This paper describes a system design for testing implantable devices, namely pacemakers, that measures selected pacemaker parameters to indicate their proper functionality or potential malfunction. The resulting signals are interpreted and plotted using the programming interface of MATLAB. The efficiency of the resulting wiring is tested on real pacemakers and compared to the values of commercial programmers. The system is designed for easy and universal measurement of pacemaker parameters for learning purposes in the teaching process.

We propose and experimentally demonstrate optical sensor based on all-fiber Mach-Zehnder interferometer possible use for Weight in Motion (WiM) systems. WiM is a dynamic vehicle weighing system for continuous traffic for protection of road infrastructure. The sensor is based on low-coherence interferometry of two modes. Applying the force (load) on fiber in test arm (its optical path is shorter than optical path of fiber placed in reference arm) of interferometer changes visibility of interference pattern. The design of deforming environment is also investigated. In addition, the sensor can be designed to be temperature independent.

This paper describes a distance measurement process, tracking the environment, and determining the presence of space obstacles. The ultrasonic module HC-SR04 is used to measure the distance. This module is complemented by a servo motor, which allows gradual monitoring of the surroundings. The way of signaling obstacles in the space is realized via the vibrating motor. All information about the measured distance is then transmitted to the computer via the Bluetooth module, where is created graphical user interface in the MATLAB program. The system is designed to enable orientation in space for people with visual impairments.

A model of determining the time necessary for induction heating of a ferromagnetic cylindrical charge to the Curie temperature is presented, together with finding its sensitivity to variable input parameters. While the geometry of the inductor and charge are known together with the frequency of the field current, the input variables are represented by electromagnetic and thermal properties of the charge (nonlinear saturation curve, temperature dependence of its magnetic permeability and temperature dependencies of electric and thermal conductivities and specific heat capacity). The methodology is illustrated with a typical example.

Laboratory exercises play a key role in demonstrating the importance of measurement in physics and engineering to students. If properly designed, the students can benefit from them enormously. We describe our reform of the Electricity and Magnetism Laboratory and how the electrical engineering students evaluated it.

This article presents a method for detection of cognitive defects based on eye tracking and saliency maps. The main goal of our paper is to augment the original approach using saliency maps and correlation matrices by introducing orthogonal transforms, namely–DHYT, DST, DCT2 and DCT3. It was shown that combination of various orthogonal transforms provided different results, which are discussed in the article. Experimental data were measured using eye tracker tool for a group of healthy (22) and diagnosed (22) individuals exposed to the Rorschach inkblot test. On average the measured accuracies reached scores over 70% which forms a solid basis for automated prescreening deployment.

To find the solutions to various technical issues in image processing we often want to be able to obtain not only color but also depth information. Information about the depth helps with a better understanding and description of the scene. As a practical matter, we aim to convert the geometrical information about the object to the digital format with the highest possible accuracy. For such a conversion there are many existing methods of creating a 3D model, e.g. photogrammetry, laser scanners. These methods provide high-quality 3D information; however, they are high-priced and often limited by the size of both scanner and object and the scanning time. As an alternative, we present an optical depth sensor that can be used excluding other emerging disadvantages with lower quality of an output model though. In the future, we consider the usage of the selected sensor for specific biomedical application: diagnostic support of obstructive sleep apnea.

The paper deals with the issue of electromagnetic non-destructive investigation of real fatigue defects of conductive materials. Austenitic stainless steel of grade AISI 316L is investigated by the eddy current method. Harmonic excitation is used for driving of the exciting coils. Presented fatigue cracks are induced by the three-point bending of the plates on the cycling machine with predefined loading process parameters. The gained response signals of the investigated regions of interest are graphically presented and discussed in the article.
