Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
51 words
A talking crystal ball toy comprising a light-permeable sphere mounted on a base which contains a photosensitive element from which a double interruption of light activates a speech synthesis circuit which generates an an audio output of a digitally pre-recorded voice response to a question asked of the said crystal ball.
Claim 2
Dependent Claim
51 words
A talking crystal ball toy comprising a light-permeable sphere mounted on a base which contains a photosensitive element from which a double interruption of light activates a speech synthesis circuit which generates an an audio output of a digitally pre-recorded voice response to a question asked of the said crystal ball.
Claim 3
Dependent Claim
28 words
A talking crystal ball toy as described in claim 1 wherein the said voice response is randomly chosen from a total of twenty eight possible pre-recorded voice responses.
Claim 4
Dependent Claim
18 words
A talking crystal ball toy as described in claim 1 wherein the said photosensitive element is a photodiode.
Claim 5
Dependent Claim
24 words
A talking crystal ball toy as described in claim 1 wherein the said speech synthesis circuit contains a Texas Instruments TSP50C41 speech synthesis chip.
Claim 6
Dependent Claim
30 words
A talking crystal ball toy as described in claim 1 wherein the circuit has an optional external program which contains a TI 60C20 ROM with alternate digitally pre-recorded voice responses.
Claim 7
Dependent Claim
19 words
