Abstract

The concept of security data transmission in a mobile diagnostic system composed of the process stations (remote parts of the supervising and therapeutic system) and the operator station (local part of the supervising and therapeutic system) is presented. Process stations are connected to the operator station via radio modems. It allows the installation in mobile facilities. Communication between stations is realized via wireless access points. The examples of the application of the presented issues in mobile systems, as well as the potentially locations of the security risks of transmission are given. The possible options for secure communications are described. The assumptions of the concept of a secure communication in the diagnostic system are explained.

Abstract

The purpose of this paper is evaluation of the influence of human saliva and its substitutes on the corrosion resistance of some implant alloys used in stomatology, which included: austenitic steel (316L), titanium alloy (Ti6Al4V), and cobalt alloy (CoCrMo). Corrosion studies were conducted by means of the potentiodynamic method with the application of the VoltaLab 21 kit with VoltaMaster 4 software. The reference electrode was a saturated calomel electrode (SCE), whereas the counter electrode was a platinum electrode. The results of conducted studies indicate an increased current density in the passive range on potentiodynamic curves of studied alloys in the environment of human saliva, and also in a commercial saliva solution - Mucinox. On the basis of conducted corrosion studies, it can be stated that in terms of corrosion resistance the developed saliva substitutes may constitute competitive solutions to commercial saliva substitutes. The prepared substitutes should be studied further from the perspective of practical application for patients. The original value of the paper is a proposition of new saliva substitutes.
