Abstract
Provided herein is a system for transmitting data to an object travelling along a surface. The object preferably contains an antenna which produces a read range having a length (L) in the direction of travel and a width (W) substantially perpendicular to the direction of travel. A first plurality of RFID transponders may be positioned within a surface as a row which is substantially perpendicular to the direction of travel. A second plurality of RFID transponders may be positioned following the first row. Depending on the speed of the object travelling the surface at this location, more rows of transponders may be used. A method for placing the RFID transponders within the surface is also disclosed.

21. A system for transmitting data to an object in a direction of travel, the object having an RFID antenna which produces a read range having a length (L) in the direction of travel and a width (W) substantially perpendicular to the direction of travel, the system comprising:
-
a first plurality of RFID transponders placed within a surface and positioned in a first row which is substantially perpendicular to the direction of travel, each transponder having data to be transferred to the object; a second plurality of transponders placed within a surface and positioned in a second row which is substantially perpendicular to the direction of travel, each transponder having data to be transferred to the object; where the second row is placed at distance (D) from the first row, where D is measured in a direction substantially parallel to the direction of travel. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A system for transmitting data to an object travelling along a surface in a direction of travel, the object having an RFID antenna which produces a read range having a length (L) in the direction of travel and a width (W) substantially perpendicular to the direction of travel, the system comprising:
-
an activation zone within the surface comprising a plurality of RFID transponders placed within the surface, each transponder having control data to be transferred to the object; a stretch of surface following the activation zone where the object operates based on the control data; and a deactivation zone following the stretch of surface and comprising a plurality of transponders placed within the surface, each transponder having release data to be transferred to the object, releasing control of the object. - View Dependent Claims (34, 35, 36)

37. A method for placing RFID transponders in a surface for data transmission to an object having a direction of travel, the method comprising the steps of:
-
(1) selecting a portion of the surface for placing the transponders; (2) determining the maximum speed attainable by the object at the selected portion of the surface; (3) determining the dimensions of read range emanating from the object, producing a length (L) in the direction travel and a width (W) in a direction substantially perpendicular to the direction of travel; (4) determining the required spacing between transponders based the results of steps (2) and (3); and (5) placing a first row of transponders across the roadway, oriented in a direction substantially perpendicular to the direction of travel, where each transponder within the row is spaced based on the results of step (4). - View Dependent Claims (38, 39, 40)
