Abstract
Mobile learning has long been identified as one of the natural directions in which CALL is expected to move, and as smaller portable technologies become less expensive, lighter and more powerful, they have the potential to become a more integral part of language learning courses as opposed to the more supplemental role often assigned to computer labs. Mobile phones have been the topic of a number of recent studies, including for learning pragmatic phrases via mobile email, and as electronic flash cards. With the development of mobile systems that can access the Internet, more sophisticated applications which allow the use of databases and interactive web content have been made possible. The current study describes one such application, investigating the use of a prototype mobile-based intelligent vocabulary tutor system by learners in an advanced EFL class. Learners used the tutor to complete vocabulary activities in a variety of task formats through either their mobile phone or through a computer, and the system kept logs of all access to the system. A profile of each learner was created in terms of the vocabulary that they had difficulty with, and presented these items to the learners more frequently than items that were less likely to cause learners problems. Learner access logs to the vocabulary activities and the learner profiles were analysed, and a survey was administered to learners at the completion of the project. The results are discussed in terms of learner usage patterns and learner perspectives regarding each platform.

Flexible printed circuit (FPC) boards have the characteristics of being easy to turn, small mass, thin thickness and so on. They have been widely applied in consumer electronics such as mobile phones, notebook computers, digital television, video cameras, etc. (Zhang et al., 2005). The reason why FPC boards have obtained wide application is that they have special properties when compared with other materials. FPCs are a kind of special circuit board originally designed for enhancing the rate of space utilization. They can satisfy both micro- and high-complexity technical requirements, while also reducing the assembly process. As the first choice of producing microminiaturization electronic and mobile electronic products, they can also have good heat dissipation capabilities and find an important position in electronic products, such as notebook computers, mobile phones and so on. Recently, the production lines of FPC boards have required sampling pictures in movement and detecting product defects, thus inspecting product deficiency has become an important link in the production process. Nowadays, domestic product testing is mostly human visual inspection with high labor intensity. Low accuracy is caused by personal subjective judgment.

It can be at most no base station signal area to achieve the call, while the body drop proof and waterproof, can also be used in a minimum of minus 20 degrees Celsius, the highest 50 degrees above zero the harsh environment, the usability is very strong. It can also withstand severe temperature changes and powerful impact.
The machine is also equipped with a wide variety of sensors that can intelligently detect weather conditions such as air pressure, compass and temperature at the current position of the engine owner

As FPC boards have been widely applied in recent years, the domestic research about its defects is still preliminary, with most test methods being introduced from abroad, or derived from more general test methods used for inspecting PCB boards. The CAD/CAM Research Institution of Central South University has studied defect detecting on the circuit boards of mobile phones (Cao, 2007). They collected pictures through the use of a CMOS camera, and the detection was accomplished through mixing methods. South China University of Technology also studied FPC boards through adopting the DSP visual inspection system (Lu, 2011); they put forward that ADIBlackfin533 type of DSP should be taken as processor kernel and a high-speed line array CCD should be taken as the sensor for inspecting defects. The research center of Xiamen University has applied focus difference into inspecting optical systems (Yuan, 2008). The discontinuous surface optical inspection of differential astigmatism principle is used to inspect FPC boards.

1. Introduction
According to the World Health Organization, in 2015 there will be 1.5 billion overweight adults worldwide, and about one third of them will be obese.2 Obesity significantly increases the risks for developing chronic diseases such as cardiovascular disease, diabetes, and various types of cancer.3 These chronic diseases are the leading causes of disability and death. Accordingly, in today’s society, adhering to a healthy lifestyle is considered of the utmost importance.
Research has shown that a healthy lifestyle can contribute to (i) the prevention of the development of chronic illness, (ii) the prevention of serious complications that follow from this development, and (iii) the improvement of the quality of life of people who have developed a chronic illness. It is therefore that therapy for chronic patients often consists of healthy lifestyle regulations, including a healthy diet and a regular exercise regime, aside from medication intake. For many people, however, adhering to a healthy lifestyle requires behavioral changes. Even whilst knowing the benefits of a healthy lifestyle, people find it hard to find (and keep) the optimal balance between work, social life and a healthy diet or medicine schedule. Physical discomforts and side effects of medicine intake are additional barriers for committing to healthy behavior. In short, people have many reasons why they do not do what’s good for them. As a consequence, the number of people that are obese or have a chronic disease has increased considerably over the past years, and the prevalence and costs of interventions addressing the chronic disease burden is expected to rise.

What Type of PCB Substrate Material Is Right for Your PCB? Part Two

In the previous article, substrate material requirement catering to high density and fine lines, high frequency and high speed is discussed. However, this article will continue to provide substrate material requirement catering to high heat resistance and dissipation and rigid PCBs.
Requirement Catering to High Heat Resistance and Dissipation

Market Trends in Flex PCB
According to the Global Industry Analysts Inc., the projection for Flex PCBs in the global market is pointing towards US$15.2 billion by 2020. Several factors are contributing to this trend. Chief among these are the emergence of wearable electronics, polymer plastic solar cells and foldable and rollable smartphones. This has led to an unrelenting focus on the manufacture, performance, and design of special printed circuit boards, mainly of the flexible type. The growth in the market is coming from technological advances in conductive and substrate materials, along with developments in fabrication such as in special copper etching techniques.
Market Areas Driving the Demand
The burgeoning opportunities for flexible electronics are mainly coming from the healthcare sector and are driving the main benefit for growth. With electronic packaging shrinking in size, the need for superior packaging flexibility is driving the interest in flexible PCBs. The growth of disposable electronics is also causing a spurt in the opportunities. Technological advances in flexible ceramics are helping manufacturers shrink the size of substrate materials. The auto end-use sector is helping to drive the demand for flex PCBs as more promising applications are discovered in the areas of haptics and structural electronics.

Intelligent mobile support for therapy adherence and behavior change

High-Quality Graphene Enables Flexible Circuits
Electronics: Researchers use an improved process for making graphene and a new transistor design to build bendable telecommunications circuits that switch at high speeds

Although from the technological point of view, a conventional multilayer PCB still corners a large share of the market, the global trend of shrinking of electronic products is pushing up the requirements for HDI, Rigid-Flex, and Flex technology. The challenge to the manufacturers comes from designing ultra-thin PCBs that must also meet the requirements of signal integrity and EMC specifications while still being low cost.

The paper is structured as follows. First, an overview of approaches for intelligent support systems is provided in Section 2. In Section 3 a model is presented that formalizes the interaction between the different determinants of behavior change. The theoretical framework that provides the foundation of the model is also discussed. An important part of the validation of the system is the validation of the model that is used to reason about the user’s stage of behavior change. These validation studies are described in Section 4. Section 5 demonstrates how the model is integrated in an intelligent system that provides support for individuals with a chronic health condition. In Section 6 the preliminary evaluation of the coaching system based on a pilot study with chronic patients is described. Section 7 concludes with some points for discussion and implications for further research.

With the development trend towards miniature and high function, electronic devices tend to generate larger amount of heat so that thermal administration of electronic devices call for increasingly higher requirement. One of the solutions to this issue lies in the research and development of therinal-enhanced PCBs. Primary condition of PCB performing well in heat resistance and dissipation is the heat resistance and dissipation capacity of substrate. Present improvement in terms of therinal-enhanced capacity of PCBs lies in improvement through resin and filling adding but it only works within a limited category. Typical method is to apply IMS or PCBs with metal core that play a role of a heating component. Compared with traditional radiator and fan, this method leads to advantages of small volume and low cost.

Aluminum is a very attracting material with advantages of rich resources, low cost and excellent heat-conducting property and intensity. Moreover, it is so environment-friendly that it is applied by most metal substrate or metal core. Owing to advantages including economy, reliable electric connection, heat conductivity and high intensity, solder free and lead free, aluminum based circuit board has been applied in consumer goods, automobiles, military goods and aerospace products. There's no doubt on heat-resistance and dissipation property of mental base boards and the key point lies in performance of adhesion between mental board and circuit plane.

To someday develop wearable wireless electronics or smart, bendable medical implants, engineers need flexible integrated circuits that can send and receive telecommunication signals. Such circuits produce these signals by switching on and off rapidly—billions of times per second. Now, researchers in Taiwan have demonstrated they can build circuits made of graphene that switch at speeds of 32 GHz, which are some of the fastest for flexible electronics to date (ACS Nano 2014: DOI: 10.1021/nn5036087). Although the team hasn’t yet made a full wireless device, their circuits show that it should be possible to make a flexible one out of graphene.
The telecommunications circuits inside cell phones and other electronics today are built on rigid silicon chips. To make fully flexible devices, the silicon in these chips needs to be replaced with a flexible material that has good electrical conductivity, such as graphene. It’s a huge materials science challenge, says Po-Wen Chiu, an electrical engineer at National Tsing Hua University, in Taiwan. “It’s very difficult to make integrated circuits on a flexible substrate.”
Chiu’s group made the new circuits by first growing high-quality graphene sheets using a method they had developed over the past seven years. Electrical charges usually move smoothly through graphene, but grain boundaries in the material can disrupt this charge flow. The fewer such defects in the graphene, the faster charges can move, and the faster the resulting circuit will be. Chiu’s group grows their sheets of graphene on copper using chemical vapor deposition. Instead of using a typical continuous flow of hydrocarbon gas to do so, they pulse in hydrocarbon gases every few seconds, which leads to the formation of larger grains and reduces the number of grain boundaries. Then they use an etching process to lift off the graphene and transfer it to a piece of the flexible plastic polyethylene terephthalate.
Another key to their circuits, Chiu says, is the design of their transistors. All transistors consist of four parts: a channel and three electrodes called the source, drain, and gate. The team used their high-quality graphene to make the transistors’ channels.

It has long been believed that the smartphones in our pockets are actually making us dumber; but now there is evidence for it.

The constant presence of a mobile phone has a "brain drain" effect that significantly reduces people's intelligence and attention spans, a study has found.

Researchers at the University of Texas discovered that people are worse at conducting tasks and remembering information if they have a smartphone within eye shot. In two experiments they found phones sitting on a desk or even in a pocket or handbag would distract users and lead to worse test scores even when it was set up not to disturb test subjects.

This research examines both the practicalities and feasibility of using a smart phone in the monitoring of gross daily activity, namely step counts. An Adaptive Step Detection (ASD) algorithm has been proposed and evaluated, based on where the phone is worn on the body. Experiments involved collection of data from a participant who wore two mobile phones (placed at difference positions) while walking on a treadmill at a controlled speed for periods of five minutes. A video recording and pedometer were used to independently record the number of steps in addition to a count by human observation. A step detection calibration factor was determined via a data driven approach, i.e, for each recording, a calibration factor was obtained by learning from two thirds of the acceleration data gleaned from the accelerometer within the smart phone. The remainder of the data was used to test the algorithm. The step counts from the acceleration sensor were validated by the video recordings, which were consistent with the pedometer and human observation. The results show that the step counts detected by the proposed algorithm achieved accuracy of 100% when the mobile phone was placed in the right thigh positions, and achieved above 95% accuracy when the mobile phone was placed in the right breast pocket, bag over right shoulder and right ankle.

Requirement Catering to Rigid PCBs

In modern electronic time, miniature and thinness of electronic devices leads to necessary advent of rigid PCBs and flex/rigid PCBs. Then what type of substrate material is suitable for them? This article will reply.

Increasing application fields of rigid PCBs and flex/rigid PCBs bring about new requirement in terms of number and performance. Polyimide film, for example, can be classified into multiple categories including transparent, white, black and yellow with high heat resistance and low coefficient of thermal expansion in order to be applied in different situations. Similarly, mylar substrate with high cost effectiveness will be accepted by market as well owing to its advantages including high elasticity, size stability, film surface quality, photoelectric coupling and environmental resistance so as to meet the changeable requirement of users.

I sometimes think there are so many mobile applications and services that we have reached a point of information overload. If you were to subscribe to say, twitter/facebook then add in the many services such as travel, weather, stocks and news, it soon becomes apparent that there isn’t any user attention-span remaining for extra or new services.

To make room for new services, I think we might need to start thinking about aggregation of services and more intelligent services. Aggregation is already occurring. Some network operators and phone OEMs are starting to do this (on the idle screen).

Intelligent mobile services are more interesting because they offer some untapped opportunities. In general terms they filter information according to the user’s preferences and context so that less information has to be digested. They may also push (alerts) to the user rather than the user having to waste timing polling (continually checking) for information.

One such idea is Massie Design Studio’s Smart Alarm. It wakes you earlier if you are going to need more time because the weather is bad.

Another idea is to work out where a user is going based on where they are, the current time and their past travel patterns. Mapping this onto locations of travel methods (roads, train, plane, ship) it might be possible to alert the user ahead of time of the timetable or alert them to travel problems. I actually submitted this idea as a feasibility study for the Digital Britain Competition but I unfortunately wasn’t one of the winners.

As FPC boards have already become indispensable products of the electronics industry, there is big difference among their type, production process and winding displacement features; and such detection methods are more complex. Thus, there is a growing need for machine vision to detect the quality of the products. The machine vision (Zongyun, 2012) recognized on the basis of image processing and pattern could be divided into image data acquisition, image preprocessing and defect judgment of three systems. The advantages of machine vision lie in its rapid detecting speed and high inspecting accuracy, which can greatly reduce labor cost and enhance the quality and production efficiency of products. Current research on FPC board defects has already become the focal point of circuit board manufacturers, and creating a set of perfect defect detection systems of FPC board is the imperious demand of manufacturing enterprises.
Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester[1] film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. An alternative approach to flexible electronics suggests various etching techniques to thin down the traditional silicon substrate to few tens of micrometers to gain reasonable flexibility, referred to as flexible silicon (~ 5 mm bending radius)

Section:Previous sectionNext section
2.1 Defect overview of FPC board
According to the requirements of FPC manufacturers, there are several defects which usually appear in the production process of FPC boards. These defects would commonly cause a big influence on the use of an FPC board, and need to be identified, as the manufacturer needs to know more about specific defect types for enhancing product quality. The FPC workflow may cause following defects, including the bareness of coating film pressure, too large separation distance between line conductors, filled air between packet and copper foil in the heave form, the phenomenon of line distortion and kinking, surface scratch and so on. Generally speaking, the defects of an FPC board can be divided into circuit and welding hole defects. Circuit defect includes short circuit, open circuit, too small width of circuit, too big width of circuit and so on. Welding hole defect mainly includes welding hole excursion, tin shortage of welding hole and so on. It is shown as Table I.
