A system, for calculating an object location within a portal, includes a portal map formed by a plurality of infra-red beams. The system further includes a broken beam detector for detecting and recording, in response to an object moving through the portal map, data indicative of one or more broken beams of the plurality of infra-red beams. The data includes first data indicative of an initial position of the object within the portal, second data indicative of a subsequent position of the object within the portal, and third data including one or more time records. The system also includes at least one broken beam analyzer for obtaining the data from the broken beam detector, the broken beam analyzer calculating the object location based on at least one of the first data, the second data, and the third data. |

1. A system for calculating an object location within a portal, the system comprising:
at least one portal map formed by a plurality of infra-red beams, wherein the plurality of infra-red beams includes one or more perpendicular infra-red beams and one or more diagonal infra-red beams; said at least one portal map created using one or more transmitters and one or more receivers, further wherein each transmitter transmits at least one perpendicular beam and at least one diagonal beam, and wherein each receiver receives at least one perpendicular beam and at least one diagonal beam; a broken beam detector for detecting and recording, in response to an object moving through the at least one portal map, data indicative of one or more broken beams of the plurality of infra-red beams, the data including first data, second data, and third data, the first data being indicative of an initial position of the object within the portal, the second data being indicative of a subsequent position of the object within the portal, and the third data including one or more time records; and at least one broken beam analyzer for obtaining the data from the broken beam detector, the broken beam analyzer calculating the object location based on at least one of the first data, the second data, and the third data. |
