Abstract: A method for activating a vehicle function, by an activation device including a transceiver to communicate with “hands-free” access equipment. The transceiver is equipped with a gyroscope and a magnetometer and two receiving antennas that have a coefficient of electromagnetic coupling between them that is below a threshold. The method includes the following steps for at least two consecutive footsteps: transmission of a signal comprising data of the gyroscope and the magnetometer of the “hands-free” equipment to the vehicle; comparison of the data with representative values of the gyroscope and the magnetometer of the transceiver; determination of a first direction of the user; determination of a second direction of the user based on an estimation of a first angle of arrival of the signal towards the transceiver; comparison of the first direction and the second direction; activation of the vehicle function on the basis of the result of the comparison.

Abstract: A method for location of a beacon includes: executing R sequences, wherein R is a whole number equal to or greater than 2, each including reception by a first antenna network and a second antenna network of a signal originating from the beacon, wherein the signals of the R sequences are of different wavelengths; calculating a first estimation function for angles of arrival of the signal on the first antenna network and of a second estimation function for angles of arrival of the signal on the second antenna network; and executing a mutual correlation of the R first estimation functions and the R second estimation functions, for the respective determination of a first angle between the beacon and the first network, and of a second angle between the beacon and the second network.

Abstract: Described herein are one or more apparatus, that at least partially synchronize with a first radio-frequency signal from a first antenna element, of an array of spatially distributed antenna elements in a multi-antenna array receiver, to determine the position of at least one of a repeated guard interval in the first radio-frequency signal from the first antenna element, the repeat occurring at a particular defined characteristic interval. The apparatus then use the determined position of the at least one guard interval in the first radio-frequency signal to switch to a second radio-frequency signal from a second antenna element, of the array of spatially distributed antenna elements in a multi-antenna receiver, and further determine a relative orientation of the multi-antenna receiver from a transmitter of the radio-frequency signals using characteristics determined for the first and second radio-frequency signals following the at least respective partial synchronizations.
