Laser locating and tracking system for externally activated tags
First Claim
1. A system for identification and tracking of a tag distributed in a room, comprising:
- a laser base station to scan laser beams through a portion of a room;
a tag reactive to incident laser beams scanned from the laser base station to provide a data signal back to the laser base station; and
a tag tracking system to receive input derived from the data signal from the laser base station, the tag tracking system storing state records of position and informational content of the tag generated from the input, wherein the tag tracking system determines angular position of the tag with respect to the laser base station based on the position and information content of the tag stored in the state records.

Abstract
A system for identification and tracking of a tag distributed in a room is presented. A laser base station is configured to scan laser beams through a portion of a room. A tag is configured to be reactive to incident laser beams scanned from the laser base station to provide a data signal back to the laser base station. A tag tracking system is configured to receive input derived from the data signal from the laser base station. The tag tracking system stores state records of position and informational content of the tag generated from the input. The tag tracking system determines angular position of the tag with respect to the laser base station based on the position and information content of the tag stored in the state records.

7. A system for identification and tracking of a tag distributed in a room, comprising:
-
at least two laser base stations to scan laser beams through a portion of a room;
a tag reactive to incident laser beams scanned from the at least two laser base stations to provide data signals back to the at least two laser base stations; and
a tag tracking system to receive input derived from the data signals from the at least two laser base stations, the tag tracking system storing state records of position and informational content of the tag generated from the input, wherein the tag tracking system determines an absolute position of the tag in the room based on the position and information content of the tag stored in the state records. - View Dependent Claims (8, 9, 10, 11, 12)
