Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 111 words
A directional, light emitting chemiluminescent safety light, comprising: a base having a planar light reflective surface; a substantially transparent, resilient outer wall connected to the base to a side outward of the reflective surface and forming with the base a fluid-tight outer compartment for a two-component chemiluminescent system; a breakable, fluid-tight inner compartment within the outer compartment containing the first chemical component; and a second chemical component within the outer compartment and external to the breakable inner compartment whereupon deformation of the outer wall breaks the inner compartment and mixes the chemical components, a portion of the light produced being reflected off the reflected surface and transmitted through the outer wall.
Claim 2
Dependent Claim 111 words
A directional, light emitting chemiluminescent safety light, comprising: a base having a planar light reflective surface; a substantially transparent, resilient outer wall connected to the base to a side outward of the reflective surface and forming with the base a fluid-tight outer compartment for a two-component chemiluminescent system; a breakable, fluid-tight inner compartment within the outer compartment containing the first chemical component; and a second chemical component within the outer compartment and external to the breakable inner compartment whereupon deformation of the outer wall breaks the inner compartment and mixes the chemical components, a portion of the light produced being reflected off the reflected surface and transmitted through the outer wall.
Claim 3
Dependent Claim 31 words
The safety light of claim 1 wherein the base is substantially transparent and wherein the reflective surface is on the outside of the base facing inwardly towards the resilient outer wall.
Claim 4
Dependent Claim 22 words
The safety light of claim 1 wherein the outer wall has a convex dome shape and prismatic lens elements to refract light.
Claim 5
Dependent Claim 22 words
The safety light of claim 3 wherein the periphery of the base is substantially contiguous with the periphery of the outer wall.
Claim 6
Dependent Claim 21 words
The safety light of claim 4 wherein the base and outer wall are radially disk shaped to resemble an automotive reflector.
Claim 7
Dependent Claim 27 words
The safety light of claim 1 including adhesive material on the base to a side opposite the reflective surface to attach the safety light to various objects.
Claim 8
Dependent Claim 11 words
The safety light of claim 6 wherein the base is flexible.
Claim 9
Dependent Claim 19 words
The safety light of claim 1 including means for controlling the color of light emitted from the outer wall.
Claim 10
Dependent Claim 20 words
The safety light of claim 8 wherein the second chemical component in the outer compartment includes the color controlling means.
Claim 11
Dependent Claim 14 words
The safety light of claim 9 wherein the color controlling means is dyed water.
Claim 12
Dependent Claim 98 words
A directional, light emitting chemiluminescent safety light comprising: a flexible, fluid-tight outer compartment for a chemiluminescent system having a thin, substantially transparent convex wall and an inwardly facing reflective surface opposite the transparent wall; an inner breakable compartment within the outer compartment containing at least one chemical component; and at least one other chemical component within the outer compartment and external to the breakable inner compartment, whereupon deformation of the outer compartment breaks the inner compartment and mixes the chemicals, a portion of the light produced being reflected off the reflective surface and transmitted through the transparent wall.
Claim 13
Dependent Claim 98 words
A directional, light emitting chemiluminescent safety light comprising: a flexible, fluid-tight outer compartment for a chemiluminescent system having a thin, substantially transparent convex wall and an inwardly facing reflective surface opposite the transparent wall; an inner breakable compartment within the outer compartment containing at least one chemical component; and at least one other chemical component within the outer compartment and external to the breakable inner compartment, whereupon deformation of the outer compartment breaks the inner compartment and mixes the chemicals, a portion of the light produced being reflected off the reflective surface and transmitted through the transparent wall.
Claim 14
Dependent Claim 14 words
The safety light of claim 11 wherein the outer compartment is substantially dome shaped.
Claim 15
Dependent Claim 15 words
The safety light of claim 11 wherein the transparent wall has means for refracting light.
Claim 16
Dependent Claim 16 words
The safety light of claim 11 including means for connecting the safety light to various objects.
Claim 17
Dependent Claim 20 words
The safety light of claim 11 including means for controlling the color of the light emitted from the transparent wall.
Claim 18
Dependent Claim 84 words
A directional, two component chemiluminescent safety light having a substantially transparent, flexible outer wall and an inwardly facing reflective surface spaced from the outer wall to direct chemically generated light through the transparent wall wherein the safety light also has an inner, frangible compartment positioned in the space between the outer wall and the reflective surface to contain one of the chemical components so that substantial deformation of the flexible outer wall breaks the inner compartment, causing the chemicals to mix and generate light.
Claim 19
Dependent Claim 84 words
A directional, two component chemiluminescent safety light having a substantially transparent, flexible outer wall and an inwardly facing reflective surface spaced from the outer wall to direct chemically generated light through the transparent wall wherein the safety light also has an inner, frangible compartment positioned in the space between the outer wall and the reflective surface to contain one of the chemical components so that substantial deformation of the flexible outer wall breaks the inner compartment, causing the chemicals to mix and generate light.
Claim 20
Dependent Claim 106 words
A directional chemiluminescent safety light, comprising: a circular, substantially transparent and resilient convex dome connected in a spaced-apart relation to a substantially transparent flexible base, forming a fluid-tight, flexible outer compartment for a two-component chemiluminescent system; a breakable, fluid-tight inner compartment within the outer compartment containing the first chemical component; a second chemical component within the outer compartment and external to the breakable inner compartment whereupon deformation of the outer compartment breaks the inner compartment and mixes the chemical components producing light; and a light-reflecting surface on the outside of the base facing inwardly towards the dome to reflect part of the light towards the dome.
Claim 21
Dependent Claim 106 words
A directional chemiluminescent safety light, comprising: a circular, substantially transparent and resilient convex dome connected in a spaced-apart relation to a substantially transparent flexible base, forming a fluid-tight, flexible outer compartment for a two-component chemiluminescent system; a breakable, fluid-tight inner compartment within the outer compartment containing the first chemical component; a second chemical component within the outer compartment and external to the breakable inner compartment whereupon deformation of the outer compartment breaks the inner compartment and mixes the chemical components producing light; and a light-reflecting surface on the outside of the base facing inwardly towards the dome to reflect part of the light towards the dome.
Claim 22
Dependent Claim 26 words
The safety light of claim 17 wherein the dome has lens elements to refract and collimate the light transmitted through the dome in a desired direction.
Claim 23
Dependent Claim 25 words
The safety light of claim 18 including an adhesive ring connected to the outside of the base for attaching the safety light to various objects.
Claim 24
Dependent Claim 27 words
The safety light of claim 19 including a removable protective backing on the adhesive ring to protect the ring until the safety light is ready for use.
