User adaptive system for data management in home care maintenance systems

User adaptive systems for data management becoming more important in the home security and maintenance systems. There does exist plenty of monitoring systems with relevant outputs without right driven information between user and maintenance system. Especially the real time biotelemetry system base on vital function monitoring and first-aid treatment are the main focuses for user adaptation. The goal of this work is design and implementation of such kind of maintenance system providing information by user adaptive system for protection and saving haleness and human life. System design consists from hardware implementation of the sensing and transmission part and from logical structure by software implementation with user adaptation.

Security and Reliability of Data Transmissions in Biotelemetric System

Secure and reliable data transmissions are of vial importance in today’s biotelemetric systems. Particularity of biotelemetric data puts special requirements on real biotelemetric system regarding data confidentiality, transport channel reliability, transport latency and latency jitter. This article describes some of conclusions acquired in development of real biotelemetric system using off the shelf embedded hardware technology, namely ARM microcontrollers, FRAM memory and dedicated ZigBee chipsets with emphasis on reliability and security of data transfer.

Devices participating in biotelemetric system use Zig- Bee and Ethernet networks as underlying structure for secure and reliable data communication.

Energy Availability Forecasting for Harvesting-aware Wireless Sensor Networks: Analysis of Energy Demand of a Predictor Based on Evolutionary Fuzzy Rules

Environmental monitoring sensor networks often operate in remote locations and thus must be designed for energy-efficiency and reliability. The first goal of energy efficiency can be achieved through low-power design of the monitoring hardware, often supplemented by energy management schemes of varying complexity and sophistication. In case of sensor nodes endowed with energy-harvesting capabilities, the energy management systems can take advantage of harvesting outlook that can take the form of prediction of energy available for harvest in the near future. When designing such sophisticated prediction and management schemes, it is important to consider the energy cost of gathering the predictor data and executing the forecasting algorithm. This contribution describes the results of experiments designed to assess the energy required to run a recently introduced energy-availability forecasting algorithm based on evolutionary fuzzy rules. In particular, it presents an analysis of experiments conducted using several hardware platforms typically used to implement the computational core of environmental sensor nodes. The results clearly show the advantages of using modern low-power, 32-bit hardware platforms. In addition, they demonstrate the advantages of support for floating point operations, as well the importance of embedded code optimization to maximize the benefits of the modern microcontroller units.

This article describes the conceptual proposal of measuring erosion of rock formations using protection networks. It outlines the concept of two types of wireless sensors of a steel retaining network tension and a data concentrator unit, which cyclically reads the measured data from these wireless sensors.
