The current paper represents a portable battery powered system which is capable to measure and analyze the data from different type of sensor data like humidity, air pollution gases, dust, smoke, etc. and send it via Bluetooth or GSM/GPRS connection to the remote devices. It contains GPRS modem with integrated Bluetooth module, integrated chip antenna, power management module, rechargeable Li-Ion...
The current paper describes an innovative navigation system based on GPS receiver and high speed 9 DoF IMU based on MEMS inertial sensors (3D linear accelerometer and 3D magnetometer and 3D gyroscope) which accomplishes the real-time read of the navigation and inertial data and write to FLASH memory. Also the system may transmit the data by Bluetooth or GPRS modem connected externally to the remote...
The paper represents an innovative miniature 9DoF IMU system based on MEMS digital output inertial sensors which may read the linear and angular rate accelerations and the magnetic field at all three axes, the temperature up and down of the board by integrated analog and digital sensors and transmits the measured data by Bluetooth or GPRS link to the remote servers or devices. The integrated Bluetooth...
This paper discusses the estimation of the decomposition parameters of the liquid–gas-steam system, which is produced by the hydrogen peroxide decomposition at isobar conditions. The thermodynamic analysis calculates the two critical concentrations, which mark the phase transitions of the system depending on the initial pressure and hydrogen peroxide concentration.
