This paper aims to present an overview of the Smart HEMS and Smart heating technologies and trends. It highlights a) Objectives and results of R&D projects in the Smart Home field; b) Smart Home Energy Management Systems (Smart HEMS); c) Smart thermostat products existing on the market and scientific approaches which deal with advanced control of heating systems, more specifically the prediction...
This paper propose a second-order sliding-mode observer for sensorless control of a permanent magnet synchronous motor. The corresponding observer is used to estimate the rotor speed. Simulation results are shown to confirm the effectiveness of the proposed method.
In this article, we present a study based on the application of the new approach of the vectors of Park in the two axes ropers to the detection of the defects of bars in the three-phase induction machines. In order to simulate the behavior of the motor with defect, we propose the modeling of the diagram multi windings of the induction motor allowing apprehending his behavior in presence or absence...
This project deals with technical assistance for people of reduced mobility. The goal of this work is to have a mobile platform with an embedded prehensive arm (MANUS®) track a wheelchair. The use of this mobile unit in relation to the patient’s wheelchair is carried out on a master-slave basis. This study, therefore, has a plural-disciplinary nature: Science for the Engineer, Human, Social and Clinical...
In this paper, we deal with an original advanced driver assistance system (ADAS) based on the use of omnidirectional vision and an evidential fusion architecture. The panoramic perception solution permits us to address efficiently the problem of close vehicles detection but also the monitoring side traffic system. The fusion and integration of this sensorial data stream is assumed by a credibilist...
This paper deals with the design of a robotic platform providing a grasping procedure to assist disabled persons. Like most of the vision-based systems, the camera used to guide the arm toward the object is embedded onto the gripper, which gives a very local view of the environment. We propose to use a catadioptric sensor in order to deal with situations where the object of interest is out of the...
This project deals with technical assistance for people of reduced mobility. We propose to study the technical of an original approach, which consists of mounting a prehensile arm onto a mobile base. The use of this mobile unit in relation to the patientpsilas wheelchair is carried out on a master-slave basis.. To ensure the tracking of the wheelchair by the mobile platform, we will present and compare...
In the sensor-based applications context, sensor reliability is not always taken into account. Due to the uncertain nature of sensors, we must integrate to the problem of belief attached to the sensors data. This paper deals with the dysfunction detection based on a two-level approach. The first level extracts conflict information of the combination of multiple data sources. The second level is based...
This article deals with a target tracking application for the disabled. The objective of this work is to track a wheelchair with a mobile platform and an embedded grasping arm (MANUS). We propose an approach based on an association of two Kalman filtering levels. The first level permits an estimation of the wheelchair configuration. The second is used to compute the mobile platform configuration in...
Firstly this article presents a multi-level architecture permitting the localization of a mobile platform and secondly an incremental construction of the environment's map. The environment will be modeled by an occupancy grid built with information provided by the stereovision system situated on the platform. The reliability of these data is introduced to the grid by the propagation of uncertainties...
This paper deals with a context awareness system based on a service-oriented architecture dedicated to the Smart Home. In our approach, a Smart Home must be able to provide services adapted to the needs of its inhabitants. To achieve this, we propose to build a Smart environment that takes into account the ambient context of its inhabitants, providing contextually-aware services. In previous work...
This article concerns road safety and driving assistance. To solve this problem, we propose a data fusion architecture based on the Dempster-Shafer theory. This multilevel approach allows the management of complementary and redundant data which come from two perception systems: an omnidirectional vision sensor and a laser telemeter. The originality of this architecture is its ability to manage and...
This article deals the problem of data fusion applied to road safety by proposing a solution based on a multi-level approach allowing the exploitation of additional and redundant data which emanate from two systems of perception: an omnidirectional vision sensor and a rangefinder laser. The first part concerns the processing of sensory data stemming from both sensors allowing the extraction of primitives...
In this paper we will talk about the smart home concept. Even if smart home domain is not like the robotics domain, we can notice resemblances. In V. Ricquebourg et al. (2005), we shown that a smart home can be seen as a robot that turn over itself. A robot needs sensors to discover its environment. In the same way, a smart home needs sensors to watch in itself. This paper deals with a service oriented...
In this paper, we propose an application of the perceptual organization based on the Dempster-Shafer theory. This method is divided into two parts which respectively rectifies the segmentation mistakes by restoring the coherence of the segments and detects objects in the scene by forming groups of primitives.We show how we apply the Dempster-Shafer theory, usually used in data fusion, in order to...
