Textiles, in combination with advances in materials and design, offer exciting new possibilities for human and environmental interaction, including biometric and touch-based sensing. Previous fabric-based or flexible touch sensors have generally required a large number of sensing electrodes positioned in a dense XY grid configuration and a multitude of wires. This paper investigates the design and manufacturing of a planar (two-dimensional, XY location) touch fabric sensor with only two electrodes (wires) to sense both planar touch and pressure, making it ideal for applications with limited space/complexity for wiring. The proposed knitted structure incorporates a supplementary method of sensing to detect human touch on the fabric surface, which offers advantages over previous methods of touch localization through an efficient use of wire connections and sensing materials. This structure is easily manufactured as a single component utilizing flatbed knitting techniques and electrically conductive yarns. The design requires no embedded electronics or solid components in the fabric, which allows the sensor to be flexible and resilient. This paper discusses the design, fabrication, sensing methods, and applications of the fabric sensor in robotics and human-machine interaction, smart garments, and wearables, as well as the highly transdisciplinary approach pursued in developing medical textiles and flexible embedded sensors.

Novel occlusion object removal with inter-frame editing and texture synthesis

Journal of Information Hiding and Multimedia Signal Processing 2016年第2期7卷 386-398页

作者： Qin, Chuan Ren, Hao Ran Chang, Chin-Chen Chen, Qing Kui School of Optical-Electrical and Computer Engineering University of Shanghai for Science and Technology Shanghai200093 China Shenzhen Key Laboratory of Media Security Shenzhen University Shenzhen518060 China Department of Information Engineering and Computer Science Feng Chia University Taichung40724 Taiwan

In this paper, an effective occlusion object removal scheme based on inter- frame editing and texture synthesis is proposed, which can be used to realize the seamless filling for the undesired objects during taking photograph. The principle idea of the proposed scheme is to fully taking advantage of the information of recorded frames during the preparing time before pressing the shutter. First, by inter-frame editing, the moving region can be detected and extracted with the frame difference and OR operation. Since the desired foreground object is often stationary, thus, the extracted moving region, i.e., the undesired moving object, can be basically filled with the inter-frame information. The post-processing consisting of the inter-frame and intra-frame texture synthesis can be further utilized to remove residual moving region and undesired stationary object, respectively. Experimental results demonstrate the effectiveness of the proposed scheme. © 2016.

International Journal of Smart Home 2016年第11期10卷 95-108页

Human activity recognition is a main research area of context-aware computing, and is widely used in many applications, such as smart home and elderly care. Smartphonebased human activity recognition is very popular by making use of the embedded inertial sensors. However, there exists the problems of misclassification activities, and how to effectively apply the model trained by known users to new users. To solve these two problems, in this paper, we proposed a novel approach, Uncertainty Sampling based posterior Probability Extreme Learning Machine (USP-ELM), by introducing two strategies: First, we transfer the actual outputs of ELM to posterior probabilities for each instances, and then use uncertainty sampling strategy for confidence level assignment to adapt the training model and improve the classification accuracy. Experimental results show that the proposed approach is more efficient, compared with the existing ELMs. © 2016 SERSC.

Despite substantial declines since 2000, lower respiratory infections (LRIs), diarrhoeal diseases, and malaria remain among the leading causes of nonfatal and fatal disease burden for children under 5 years of age (under 5), primarily in sub-Saharan Africa (SSA). The spatial burden of each of these diseases has been estimated subnationally across SSA, yet no prior analyses have examined the pattern of their combined burden. Here we synthesise subnational estimates of the burden of LRIs, diarrhoea, and malaria in children under-5 from 2000 to 2017 for 43 sub-Saharan countries. Some units faced a relatively equal burden from each of the three diseases, while others had one or two dominant sources of unit-level burden, with no consistent pattern geographically across the entire subcontinent. Using a subnational counterfactual analysis, we show that nearly 300 million DALYs could have been averted since 2000 by raising all units to their national average. Our findings are directly relevant for decision-makers in determining which and targeting where the most appropriate interventions are for increasing child survival. © 2022, The Author(s).

A vibration isolation system called Type-Bp system used for power recycling mirrors has been developed for KAGRA, the interferometric gravitational-wave observatory in Japan. A suspension of the Type-Bp system passively isolates an optic from seismic vibration using three main pendulum stages equipped with two vertical vibration isolation systems. A compact reaction mass around each of the main stages allows for achieving sufficient damping performance with a simple feedback as well as vibration isolation ratio. Three Type-Bp systems were installed in KAGRA, and were proved to satisfy the requirements on the damping performance, and also on estimated residual displacement of the optics.

AIP Conference Proceedings 2017年第1期1806卷

Inan 1School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA 30308 USA 2Interactive Media Technology Center Georgia Institute of Technology Atlanta GA 30308 USA 3Wallace H. Coulter Department of Biomedical Engineering Georgia Institute of Technology Atlanta GA 30308 USA

We have developed a novel, wearable sensing system based on miniature piezoelectric contact microphones for measuring the acoustical emissions from the knee during movement. The system consists of two contact microphones, positioned on the medial and lateral sides of the patella, connected to custom, analog pre-amplifier circuits and a microcontroller for digitization and data storage on a secure digital card. Tn addition to the acoustical sensing, the system includes two integrated inertial measurement sensors including accelerometer and gyroscope modalities to enable joint angle calculations; these sensors, with digital outputs, are connected directly to the same microcontroller. The system provides low noise, accurate joint acoustical emission and angle measurements in a wearable form factor and has several hours of battery life.

Wood represents a form of renewable energy that is widely available. In rural Mexico it represents the main source of energy. It is used not only for cooking, but also to heat houses, and to provide lighting. Most Mexican villagers use wood via stoves, however these appliances usually bring health hazards and are harmful for the environment. Due to these problems new technologies, such as efficient stoves, have been implemented to bring better combustion, reduce amount of smoke, and overall make the transfer of heat more efficient. However, the social adoption of efficient stoves is non-trivial. Our study shows how making efficient stoves follow the guidelines of appropriate technology, we can: 1) successfully understand the cultural and social aspects of how villagers use renewable energy;2) design technology that by considering a region's traditions, is used long term.

The generation of a wide-range THz wave is investigated from a photoconductive antenna excited using a chaotic oscillation multimode semiconductor laser with optical delayed feedback by an external mirror. The stable THz wave is obtained from the multimode-laser diode excited photoconductive antenna by using a laser chaos. For a high sensitive detection, a metal V-grooved waveguide (MVG) is also used. As the MVG gap is narrower from 200 to 20[μm], the detected signal is increased about twice.
