Abstract: A method is described for locating an electronic device in the vicinity of an array having a central unit and anchors connected to the central unit. The method is applied during at least a communication cycle comprising a plurality of time slots each allocated to a distinct anchor. The method involves receiving an initiation signal from the electronic device, performing an election of a set of anchor(s) based on the reception quality of the initiation signal, emitting a reply signal during a respective allocated time slot, operating the electronic device in a first configuration during the time slots which are not allocated to one of the anchors the elected set, operating the electronic device in a second configuration during the time slot allocated to the elected set to detect and receive a reply signal, and calculating a location of the electronic device based on the reply signal.

Abstract: The invention relates to a method implemented by a vehicle UWB system including at least two UWB sensors, with a view to determining a zone in which a UWB device is located among a predetermined set of zones, by applying a function dependent on a set of physical quantities. The function comprises one or more generalized linear models. The method comprises, by each respective UWB sensor, a measurement with a view to obtaining a measured value of the respective physical quantity. The method comprises, for each generalized linear model comprising at least one physical quantity for which the measurement failed, and for each physical quantity for which the measurement failed, determination of a replacement value of the physical quantity for application of the generalized linear model. The method improves localization of the UWB device.

Abstract: A system for detecting an intent to open a hatch of a vehicle includes an identifier having means for recording the intent to open a hatch, where the identifier authenticates itself with an electronic control unit, and receives from the ECU a request for confirmation of intent to open a hatch. Following receipt of the request for confirmation of intent to open a hatch, the existence of a command confirming intent to open a hatch in a memory in the identifier is verified. When the command is initiated, a command signal is sent corresponding to the command confirming intention to open a hatch. The electronic control unit is integrated in the vehicle and authenticates the identifier, locates the identifier in proximity to the hatch, sends the request for confirmation of intent to open a hatch, and receives the command signal corresponding to the command confirming intent to open a hatch.

Abstract: An analysis device for analyzing a passenger compartment of a vehicle to detect persons is disclosed. The device has at least one ultra-wideband transceiver configured to transmit a signal (S1) on a wireless communication channel, at least one ultra-wideband transceiver configured to receive a signal (S2) corresponding to the transmitted signal (S1), to compute at least one impulse response (CIR) of the wireless communication channel from said received signal (S2), and to transmit said at least one impulse response (CIR) of the wireless communication channel to an electronic control unit. The electronic control unit is configured to determine biometric features (B) and/or volumetric occupancy features (P) of the passenger compartment on the basis of said at least one impulse response (CIR) of the wireless communication channel.
