    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (307 KB) | HTML iconHTML

    In this paper, a hypercomplex model of acoustic vector sensor arrays is first introduced. Namely, the hypercomplex number is used to model the four components of the output signals of an acoustic vector sensor in a holistic manner. Then we use the MUSIC-like algorithm based on the hypercomplex eigenvalue decomposition to estimate the direction of arrival (DOA) of the signals. Both theoretical and ... View full abstract»

    This paper presents the design, implementation and test results of an online system for instantaneous measurement and display of fuel consumption in a vehicle. By utilizing the existing available sensors for input, the overall cost and complexity of the system is greatly reduced. The system is intended to help reduce the fuel consumption, thereby reducing the cost of running the vehicle. The instr... View full abstract»

    In everyday life many actions are secured and/or authenticated by use of a secret personal identification number (PIN). This paper reports an improvement to the security afforded by a numeric PIN system through the addition of a covert biometric identification process. This biometric identification process is achieved through the use of a modified keypad incorporating force sensors within the indi... View full abstract»

    In this paper we present a low-power interface for eddy current displacement sensors with digital output. A measurement method and a new front-end circuit are proposed. The front-end circuit demonstrates an excellent thermal stability, high-resolution and low power consumption. The demodulation principle, as well as the interface implementation, is addressed. This interface is introduced for measu... View full abstract»

  • Accurate Estimation of Moving Average Models with Durbin's method

    The best accuracy for estimated spectra is obtained with parsimonious time series models, which have the smallest number of parameters to guarantee unbiased models. Durbin 's method for the estimation of moving average (MA) parameters uses the estimated parameters of a long autoregressive (AR) model to calculate MA parameters. Probably all pejorative remarks on the quality of Durbin's method in th... View full abstract»

  • Optimal knot selection for least-squares fitting of noisy data with spline functions

    An automatic data-smoothing algorithm for data from digital oscilloscopes is described. The algorithm adjusts the bandwidth of the filtering as a function of time to provide minimum mean squared error at each time. It produces an estimate of the root-mean-square error as a function of time and does so without any statistical assumptions about the unknown signal. The algorithm is based on least-squ...

    Most existing algorithms for the spectral analysis of irregularly sampled random processes can estimate the spectral density until frequencies up to the mean data rate or somewhat higher. A new time series method extended that frequency range with a factor thousand or more, for certain processes. Two requirements have been found for the new algorithm to give useful results. Firstly, at least about... View full abstract»

    This work presents the investigation of volume control for hearing aids using objective speech intelligibility measures. In order to effectively assess the impact of various volume levels on speech intelligibility for the hearing impaired, we propose a new method to measure speech intelligibility by modifying the coherence speech intelligibility index measurement. In the proposed method, the one-t... View full abstract»

    This paper describes a procedure for comparing calibrated nonlinear radio-frequency (RF) measurements performed on a nonlinear device by five different measurement laboratories. The device-under-test is a nonlinear active semiconductor device that is designed to generate a maximum number of harmonic tones. The goal is to obtain a simple, automated method that detects if some laboratory had measure... View full abstract»

    An original measurement system for nonlinear RF power amplifier characterization is presented. This new setup enables AM-AM and AM-PM measurements using one six-port reflectometer as a traveling wave ratio calculator. Experimental results of a commercial power amplifier at 2 GHz are presented and compared to those performed using a vector network analyzer. View full abstract»
