Abstract: The invention uses the advanced intelligent network to provide caller identification for calls placed over the internet (24). A long distance call placed with an internet carrier results in the originating SSP (14) forwarding the call to an originating POP (22) for the internet carrier. The caller ID information is routed through the signaling system 7 network (16) to the SSP (32) in the terminating network. The call is routed to a terminating POP (26) and then to the SSP (32) in the terminating network. The SSP (32) inserts the caller ID information received through the SS7 network (16) and routes the call to the terminating line (30).

Abstract: An automatic garage door system includes a controller. The controller receives information on the vehicle's position from a vehicle parking unit. When the automatic system is on, the system determines if the garage door is open via a garage door position sensor. When the garage door is open, the controller signals a remote interface unit located inside the house to indicate that the garage door is open. The vehicle parking unit determines if a car is entering or leaving the garage. When no vehicle is entering or leaving the garage, the garage door is automatically closed after a predetermined time interval. When a vehicle is entering the garage, the vehicle's position is monitored by the vehicle parking unit, which displays the vehicle position information to the vehicle driver with a visual parking indicator.
