ABSTRACT:
BACKGROUND OF THE INVENTION
Since the early 1990's the National Weather Service (NWS) has been broadcasting digitized weather warning header information concerning the nature and scope of the content of the alert message following the header. The digitized header is transmitted in a special AFSK data format, called Specific Area Message Encoding (SAME). SAME is a subset of the Emergency Alert System (EAS) as defined in Part 11 of the FCC rules set out in the United States Code of Federal Regulations.
This system uses specific ASCII character event codes for data fields such as severe weather events, geographic area of the alert time etc. Sophisticated receivers and decoders are required to recover and decode the digital header information.
A number of patents have been granted on various aspects of the SAME system including U.S. Pat. No. 5,548,323 to Callahan; U.S. Pat. No. 5,917,887 to Fesler; U.S. Pat. No. 5,995,553 to Crandall; and B1 U.S. Pat. No. 5,121,430 to Ganzer. Other emergency alert decoding schemes were disclosed in Martinez, patent U.S. Pat. No. 4,415,771.
Alphanumeric paging, alphanumeric paging terminals, the activation of alphanumeric paging thorough alphanumeric paging terminals by alarm systems, automatic alphanumeric paging of weather, and the activation of alarm systems by decoded alert signals are all known in the art.
Examples of premise alarm systems reporting alarm status to a central station are taught by U.S. Pat. No. 4,141,006 to Braxton; U.S. Pat. No. 3,523,162 to Streit; U.S. Pat. No. 3,761,914 to Hardy et al.; U.S. Pat. No. 3,686,654 to Judlowe; U.S. Pat. No. 3,714,646 to Nurnberg et al.; U.S. Pat. No. 3,855,590 to Neuner and U.S. Pat. No. 3,855,456 to Summers et al.
SUMMARY OF THE INVENTION
At least three major problems have been found in the current state of the art with SAME decoding methods. The first being SAME is technically difficult to decode because of its engineering design scheme. There are many reason why a SAME message might not decode. The user will usually not know the reason that the message did not decode thereby preventing the undertaking of corrective procedures.
The second major problem is that there are numerous different applications for the decoded message, which change over time due to individual need and law changes, and the user has no easy way of customizing the output of the alert message format to optimize system performance for his particular needs.
A third major problem is having an easy way to forward the decoded and translated SAME message to other communications systems such as PCS, email, LED sign boards and alphanumeric paging.
This invention addresses these problems by teaching a method and apparatus using LED's, non volatile memory, an LCD, microcontrollers and a keypad to quickly determine the decoding status of EAS and SAME messages; a method and apparatus for the user to define the translation of these messages into custom text messages, abbreviations and different languages; and an efficient method and apparatus for interfacing the decoded messages to alphanumeric paging, personal communication text messaging services, internet, email and remote LED signboards through modems and alphanumeric paging terminals.
