As the aging of the population aggravates, the problem of fall has aroused more attention. We have proposed a novel pre-impact fall detection algorithm and protection system. The real-time algorithm used the thresholds of vertical velocity and displacement profile to detect fall events in switching periods of fast motion. It can effectively solve the problem of false alarms of jump and jogging for daily-life applications. A second-order lag filtering algorithm method was utilized to reduce the drift of the vertical velocity with good performance. In addition, the vertical displacement profile was calculated by using the vertical velocity estimation. The algorithm got 93.6% sensitivity and 95.6% specificity, which was higher than the algorithm without displacement with 75.6% specificity. The results demonstrated the effectiveness of the proposed detection method, which were evaluated by subjects wearing fall detection and airbag system.

The paper presents the mechatronic system for solar energy acquisition for using the system fed on. The mechatronic system with two independent movements affords the high accuracy positioning along the two axes for an optic beam narrowing having the main role of focusing the solar energy. The mathematical model and the design of its components are made by using Delphi. The control of mechatronic system with movements along the two axes, which are azimuth and elevation, has been done with microcontroller. © 2017, Cefin Publishing House. All rights reserved.

FES has been applied for movement restoration, rehabilitation and therapy in spinal cord injury and nervous system failure subjects, whose number rise worldwide every year. Despite the increase, assist devices that are expected to aid healthcare delivery are not in abundance and could be as a result of standards imposed due to the sensitive condition of the subjects. Although closed loop control systems are expected to positively aid in that regards, the delicacy of the plant was a big constraint. An existing model from the works Ferrarin and Pedotti was elaborated from the knee swinging to the sit-to-stand movements and from the two mathematical models it can be inferred that even though similar higher level of excitation would be required for sit-to-stand manoeuvre. As part of research to improve on closed approach for the FES system, an appraisal was successfully done on the neuromuscular model together with fatigue models from the works on Lynch. The remodelled fatigue models to suit the research were presented.

Open Materials Science Journal 2016年 10卷 29-36页

作者： Zheng, Chun-Yi Chiang, Wen-Jung Lai, Yeong-Lin Chang, Edward Y. Chen, Shen-Li Wang, K.B. Department of Mechatronics Engineering National Changhua University of Education Changhua50007 Taiwan Mechatronic Integration and System Control Research Center National Changhua University of Education Changhua50007 Taiwan Department of Materials Science and Engineering National Chiao Tung University Hsinchu30010 Taiwan Department of Electronic Engineering National United University Miaoli36063 Taiwan

GaAs power metal-semiconductor field-effect transistors (MESFETs) were fabricated using direct double silicon (Si) ion implantation technology for wireless communication applications. A 150-μm MESFET had a saturation drain current of 238 mA/mm after Si3N4passivation. A 15-mm MESFET, when measured under a class-AB condition with a biased drain voltage of 3.4 V and a quiescent drain current of 600 mA, delivered a maximum output power (Pout) of 31.1 dBm and a maximum power-added efficiency (PAE) of 58.0% at a frequency of 1.88 GHz. The MESFET exhibited a Poutof 29.2 dBm with a PAE of 45.0% at the 1-dB gain compression point. The MESFET, when measured under a deep class-B condition with a biased drain voltage of 4.7 V and a quiescent drain current of 50 mA, achieved a maximum Poutof 33.1 dBm and a maximum PAE of 55.9% at 1.88 GHz. The MESFET operating at 4.7 V and 1.88 GHz exhibited a P1dBof 31.8 dBm and an associated PAE of 47.1% at the 1-dB gain compression point. When tested by IS-95 code-division multiple access (CDMA) standard signals and biased at 4.7 V under the deep class-B condition, the MESFET with a Poutof 28 dBm demonstrated an adjacent channel power rejection (ACPR) of –31.2 dBc at +1.25 MHz apart from the 1.88 GHz center frequency and –45.7 dBc at +2.25 MHz. © Lai et al.

Tower crane is also known as rotary crane and widely used in constructions due to limited human capability to carry the various types of load at the construction site. In general crane is used for the purpose of loading and unloading heavy material from one place to another. However, in order to transfer the material in minimum time from one location to another, swaying of the payload will occur. Hence, this research presents the investigation of tower crane system which mainly focusing on the swaying angle of the payload by implementing conventional and intelligent controllers. Its mathematical modeling is developed using the Newton’s Second Law and simulation is done within the MATLAB/Simulink environment. Simulation results are presented in cart trajectory capability and payload sway angle reduction. A comparative assessment between conventional controller and intelligent controller for the tower crane system are presented and discussed. Furthermore, the effect of various rope length and payload mass of the tower crane system to the performance of trajectory capability and sway angle reduction are also presented and discussed.

This paper presents relevant aspects of the idea of using the digital medicine in cancer, so that to shape a viable strategy for creating and implementing an interactive digital platform, NEO-VIP, that should be the basic support to design the strategy for integration of basic, clinical and environmental research on neoplasia progression to cancer. The two main components of the VIPRO Platform are represented by the workstation 'engineering Station' for CPS (Cyber Physical System) and 'omics' technology and by the 'Graphical Station' for the development of a virtual mechatronic system environment and virtual reality for system components' motion. The NEO-VIP Platform will consolidate the collaboration of specialized institutions in IT, medicine, health, life standards so that to enhance their capabilities to work as a consortium. The results lead to the possibility developing NEO-VIP Platform in the IT modelling field, applied on bio-medical data, as a new player alongside with the existing ones. So, new improved methodologies for investigating social implications of machines working with and for people will be applied. © 2016 IEEE.

In situ nanomanipulation system is presented with 3D scanning electron microscope - computed tomography (SEM-CT) system integrated with inside an environmental - SEM (E-SEM). The E-SEM was used to achieve a real-time high resolution imaging for high precision nanomanipulation. The SEM-CT system was used for obtaining 3D cross-sectional image with sub-micron high resolution. In this paper, Caenorhabditis elegans (C. elegans) was used as a target of biological sample to demonstrate a nanoinjection operation. The nanoinjection was determined by the SEM-CT system with its 3D information. © 2015 IEEE.

This study presents the survival microinjection into Caenorhabditis elegans (C. elegans) with in vivo observation based on micromanipulation. The microinjections were achieved with micro-gel beads which are enable to encapsulate chemicals for injection. In this study, a fluorescent material was used to evaluate the injection positional precision inside the C. elegans. The fluorescent microbead was picked up at the tip of a micropipette injection tool and injected by a piezo actuated microinjector. The distance between the injected micro-gel bead and closest nerve axon was measured as 20.3 μm and 16.5 μm by in vivo observation of a confocal microscopy. The two types of pipette tools were used to evaluate the success and survival rates of microinjection, and the smaller pipette (pipette A, 0.8 μm in diameter) showed higher rates as 50 % and 67 % respectively. © 2015 IEEE.
