The member for controlling the device is capable of triggering, once the second transceiver of the device has received the signal, the transmission of a signal to a wireless radio receiver supported by the portable object, and comprises a control member for triggering, when the wireless radio receiver has received the second signal, the transmission of a signal, the control member being connected to a calculator member for computing a distance between the portable object and the device using the signals, the portable object comprising a member for independently powering the transmission member, the receiver and the control member thereof. The device comprises a further calculator member for computing an incoming angle of the first signal and/or the third signal such as to trigger, when the angle is within a given angular range and when the distance is lower than a predetermined value, the unlocking of the machine and to trigger, when the distance is higher than a predetermined value, the locking of the machine."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and method for controlling access to at least one machine","description":"The invention relates to a device for controlling access to a machine, comprising a portable object having a signal transmission member and a device for locking and unlocking a machine.
