Electronic sign for information equipped for satellite positioning system on passenger transportation vehicle
First Claim
1. An electronic sign for installation in a passenger vehicle comprising:
- a radio receiver;
a satellite positioning system unit;
a central processing unit;
a data memory;
an electronic screen; and
a radio receiver/transmitter;
whereby said radio receiver receives a particular update signal as determined by said satellite positioning system unit, said signal being processed by said central processing unit and stored in said data memory for updating said data memory;
whereby said data memory provides updated information to said electronic screen for presentation thereon; and
whereby said data memory provides updated information to said radio transmitter, and thus said radio transmitter, for transmitting said update signal.

Abstract
A system which includes an electronic sign located in a vehicle of a passenger transportation system with the capability of showing letters, numbers and graphs. The electronic sign is equipped with a satellite based positioning system which enables specific information uploading for a particular geographical region for displaying information, news, publicity, advertisement, and services for the passenger. The electronic sign capability of determining its position allows it to locate the appropriate “uploading sites,” which automatically update information for the geographic position where the information should be addressed for any number of signs located in that geographic position. This makes it simple to advertise or inform the nearby population in a previously chosen target region.

2. A system for providing updated information to a passenger vehicle comprising:
-
an uploading site having means for transmitting an update radio signal;
at least a first and a second vehicle mounted electronic sign, each said sign having;
means for receiving an update radio signal;
means for storing update signals to form an updated database;
means to display said updated database; and
means to transmit said updated database as a radio signal;
whereby at least one of said first vehicle mounted electronic signs receives said update signal from said uploading site; and
whereby at least one of said second vehicle mounted electronic signs receives said updated database radio signal from said at least one first electronic sign.

3. A method of providing updated information to the public in at least first and second vehicles comprising;
-
providing an uploading site having means for transmitting an update radio signal;
providing at least a first and a second electronic sign corresponding to said first and second vehicles, each said sign having;
means for receiving an update radio signal;
means to display said updated database to a vehicle passenger; and
means to transmit said updated database as a radio signal;
said uploading site sending an upload radio signal to said at least first electronic sign;
said at least first electronic sign displaying data to said passengers in said first vehicle received from said uploading site by means of said upload radio signal;
said at least first electronic sign sending an upload radio signal to said at least second electronic sign; and
said at least second electronic sign storing the same data stored on said at least first electronic sign to said passengers in said second vehicle according to said at least second electronic sign position.

4. An electronic sign for information located on a vehicle of passenger transportation systems utilizing a satellite positioning system receiver in combination with a dynamic electronic sign, said sign for installation in a said vehicle of a said passenger transportation system comprising:
-
a satellite positioning system receiver;
a central processing unit;
a data memory;
an electronic screen; and
a radio receiver/transmitter;
whereby the installation of said satellite positioning system receiver combined with said dynamic electronic sign on said passenger transportation system unit creates an environment of great versatility for information, publicity, advertisement and services;
whereby said central processing unit, utilizing said radio receiver/transmitter, receives data through a radio frequency signal from a specific fixed uploading site;
whereby said fixed uploading site is accurately located by said satellite positioning system receiver. whereby said central processing unit, utilizing said radio receiver/transmitter may receive data through radio frequency signal from another identical electronic sign mounted in another vehicle;
whereby said radio receiver/transmitter of said sign and said radio receiver/transmitter of said another identical electronic sign mounted in another vehicle run spread-spectrum with the same noise code;
whereby the entire electronic sign system is synchronized with said satellite positioning system;
said fixed uploading site comprising;
a modem connected to a telephone line;
a satellite positioning system receiver;
a central processing unit;
a data memory;
a radio receiver/transmitter;
means for receiving new information through said modem;
means for processing said new information by its said central processing unit; and
means for storing said new information in its said data memory;
whereby said new information received through radio frequency by said central processing unit of said electronic sign is verified and stored in said data memory of said electronic sign;
whereby said new information updates existing data stored at said data memory of said electronic sign;
whereby said updated data stored in said data memory of said electronic sign have the information to be displayed at said electronic screen and the coordinates(longitude, latitude) of where said information should be displayed;
whereby said central processing unit of said electronic sign receives said coordinates(longitude, latitude) from said satellite positioning system receiver of said electronic sign; and
whereby, according to said coordinates (latitude, longitude) and said data stored in said data memory, said central processing unit updates information to be displayed at said electronic screen;
thus creating an environment of great versatility for information, publicity, advertisement and services. - View Dependent Claims (5, 6, 7, 8, 9, 10)
