Standby modes to minimise consumption and startup time

A piece of equipment comprising at least one sensor, at least one first component and at least one second component which is quicker to start up than the at least one first component, the piece of equipment being arranged to operate according to at least:

• one first standby mode, wherein at least one first sensor is switched on, the at least one first component and the at least one second component not being switched on, the piece of equipment implementing a first detection function to detect a presence of a user by using the at least one first sensor;
• one second standby mode, wherein at least one second sensor, which is identical or not to the at least one first sensor, is switched on, the at least one first component and the at least one second component not being switched on, the piece of equipment implementing a second detection function to detect the presence of the user, more accurate and more consuming than the first detection function, by using the at least one second sensor;
• one third standby mode, wherein the at least one first component is switched on and the at least one second component is not switched on;
• one active mode, wherein the at least one first component and the at least one second component are switched on.
