Landmine and improvised explosive (IED) are the major threat to the occupants inside armored vehicles. IED-detonation introduced Global effects of severe acceleration can greatly hurt vehicle occupants. To investigate the responses of armored vehicle and its occupants subjected to landmine explosion, an low-cost equivalent miniature model of the vehicle replacing real-scale one was built. With a full...
measuring micron particle density becomes challenged in a high concentration level. To address this issue, we proposed ultrasonic attenuation to measure high concentration micron particles of cement powder in gas-solid two phase flow. An ultrasonic inspection system and a particulate matter concentrations simulation chamber were built respectively to demonstrate relationship between signal attenuation...

The problem of estimating speaker location in smart conference video system is considered. In this paper, a four-microphone cross array is constructed to localize speakers with Time Difference of Arrival (TDoA) measurements based on hyperbola model. The time delay was calculated using Generalized Cross Correlation (GCC)algorithm. A practical test system was build to confirm the feasibility of the...
Visualization of real-time logistics monitoring microsystem is designed based on STM32, which is high ability, low power consumption and low cost. The acceleration acquisition module, the temperature and humidity acquisition module, the TFTLCD module, the memory module and the radio frequency identification (RFID) module are integrated in the intelligent microsystem. In the process of transportation,...
Several Prognostics and Health Management (PHM) algorithms are to be analyzed in this paper, and the purpose is set to master the know-how of the optimization of the prognostic algorithms. To implement the PHM for sensitive cargo transportation, based on the original data collected during the dedicated tests, applying the microsystem hardware designed and assembled by the research team, as well as...
