A system for the secure physical attachment of a second device to a first device
is disclosed comprising a first and second inter-connection attachment means in
physical association with each device. The second inter-connection attachment means
physically mates with its corresponding first inter-connection attachment means.
Additionally, means for detecting the physical mating of each of the first and
second inter-connection attachment means is provided. The detecting means is preferably
associated with at least one of the devices and in communication with each of it's
associated device's inter-connection attachment means. Means are provided for determining
that the first and second inter-connection attachment means have been securely
mated and, if not, means are provided for indicating the status of the completion
of the secure attachment there between. A controller is used for halting at least
one of the devices in the event that the attachment there between has not been
secured and for receiving additional instructions from an end-user.
