This paper demonstrates a system capable of capturing directionaltidal breathing (inhale/exhale cycles) pattern for application inpulmonary disease diagnostics. The work particularly highlightsintelligent usage of commercially available Analog Device’s phasegainIC and ultrasound to build such a system which otherwiserequires many fold, more complex circuits/electronics to achievesimilar sensitivity...
This paper presents a simulation model to quantify the amount of light intensity dissipated by the skin and its underlying layers. The model will be useful to eliminate the skin structure variability issue in the blood pressure measurement system. In the visible spectral region, the absorption & scattering properties of skin tissues are estimated by taking into account the spatial distribution...
This paper presents a smartphone based application whereby a vehicle owner can obtain a reasonable prediction of the vehicle's potential failure time. Through a hybrid model-based and data-driven approach, one can obtain a predictive maintenance suggestion; given the current state of degradation. The smartphone is used both for sensing and computation. The proposed minimal-sensing approach is only...
To design measurement systems, appropriate data models and measurement models need to be defined, which can be used for instrument calibration. Data and measurement models using the Wigner-Ville distribution are proposed for measurement of events on vehicular accelerometer data, which is a self-similar non-stationary random process. Model variables and parameters are defined which can be chosen to...
The Global Positioning System (GPS) receivers are now an integral part of smartphones. However, phone based GPS measurements display much less accuracy as compared to professional grade receivers. On the other hand, the deep penetration of smartphones in consumer market offers opportunity for customizing new solutions. One such possible application is targeted towards identifying risky driving profile...
Accelerometer data collected from moving vehicles can be modeled as a self-similar random process. A Renyi entropy measure computed over the Wigner-Ville distribution of this non-stationary process is used to select the most relevant data samples for compression. Wavelet transform based transform coding is applied to compress the accelerometer data with minimal distortion and accurate inferences (detection...
Assessment of driving behavior and estimation of risk therein is an important use case for telematics and vehicular networking technology domain, which has gained interest in the fleet management and consumer verticals, but above all with the car insurance firms. These firms have started incorporating the results of such analysis to provide their customers with "pay as you drive" insurance...
A novel method for admittance calculation of two gap‐coupled sectoral patch antennas is described for wide band applications.Admittance is calculated both numerically and experimentally. The results of antenna are computed by the developed model and compared with the experimentally measured results of the designed antenna. The numerical results obtained are in good agreement with the experimental...
