U-healthcare industry has appeared and developed rapidly due to the development of the telecommunication and Health care technology, the increase of the needs of the Health care providers, and increment of the demands of the Health care users. The core factor of the U-Healthcare fields is the monitoring technique for the patients. In this paper, designed the system which was composed of power line communication (PLC) device and a telemetry intravenous (IV) drip monitoring device were proposed. An additional LAN network formation is not needed for data communication by using PLC and we were able to reduce the costs by using already formed power grid. In addition, the wireless capacitive sensor was used to detect the remaining amount of IV set, and microcontroller was used to transmit the results by using RF communications. According to the experiment results, using the power line for long distance communication is able to achieve the U-healthcare effect.

As far as we know, there is not a Node Localization Algorithm (NLA) that presents the same accuracy for all possible scenarios. We believe that a NLA should be able to "interpret" the dynamic information of the environment. In this sense, simple NLAs are rather focused and might perform well for specific scenarios and applications. Therefore, information fusion and context awareness seems to be an appropriate approach to address this issue. We propose the Smart Environmental Architecture for Node Localization (SEA-NL), which is composed by two main elements: (i) the Smart Beacon Nodes (SBNs) and (ii) the Logical Position of Nodes (LPN). In (i) the obstruction level indicator is estimated and can improve the estimation of distances among nodes. In (ii) environment information and a one to one relation between a node and an object are used and can also improve location estimation. Via simulation, our architecture was tested indoors and outdoors considering three localization algorithms: the Weighed Centroid Localization (WCL), the Centroid Localization, and the Triangular Centroid Localization. Finally, we present an accuracy comparison among NLAs used in isolated way, and by using the SBNs, the LPN, and the SEA-NL, where our architecture improves WCL up to ~30.88%.

This paper presents a pioneering approach for weld bead detection in radiographic images obtained by the Double Wall Double Image (DWDI) technique. Such task constitutes an essential step for several high level processes, such as fully automatic flaw identification on welded joints. Sets of sample pixels, corresponding to candidate solutions provided by a genetic algorithm (GA), are compared to pre-defined synthetic weld bead and pipe models in an image matching procedure. The fitness of each set (individual) is evaluated based on a linear combination of its genotype (evaluated by a heuristic function) and phenotype. The evolutionary process automatically selects the best individual in the population and, thus, provides information such as position, orientation and dimension of the detected object. The proposed approach successfully detects pipes and weld beads in radiographic images of different complexities, encouraging future works.

A microphone implanted under the skin became a significant issue owing to the advent of fully-implantable hearing aids (F-IHAs). And, the design of implantable microphone is needed to be considered the biocompatibility, effects of the human skin and directivity. However, there were few studies to develop implantable microphone to consider directivity. In this paper, to design and implement the implantable microphone for the F-IHA, the directivity of the implantable microphone placed under an artificial skin model was measured. The artificial skin used the test model was made by a gelatin gel that was normally studied as soft tissue model of an ultra-sound phantom. And acoustic properties of the test model skin are similar to it of rats that are the transmission loss and the absorption coefficient.

A new implantable hearing device, which vibrates round window (RW) of human cochlea, has been widely developed in the world. This device has been remarkable owing to compensate conductive hearing loss of hearing impaired people which was damaged their ossicles. Recently, piezoelectric actuator has been applied to RW drive type hearing devices because of flat and excellent vibrational characteristics at audible frequency range. However, in case of the RW vibration, patients cannot hear natural sound because the auditory pathway don't include middle ear. And human middle ear has resonant characteristics. Thus, piezoelectric vibrators need the resonance corresponding to the middle ear characteristics for hearing natural sound.

This study proposes a new wireless skin moisture detection system using a capacitive sensor rather than traditional optical methods. Moisture is the most important factor for maintaining healthy skin. The moisture in the skin can be detected by a capacitive sensor. The aim of this study was to design a wireless capacitive senor skin moisture detection system. The capacitive sensor was pressed onto the skin of a rat to measure the moisture, and the data was transmitted with the RF method. The transmitter and receiver were individually controlled by a microprocessor. The results of the preliminary experiment show that using a capacitive sensor to detect skin moisture was possible. In addition, the wireless detection system showed a good performance in an in-vivo experiment.

This paper evaluates existing taxonomies aimed at characterizing the interaction between robots and their users and modifies them for health care applications. The modifications are based on existing robot technologies and user acceptance of robotics. Characterization of the user, or in this case the patient, is a primary focus of the paper, as they present a unique new role as robot users. While therapeutic and monitoring-related applications for robots are still relatively uncommon, we believe they will begin to grow and thus it isimportant that the spurring relationship between robot and patient is well understood.
