The main goal of the research is to increase the measurement resolution of the ultrasonic range finders to meet the needs of vital signs non-contact registration based on the chest movements. The two-phase method is proposed to make distance estimates by sending the probe pulse trains, calculating the phase spectrum of the echo signal’s envelope and tracking its relevant components. During the first phase the rough TOF based estimate is made. During the second phase this estimate is corrected based on the phase spectrum of the echo signal’s envelope, the phase ambiguity is removed and the relevant components are determined. The final estimate of the human chest displacement is calculated based on these relevant components. The output data rate is the same as for the TOF measurements, but the measurement resolution is increased to the one hundredth of the ultrasonic wavelength. The experiment results are provided for the both model and the real human chest displacements caused by the respiration and heartbeat processes.

An important addition to the inertial navigation system are magnetometers. Areas with magnetic field anomalies serve to determine the reference points. But the magnetometers are influenced from both the electrical equipment of the robot itself and robot’s parts configuration. Compensation of the robot’s self-influence on the readings of the magnetometers is carried out by computer tools. In order to obtain the initial data, live experiments are required in a natural enviroment. For simplifying data acquisition about the behavior of magnetometric systems of a mobile robot an facility is used, which allow to compensate the Earth’s magnetic field in a working space and to create an artificial magnetic field that varies according to a predetermined algorithm and simulates a magnetic field in the intended environment of application of the robot. The facility features: a working space, sufficient to place the mobile robot; a coil temperature drift correction; uniformity of the frequency response in operating frequency range; compensation of power supply interference and similar disturbances; sensitivity equalization of control channels; compensation of misalignment coordinate systems of the sensor and coil system. An nteractive Simulink model designed and evaluated. The automated stand created as experimental facility, its parameters proove proposed model adequacy.

An effective functioning of unmanned vehicles demands to process large amounts of various data coming from sensors, on-board data bases etc. Therefore date fusion technology is one of key-technologies for autonomous vehicles and systems. In order to systemize such data processing special so-called data fusion architectures are used (e.g. JDL, Waterfall, Boyd etc.). However some of those have a list of restrictions w. A goal of this paper is to present a novel data fusion architecture which could be used on board of unmanned vehicles. This architecture consists of 5 basic layers: parameters identification, state identification, (object type identification), situation identification and task implementation identification. The proposed architecture has some advantages in comparison to those already in use. Author considers that presented architecture has good visibility, intuitive understanding, possibility for deep feedback usage and good potenial for automatic reconfiguration and self-learning. The developed data fusion architecture can be used for building complex data fusion systems on board of unmanned vehicles as well as of group of vehicles and even of systems of higher hierarchy.

This paper describes results of effectiveness test of simulator for e-training operators of tele-operated vehicles. The test has been conducted with 20 participants (Warsaw Military Univesity of Technology students) divided into two groups. First group, numbering 11 persons, operated Dromader robot without previous training on the simulator. Members of the second 9-persons group went through simulator training before operating the robot. The trial was composed of two exercises. First of them was devoted to test driving abilities of the operators. The task for operator i was to cover the distance in a short time and not making errors (such as deviations from the route or collisions with obstacles) that was scored negatively. The second exercise was devoted to test manipulation abilities, and manipulation concrete blocks with robot’s manipulator was its substance.

The main objective of present study is the definition of bio-functional foods and the investigation of attitude of consumers toward the market and consumption of comestible snails in the wider region of Thessalonica.
The questionnaire of particular study was applied in sample of 353 individuals at the duration: 13 December his 2013 until 28 his April 2014 in the urban group of Thessalonica. The questions that included it was for the most part “closed” type, so that it can become statistical treatment and analysis of elements in order to results a line of conclusions. The analysis of elements became with the use of statistical parcel IBM SPSS statistics 21. The method that was selected as more suitable, for the statistical investigation of attitudes and opinions of consumers, is the categoric regression (Categorical Regression), which constitutes extension of classic statistical technique of analysis of regression, that is used when somebodies of the variables are not numerical or exist suspicion that the relations from each other are not linear.
From the results it results that the socio- economic characteristics (income, age, sex, familial situation, education) Thessalonikeon of consumers influence their consuming tendencies as for the snails , also have been studied the frequency of consumption of snails, the money that allocate the consumers as well as the part in which they prefer they consume him. and finally it has been studied how is influenced the consumption of snails from their particular socio-economic and demographic characteristics.
Finally, are formulated certain proposals that they aim at as, the better promotion and improvement of sector saligkarotrofias, and right promotion of snails in the market.
