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.

When a speaker stands in front of a projector screen for a presentation, the eyes will be hurt by the direct light from the digital projector. This paper proposes a design to reduce the strong light by projecting a black round mask on the speaker's head. The black round mask is superimposed to the slide frame by the software of this design and the mask traces the speaker's head. The depth camera captures the depth images from the speaker with the projector screen. The location of the speaker's head is determined by using the middleware components to process the depth images. This design efficiently continues to trace the head location. The computer uses this head location and superimposes a black round mask to reduce the uncomfortable feeling caused by the strong light of the projector.

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%.

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.

A novel portable and wireless biomedical monitoring system featuring on demand wireless data transmission of ECG signals and time-frequency HRV analysis for personal and home healthcare applications is presented in this work. In order to provide comfort and convenience to patients, the device's size, power consumption and portability are of first priority. The ECG processor based on previous hardware design [1] acquires three-channel ECG biomedical raw data through an analog front-end (AFE) circuit, and it measures the time between successive heart beats on lead II as RR intervals for HRV analysis. Functions such as QRS complex peak detection, RR intervals calculation, and time-frequency analysis of HRV have also been developed in hardware. A real-time HRV analysis processor is realized by employing a Lomb periodogram for time-frequency power spectral density (PSD) analysis of the heart rate. The proposed ECG monitoring system has been implemented in Field-Programmable Gate Arrays (FPGA) and it features high integration density, portability, wireless transmission and low cost.

This system aims to provide a low-cost means of monitoring a vehicle's performance and tracking by communicating the obtained data to a mobile device via Bluetooth. Then the results can be viewed by the user to monitor fuel consumption and other vital vehicle electromechanical parameters. Data can also be sent to the vehicle's maintenance department which may be used to detect and predict faults in the vehicle. This is done by collecting live readings from the engine control unit (ECU) utilizing the vehicle's built in on-board diagnostics system (OBD). An electronic hardware unit is built to carry-out the interface between the vehicle's OBD system and a Bluetooth module, which in part communicates with an Android-based mobile device. The mobile device is capable of transmitting data to a server using cellular internet connection.

In this paper we represent a wearable wrist device for runners that is equipped with a GPS chip and programmable features. While running, the device would offer velocity, distance and time measurements at a glance. A button to begin and end a tagged area would also be available so that runners could mark particular parts of their run over which they wish to improve their time. The primary components of the proposed wrist device are as follows: a Microchip dsPIC 33FJ128MC802, a Sparkfun 128×128 pixel color LCD, and the LS20031 GPS chip, also available through Sparkfun. However, these components will be reviewed again and replaced with more suitable ones later.

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.

In this study, a method based on Hilbert-Huang Transformation (HHT) for time-frequency analysis of heart sound signals is presented. HHT is employed because most biomedical signals such as Electroencephalogram (EEG), Electrocardiogram (ECG) and heart sound signals are non-stationary signals. Heart sound signals recordings are often contaminated with the spike noise caused by the front-end circuits or measurement instruments in the real situations. A digital median filter is firstly employed to remove the spike noise of the heart sound signals. Then, the time series data are decomposed into several IMFs (Intrinsic Mode Function) using Empirical Mode Decomposition (EMD) algorithm. Hilbert transformation algorithm is utilized to acquire the instantaneous frequency for every IMF. Simulation results show that time-frequency domain analysis of heart sounds signals based on HHT algorithm is able to offer higher frequency resolution.
