Mobile weather band radio and method
DCFirst Claim
1. A radio with dynamic geographic message updating, said radio comprising:
- a radio receiver for receiving broadcast radio signals containing a message and a corresponding geographic identifier;
a device for determining a current position of the radio;
geographic identifiers and electronic map data defining geographic regions corresponding to said geographic identifiers; and
a controller processing the determined current position to determine one of said geographic identifiers corresponding to the determined current position, said controller further performing an operation in response to said message when said received geographic identifier corresponds to said determined geographic identifier.

Abstract
A mobile weather band radio and method with dynamic geographic message updating. The radio has a weather band tuner for receiving weather band signals containing a message and a geographic identification code. A position indicative receiver is provided for receiving position indicative signals and determining a current position of the radio. Geographic identification codes and electronic map data are stored in memory for defining geographic regions corresponding to the geographic identification codes. A controller determines one of the geographic codes corresponding to the determined current position based on the position indicative signals, and further performs an operation, such as playing the message, when the determined geographic code corresponds to the received geographic code.

18. A mobile weather band radio with dynamic geographic message updating, said radio comprising:
-
a radio receiver for receiving weather band signals containing a message and geographic identifier;
a position indicative receiver for receiving position indicative signals and determining a current position of said radio;
memory storing geographic identifiers and electronic map data defining geographic regions corresponding to said stored geographic identifiers; and
a controller processing the determined current position to determine one of said geographic identifiers corresponding to the determined current position, said controller generating an alert signal in response to said message when the determined geographic identifier corresponds to said received geographic identifier. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method for providing radio messages with dynamic geographic updating, said method comprising the steps of:
-
determining a current position;
comparing said current position with electronically stored map data and determining which one of a plurality of geographic regions said current position is located within;
receiving a radio wave signal containing a message and a geographic identifier;
comparing the determined geographic identifier defined by said position indicative signal with said received geographic identifier and determining whether said determined geographic identifier corresponds to said received geographic identifier; and
performing an operation if said determined geographic identifier corresponds to said received geographic identifier. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
