When the base is assembled with the assembling interface, the second transmission terminal group is electrically connected with the first transmission terminal group.

A resident information box system incorporating the installation of call boxes within each apartment structured and arranged to be linked to a single phone number for delivering messages from management, without having to waste natural resources, like paper and electricity, as well as the time and effort of the management staff.

A mobile phone station and cellphone application cooperating to provide the complete mobility expected of a cellphone and yet provide a complete desktop experience. In a fully wireless embodiment, the mobile phone station and cellphone application cooperate to automatically connect the cellphone to a Miracast monitor without requiring user operations. After performing initial pairing operations and monitor selection, when the cellphone meets selected criteria, such as the cellphone wirelessly charging or the cellphone within Bluetooth range and autoconnection is selected, the mobile phone station directs the cellphone to automatically start Miracast operations and connect to a selected monitor. In one embodiment, the user simply places the cellphone on the wireless charging pad and the desktop environment is activated. When the user wishes to leave, the user simply picks up the cellphone and walks away, the environment connections ceasing when Bluetooth reception ends.
