In utilizing CMOS-MEMS resonators as mass-sensitive platforms, a uniform temperature distribution on the membrane surface is critical. In this paper, a novel design of CMOS-MEMS resonator with embedded microheater to control the temperature over the sensing layer was successfully designed and characterized. The CMOS-MEMS resonator was fabricated using 0.35 µm CMOS and post-CMOS micromachining process...
Lane detection plays an important role in intelligent vehicle systems. Therefore, this paper presents a robust road lane marker detection algorithm to detect the left and right lane markers. The algorithm consists of optimization of Canny edge detection and Hough Transform. The system captures images from a front viewing vision sensor placed facing the road behind the windscreen as input. Then a series...
This paper presents the design of linear permanent magnet generator for wave energy conversion. The main focus is to design a linear generator which is simple, lightweight and produce 1000 W electric power. Various types of linear generators are studied such as; Transverse flux, vernier-hybrid and iron-cored. The air-cored linear permanent magnet generator is selected as it eliminates cogging force...
A Bus Driver (BD) controller design is presented in this investigation, where all of the hazard detection and protection required by FlexRay 3.0.1 are integrated and realized, including under-voltage (UV), bus failure, wake-up detection, etc. The required 4-state transition for FlexRay BD control is also carried out to coordinate the interfacing and signaling among the ECU (electronic control unit)...
Specular illumination in digital images is one of the main causes, affecting the performance of image analysis techniques. The causes of this artifact include shiny nature of the surface on which the light is falling and the intensity and distribution of light. In this paper, it is explained that how specularly illuminated spots in the color images of acne patients can be detected and compensated...
This paper proposes an architecture for structured low density parity check encoder. The proposed architecture supports the limitation of input/output pins of field programmable gate array using division of information bits. The division of information bits generates latency of encoding. The proposed architecture does not store the required matrix for bit-wise multiplication and does not use cyclic...
MEG is an emerging clinical tool to gather insight on neuronal dysfunction inside the human brain. This paper analyzes data saved as FIF file format at a small-world level. Traditionally, operating cost is very high for artifact removal. Also, the absence of a standardization with availability of more than a dozen MEG recording device vendors makes it difficult to store and process data followed by...
Visual surveillance system for tracking crowd using multiple cameras at dynamic backgrounds faces many challenges such as illumination variance, occultation, low spatial temporal resolution, sleeping person, shadows and camera noise. In this paper we address the issue of gradual and sudden illumination variance caused by movement of the sun and the clouds. We evaluate Mixture of Gaussian method and...
The assessment of a drivers' cognitive distraction during driving is a challenging topic in research community. This paper states the ongoing research assessing driver's cognitive distraction using simulated driving. The driver's cognitive distraction detection is based on the analysis of EEG signal. A new analysis method based on Singular Value Decomposition (SVD) is introduced for the extraction...
In this work, we propose a PMOS based wide swing cascode current mirror (WSSCM) for 0.35 um CMOS-MEMS technology. The proposed circuit shows a high bandwidth current mirror with high output resistance capability operating at low voltage levels. Noise, output resistance and bandwidth analysis are presented. CADENCE SPECTRE circuit design tool using MIMOS 0.35 um and BSIM3 transistor models is used...
In this paper, a single fault (short or open) on a single sided printed circuit board (PCB) interconnect was experimented. The induced magnetic fields of faulty and fault free interconnects were detected by a planar array-coil sensor using eddy current testing (ECT) principle. The experimental results have shown that in the presence of a short fault, the differences between the induced voltages from...
Automatic Modulation Classification (AMC) is extremely desirable to realize the merits of cognitive radios in plethora of commercial and military applications. However, AMC is extremely challenging in real-world scenarios due to multipath fading and additive Gaussian noise on modulation schemes. Moreover, it becomes more difficult in blind environments where a little or no priori information about...
A parametric model is proposed to predict the amplitude-normalized central aortic pressure (CAP) waveform from the radial photoplethysmogram (PPG). The structure of the model is linear autoregressive with exogenous input (ARX [2 2 0]). Results show that a second order model can predict the radial PPG from the normalized-CAP with a fitness value above 88%. One application of this technique is to accurately...
Wireless infrared communications (WIR) is explained as the light waves propagation in free space by means of infrared radiation which exists in 400–700nm.This range corresponds to high frequency range which is useful for higher data rate applications. Therefore, wireless infrared is applied for higher data rates applications such as wireless computing, wireless video and wireless multimedia communication...
An end-coupled line bandpass filter (BPF) is proposed and designed by placing defected ground structure (DGS) in the ground plane. DGS is used for its property of miniaturizing the size of microwave filter and also improving the mutual coupling between the resonators. The proposed dumbbell shaped DGS is used to tune the bandpass filter to 2.4 GHz with dimension of 44 mm × 18 mm. A wide tuning range...
In this paper a fuzzy logic controller was developed for a parabolic dish antenna system. Friction is one of the disturbances associated such systems and was represented with dead zone in the Simulink block. The effect of the disturbance due to the friction was investigated by simulation using Simulink/MATLAB 2012a software. The results obtained from the system with the fuzzy logic controller were...
There is a great need to design experimental setup to deal with the fundamental material issues in MEMS. Cantilever being the active part of MEMS is modeled using COMSOL Multiphysics.
