Today, medical simulators are increasingly gaining appeal in clinical settings. In obstetrics childbirth simulators provide a training and research tool for comparing various techniques that use obstetrical instruments or validating new methods. Especially in the case of difficult deliveries, the use of obstetrical instruments-such as forceps, spatulas, and(More)
BACKGROUND In obstetrics, manipulations are mainly learned during real deliveries. To minimize the risks linked to such training, we propose a childbirth simulator as a teaching tool in hospitals. More specifically, we focus on training with forceps during obstetric manipulation. METHODS The training method can be divided into two steps: the teaching of(More)
Precise and realistic models of outdoor environments such as cities and roads are useful for various applications. In order to do so, geometry and photography of environments must be captured. We present in this paper a coupled system, based on a fish-eye lens CCD camera and a laser range scanner, aimed at capturing color and geometry in this context. To(More)
The aim of this paper is to propose efficient multivariables controllers for an electropneumatic system. The considered system use two three-way proportional servodistributors. Generally, it is supposed that these two servodistributors are equivalent to one five-way proportional servodistributor when they are controlled with inputs of opposite signs. In(More)
We present a new Mobile Mapping System mounted on a vehicle to reconstruct outdoor environment in real time. The scanning system is based on two sensors, a laser range finder and a camera equipped with a wide-angle fisheye lens. We can produce 3D coloured points or 3D textured triangulated models of the nearby environment of the vehicle. We explain our(More)
This paper presents some new automatic procedures for the BirthSIM childbirth simulator. BirthSIM is able to simulate the uterine contractions and the mother's voluntary efforts, this enables the operator to synchronize these two types of efforts during a normal childbirth, or to synchronize these two efforts with the operator's tractive instrumental effort(More)
Electropneumatic actuators are more and more used in industrial applications. Due to nonlinear phenomena, for many applications, high accuracy can only be obtained when using nonlinear control laws. These strategies allow to get high performances but often need the knowledge of all state variables. Then, there is a real interest to design observers in order(More)
