Abstract

An identification system includes a quantum dot form factor disposed on an article, and quantum dots disposed on the quantum dot form factor, the quantum dots emitting a predetermined emission. A marking system includes a secondary reservoir including a plurality of quantum dots configured to be expelled from the reservoir and a means for dispersing the quantum dots from the secondary reservoir to engage the area to be marked. A location system includes a main reservoir having a plurality of quantum dots disposed within the main reservoir, wherein the main reservoir is a water dissolvable material that dissolves over a predetermined period while exposed to water. An identification system includes a sensor for detecting a light wave query, a strobe for flashing, and a filter that includes quantum dots that the light from the strobe energizes to emit light at a predetermined frequency.

First claim

1 - 27 . (canceled)

28 . An identification system for identifying an article, comprising:
a strobe disposed on the article to flash; a dot form factor disposed on the article with the strobe underneath the dot form factor; and a plurality of dots disposed on the dot form factor, the plurality of dots configured to emit, responsive to strobe flashing, a predetermined emission for detection by an external receiver.

29 . The system according to claim 28 , wherein the external receiver is configured to generate a disable communication in to a detection of the emission.

30 . The system according to claim 29 , wherein the disable communication is configured to disable a weapon system.

31 . The system according to claim 28 , wherein the emission comprises ultraviolet (UV) light.

32 . A marking system, comprising:
a reservoir including a plurality of dots configured for expulsion from the reservoir; a means for dispersing the dots from the reservoir to engage an area to be marked; and an external receiver configured to detect a predetermined emission from at least a portion of the plurality of dots following dispersal and upon activation of the portion of the plurality of dots by a light source.

33 . The system according to claim 32 , further comprising a dispersible material in the reservoir.

34 . The system according to claim 33 , wherein the dispersible material is mixed with the plurality of dots.

35 . The system according to claim 32 , wherein the reservoir comprises main and secondary reservoirs,
the main reservoir including compressed gas and the secondary reservoir being located within the main reservoir, and the marking system further comprising a trigger coupled to the main reservoir and the secondary reservoir.

36 . The system according to claim 35 , wherein the trigger is configured to release the compressed gas and the plurality of dots into an external environment.

37 . The system according to claim 35 , further comprising a breakable membrane disposed between the main reservoir and the secondary reservoir.

38 . The system according to claim 37 , wherein the membrane isolates the compressed gas from the plurality of dots.

39 . A location system, comprising:
a reservoir comprising a plurality of dots and a water dissolvable material that dissolves by exposure to water to disperse the plurality of dots; and an external receiver configured to detect a predetermined emission from at least a portion of the plurality of dots following dispersal and upon activation of the portion of the plurality of dots by a light source.

40 . The system according to claim 39 , wherein the reservoir comprises:
a main reservoir having a plurality of dots disposed therein; and an inner reservoir having another plurality of dots disposed therein, the main and inner reservoirs respectively comprising water dissolvable materials that respectively dissolve over predetermined periods while exposed to water.

41 . The system according to claim 40 , wherein the reservoir comprises a plurality of nested reservoirs, each having a plurality of dots disposed therein, and each comprising respective water dissolvable materials that dissolve over predetermined periods while exposed to water.

42 . An identification system for allowing identification by emission of a coded light frequency, the identification system comprising:
a sensor disposed on a first portion of an article; a strobe disposed on a second portion of the article for flashing; and a filter partially covering said strobe, said filter including dots that light from the strobe energizes to emit light at a predetermined frequency which is detectable to determine an identity.

43 . The identification system according to claim 42 , further comprising a power source coupled to the strobe.

44 . The identification system according to claim 42 , wherein the dots emit at least one of a single and multiple frequency bands.

45 . The identification system according to claim 42 , wherein the dots are tunable.

46 . The identification system according to claim 42 , wherein the article is wearable.

47 . The identification system according to claim 42 , further comprising a receiver configured to detect light emitted through the filter.

48 . The identification system according to claim 47 , wherein the receiver is configured to trigger a lockout signal to disable a weapon system.
