The article describes problems of determining the type and automatic sorting of household waste using mobile computing devices. All of the required hardware and partially software, required for implementation of this service, are already present in modern smartphones.
In the paper, the digital compass based on AVR microcontroller has been developed using MEMS accelerometer-magnetometer LSM303DLHC. The structure and hardware of the digital compass have been developed. The calibration algorithms of the accelerometer and magnetometer of the LSM303DLHC module have been described. The calculation algorithm of the pitch and roll angles has been described. The heading calculation algorithm of the digital compass without tilt compensation and with tilt compensation has been described.
The paper proposes a new generalized accelerometer model and input parameters identification graph for solving technological processes design automation problem.
In this work we consider sensing elements of an accelerometer which is made using the combined technologies of silicon-on-insulator (SOI) structures and silicon nanocrystals whiskers manufacturing. On their basis a quick-response, high sensitive to acceleration and displacement device with submicrometer and nanometer typological sizes has been designed.
Purpose – to organize a temporary network of seismic observation tool for continuous collection of information on seismic events in the area of the Zaporizhzhya NPP. Methods. In the bomb shelter in the territory dispensary Zaporizhzhya NPP, organized a temporary observation points to maintain a register of certified seismometer seismic events GURALP CMG-40TD. Choosing a place for the installation of temporary seismic observation point due to occurrence of bedrock in this place at least in the area ZAES depth (about 8 m).
