Could we have some context please? Do you know which of several possible definitions of 'contact' are applicable? With what do you think the contact is associated? This site deals with the tools associated with factory automation. Within that context, what common tool associates with the term 'Contact'?
If I said that the definition was "an encounter with an alien intelligence that has been registered with and investigated by the International Registry of Pseudoscientific Phenomena (IRPP)", would that be helpful?
