Digital Compasses for Orientation-Tilt Monitoring in Offshore Deep-Sea Infrastructures: The KM3NeT Case 用于近海深海基础设施定向倾斜监测的数字罗盘:KM3NeT案例

: The KM3NeT Collaboration is currently constructing two neutrino detectors in the depths of the Mediterranean Sea. An excellent angular resolution is necessary for an accurate reconstruction of the neutrino direction. Precise knowledge of the position and orientation of the detector compo-nents is mandatory in order to achieve the required angular resolution. For High-Energy Neutrino Astrophysics program, an angular resolution < 0.05 deg is expected for the sparser detector if synchronization ~1 ns, positioning < 20 cm, and orientation < 3 deg, for the Detection Units, are guar-anteed. The KM3NeT orientation- tilt system known as “Digital Compasses”, is an Attitude and Heading Reference System (AHRS) board coupled to the inner Central Logic Boards of the detection modules. The AHRS integrates a 3D-magnetometer containing an Anisotropic Magnetoresistive Sensor to estimate the Earth’s magnetic field, and a 3D -accelerometer equipped with a Micro Electro-Mechanical System that estimates the acceleration field intensity. The performance of the Digital Compasses, together with the reconstruction of orientation-tilt magnitudes and calibration, will be presented and discussed in this contribution.
KM3NeT合作项目目前正在地中海深处建造两个中微子探测器。为了精确地重建中微子的方向,极好的角分辨率是必要的。为了达到所需的角度分辨率,必须精确了解探测器组件的位置和方向。对于高能中微子天体物理项目,如果保证同步~1 ns,定位< 20 cm,定位< 3°,稀疏探测器的角分辨率< 0.05°。KM3NeT定向倾斜系统被称为“数字罗盘”,是一个姿态和航向参考系统(AHRS)板,与检测模块的内部中央逻辑板耦合。AHRS集成了一个包含各向异性磁阻传感器的3D磁强计,用于估计地球磁场,以及一个配备微机电系统的3D加速度计,用于估计加速度场强度。本文将介绍和讨论数字罗盘的性能,以及定向-倾斜幅度的重建和校准。

Arduino-Based Sensing Platform for Rapid, Low-Cost, and High-Sensitivity Detection and Quantification of Analytes in Fluidic Samples 基于arduino的传感平台,用于快速,低成本,高灵敏度检测和定量流体样品中的分析物

Lateral flow assays (LFAs;aka. rapid tests) are inexpensive paper-based devices for rapid and specific detection of analyte of interest (e.g., COVID virus) in fluidic samples. Areas of application of LFAs cover a broad spectrum, spanning from agriculture to food/water safety to point-of-care medical testing and, most recently, to detection of COVID-19 infection. While these low-cost and rapid tests are specific to the target analyte, their sensitivity and limit of detection are far inferior to their laboratory-based counterparts. In addition, rapid tests normally cannot quantify the concentration of target analyte and only provide qualitative/binary detection. We have developed a low-cost, end-user sensing platform that significantly improves the sensitivity of rapid tests. The developed platform is based on Arduino and utilizes low-cost far infrared, single-element detectors to offer sensitive and semi-quantitative results from commercially available rapid tests. The sensing paradigm integrated to the low-cost device is based on radiometric detection of photothermal responses of rapid tests in the frequency domain when exposed to modulated laser excitation. As a proof of principle, we studied commercially available rapid tests for detection of THC (the principal psychoactive constituent of cannabis) in oral fluid with different concentrations of control positive solutions and, subsequently, interpret them with the developed sensor. Results suggest that the developed end-user sensor is not only able to improve the detection limit of the rapid test by approximately an order of magnitude from 25 ng/mL to 5 ng/mL, but also offers the ability to obtain semi-quantitative insight into concentration of THC in the fluidic samples. © 2022 by the authors.
横向流动试验(LFAs)快速检测)是一种廉价的纸质设备,用于快速和特异性检测流体样品中的感兴趣的分析物(例如,COVID病毒)。lfa的应用领域非常广泛,从农业到食品/水安全,再到护理点医疗检测,以及最近的COVID-19感染检测。虽然这些低成本和快速的检测是针对目标分析物的,但它们的灵敏度和检测限远不如基于实验室的检测方法。此外,快速检测通常不能量化目标分析物的浓度,只能提供定性/二元检测。我们开发了一个低成本的终端用户传感平台,显著提高了快速测试的灵敏度。开发的平台基于Arduino,利用低成本的远红外单元素探测器,从商业上可用的快速测试中提供敏感和半定量的结果。集成到低成本设备的传感范例是基于暴露于调制激光激发时在频域快速测试的光热响应的辐射检测。作为原理证明,我们研究了市售的快速检测方法,用于检测含有不同浓度对照阳性溶液的口服液中的四氢大麻酚(大麻的主要精神活性成分),然后用开发的传感器对其进行解释。结果表明,所开发的终端用户传感器不仅能够将快速测试的检测限提高约一个数量级,从25 ng/mL提高到5 ng/mL,而且还提供了对流体样品中四氢大麻酚浓度进行半定量分析的能力。©2022作者所有。
