we present the background detail of a magnetic induction spectroscopy system for non-contact bio-impedance measurements, and some results using this system to obtain the relative permittivity spectra of a range of fruit and vegetable samples, over a frequency range from 160 kHz to 2.5 MHz. Relative permittivity is found to decrease with respect to frequency for each sample tested. This shows clear evidence of dispersion occurring within the samples across the investigated bandwidth.

Application of power sensors in the control and monitoring of a residential microgrid 电力传感器在住宅微电网控制与监测中的应用

Advancements in sensor and metering technologies enable us to affordably collect more data than ever before and this data can be used to revolutionize the power industry. The ability to sense and monitor power characteristics in near real time and feed this information to control systems operating to optimize the grid enables better operation of both large and small scale power systems. Real-time power sensors working with a near real-time control system is necessary for a microgrid which has intermittent renewable generation and time varying loads. Knowing how much energy is flowing through the system is crucial for stable operation while islanded and is important to maintain economic feasibility. The application of advancements in cloud communications and embedded sensors can be used to augment the control of a residential microgrid through the real time data collection and control of both loads and generation resources. Using an advanced sub-metering system to monitor the flow of energy through the microgrid, a connection to the ISO's energy market, and local environmental data provides efficient operation and insight into the near real-time operation of the system. The data can also be logged for future analysis external to the system to allow for better future development of control strategies and can be used to make better predictions of energy needs and costs. These predictions can be used to ensure the renewable energy is used in the most economic manner ensuring the best possible equivalent price of energy. Such an integrated and predictive system can also store thermal energy inaugurating a paradigm shift from a “demand response market” to one that becomes an “availability responsive market”.
