    Recently, a variety of user interfaces are used to control various electrical appliances and equipments. Almost all devices equipped push-button or touch panel so that they can be operated by using finger easily. These interfaces are very useful and convenient, but still they have some drawbacks such as the fixed size, the squared shape, and the flat surface. Due to these restrictions, it is hard to add or to remove buttons when the number of commands is altered. To solve the above problems, we propose a new type of touch panel switch. Proposed panel can be stuck on an arbitrary bended surface, and be cut to arbitrary shape. Moreover the number of switch for one device controlling can be easily altered. Thus, it can be placed at various target objects existing in human living space. For examples, table, desk, chair, doll, handle of vehicle, pillow, and people's bodies etc. The method, experiments, and the results are explained in this paper. The demonstration shows the effect of proposed touch switch. View full abstract»

    Space Scale, a design of the body mass measurement device (BMMD), was proposed to obtain a lightweight instrument with sufficient accuracy. The main feature of the proposed instrument is the use of a bungee cord that generates a moderate but steady force and a very large displacement during the measurement. Its prime feature is the simple structure of the instrument. The second is a minimal effect from change in subject posture, i.e. the change in density distribution of the subject astronaut. The present status and the future prospects of the Space Scale, including the results of the experiments using the airplane (parabolic flight experiment) and the International Space Station (ISS), are reviewed.

    Software engineering is very different from the other fields of engineering. One of the difference points is that the authors of software products make software products public on the Internet so that anyone can use them without charge. Such software products are called free software or open source software. However, free software or open source software cannot make money and it is not software business aside from that it is good or bad. This paper discusses how to make business for software products which are made by individuals or small organizations. This discuss shows some reasons why such software products cannot be commercial software products which can make money. View full abstract»

  • Novel measurement method for physical activity based on electrostatic induction technique

    Page(s): 29 - 34
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (853 KB) |  | HTML iconHTML  

    We here present a novel method for measuring human physical activity, which is based on detecting the electrostatic induction current generated by the walking motion under non-contact and non-attached conditions. This method involves measuring the electrostatic induction current flowing through a measurement electrode. A theoretical model for the electrostatic induction current generated because of a change in the electric potential of the human body is also proposed. By comparing the numerical integration value of the electrostatic induction current with the plantar surface area, it becomes obvious that this model effectively explains the behavior of the waveform of the electrostatic induction current flowing through the electrode. The normal walking motions of daily living are recorded using three measurement electrodes located in an ordinary house. The obtained results show that detailed information regarding physical activity such as a walking cycle can be estimated using our proposed technique. This suggests that the proposed technique, which is based on the detection of the walking signal, can be successfully applied to the estimation of human physical activity. View full abstract»

    Page(s): 412
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (21 KB)  

    The need for highly performing vascular biomaterials is rapidly increasing with the ageing of population. Vascular diseases are the primary cause of death in the world and at least 1 million patients undergo to surgical operation for prosthesis implantation each year worldwide to face cardiovascular occlusive diseases, aneurysms and acute renal failures. As the major problem still resides in an interfacial mismatch between the synthetic inert graft and the natural living tissue surrounding it, the common approaches consist of modulating the tissue/biomaterial interface by modifying the synthetic graft surface properties, in an attempt to improve their long-term biocompatibility and hemocompatibility. Thus, several coating techniques, including plasma-based treatments, were investigated during the last 20 years to improve clinical performances of cardiovascular devices, including stents and vascular prostheses. Strong binding of selected bio-molecules, including protein-repellent ones, surface patterning, and a number of other strategies has already been investigated in order to obtain biological-like surfaces based on the hypothesis that the human body would positively interact with these biological coated materials. Nevertheless, such coatings did not completely successes clinically as it turned out that the bioactive materials could not play their biological role as well as expected and eventually led to the development of negative interactions and finally to clinical complications. Today, nanotechnology and surface modifications provides a new insight to the current problem of biomaterial failures, and even allows us to envisage strategies for the organ shortage. Advanced tools and new paths towards the development of functional solutions for cardiovascular clinical applications are now available. Within this general framework, this talk will focus on highly-adherent and strongly-cohesive (after deployment) fluorocarbon nano-coatings for intravascular stents, bi- -mimicking coatings for vascular prostheses, and degradable metals for temporary devices. The intrinsic goal is to present an extremely personal look at how materials and surface modifications have progressed, from the glory days of their introduction, to the promising future that nanotechnology may or may not hold for improving the quality of the life of millions worldwide.

    Page(s): 414
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (18 KB)  

    Telehealth allows health care professionals to diagnose and treat patients in remote locations using telecommunication technology. In few developed countries, telehealth has become standard medical practice. Over 10,000 peer review papers have been published during past 20 years supporting the clinical effectiveness and cost savings of telehealth. Unfortunately, telehealth has not been implemented widely especially in developing countries yet. In order to identify the resistance and enabling factors for the implementation of telehealth especially in developing countries, a comprehensive study has been done. This includes communication and application technologies, standard and legal issues, cost and business models, as well as user and key player requirements. The study result shows that technology has become an important enabling factor. Some technologies even have fulfilled the critical requirements such as reliability, user friendliness, simplicity, safety, security, cost effectiveness, connectivity and compatibility. However, without solving related legal issues, implementation of an excellence business model as well as user acceptance, telehealth will be difficult to be implemented in developing countries. A telehealth model with considering those resistances and enabling factors has been developed and will be presented in this conference. The model has been tested in some hospitals and clinics in few developing countries. Test result shows that the model is suitable, cost effective and able to improve the health service quality in developing countries. It is hoped that the developed model can be widely implemented in the near future. This will benefit people in rural areas, developing countries, correction facilities (prison and rehabilitation centre), schools, mobile units, disaster areas, and industrial units (mines).

    Testing is crucial in software development. Continuous researches being done to discover effective approaches in testing that capable to detect faults despite of reducing cost. Previous work in State-Sensitivity Partitioning (SSP) technique, which based on all-transition coverage criterion, has been introduced to avoid exhaustively testing the entire data states of a module by partitioning it based on state's sensitivity towards events, conditions and action. The test data for that particular module testing is in form of event sequences (or test sequence) and sets of test sequences in test cases will perform SSP test suite. The problem occurs in SSP test suite is data state redundancy that leads towards suite growth. This paper aims to discuss an initial step of our ongoing research in enhancing prior SSP test suite. Our work will try to find out the best way in removing redundant data state in order to minimize the suite size but yet capable to detect faults introduced by five selective mutation operators effectively as the original suite.

    The automatic car steering technology has the potential to reduce the rate of traffic accidents, in the future. As a starting point, in this research a mobile robot, which can run between two road lines using a camera is designed. To detect the road lines in the image from the camera, Edge Detection and Line Detection method is used. The kernel used in the Edge Detection method is the Sobel kernel. The Line Detection is done by finding the coordinates of the maximum value for each column in the Edge Detection's image result. The intersection of two lines will show a certain direction of the robot to correct its direction of movement. Both methods are implemented on a wheeled mobile robot that is controlled by a microcontroller. The robot can detect the miniature road lines and correct its direction of movement so that it can run between the two road lines in parallel with the lines. View full abstract»

    Entropy is defined as a measure of how much information can be retrieved from a message or information sources. In data communications, entropy from information sources is described in the form of bits and closely related to the probability of arriving message to receiver and depends on the period of light spectrum, therefore information source rates affected. The problem faced is how to describe it in visual form. Here the entropy simulation was programmed by using Matlab GUI. The design of entropy simulation program consists of two types. The first type is entropy simulation program of text information as input. The second type is entropy simulation program of voice information as input. The results of both simulation program show that entropy value influenced information source rates. In other words, information source rates will increase with the increasing of entropy value.

    This paper discus an ASIC implementation of puncture and SSP for MIMO IEEE 802.11n 4×4 MIMO Wireless LAN system. We also describe its receiver counterpart block, which is SSDP and Depuncture. The biggest challenge of this work is 72 modes operation that need to be supported. The design is implemented on 90nm ASIC CMOS technology. Synthesis result for puncture and SSP reveal that the logic area is 0.025 mm2. The correspond gates count is 4.535 KGE. Circuit power consumption is 0.736 mW. The design can work at very high frequency up to 1000MHz (1GHz). Thus, it could be implemented for very high data rate applications that use MIMO OFDM techniques up to 3,750 Mbps, such as digital cinema and HDTV over wireless transmission. Meanwhile, SSDP and Depuncture synthesis shows that the logic area is 0.0309 mm2 which is equivalent with 5.581 gates. The maximum operating frequency is lower than its transmitter counterparts, only 250 MHz. Circuit power consumption is 0.209 mW. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (714 KB) |  | HTML iconHTML  

    Communication between the near field communication (NFC) devices occurs in a very close distance of less than 10 cm. In the NFC-based payment system, close proximity between devices will increase the security of transactions. The disadvantage is the interaction between devices requires more physical activity of device owners because the device must be brought near to other devices some times. Besides requiring more physical activity, NFC-based interaction also takes a longer time because the device needs to be moved from one position to another. This paper proposed Secure and efficient protocol that will reduce the physical activity of the device owners and reducing transaction time. The data sending between merchant and payer will be executed without waiting for each other and one transaction will require two data transmissions are performed by the merchant and payer. Transactions are secured by the use of encryption on each data which sent by the merchant and payer. In addition, the protocol also guarantees the security of offline micro transactions and online macros transactions. View full abstract»

    Regular maintenance of highway is an important issue to ensure safety of the vehicles using the road. Most of existing method of highway inspections are destructive, which take much times, efforts, and costs. In this paper, we propose GPR (Ground Penetrating Radar) imaging to detect possible defect of the road. GPR scanning on a plane parallel to the road yields 3D images, so that slice-by-slice images can be generated for a comprehensive evaluation. First, we simulate the subsurface-scanning with GPR-Max software, by setting up the parameters similar to expected real-condition. Then, we set up the experiment in our GPR Test-Range, in which a Network Analyzer is employed as a GPR. We compare and analyze both of the simulation and Test-Range results, including slice analysis, to asses the quality of the method. Our results indicates implementability of such 3D GPR imaging for road inspection. View full abstract»
