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.

Claims

1. A security system comprising:

a pulsed light communication device comprising at least one transmission light emitting diode, at least one photo detector, and a plurality of indicator light emitting diodes, said plurality of indicator light emitting diodes emitting at least one of a plurality of wavelengths of colored light;

a controller in communication with said at least one transmission light emitting diode, said at least one photo detector, and said plurality of indicator light emitting diodes; and

a managed switch in communication with said controller, said managed switch providing access to at least two networks, each of said at least two networks having different network security levels, each of said network security levels being identified by a different wavelength of colored light;

wherein said controller is constructed and arranged to communicate with said at least two networks and to illuminate said indicator 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, said controller being constructed and arranged to operate in a first state to illuminate said indicator light emitting diodes to emit a first wavelength of colored light.

3. The security system according to claim 2, said controller being constructed and arranged to operate in a second state to illuminate said indicator light emitting diodes to emit a second wavelength of colored light.

4. The security system according to claim 3, said second state representing unauthorized access to said second network.

5. A security system comprising:

an electronic device, said electronic device being in communication with a pulsed light communication device, said electronic device comprising a controller, at least one transmission light emitting diode, at least one photo detector, and a plurality of indicator light emitting diodes, said plurality of indicator light emitting diodes emitting at least one of a plurality of wavelengths of colored light, said controller being in communication with said at least one transmission light emitting diode, said at least one photo detector, and said plurality of indicator light emitting diodes, 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 said indicator light emitting diodes to emit said at least one wavelength of colored light identified for each of said network security levels.

6. The security system according to claim 5, comprising a second pulsed light communication device comprising at least one second transmission light emitting diode, at least one second photo detector, and a plurality of second indicator light emitting diodes, said plurality of second indicator light emitting diodes 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 diodes, said at least one second photo detector, and said plurality of second indicator light emitting diodes;

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 communicate with said at least one network and to illuminate said second indicator light emitting diodes to emit said at least one wavelength of colored light identified for said network security level for said at least one network.
