Then, we propose an integrated approach for moving object detection to get the descriptions used for smart video sensor. A statistical algorithm is used to obtain the background model, which is updated real time in order to adapt to changes of illumination and objects in the scene. After applying a threshold to separate candidates in foreground and background, morphologic analysis and area measurement of connected region are used to eliminate background disturbances. Finally, the shadow is detected using HSV color space information to get accurate moving objects. The results of experiments showed a satisfied performance with the proposed approach.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

Moreover, in practice, relative motion between the probe held by doctor and the blood flow also induce the clutter along with blood flow. If there is not clutter rejection, the estimation value of low velocity blood flow will be inaccurate, and the CFM imaging quality will be poor. In this paper a new adaptive filtering scheme is introduced. In this scheme statistical theory is used to calculate the mean frequency and variance of clutter signal. The mean frequency is used to mix down the Doppler signal, and the variance determines the filter's cut-off frequency. So it achieves the adaptability of the clutter rejection filter and improves the accuracy and flexibility of the ultrasound devices.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

The basic building block is the measurement service, i.e. a software object properly configured and made remotely accessible across a network. A measurement service corresponds either to a single (virtual or physical) instrument, or to a collection of measurement services abstracting a test method. Service attributes include the graphical interface which supports user interactions. MADAMS is especially tuned to: (i) defining a common and straightforward way to use distributed measurement services; (ii) introducing a data-exchange layer for inter-instrument communications; and (iii) exploiting a design pattern which separates definition of service functionalities from distribution concerns. This paper introduces MADAMS, outlines its current implementation which depends on Java/Jini, and shows its application to a demand monitoring-control measurement system.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

Torque and power are calculated automatically on the receiver side from samples processed in real time and displayed to the user. Moreover, the system provides analog and digital outputs of the shaft vibration waveform for oscilloscope observation or recording on a personal computer in a digital format.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

As a result, image quality and target recognition can be improved significantly. In addition, experimental evidence is presented where scattered light exhibits higher retention of the original polarization with increasing scatterer concentration, within a range of observations.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

The instrumentation system employed in this investigation is as an integral part of a multi-functional flame monitoring system, being capable of monitoring oscillatory frequencies of a flame on a two-dimensional and concurrent basis. A quantitative flicker frequency is defined as the power-density-weighted mean frequency over the spectral range to represent the oscillatory characteristics of a specific region of the flame. A series of tests was undertaken on an industrial-scale coal-fired combustion test facility under a range of operating conditions. Relationships between the measured flame flicker and the process data including emissions are identified. Results obtained demonstrate that the flame flicker responds in predictable ways to the effects of operating conditions on the dynamic nature of the flame.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

In this paper, the jitter refers to the one caused by radiated electromagnetic interference (EMI) noise, which is present in the head of all ATE due to DC-DC converter activity. An initial analysis of the areas of the head board most sensitive to EMI noise has been made. It identifies a sensitive part in the loop filler of a phase locked loop which is used to obtain a high frequency clock for the timing generator. Different H-fields are then applied externally at the loop filter to verify the behavior of the output signal of the head board in terms of RMS jitter. As for RMS jitter measurements, a frequency domain methodology has been employed. A trend for RMS jitter variation with respect to radiated EMI magnitude as well as frequency has been obtained. Also the orientation of the external H-field source with respect to the target board and its effects on the measured RMS jitter has been investigated. For measuring the RMS value, a proper circuitry has been designed on a daughter board to circumvent ground noise and connectivity problems arising from the head environment.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.
