ABSTRACT:
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.
