A capacitive position sensing system has a pickup electrode, a shield electrode partially enclosing the pickup electrode, and an essentially grounded relatively movable target near the pickup electrodes;a capacitance-to-digital converter, and switching means for connecting each electrode in turn to the converter input or to ground. A capacitive position sensing method in the system includes measuring a first capacitance C1 of at least one pickup electrode set with the shield electrode set grounded, measuring a second capacitance C2 of at least one shield electrode set with the pickup electrode set grounded, and measuring a third capacitance C3 of the pickup electrode set and the shield electrode set connected together;and calculating a first result indicating a position of a target using the first capacitance C1, the second capacitance C2 and the third capacitance C3.

One of the critical steps in the post-production of paddy rice is to be stored in conditions that need to be controlled, especially the moisture content (MC) of the grains. The ability to determine and control moisture is a very important aspect of maintaining grain quality. This study aims to detect the MC of rice grain using UHF RFID technology. In this paper, three experiments have been carried out to detect the MC of rice in full rice grain-filled containers involving two conditions: with metal and without metal containers. The samples used consist of four 2 kg bags with MC levels of 11.875%, 16%, 20%, and 24%. The Received Signal Strength Indicator (RSSI) values were measured using a UHF handheld reader with two RFID tags to predict the MC. The results show an increasing RSSI pattern as the MC increases.

It is important and difficult for the complicated surface processing in mechanical industry. In this paper, an improved algorithm for trajectory planning is proposed in impeller surface processing by using 6-DOF cutting-robot. Taking a single finished path of the impeller blade as an example, the feedrate of the cutter, bow height error, cutter-orientation and position are planned by the B-spline interpolation algorithm, the best cutting trajectory is obtained. On the basis of trajectory planning, the optimal movement scheme of 6-DOF cutting-robot joints is obtained, the 6-DOF cutting-robot feedrate and trajectory smooth transition is achieved and the joints movement adaptive adjustment is completed. Finally, the angles, the angular velocitys of the joints and their interrelated properties are analyzed. The research works indicate that the robot joint angle curves are continuous and stable, which has met the requirements of smooth movement of the robot, and the results show that the trajectory planning is effective and practical. © The Authors, published by EDP Sciences, 2018.

Lane Change Assist, Lane Departure Warning, Lane Keeping System, and Automated Driving all require the sensors in vehicles to be able to detect the road and lane boundaries reliably and accurately under all circumstances. However, such functions rely currently solely on camera sensors, which in result unavoidably affects the stability of the whole system under certain extreme lighting conditions. Therefore, this paper shows a verification test result of a novel approach in lane boundary detection with an automotive radar and a specific kind of reflectors. A new approach of road course prediction and vehicle localization by utilizing its Range-Doppler characteristics is also presented in this paper. © 2018 IEEE.

SnO2 nanoparticles were synthesized by co-precipitation technique. The synthesized SnO2 nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and UV-visible diffused reflectance spectrometer (DRS). The XRD results addressed that the SnO2 nanoparticles was crystallized in rutile tetragonal structure. The SEM analysis confirms that the prepared nanopowder is composed of nanoparticles. Analysis of the DRS UV-Vis spectrum showed that the band gap of the synthesized SnO2 is to be ∼3.4 eV. The small cladding portion of the optical fiber was replaced with the synthesized nanoparticles. The ammonia sensing characteristics of the prepared SnO2 nanoparticles were analyzed for different wavelength ranges (red, yellow and blue) using polymethyl methacrylate fiber. It has been found that the synthesized SnO2 nanoparticles shows high sensitivity (∼23) in yellow wavelength range compared with red and blue wavelength ranges at room temperature. © 2018 Institute of Physics Publishing.

Geostationary Orbit (GEO) staring imaging technology is an important field of aerospace remote sensing technology research. In this Letter, an efficient method and system for hyperspectral imaging of geosynchronous orbit is realized by fusing diffractive optic and light field imaging technology. Large scale axial scanning of diffractive optic image spectrometer (DOIS) limits its application in GEO satellite. The emergence of the light field imaging technology provides a perfect solution for DOIS. Our system is a snapshot spectrometer that project the spectral and spatial information simultaneously onto a CCD detector. Here a spectrometer system that operates in the visible near infrared band is designed and the performance of the system is analyzed and evaluated. Experiments are shown to illustrate the performance improvement attained by the new model. Our analysis shows that the novel snapshot hyperspectral diffractive optic image spectrometer is a high resolution, compact, economical, rugged, programmable, hyperspectral imager that can be widely built for visible near infrared detection camera and high sensitivity astronomy satellite in GEO orbit and other fields. © Springer Nature Switzerland AG 2018.

Low cost, easily integrable photodetectors (PDs) for silicon (Si) photonics are still a bottleneck for photonic integrated circuits (PICs), especially for wavelengths above 1.8 µm. Multilayered platinum diselenide (PtSe2) is a semi-metallic two-dimensional (2D) material that can be synthesized below 450°C. We integrate PtSe2 based PDs directly by conformal growth on Si waveguides. The PDs operate at 1550 nm wavelength with a maximum responsivity of 11 mA/W and response times below 8.4 µs. Fourier transform infrared spectroscopy (FTIR) in the wavelength range from 1.25 µm to 28 µm indicates the suitability of PtSe2 for PDs far into the infrared wavelength range. Our PtSe2 PDs integrated by direct growth outperform PtSe2 PDs manufactured by standard 2D layer transfer. The combination of IR responsivity, chemical stability, selective and conformal growth at low temperatures, and the potential for high carrier mobility, make PtSe2 an attractive 2D material for optoelectronics and PICs.
