This work covers an initial study on a long-term reliability assessment of a magnetic sensor system. Such systems feature the mechanical motion between a permanent magnet and a magnetic sensor and are widely used for multiple industrial applications. Repetitive readouts from multiple magnetic sensors and for different system states are performed for long time periods in order to assess reliability and to identify influences of external factors on the system such as temperature and stray fields on long measurements.

Objective: This paper introduces a simple wireless method to monitor the orientation and forces exerted by the cervix on the Arabin Pessary without introducing any active circuitry or using complicated imaging methods such as Magnetic Resonance Imaging (MRI) scans. The key technology behind the sensor is based on the measurement of the mutual coupling between two coils as the angle of the coil and the capacitance of the resonant circuit is varied. The change is measured using an external sensor circuit composed of a modified Grid Dip Oscillator (GDO). Methods: The authors have tested the device with a test rig to simulate the tissue barrier and the environment in which the Arabin Pessary is situated. Results: A frequency of approximately 560 kHz was used. The change in voltage with orientation follows a sinusoidal trend with the maximum voltage at 0o being 6.23V and the minimum voltage at 90o being 5.39V. The capacitance force sensor has a baseline capacitance of 32.5pF and yielded approximately 1pF change in capacitance for every 1N of force. This would result in a 0.765kHz/N sensitivity for a system with 560kHz baseline frequency. Conclusion: The designed sensor is capable of detecting, with good accuracy, both the forces exerted and the orientation of the Arabin. Significance: Correct placement of implanted devices can be critical to their function. Possessing the ability to monitor the properties of an implanted device in a noninvasive manner continuously would improve early detection of incorrect or failed placement minimizing negative health impacts and costs associated with complications.

Tunnelling Magneto-resistance (TMR) sensor as a pickup element for string instruments, in particular for electric guitars, is proposed in this paper. The proposed TMR based pickup showed several clear advantages compared to the presently used inductive type pickup units. The new scheme is much less sensitive to the disturbing electromagnetic fields, mainly because each string is excited using an a. c. current source at specific frequency and the signal conditioning circuit for the TMR sensor kept underneath the corresponding string is tuned to be sensitive to that particular frequency. This reduces the cross coupling effects, significantly. In addition, the output is not sensitive to the residual magnetic field of the string and the proposed sensor unit is compact compared to the conventional pick-up. In the proposed arrangement, an array of TMR sensors were placed right below the guitar strings and the output was recorded. For the feasibility study, the output signals were acquired using a Virtual Instrument developed in a LabVIEW environment. After extracting the vibration information from the TMR sensor data, with the help of envelope detection and a look-up table, the output obtained was compared with the output from a Laser Distance Sensor that directly measures the string vibration simultaneously. The results are matching.

This paper tracks the development of a Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) sensor array prototype, designed and built as both a standalone unit and for deployment on Unmanned Aerial Vehicles (UAV) and Remotely Operated Vehicles (ROV), primarily for Defence related missions. The CBRNE sensor array prototype employs multiple gas sensors, a radiation sensor, and other components that will allow it to be used as a flexible tool in hazardous environments. This tool will feature additional components including GPS for geo-tagging sensor readings, particularly on UAV and ROV missions and an LCD screen so that the prototype can function as a hand-held tool. The proposed sensor array will deliver mission critical data transmitted from the CBRNE sensor array prototype in different available formats, including KLV video metadata and a standalone graphical visualization display.

Ultrasonic sensing could be used to recognize objects with complex shapes like human faces. The high resolution range profile (HRRP), also called ultrasonic sonar image, is obtained by demodulating the faces' scatter (echo signal) of detection ultrasonic signal. Though HRRP feature represents the geometry of the human face, it's unstable because of the aspect sensitivity. In this paper, the HRRP and the robust feature extraction approach of ultrasonic sensing are investigated. The cause of HRRP sensitivity is analyzed based on the multi scatter centers model. And an average power feature extraction method is proposed. Experimental results show that the averaged HRRP feature is stable with the change of facial expressions and could be used in face recognition application. The feature extraction approach could also be used in other ultrasonic sonar detection and recognition applications.

This paper describes a preliminary test for sum-frequency generation (SFG) spectroscopy analysis of lipid polymer membranes. The SFG technique is used to analyze surface and structural information of molecules at gas-solid, gas-liquid, liquid-solid interfaces. A specially designed SFG system, which allows to analyze orientational polarization of polymer molecules at interfaces between a lipid polymer membrane and liquid/gas/solid, is being developed in our laboratory. A laser-induced damage threshold test of lipid polymer membranes was conducted in an early stage of this work.

With the rapid growth of the Internet of Things (IoT), there is a need for secure and scalable architectures for the IoT. This paper is a step towards this goal. We propose a set of security requirements for IoT systems and describe a novel security mechanism designed to those requirements. We divide the security threats and attacks on the IoT into five distinct categories, i.e. communications, device/services, users, mobility and integration of resources and employ them in developing the proposed requirements and mechanism. We argue that, by adopting such an approach in an IoT system, security can be achieved in a practical and comprehensive manner.

Usually physicians use acoustic stethoscope to detect abnormalities in the heart sound and predict abnormal conditions of human heart. As the frequency range and intensity of heart sound is very low, doctors are facing problems while detecting the cardiac sound and its abnormalities. To eradicate these severe problems it is required to design and develop an electronic stethoscope which would assist the doctor to analyze heart sound and to detect disease of the heart. Here an acoustic stethoscope along with microphone and preamplifier module is used in order to increase amplitude of the input sound signal received by the stethoscope. Soft scope of MATLAB program has also been used for analyzing the continuous set of cardiac sound and to detect its various characteristics like frequency, amplitude etc. It is aimed to design an electronic stethoscope which would assist the doctors to analyze heart sound and detect a disease condition of heart, but preliminarily we have achieved to detect different segments of the heart sound. Finally the sound signal received from the heart in the MATLAB program after filtering the noise out of it also has been plotted and analyzed in frequency domain.

This paper presents a microfluidic biosensor for micro particles and cells differentiation using cytometry. It is based on Electrical Bio-impedance Spectroscopy and able to perform cell by cell characterization at high flow rate. Sensing area is centered in platinum coplanar microelectrodes integrated in a 20×10 μm microchannel. Operating in laminar flow conditions, it permits to highly reduce risk of cell aggregation and focused cells and particles during measurement to improve reliability. Simulations by finite element method were performed to determinate fluid velocity profile along the channel and the effect of cell shifting during characterization. Comparison with measurement show that particles were correctly focused during measurement with a position shift less than 1μm. Measurement performed on 6 μm calibrated beads, demonstrate the possibility to determine precisely the microparticles size with an error less than 2%. Measurements performed with yeast cells, red blood cells compared to calibrated beads validate the possibility to use our sensor to detect very small dimensional changes of cells and particles, the precision being function of their impedance response.

PXIe is a modular instrumentation standard used in building electronic test equipment and modular laboratory instruments. Built on the PCIe bus standard, it provides high-speed transfer rates suitable for a wide range of applications. Instrumentation applications such as magnetic resonance imaging (MRI), generally has a high entry barrier due to high speed requirements and complexity. PXIe provides a good backplane option as the PCIe bus provides significant data bandwidth. However, the platform is inherently complex, usually contains proprietary IP and the solutions provided by vendors are often prohibitively expensive for some projects. To overcome these barriers, an open source PXIe platform has been developed. This consists of a PCIe I/O IP block for peripheral boards together with an associated device driver and application programmers interface (API) for the PCIe root complex hosted by the system controller. The design is capable of performing system controller initiated DMA transfers over PCIe in both directions. To further simplify system development, much use has been made of Xilinx based System on Module (SoM) units available from several vendors. Our example solution consists of (a) a PXIe system controller housing a Zynq based SoM mounted on a carrier board and running Linux and (b) a peripheral board based on an Artix SoM mounted on a carrier board and also hosting an FPGA Mezzanine Card (FMC) connector for further expansion.
