An on-chip bipolar transistor is used to accurately determine the sensor's temperature during calibration. The transistor's base-emitter voltage is measured at three collector currents to find the absolute temperature while compensating for series resistances. The technique does not increase the pin count for a typical smart sensor, as the transistor can be accessed via the supply pins and an existing digital input pin. Measurements on substrate pnp's in a standard CMOS process show that the temperature can be determined with an accuracy of /spl plusmn/0.1/spl deg/C in the range of -50-130/spl deg/C.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

This MEE estimator is extended to measurement estimation and pdf approximation when /spl rho/(e) is unknown. The entropy criterion is constructed on the basis of a symmetrized kernel estimate /spl rho//spl circ/n,h (e) of /spl rho/(e). The MEE performance is generally better than the Maximum Likelihood (ML) estimator. The bandwidth selection procedure is a crucial task to assure consistency of kernel estimates. Moreover, recent proposed Hilbert kernels avoid the use of bandwidth, improving the consistency of the kernel estimate. A comparison between results obtained with normal, cosine and Hilbert kernels is presented.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

These control systems are composed of intelligent sensors and actuators (with calculation capabilities and communication interfaces), processing units, and a communication network, e.g. fieldbus or real-time network. The modeling of the system is ensured thanks to Petri Nets. Color Petri Nets allow the evaluation of both the dependability aspects and the performances with a control point of view. In order to get some results, it is possible to achieve a simulation or to make an analysis of the occurrence graph. The work presented is a model of a tank, in which the level of the liquid is controlled. An analogue sensor is used for the measurement of the level and is used for the control of the pump which fill the tank. The sensor is extended by some possibilities not to supply the controller with a measurement, as a result of a failure, and a degraded strategy can so be set. The evaluation of the reachability of this state after failure is achieved thanks to the occurrence graph tool. The global aim is to propose a methodology for the evaluation and comparison of distributed architectures.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

This disease causes considerable damage to the cattlemen whilst reducing the quantity and the quality of the produced milk. An early detection and corrective action can lead to early cure. Although the universal method to measure mastitis levels is by determining the somatic cell counts per milliliter of milk, the electrical conductivity of milk is a rapid test for checking the acceptability of milk to monitor the effects of udder infection. This work presents the design of a low cost mastitis detector in cows using ac conductivity measurements.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.
