ABSTRACT:
The present invention relates to an automated safety system having at least one projector to direct electromagnetic energy into a region of space associated with a security, warning, or safety zone. A detector or detectors senses an interruption of the electromagnetic energy in the region of space by an object or person that may enter the space. The system includes a processor and a storage component, wherein the processor determines the interruption by comparing a current image from the detector with a previously stored image in the storage component. Upon detection, the processor triggers an event based upon the comparison, whereby the event includes such aspects as activating an output, de-energizing a machine, sounding a warning, sounding an alarm, storing data associated with the event, and sending a notification to a local or a remote system, for example.
