Abstract
Electronic device formed by two separate units of which at least one emits electromagnetic waves; based on the intensity of the electromagnetic waves detected, the second unit determines the relative distance between the two units. When this distance is greater than a predetermined value, at least one of the two units emits a signal, optical and/or acoustic, able to attract the attention of persons. The device is susceptible of application to send an alarm in event of excessive distance, fraudulent or inadvertent, of an item of property, such as suitcase, purse, photographic apparatus. <IMAGE>
