Abstract: An accidental tumbling monitoring method, system and a terminal are disclosed. When a human wearing intelligent shoes is in an accidental tumbling state, whether or not a first inclination angle of soles of the intelligent shoes is restored to a preset inclination range within a first preset time range is determined. If the human tumbles seriously, positioning information of the human wearing the intelligent shoes is sent to a guardian, whether or not a monitoring platform receives feedback information from the guardian within a second preset time range is determined, if not, the monitoring platform sends first aid information of the human wearing the intelligent shoes to an emergency center, and therefore, the situation that the human wearing the intelligent shoes has an accident due to belated treatment is avoided.

Abstract: A localization scheme and method using a laser sensor for indoor wheeled mobile robots (IWMR), which need to localize themselves for working autonomously, is provided. In this method, a laser sensor moves inside an onboard guide way and its distance measurements are used to robustly detect and recognize a unique target based on edge detection and pattern recognition techniques. From the distance measurements with respect to the recognized target, a kinematic model is developed to determine the IWMR orientation and location in the global co-ordinates (in 2-D). Such target recognition and localization methods are validated with experimental results.

Abstract: A method of modeling a diesel engine that is capable of multiple combustion modes and equipped with a turbocharger and EGR loop. The model comprises a set of equations, each equation representing one of the following as a time derivative: pressure at the intake manifold, pressure between the turbine and an intake manifold throttle, pressure at the exhaust manifold, the compressor power, and the fresh air fraction (the ratio of fresh air to EGR). The model is used to determine what engine conditions (such as throttle positions and turbocharger output) will result in desired pressures and fresh air fraction.

Abstract: A method of controlling a diesel engine that is capable of multiple combustion modes and equipped with a turbocharger and EGR loop. The control method avoids a singularity condition inherent in turbocharged diesel engine having multiple combustion modes. For different combustion modes, different system states, control variables, and actuators are carefully chosen for different controllers based on the characteristics of the corresponding combustion mode as well as sensor and measurement limitations.
