Population aging has become a worldwide problem. Fall accidents are considered as one of the major health risks, especially for elderly people. Fall detection devices are the key to distinguish a fall from daily activities, automatically alert when a fall occurred and significantly decrease the time of rescue when the monitored patient falls down. The proposed prototype is composed of a tri-axial...
Large ADS-B surveillance area and WAM are distributed systems composed by sensors that are spread out on the targeted surveillance area. These sensors create a large network of unmanned devices installed almost everywhere: control towers, buildings, utility poles, etc. The sensors setup, maintenance and obsolescence are serious cost project pitfalls; therefore maintenance, cost reduction of obsolescence...
Many embedded real-time applications are typically time-triggered and preemptive schedulers are used to execute tasks of such applications. Orthogonally, composable partitioned embedded platforms use preemptive time-division multiplexing mechanism to isolate applications. Existing composable systems that support two-level scheduling are restricted to cooperative intra-application schedulers, and thus...

The hardware is based on FPGA and described through VHDL, aiming flexibility of prototyping and feasibility of...
Increasingly embedded devices are turning to two technologies to achieve high performance and enable efficient programmability as well as product usability. The first is multi-core processing on FPGA devices in which the multi-core architecture allows software to map application-level parallelism to inherent parallel fabric to offer better performance, the re-configurability leads to flexible and...
We developed Autonomous Buoy, which is composed of embedded system, OPC (Optical Particle Counter) and CTD (Conductivity, Temperature, Depth) sensors, to observe underwater environment. The vehicle is an autonomous profiling float that uses a buoyancy engine to cycle horizontally while moving up and down. The autonomous buoy is controlled by embedded system composed of field-programmable gate array...
Recently, there has been a need of small size UAV for vast applications in military and civilian applications as local area surveillance reconnaissance in hostile condition, damage assessment in natural disaster and remote sensing of harmful materials. UAV can finish missions without risking human life. However, applying low-cost sensors for flight control is of extreme challenge due to less accuracy...
