Network Security and Variable Pulse Wave Form with Continuous Communication

Abstract

A pulsed light communication device has a plurality of indicator light emitting diodes emitting diodes emitting at least one of a plurality of wavelengths of colored light to correspond to a designated color assigned to a security level for a network. A continuous uninterrupted modulated pulsed light emitting diode light signal may be generated having a sensitivity threshold detection level exceeding minimal parameters of a photodetector.

What is claimed is: 
     
         1 . A security system comprising:
 a pulsed light communication device, said pulsed light communication device comprising a controller, a plurality of transmission light emitting diodes, and at least one photo detector, said plurality of transmission light emitting diodes emitting at least one of a plurality of wavelengths of colored light, said controller being in communication with said plurality of transmission light emitting diodes, said at least one photo detector, and at least two networks, each of said at least two networks having a different network security level, each of said network security levels being identified by at least one of said plurality of wavelengths of colored light, said controller being constructed and arranged to communicate with each of said networks and to illuminate at least one of said plurality of transmission light emitting diodes to emit said at least one wavelength of colored light identified for each of said network security levels.   
     
     
         2 . The security system according to  claim 1 , further comprising a second pulsed light communication device comprising at least one second transmission light emitting diode, and at least one second photo detector, said at least one second transmission light emitting diode emitting at least one of a plurality of wavelengths of colored light; and
 a second controller in communication with said at least one second transmission light emitting diode, and said at least one second photo detector;   wherein said second controller is in communication with at least one of said at least two networks, said second controller being constructed and arranged to illuminate said at least one second transmission light emitting diode to emit said at least one wavelength of colored light identified for said network security level for said at least one network.   
     
     
         3 . The security system according to  claim 1 , further comprising a managed switch, said managed switch being in communication with said controller, said managed switch providing access to said at least two networks. 
     
     
         4 . The security system according to  claim 1 , said controller being constructed and arranged to operate in a first state to illuminate at least one of said plurality of transmission light emitting diodes to emit a first wavelength of colored light. 
     
     
         5 . The security system according to  claim 4 , said controller being constructed and arranged to operate in a second state to illuminate at least one of said plurality of transmission light emitting diodes to emit a second wavelength of colored light. 
     
     
         6 . The security system according to  claim 5 , said second state representing unauthorized access to said second network.
