Reliable software development and methods to validate programming code and source code gain nowadays more importance and will be even more significant in the future. It is not enough that the developer has understood the task, but it has to be validated that from simulation to the actual desired hardware the developed code is functioning correctly. This(More)
Blood pressure is a significant vital sign; blood pressure monitoring has a great significance to determine the health status of parents. This paper proposes a continuous, non-invasive blood pressure monitoring system concept, which requires a minimum of calibrations. Using the changes in Pulse Transit Time (PTT) to derive changes in blood pressure is a new(More)
In recent years, Pulse Transit Time (PTT) based non-invasive continuous blood pressure monitoring systems have been investigated extensively. But the most relevant studies did not pay attention to the safety requirement of the system. In this paper a method is proposed to model the safety-related system for continuous noninvasive blood pressure monitoring.(More)
This paper proposes a continuous, non-invasive blood pressure monitoring system concept, which uses a safety microprocessor to connect sensors for building a body sensor network. The changes in Pulse Transit Time (PTT) can be detected with the sensor network. The microprocessor gathers the PTT and other vital signs of the patient to derive changes in blood(More)
A series of functionalized porphyrin molecules containing electron-rich alkynes, synthesized by means of the Sonogashira coupling reaction were further modified by reacting the ethynyl groups with click reagent through a formal [2+2] click reaction. The photophysical and electrochemical properties of the porphyrin derivatives were studied by UV/Vis(More)
