Methods and apparatus for monitoring electrical contacts comprising measuring a first voltage across a connection between a device and a base, charging a power source in the device, measuring a second voltage across the connection, determining a difference between the first voltage and the second voltage and initiating a signal alarm if the difference is greater than a predetermined threshold value. The device may be maintained by a management system.

La présente invention concerne des procédés et un appareil qui permettent de surveiller des contacts électriques. Le procédé consiste à mesurer une première tension au niveau d'une connexion entre un dispositif et une base, à charger une source de puissance du dispositif, à mesurer une deuxième tension au niveau de la connexion, à déterminer une différence entre les première et deuxième tensions et à déclencher un signal d'alarme si la différence dépasse une valeur limite prédéterminée. Le dispositif peut être pris en charge par un système de gestion.
