Patent ID: 8818258

Claim:
A geographically-based information distribution system comprising: a first mobile unit position receiver attached to a first mobile unit, wherein the first mobile unit position receiver wirelessly receives first mobile unit position information representing the first mobile unit position; a first mobile unit position transmitter attached to the first mobile unit, wherein the first mobile unit position transmitter transmits the first mobile unit position information; a second mobile unit position receiver attached to a second mobile unit, wherein the second mobile unit position receiver wirelessly receives second mobile unit position information representing the second mobile unit position; a second mobile unit position transmitter attached to the second mobile unit, wherein the second mobile unit position transmitter transmits the second mobile unit position information; a processing unit comprising a processing unit receiver and a processing unit transmitter, wherein the processing unit includes as inputs the first mobile unit position information that is received from the first mobile unit position transmitter and the second mobile unit position information that is received from the second mobile unit position transmitter, and wherein the processing unit is configured to: periodically identify first segments in a database, the first segments being associated with a first geographical zone that includes the first mobile unit position; select, after a predetermined period of time, first selected segments of the first segments, wherein the first selected segments are selected by the processing unit based at least in part upon priority information associated with each of the first segments that determines how often the first segments are displayed; transmit the first selected segments to the first mobile unit using the processing unit transmitter; periodically identify second segments in the database, the second segments being associated with a second geographical zone that includes the second mobile unit position; select, after a predetermined period of time, second selected segments of the second segments, wherein the second selected segments are selected by the processor based at least in part upon priority information associated with each of the second segments that determines how often the second segments are displayed; transmit the second selected segments to the second mobile unit using the processing unit transmitter; and at least one display configured to display the first selected segments transmitted by the processing unit transmitter.
