Incessantly extending possibilities of safety PLCs allows usage not only in process level control but also in higher level of control. It means, that complex distributed control systems can be created. In case that safety functions are realised by these systems, architecture of con...

In many applications, a light curtain is used to detect the intrusion of a human (or other protected object) into the danger zone. After detecting the interruption of the light curtain, a safety function is activated to bring the danger zone into a safe state (non-human)....

In the automotive industry, the integration of different functions is a challenging and transdisciplinary task. The effects caused by the timing behavior of discrete controllers on the control plant need to be understood during development. In this paper we show how co-simulation of...

Simple cross parity check codes have been well known for decades in the areas of magnetic recording and radiation-hardened memory in space applications. However, the computational power requirements of higher dimensional cross codes mean that priority has been given to different forward ...

We propose a method of characterization and assessment of the uniformity of the surface properties of samples based on a set of derived parameters. Local (sliding window) variance, Allan and Hadamard variances and centers of potential for measurement lines are used to assess the&#x...

We introduce and analyze a set of essentially discontinuous functions, based on multiplicative inverse of the time, which are usable as chirp signals. An advantage of these chirps is that they can be chosen from a large class to allow multiple radar operators to use each&...

Autonomy in vehicles is a rapidly expanding technology that is of interest in many major car companies. Autonomous driving enables safer journeys by removing human error in driving, as well as reducing driving time and fuel consumption by optimizing the engine and brake actuation.&...

Cardiac output (CO) is a key parameter in the assessment of cardiac function, and its measurement is fundamental to the diagnosis, treatment, and prognostic evaluation of all heart diseases. In this paper the linear and nonlinear models for noninvasive estimation of CO are presente...

The paper deals with a problem of modeling of dynamic systems. The proposed approach to the problem solution is based on modified Tellegen’s theorem well known from electrical engineering. The novelty of this approach is that it is based on the instantaneous power calculation ...

The presented method automatically adjusts the deadtime of gallium nitride (GaN) transistors in half-bridge to increase the efficiency. This removes the need of manual measuring and setting the deadtime of the finished converter. The developed algorithm was tested and compared with the ...

With the rise of Artificial Intelligence (AI), it is becoming a significant phenomenon in our lives. As with many other powerful tools, AI brings many advantages but many risks as well. Predictions and automation can significantly help in our everyday lives. However, sending our&#x...

In this paper a design method for mechatronic functions in an early design phase under consideration of the requirements of functional safety is proposed [14]. The goal of the method is to discover threats for the safety goals and to prove or optimize the diagnostic mecha...

Slip controller is an essential part of the locomotive controller because it enables maximum force transfer and increases the service life of the locomotive parts. The modern slip controllers try to determine actual adhesion parameters and set the required tractive force to avoid s...

This short report describes completely analog circuit realization of the so-called Rucklidge equations. Design process is systematic and supported by a circuit-oriented numerical analysis (bifurcation diagrams and Lyapunov exponents) and real experimental verification via the oscilloscope screenshots. Oscillato...
