In this article a safe and affordable system of medicaments dispensation is described. The system can be utilized in both hospital and home environments. The main purpose of the device is medicament dispensation accordingly to doctor prescriptions. As a first element of the system a safe medicament dispenser prototype was built. The device is designed to fulfill the needs of patients forced to take...
Most of the modern industrial automation systems are based on Programmable Logic Controllers (PLC). Continuous development of wireless technologies makes them more and more popular in automation applications. However, there are still fields were none of the available solutions can be applied. An example of such an application is integration of real-time wireless sensor networks with automation systems...
The paper describes a prototype of wireless sensor network for monitoring of greenhouse environmental conditions including temperature and soil moisture. The proposed system consists of measurement nodes powered from small-size solar cells and a central node that can be connected to a Personal Computer via USB or work independently. The wireless sensor nodes are responsible for signal acquisition,...
The paper describes components of power supply block for wireless sensor nodes powered from harvested mechanical vibration energy which is converted into electric energy. The properties of vibration energy harvesters and assumed power requirements for wireless sensor nodes are given. General structure of power supply block is proposed. Various possible structures of AC/DC rectifiers and DC/DC converters...
During the operation of linear accelerators, gamma and neutron radiation is produced. Gamma radiation causes semiconductor degradation. Therefore, it is necessary to replace electronic devices when the maximum allowed dose is reached to ensure reliable operation of the accelerator. Neutron radiation causes soft errors in memories and registers because of Single Event Upsets (SEUs). This may disturb...
