Laser image projection system with safety means
First Claim
1. An image projection system for use at a venue having a field onto which an image is to be projected thereby, said system comprising laser means and control means for generating and projecting said image onto said field, said projection system additionally comprising a safety override means coupled to said control means for determining if a living being is approaching said field and for providing an electrical signal so that said image may be terminated in response thereto, said safety override means comprising means for establishing an enclosure, with an area larger than said field, around the periphery of said field and for providing said electrical signal should a living being traverse said enclosure.

Abstract
An image projection system and method of use at a venue, e.g., a sports or entertainment arena, having an area or field into which an image is to be projected by the system. The system includes laser devices and associated components, e.g., a computer-based controller, for generating and projecting the image into the field. The projection system additionally comprises an override subsystem, e.g., infrared transmitters and associated detectors, forming an enclosure surrounding the field for determining if a living being has entered the field and for providing an electrical signal indicative thereof. This signal may be used automatically or manually for effecting the termination of the display.
