How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
In this paper, a less than $200 artificial ventilator that can be used against COVID-19 pandemic is presented. Using low-cost easyto-find materials, it has been designed for helping developing countries where supplies for building new medical equipments are limited. It complies with medical requirements, allowing to monitor and adjust ventilation p...
Cetacean monitoring is key to their protection. Understanding their behavior relies on multi-channel and high-sampling-rate underwater acoustic recordings for identifying and tracking them in a passive way. However, a lot of energy and data storage is required, requiring frequent human maintenance operations. To cope with these constraints, an ultr...
In this paper, an ultra-low power embedded unsupervised learning smart vibration sensor is proposed for automatic industrial monitoring and fault detection. Using K-means algorithm, it is able to detect abnormal vibrations patterns. Architecture of the system is first presented, then embedded processing algorithms composed of feature extraction and...
This paper presents a mixed analog-digital always-on ultra low-power wake-up based on pulse pattern analysis. It is used for triggering a high performance multi-channel recorder only when necessary. Its architecture makes the most of ultra-low power analog primitives coupled with an embedded digital low power system for fine tuning the pulse detect...
Acoustic monitoring is a key feature for studying biodiversity. Recent works on very high frequency animal sounds open new insights and challenges on biodiversity survey. In order to set a scaled monitoring, and to cover most of the frequencies of the present species, a novel multi-channel ultra high velocity recorder has been designed, called Qual...
Reluctance coil guns are electromagnetic launchers having a good ratio of energy transmitted to actuator volume, making them a good choice for propelling objects with a limited actuator space. In this paper, we focus on an application, which is launching real size soccer balls with a size constrained robot. As the size of the actuator cannot be inc...
Robot Club Toulon Middle-size league (MSL) team is a new team aiming at participating in the RoboCup 2020. For our second participation, our robots have been entirely redesigned. This paper explains the major changes in our robots, and focus on changes that have not been tested yet by the MSL RoboCup community.
