AB  - Two methods developed to improve the classical time constant count rate meters by using the adaptive signal-processing tools are presented. An optimized detection algorithm that senses the change of the mean count rate was implemented in both methods. Three different types of low-pass filters of various structures with adaptive parameters to implement the control of the mean count rate error by suppressing the fluctuations in a controllable way were considered, and one of them was implemented in both methods. An adaptation algorithm for time constant interval calculation was executed after the low-pass filter was devised and implemented in the first method. This adaptation algorithm makes it possible to obtain shorter time constant intervals for higher stationary mean count rates. The adaptation algorithm for time constant interval calculation executed before the low-pass filter was devised and implemented in the second method. This adaptation algorithm enables sensing of the rapid change of the mean count rate before the fluctuations suppression is carried out. Some parameters were fixed to their optimum values after appropriate optimization procedures had been performed. The implemented low-pass filter has variable number of stationary coefficients depending on the specified error and the mean count rate. It implements the control of the mean count rate error by suppressing the fluctuations in a controllable way. The simulated and realized methods, using the developed algorithms, guarantee: a response time not in excess of 2 s for a mean count rate higher than 2 counts/s and a controllable mean count rate error in the range of 4-10%.

AB  - Two optimized adaptive digital signal processors were developed to implement the preset time count rate meters. The first processor improves stationary characteristics of the count rate meter by implementing the control of the error of the mean count rate when the changes of the mean count rate are only due to its stochastic nature. The second processor is focused on dynamic characteristics. Its time response is made adaptive to the changes of the mean count rate which are due to increased or decreased radiation levels. The change of the mean count rate is sensed by a specially devised detection algorithm. Three mean count rate meters, based on the developed adaptive digital signal processors, were realized and were used for experimental validation of proposed adaptive digital signal processors. The experimental results, conducted without and with radioisotope for the specified errors of 10% and 5%, showed to agree well with theoretical predictions. (c) 2005 Elsevier B.V.

AB  - A smart piezoresistive pressure sensor using a microcontroller is described. The microcontroller ensures temperature compensation and linearization of the sensor, as well as the data exchange. To compensate for the sensors imperfection, approximation of the sensor inverse response function by a second-order polynomial in terms of pressure and temperature is used. The maximum measurement error with respect to the full measurement range lies within +/-0.1%;, compared to the ideal sensor response function within the temperature range of 0-70 degreesC.
