Characterization and Performance Estimation of a MEMS Spirometer

引用

Procedia engineering 2016年 168卷 1020-1023页

作者： Sahar Habibiabad Yeşim Serinağaoğlu Doğrusöz Mustafa İlker Beyaz Graduate School of Natural and Applied Sciences – Biomedical Engineering Program Middle East Technical University Ankara 06800 TURKEY Department of Electrical and Electronics Engineering Middle East Technical University Ankara 06800 TURKEY Department of Electrical and Electronics Engineering Antalya International University Antalya 07190 TURKEY

The electrical characteristics and performance estimation of a MEMS spirometer is reported. The device design incorporates a silicon turbine, integrated magnets, ball bearings, and stators having planar coils. Pneumatic actuation of the turbine with tangential gas flow induces voltages on the stators. Spirometer parameters including breathing flow rate and lung capacity can be determined from the induced voltage amplitude and frequency. Two 12-pole stators with 25- and 50-turns per pole were fabricated. The resistance and inductance values were measured to be 3.9 kΩ and 2.6 mH, and 15.8 kΩ and 10.3 mH, respectively. The expected sensitivity of the devices was calculated to be 0.1 V/lpm and 0.2 V/lpm for the 25- and 50-turns per pole stators, respectively. The integration of all device components will lead to a compact and low-cost spirometer for patient self-monitoring.

Electrostatic neutralization characteristics of an ac-corona-discharge-type ionizer in mixed N2-O2, N2-SF6 atmosphere

引用

IEEJ Transactions on Fundamentals and Materials 2016年第1期136卷 33-40页

作者： Nemoto, Daisuke Kristanto, Yudi He, Wanting Matsuo, Takeshi Sato, Naoyuki Okano, Kazuo Ikehata, Takashi Institute of Applied Beam Science Graduate School of Science and Engineering Ibaraki University 4-12-1 Nakanarusawa Hitachi316-8511 Japan Department of Electrical Engineering Polytechnic University 2-32-1 Ogawanishi Kodaira187-0035 Japan

We are developing an electrostatic neutralizer operating in an atmosphere without oxygen for the organic electronics fabrication industry. As a part of the study, we investigated ion generation and neutralization characteristics of an ac-corona-discharge-type ionizer in different atmospheric gases such as ambient air, pure nitrogen, mixed N2-O2 and N2-SF6 gases, with changing the partial pressure of O2 and SF6, respectively. The I-V characteristic of the emitter shows that the negative current in nitrogen gas is significantly greater than the positive one;thus the product final voltage VPF gives a significant deviation to a negative value (about -2 kV). However, by introducing SF6 gas by 0.01 %, VPF reduces to about 0 V as that in ambient air. The amount of SF6 needed to improve the ion balance is three orders of magnitude smaller than that of O2, due to higher electronic affinity that a SF6 molecule has.

ALICE is a large experiment at the CERN Large Hadron Collider. Located 52 meters underground, its detectors are suitable to measure muons produced by cosmic-ray interactions in the atmosphere. In this paper, the studies of the cosmic muons registered by ALICE during Run 2 (2015–2018) are described. The analysis is limited to multimuon events defined as events with more than four detected muons (N_µ > 4) and in the zenith angle range 0^◦ < θ < 50^◦. The results are compared with Monte Carlo simulations using three of the main hadronic interaction models describing the air shower development in the atmosphere: QGSJET-II-04, EPOS-LHC, and SIBYLL 2.3d. The interval of the primary cosmic-ray energy involved in the measured muon multiplicity distribution is about 4×10¹⁵ < E_prim < 6×10¹⁶ eV. In this interval none of the three models is able to describe precisely the trend of the composition of cosmic rays as the energy increases. However, QGSJET-II-04 is found to be the only model capable of reproducing reasonably well the muon multiplicity distribution, assuming a heavy composition of the primary cosmic rays over the whole energy range, while SIBYLL 2.3d and EPOS-LHC underpredict the number of muons in a large interval of multiplicity by more than 20% and 30%, respectively. The rate of high muon multiplicity events (N_µ > 100) obtained with QGSJET-II-04 and SIBYLL 2.3d is compatible with the data, while EPOS-LHC produces a significantly lower rate (55% of the measured rate). For both QGSJET-II-04 and SIBYLL 2.3d, the rate is close to the data when the composition is assumed to be dominated by heavy elements, an outcome compatible with the average energy E_prim ∼ 10¹⁷ eV of these events. This result places significant constraints on more exotic production mechanisms. © 2025 The Author(s).

The first measurements of proton emission accompanied by neutron emission in the electromagnetic dissociation (EMD) of Pb208 nuclei in the ALICE experiment at the Large Hadron Collider are presented. The EMD protons and neutrons emitted at very forward rapidities are detected by the proton and neutron zero degree calorimeters of the ALICE experiment. The emission cross sections of zero, one, two, and three protons accompanied by at least one neutron were measured in ultraperipheral Pb208−Pb208 collisions at a center-of-mass energy per nucleon pair sNN=5.02TeV. The 0p and 3p cross sections are described by the RELDIS model within their measurement uncertainties, while the 1p and 2p cross sections are underestimated by the model by 17–25%. According to this model, these 0p, 1p, 2p, and 3p cross sections are associated, respectively, with the production of various isotopes of Pb, Tl, Hg, and Au in the EMD of Pb208. The cross sections of the emission of a single proton accompanied by the emission of one, two, or three neutrons in EMD were also measured. The data are significantly overestimated by the RELDIS model, which predicts that the (1p,1n), (1p,2n), and (1p,3n) cross sections are very similar to the cross sections for the production of the thallium isotopes Tl206,205,204.

Full range of motion (ROM) at a joint is necessary for efficient and adaptive movement; as such, it is an essential clinical evaluation measure for assessing an individual's motor function, which can be affected by any number of musculoskeletal injuries and neuropathies. Measurement of joint ROM in the clinic has classically been accomplished statically through the use of a manual goniometer. More recent efforts in the fields of prosthetics and orthotics have demonstrated the potential utility of wearable systems (e.g., exoskeletons, orthoses) designed to control joint motion(s) and instrumented with sensors capable of capturing joint angle data dynamically. This paper presents a novel methodology to assess the performance of a variety of angle sensors in the context of wearable joint angle measurement, particularly for use in articulated ankle-foot orthoses (AFOs). Dynamic and static errors are considered, and a cost-benefit analysis of a variety of off-the-shelf and custom-built sensors is reported to provide comparative data for selecting a sensor to measure joint motion in wearable exoskeletal systems. All of the sensors considered reported angular errors below 5° across all tests, though the optical encoder consistently demonstrated the highest accuracy (

Nowadays, messaging technology in digital data form more often used and not less messages that confidentially wanted. Then it should be modified so that can be understood only by the sender and the intended recipients. All of this system can be realization by using cryptography. LUC algorithms are introduced by Smith and Lennon in 1993. LUC algorithm is an algorithm that based on the use of Lucas sequence (specific arithmetic operations derived from Lucas row) that rarely used to enhance the security of the messages. In this research, LUC algorithm is combined with visual cryptography to process the encryption and the description of a colored image. Four different images were used in the trial here. The performance of the system is assessed using Structural similarity (SSIM) which has an assessment similar to human eye. If the image quality is the same as the original image, then the SSIM value is one. Whereas if the quality of decryption image is very different from the original image then the value of SSIM is zero.
