The production of highly reliable, electronic devices is a source for significant environmental emissions and energy consumption. A modern, cost-effective and modular design can enhance product maintainability and lifetime. Many end-users would certainly be willing to devote more resources (money) for a device they use, if, in return, they could extend the life of the device. This paper introduces the architecture for a high-reliability, modular, end-user-configurable, redundant power supply, based on these principles.

This article deals with components (that effectuate the electronic protection) of property protection systems. Within this, mostly with to delineate the electronic outdoor protection, the intrusion detection system and some possible additional functions of the access control system. The solutions presented here are aimed to keep the cost low from the viewpoint of hardware requirements, together with to take advantage of the software opportunities.
