Abstract
Abstract The present invention relates to a novel and unique activated work such as a child's book or a greeting card having at least two turnable pages in juxtaposed relationship and which is formed having a portion thereof that is essentially invisible in a first state but visible in a second state. Electrical signals are coupled to the second portion for selectively and reversibly changing the second portion from the invisible to the visible state when the pages are moved from their juxtaposed relationship.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
155 words
An activated work comprising: a. at least two turnable, juxtaposed pages, b. at least one of said juxtaposed pages having a picture of a first scene on a side facing another page, c. a second scene added to and interposed with said first scene, said second scene comprising areas thereof which are formed of a material having variable electromagnetic radiation absorption characteristics and being essentially invisible in a first state and visible in an electrically changed second state, d. means on said work for producing an electrical signal when said one page is turned from its juxtaposed relationship with said other page, and e. means for coupling said electrical signal to said areas of said second scene only by turning said one page from its juxtaposed relationship with said other page such that said areas of said second scene are independently, distinctly and reversibly changed from said invisible state to said electrically changed visible state.
Claim 2
Dependent Claim
155 words
An activated work comprising: a. at least two turnable, juxtaposed pages, b. at least one of said juxtaposed pages having a picture of a first scene on a side facing another page, c. a second scene added to and interposed with said first scene, said second scene comprising areas thereof which are formed of a material having variable electromagnetic radiation absorption characteristics and being essentially invisible in a first state and visible in an electrically changed second state, d. means on said work for producing an electrical signal when said one page is turned from its juxtaposed relationship with said other page, and e. means for coupling said electrical signal to said areas of said second scene only by turning said one page from its juxtaposed relationship with said other page such that said areas of said second scene are independently, distinctly and reversibly changed from said invisible state to said electrically changed visible state.
Claim 3
Dependent Claim
13 words
Apparatus as in claim 1 wherein said activated work is a child's book.
Claim 4
Dependent Claim
85 words
A book as in claim 2 further including: a. an electrochromic material placed on said one page and used to form said second scene, and b. wherein said coupling means couples said electrical signal to said electrochromic material for automatically activating said electrochromic material to cause said second scene to be visible by turning said other page from its juxtaposed relationship with respect to said at least one page and to return to its invisible state by returning said other page to its previous position.
Claim 5
Dependent Claim
62 words
A book as in claim 3 wherein: a. said means for producing said electrical signal includes a battery, and b. said means for coupling said electrical signal to said electrochromic material includes a switch that is actuated only by turning said other page with respect to said at least one page and deactuated by returning said other page to its previous position.
Claim 6
Dependent Claim
57 words
A book as in claim 4 wherein said means for producing said electrical signal includes a photovoltaic material placed in said book such that when said other page in said book is turned with respect to said at least one page said photovoltaic material is exposed to light and generates a voltage thereby producing said electrical signal.
Claim 7
Dependent Claim
13 words
The improvement in claim 1 wherein said activated work is a greating card.
Claim 8
Dependent Claim
55 words
A book as in claim 2 further including: a. a third essentially invisible scene added to said first and second scenes, and b. means coupling said second and third scenes to said signal producing means for selectively causing at least part of said second scene to become invisible and said third scene to become visible.
Claim 9
Dependent Claim
52 words
A book as in claim 7 further including: a. a circuit coupling said second and third scenes to said electrical signal producing means for causing said second scene to become invisible and said third scene to become visible, and b. means on said at least one page for selectively activating said circuit.
Claim 10
Dependent Claim
55 words
A book as in claim 8 wherein said selectively activating means comprises: a. a capacitive touch switch mounted on said at least one page, and b. means coupling said capacitive switch to said circuit for causing said second scene to become invisible and said third scene to become visible when said capacitive switch is actuated.
Claim 11
Dependent Claim
87 words
A book as in claim 2 further including: a. a liquid crystal material forming said second scene, b. a heating element in heat transfer relationship with each part of said second scene for causing said second scene to become visible when heat is applied, and c. switch means coupling said electrical signal to said heating element to cause said heating element to generate said heat and cause said second scene to become visible in response to said book being opened to said page containing said first scene.
Claim 12
Dependent Claim
31 words
A book as in claim 10 further including: a. multiple liquid crystal areas forming said second scene, and b. a like multiple number of heating elements respectively associated with said areas.
Claim 13
Dependent Claim
20 words
A book as in claim 11 further including each of said heating elements coupled together in a series circuit arrangement.
Claim 14
Dependent Claim
17 words
A book as in claim 11 further including said heating elements connected in a circuit in parallel.
Claim 15
Dependent Claim
16 words
A book as in claim 9 further including electrochromic material forming said second and third scenes.
Claim 16
Dependent Claim
16 words
A book as in claim 9 further including liquid crystal forming said second and third scenes.
