Abstract: The present invention integrates data from multiple outside sources for the purpose of managing the closing, funding, and audit of a real property transaction using a secure, computer network, such as an internet-based network, and graphic user interface(s), thereby allowing permitted users to import, update, verify, view, and control transaction information. Permitted users can electronically communicate and view the transaction data during the process of the real property transaction. An Internet-based computer system may execute one or more computer program products for providing secured data input, data input screens, and data import capability, and sequencing an approval of data input by the permitted users.

Abstract: A system for providing early warning of the approach and egress of emergency vehicles in which the warning system provides a display to indicate the direction from which the emergency vehicle is approaching and in addition provides preemption control of the traffic signals at an intersection. A transmitter mounted on an emergency vehicle transmits a signal whenever it is on an emergency call which is received by infrared (I.R.) receivers positioned at an intersection to respond to the transmitted signals. The received signal is then processed by a master controller which in turn pre-empts operation of traffic signals to control traffic flow at the intersection to which the emergency vehicle is approaching. The master controller also provides an output to display signs facing approaching traffic on each road approaching the intersection which displays messages and symbols indicating the direction of the approaching emergency vehicle.
