US7,130,389
Title:Digital notification and response system
Filing Date:2005.4.28.
Issue Date:2006.10.31.
Abstract:
A digital notification and response system utilizes an administrator interface to transmit a message from an administrator to a user contact device. The system comprises a dynamic information database that includes user contact data, priority information, and response data. The administrator initiates distribution of the message based upon grouping information, priority information, and the priority order. The message is transmitted through at least two industry standard gateways simultaneously to groups of user contact devices based upon priority information. Once the message is received by the user contact device, the user contact device transmits a response through the industry standard gateways back to the dynamic information database.
