This paper presents a system for hearbeat detection using microwave Doppler technique. Using a vector network analyzer, a microwave system is tested for the detection of the heartbeat signal at a distance of 1 feet from a person. The proposed system shows the ability of detecting the heartbeat signals with the possibility of tuning the radiated power. Measurements are performed at 10dbm, 0dbm, −10dbm,...
This study investigated the effect of continuous tones vibrant on focus ability among teenagers. Three vibrant levels as perceived as Medium, Loud but Comfortable and Very Loud were examined. In 6 subjects, the results showed that the amplitude of N1 waves have reduced significantly when stimulated by Medium sound as compared to Loud but Comfortable and Very Loud stimulation. Insignificant reduction...
This paper presents the overall design of Home Automation System (HAS) with low cost and wireless remote control. This system is designed to assist and provide support in order to fulfil the needs of elderly and disabled in home. Also, the smart home concept in the system improves the standard living at home. The main control system implements wireless Bluetooth technology to provide remote access...
In this paper, presented an analysis and designed structure for Ultra-Wide Band (UWB) band pass filter that was carried out using a composite microstrip line with −10 dB and fractional bandwidth of more than 92%. This designed of band pass filter is suitable for ultra-wide band application system. The proposed filter was designed based on 7th order Chebeyshev with 0.5 dB ripple which operate between...
In this paper, presented an array of 2 × 2 UWB Bowtie antennas for Ultra Wide Band (UWB) mobile communication is being proposed. The antenna designs have been simulated using CST Microwave Studio. The antenna covers the UWB spectrum from 4.0 to 10.6 GHz, and had a return loss below than 10 dB throughout the entire band. A compact antenna area of 56.4 × 76.0 mm2 is obtained. The material used is FR-4...
This paper present a face detection system using radial basis function neural networks with variance spread value. Face detection is the first step in face recognition system. The purpose is to localize and extract the face region from the background that will be fed into the face recognition system for identification. General preprocessing approach was used for normalizing the image and a radial...
Based on the block-matching motion vector estimation techniques, a grid system using the block-based technique is proposed for motion tracking in video sequences. The technique is known as hexagon-diamond grid system (HDGS). The HDGS has a large hexagon and small diamond search pattern based on block-matching motion tracking characteristics. The large hexagon search pattern will capture the motion...
The objective of this paper is to use existing iris recognition methods as an alternative method to detect the presence of cholesterol in blood vessel. This research adopts John Dugan's and Libor Mask's iris recognition methods and alternative medicine, iridology. Based on the iris recognition methods and iridology chart, a Matlab program has been created to detect the present of cholesterol in human...
