    An open source automation system for controlling electrical appliances using power line communication is presented here. Control messages are sent over Wi-Fi network from a Wi-Fi device to the microcontroller which then couples the messages to the power lines. Ubiquitous power lines are used as physical media to transmit data over 220V/50Hz signal to control appliances/equipment. The data from the microcontroller is coupled onto the power lines using a PLC (Power Line Communication) modem and DCSK (Differential Code Shift Keying) modulation technique is employed to transmit data. Each receiver unit consists of PLC modem plus microcontroller and can be connected anywhere in the power line network. The receivers have addresses assigned to them and only respond to the commands sent to them by the transmitter PLC modem. The receiver unit controls the flow of electricity to the socket. The entire system is devoid of a computer to save power and make it low cost. Use of open source hardware, Power Line Communication and micro-controller collectively reduce the cost of controlling appliances remotely. View full abstract»

    Content discovery has historically been a painful process of repeatedly scanning a large gallery of images or, worse, a textual list of shortened titles. The user experience became a race to see whether the user's thumb or brain got numb first. MEMS and enhanced metadata, combined with better connectivity allow for a navigation experience that is actually enjoyable in its own right. This paper reviews some of the key steps necessary to achieve that. View full abstract»

    Low-interaction honeypots can provide a cost-effective security mechanism for a wide range of computer systems. A central challenge in the development of low-interaction honeypots is the development of emulation programs that mimic the action of server applications on the target platform. The emulation programs must be of high enough fidelity to fool attackers. However, the manual development of these emulations is extremely time-consuming. This paper describes an agent-based optimization system that can automate the generation of emulation programs for honeypots. The system is evaluated in its ability to emulate a mail server. In this evaluation, the system produced correct responses to more than 99% of test data queries. View full abstract»

    De-embedding techniques are frequently applied to signal integrity measurements to remove the unwanted effects of test fixture and thereby isolate the device under test (DUT) performance from the rest of the system. Conventionally, the transfer function (TF) of the channel to be de-embedded could be obtained independently without capturing its interaction to the DUT. However, as data rates increase and channels become more complex, the errors due to discontinuities at the channel to DUT boundary need to be given due consideration. This paper provides simulation and measurement examples to illustrate this effect and proposes a modified approach of generating the channel TF to compensate for those errors. The proposed approach effectively improves the accuracy of the de-embedded result. It can also be used as a validation scheme to correlate the de-embedding accuracy for a given application.

  • A Krawtchouk moments based super resolution technique for multiframe image sequence

    Recently, Xinbo Gau et. al[2] employed Zernike moments to construct a high resolution image sequence from a given set of blurred, down sampled and noisy image sequence. In general, Zernike moments are defined using Zernike polynomials which are not orthogonal over the square image region. Further, these moments are not discrete. Hence, image quality gets distorted due to incorrect moment values. Therefore, to correct these errors, this paper uses Krawchouk moments that posses the following features i) no need for coordinate transformation ii) orthogonal over a square region and iii) they are discrete moments, to create a high resolution image sequence from a given low resolution image sequence. The proposed approach was tested using different multiframe image sequences having small local motion and rotation. Results are compared with Zernike moments, Lanczos and sparse representation methods. View full abstract»

    Using a 50-inch 3DTV and showing four kinds of content, we experimentally evaluated the relationship between TV viewers' emotional states and specific physiological and psychological indices. As statistical analysis, Pearson product-moment correlation coefficient, multiple regression and principal component analysis were performed to estimate emotional state. Our results indicate that near-infrared spectroscopy (NIRS), which represents one aspect of nervous system activities, is a potentially useful index for evaluating the emotional states of “stressed-relaxed” and “feeling of involvement-of boredom.” Moreover, LF/HF and HR are affected by complex emotional states in each subject for evaluating emotional states.

    This paper presents an innovative hearing system. The hearing system generates audible sound in the ears without any receivers, and no one can hear the generated sound except the user. The theory for generating audible sound is based on a self-demodulation effect which arises from the nonlinearity of the transmission medium. The nonlinear acoustics of the human body allow ultrasonic waves to interact in the transmission medium. When two ultrasonic waves with different frequencies are transmitted through the human body, an audio signal at the difference frequency of two waves is produced in the ears due to the self-demodulation effect.

    In this paper we propose a design using multiple remotely enhanced hand-computer interaction devices (REHCID) to design a real-time breathing detection system. Due to the restricted detection angle of our previously proposed system, unstable detection can be encountered when patients turn the body over. Our new REHCID placed on both sides of the bed allow the system to detect the patient's breathing regardless of his posture. Our design uses both an Infrared (IR) illuminator projected onto the patient's chest and an IR camera to detect the location of the IR LED. We then transport the IR location to the computer by means of Bluetooth. As the infrared rays are invisible, this design can still detect effectively in a dim environment, without at all influencing the quality of the patient's sleep. View full abstract»

    In this paper we propose a compatible design using a smartphone, Bluetooth technology and the Internet to build a wireless physiological measurement system which works in cooperation with a health management function. The advantages in our design include easy portability, high compatibility, small size, wireless connection, low cost and service efficiency. The physiological measurements module provides the necessary measurements such as blood pressure, heart rate, body temperature and electrocardiogram (ECG) results. That information is important for the doctor when diagnosing a patient's health status. The user can easily install the application software on one of three major smartphone platforms. The smartphone, which has been successfully used for physiological measurement (PM) concurrently with Bluetooth technology, receives the measurement through the Internet and sends the result to the remote data center storage.

    The amplify-and-forward protocol is a simple but effective relaying for cooperative communications systems because its associated relay node does not take encoding/decoding into consideration to re-transmit signals. However, the interference and multipath fades during the previous hop are also amplified. In this paper, based on the zero-forcing (ZF) concept, an adaptive amplification factor is investigated to counteract the effects of the multipath-fading channel. Numerical results show that the ZF-based adaptive amplification according to both channel impulse responses possesses the best system performance in a dual-hop cooperative system.

    In this paper we use the accelerometer of a smart phone to design and implement a fall monitor with mobility detection function for the user. We not only analyze the change of acceleration but also analyze the four typical actions of humans. These are going upstairs, going downstairs, standing up, sitting down, running and jumping. Then we compare the four actions with the characteristics of a fall. These are weightlessness, impact, immobility and overturning of the body. Because the waist is the center of gravity in the human body, our system is used more effectively when we place the smart phone at the waist. Our system is based on an open source system platform and the accelerometer in the smart phone. View full abstract»

    The most common brain-computer interface (BCI) systems use electroencephalographic (EEG) signals to communicate human cognitive or sensory-motor brain activities. Those non-invasive BCI systems rely on large number (up to 128) of wet (using conductive gel) electrodes for higher detection accuracy and good signal to noise ratio (SNR). They are studied and designed primarily with focus on medical applications. The electrodes are usually mounted on a special cap and connected through multiple wires. The proper positioning of the cap requires assistance and takes significant amount of time. In this work we review the principles for EEG signal processing and feature extraction most suitable for applications in consumer electronics. Further, we propose a motor imagery brain-computer interface (BCI) based system, using only two active easy to set dry electrodes connected wirelessly with a consumer electronic device. The proposed system relies on the optimal use of event related synchronization (ERS) and desynchronization (DRS) across three distinct EEG frequency bands in order to improve the detection and reduce the training time to only 10 sec. We present our ongoing research investigating the detection accuracy with different signal preprocessing techniques and feature extraction methods. The proposed system aims at making brain-computer interfaces popular with consumer products, providing a more natural human computer interaction (HCI). View full abstract»

    In this paper we utilize a light sensor device with a fuzzy logic controller (FLC) to sense the brightness of different environments and to automatically adjust backlight brightness to a level that allows the user's eyes to be comfortable. Simultaneously this device also reduces the power consumption of the LCD panel. A common operating system defines the light sensor at present, and we add the FLC method to have the light sensor incorporate a flexible adjustment of the backlight brightness. Our structural design communicates with the light sensor by means of a low-power embedded controller (EC). By utilizing the light sensor this design detects the environment brightness, inputs the brightness value into the FLC and adjusts the backlight brightness with the EC according to the output value from the brightness duty range, 0-100%.

    Management of household appliances and the services have been complicated by increasing of network devices recently. Therefore, Home Gateway (HGW) which manages them intensively has been expected as new consumer electronics. However, HGW has not been popular in our life because the installation cost of HGW is expensive compared with the benefits of services. In this study, we propose new home network system architecture working with not HGW but cloud computing for home management as a resolution. Basic and real-time applications are realized by M2M (Machine-to-Machine) communication between household devices under the local network area and, sophisticated and non-real-time applications are managed on the network cloud and control the household devices via internet. With some examples of home network service, proposed architecture are designed and evaluated at various points of view. View full abstract»

    People in a color image, particularly facial patterns are important and interesting visual object. Thus, color reproduction for skin tone becomes the foremost treatment, because skin color is a key memory color in color application systems. Previous studies suggested skin color reproduction by mapping only to the center value of preferred skin region. However, it is not suitable to determine one preference color because preference color from the observer's preference test is not dominant. In this paper, selective skin color reproduction using preferred skin colors is proposed. The proposed method first defines preferred skin colors according to their luminance level. Next skin color is detected by using skin and feature map. After that, each corresponding preferred skin color is determined for each skin region. Finally, input skin color is proportionally mapped toward preferred skin color according to the difference between input skin color and preferred skin color, smoothly reproducing skin color. Through the experimental results, the proposed method achieves preferred skin color reproduction. View full abstract»

    This paper presents a color enhancement algorithm based on multi-scale gray world algorithm for faded images. First, the proposed method adopts local process by using multi-scale mask. The coefficients for each multi-scale mask are obtained to apply the gray world algorithm. Then, integrating the coefficients with weights is performed to calculate correction ratio for red and blue channels in the gray world assumption. Finally, the corrected image is obtained by applying the integrated coefficients to the gray world algorithm. In the experimental results, the proposed method reproduces better colors for both wholly and partially faded images compared with the previous methods. View full abstract»

    With the increase of image resolution in video application, the memory bandwidth is a critical problem in video coding. An embedded compression algorithm is a technique that can compress the frame data when stored in memory. It is possible to reduce memory requirements. In this paper, we propose a lossless embedded compression algorithm with context-based error compensation to reduce the memory bandwidth requirement. Experimental results have shown at least 50% memory bandwidth reduction on average and the data reduction ratio of the proposed algorithm is up to 5% higher than previously proposed lossless embedded compression algorithm [2].

    The paper presented a technique of generating a CIS video panoramic image without rolling shutter distortion. When an image is captured by a rolling shutter camera in motion during a shuttering time, the captured image showed a distortion due to a rolling shutter mechanism and thus, a panoramic image stitched together with a sequence of those images also looked distorted. To solve the problem, a CIS distortion correction method is applied to a conventional video panoramic image method. The proposed CIS video panoramic image method estimates distortion parameters from two consecutive frames assuming that the global motion of two consecutive frames is affine and then, generates a distortion-free panoramic image while there are artifacts in a conventional video panoramic image.

    In this paper, an L-band (1-2 GHz) microwave radiometer system prototype for subsurface temperature measurement is developed and evaluated. In combination with a microwave heating source, this system will be used for the evaluation of blood perfusion, where the temperature of the tissue is raised by the source, and the temperature decay read by this radiometer is used for evaluating the perfusion. Besides the intended application, the main novelty of this system is using two low noise amplifiers in front of the radiometer's so-called Dicke switch in both the receiver and reference temperature input paths to improve the radiometer sensitivity. Some preliminary results of the developed system are presented. This system can potentially lead to the development of a handheld radiometric system for utilization in industry and healthcare.

From a camera's image, we select left and right ones with an adaptive threshold based on an amount of light entering the camera. Furthermore, we correct distortion of the left and right images by utilizing a new criterion derived from correctness of searching directions. Consequently, an automatic stereoscopic 3D photographing can be achieved. View full abstract»
