Abstract
Abstract A visual indicating system comprised of a translucent panel including an opaque reflected image formed on its front surface and an opaque coating on its back surface which includes uncoated areas which form a transmitted image. The transmitted light image includes areas colored identically to the reflective image which are positioned immediately behind and encompassing the reflective image of similar color. Selective illumination means are disposed for illuminating the translucent panel thereby causing one of the images to be dominate over the other.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
83 words
A visual indicating system, comprising: a translucent panel including front and back surfaces, an opaque reflective image formed on said front surface, an opaque coating on said back surface including uncoated areas forming a transmitted light image, said transmitted light image including areas colored identically to said reflective image and positioned immediately behind and encompassing said reflective image of similar color, and selective illumination means disposed for illuminating said translucent panel thereby causing one of said images to be dominant over the other.
Claim 2
Dependent Claim
83 words
A visual indicating system, comprising: a translucent panel including front and back surfaces, an opaque reflective image formed on said front surface, an opaque coating on said back surface including uncoated areas forming a transmitted light image, said transmitted light image including areas colored identically to said reflective image and positioned immediately behind and encompassing said reflective image of similar color, and selective illumination means disposed for illuminating said translucent panel thereby causing one of said images to be dominant over the other.
Claim 3
Dependent Claim
40 words
The system of claim 1 wherein said reflective image is illuminated by ambient light and said selective illumination means includes a dominant light source disposed behind said translucent panel for selectively illuminating said transparent image and masking said reflective image.
Claim 4
Dependent Claim
42 words
The system of claim 1 wherein said translucent image is illuminated by ambient light and said selective illumination means includes a dominant light source disposed in front of said translucent panel for selectively illuminating said reflective image and masking said translucent image.
Claim 5
Dependent Claim
46 words
The system of claim 1 wherein said selective illumination means includes a first dominant light source disposed in front of said translucent panel for selectively illuminating said reflective image, and a second dominant light source disposed behind said translucent panel for selectively illuminating said transparent image.
Claim 6
Dependent Claim
27 words
The system of claim 2 wherein said dominant light source includes configured light conducting rods and separate illumination means to selectively illuminate individual ones of said rods.
Claim 7
Dependent Claim
28 words
The system of claim 4 wherein said second dominant light source includes configured light conducting rods, and separate illumination means to selectively illuminate individual ones of said rods.
Claim 8
Dependent Claim
65 words
The system of claim 4 wherein said second dominant light source includes at least one light conductive medium formed in a desired pattern and actuated by at least one light source, and at least one other light conductive medium formed in a different desired pattern and actuated by a second light source, said light conductive medium being scarred in areas selected to radially pass light.
Claim 9
Dependent Claim
23 words
The system of claim 7 wherein said light conductive mediums are rods arranged in separate planes in the proximity of said translucent panel.
Claim 10
Dependent Claim
29 words
The system of claim 4 wherein said second dominant light source includes a light conductive design configuration in the proximity of said translucent panel and arranged for illumination thereof.
Claim 11
Dependent Claim
42 words
The system of claim 4 wherein said second dominant light source includes a plurality of light conductive mediums, said mediums forming a bundle illuminated at one end and the other ends of said mediums being grouped into features of said transparent image.
Claim 12
Dependent Claim
28 words
The system of claim 4 further including an opaque shell for containing said second dominant light source, said translucent panel being affixed across an aperture in said shell.
Claim 13
Dependent Claim
15 words
The system of claim 1 wherein said transparent image is replaced by an opaque image.
Claim 14
Dependent Claim
17 words
The system of claim 1 wherein said transparent image or said reflective image contains a fluorescent substance.
Claim 15
Dependent Claim
20 words
The system of claim 1 further including means for selectively actuating said selective illumination means in response to ambient changes.
Claim 16
Dependent Claim
65 words
The system of claim 1 wherein said dominant light source includes at least one light conductive medium formed in a desired patTern and actuated by said at least one light source; and at least one other light conductive medium formed in a different desired pattern and actuated by a second light source; said light conductive mediums being scarred in areas selected to radially pass light.
Claim 17
Dependent Claim
23 words
The system of claim 15 wherein said light conductive mediums are rods arranged in separate planes in the proximity of said translucent panel.
Claim 18
Dependent Claim
28 words
The system of claim 2 wherein said dominant light source includes a light conductive design configuration in the proximity of said translucent panel and arranged for illumination thereof.
Claim 19
Dependent Claim
27 words
The system of claim 2 further including an opaque shell for containing said dominant light source; said translucent panel being affixed across an aperture in said shell.
Claim 20
Dependent Claim
42 words
The system of claim 14 wherein said means for selectively actuating includes a transducer for actuating said selective illumination means as said ambient condition varies about a preselected level; and a bistable control circuit which changes condition in response to said variations.
Claim 21
Dependent Claim
25 words
The system of claim 19 wherein said transducer is a sound responsive element and said bistable control circuit includes a pair of separately actuated thyristors.
Claim 22
Dependent Claim
20 words
The system of claim 20 wherein said control circuit further includes an integrator for changing the condition of said thyristors.
Claim 23
Dependent Claim
41 words
The system of claim 2 wherein said dominant light source includes a plurality of light conductive mediums; said mediums forming a bundle illuminated at one end and the other ends of said mediums being grouped into features of said transparent image.
Claim 24
Dependent Claim
31 words
The system of claim 19 further including means for delaying actuation of said selective illumination means for a predetermined period of time after said ambient condition returns to said preselected level.
Claim 25
Dependent Claim
24 words
The system of claim 19 wherein said selective illumination means remains in a switched state until said ambient condition falls below said preselected level.
