Abstract: In some embodiments, a device for determining a speed of rotation of an object includes a visualization device fastened to the object. A lighting device is configured to light the visualization device by light pulses of adjustable frequency. An adjustment device is configured to adjust a frequency of the light pulses so that the visualization device appears immobile when the object is in rotation. A processor is configured to determine the speed of rotation based on the adjusted frequency.

Abstract: An embodiment method for controlling a physical object to be shared by several potential users and in an enclosure in an open state or in a closed state includes detecting a presence or an absence of the object in the enclosure in the closed state via a first wireless link between the object and a reader situated in the enclosure, the first wireless link being contained in the enclosure in the closed state. The method also includes transmitting a first information item representative of the presence or of the absence of the object in the enclosure to a computer server via a second link and an internet network, the computer server being accessible via a website configured to be managed by an administrator.
