Patent number: 11194011Abstract: The invention relates to a device for transmitting an ultra-wideband-type signal, the signal including, one after the other temporally, a synchronization header and a data payload field. The transmission device includes a first generator to generate first synchronization header symbols and a third generator to generate third data payload symbols. The transmission device further includes a time sequencing device for sequencing the first and third symbols in a sequence of symbols, successively including the first symbols in the synchronization header and the third symbols in the data payload field. The transmission device further includes at least one antenna, capable of transmitting the signal including the sequence. The transmission device additionally includes a fourth generator to generate at least one fourth secret symbol, the time sequencing device being configured to insert the at least one fourth secret symbol into the sequence of symbols.Type: GrantFiled: February 1, 2017Date of Patent: December 7, 2021Assignee: BlinksightInventors: Stéphane Mutz, Matthieu Mutz

Publication number: 20200389866Abstract: The invention relates to a relative localization device comprising at least three nodes separated from each other. The node (A) being able to: trigger a round-trip message exchange (M1, M2) with a node (B); calculate a travel time (Tab) of the message (M1, M2); and emit a message (M5) containing an information (INF1) indicating the travel time (Tab). The node (C) being able to: trigger an exchange of messages (M3, M4) with node A for calculation of a travel time (Tac) of the message (M3, M4); receive the messages (M1, M2, M5); measure receive times (T1, T2) of the messages (M1, M2); and calculate a travel time (Tbc) of the message (M2) from the node (B) to the node (C) from the times (T1, T2), the time (Tac) and the information (INF1), contained in the message (M5).Type: ApplicationFiled: April 13, 2017Publication date: December 10, 2020Applicant: BlinksightInventors: Stéphane MUTZ, Matthieu MUTZ
