Publication number: 20160301449Abstract: A device (200) for locating mobile elements provided with at least one standard NFC tag. The location device (200) includes transmission elements (215) for transmitting a signal to query the at least one tag, monitoring elements (205, 245) and a plurality of receiving elements (225) selectively connected to the monitoring elements, the receiving elements being receptive to the querying signal and to a response signal from the at least one tag. The monitoring elements are configured so as to measure in sequence signals from receiving elements connected to the monitoring elements and to estimate the position of the at least one tag by interpolating measurements.Type: ApplicationFiled: November 18, 2014Publication date: October 13, 2016Applicant: EPAWNInventors: Valentin LEFEVRE, Laurent CHABIN, Christophe DUTEIL

Patent number: 8923885Abstract: The subject of the invention is in particular the real-time interfacing of a plurality of mobile elements with a computing system. After having selected at least one location module integrated into a mobile element, the at least one location module is activated sequentially. At least one signal is then received from the at least one activated location module and at least one item of information relating to the position of the mobile element including the at least one activated location module is calculated in real time on the basis of the at least one signal received. A single location module may be activated at a given instant.Type: GrantFiled: September 2, 2011Date of Patent: December 30, 2014Assignee: EpawnInventors: Valentin Lefevre, Christophe Duteil
