Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
A light-emitting electronic adornment, comprising, a base item of personal adornment adapted to be worn by a person. an electronically operated plurality of light-emission means on said base item, a counting means and a plurality of switching means electrically interposed between said counting means and said plurality of light emission means, an electrical circuit including source means for applying an electrical potential across said light-emission means thereby to emit light therefrom, frequency control means electrically connected in said circuit and operative to produce output pulses of controlled frequency, pulse width means electrically connected in said circuit and operative to produce output pulses of controlled width independent of said frequency control means, said light-emission means being electrically connected in said circuit so as to receive pulses from said source means as modified by said frequency control means and said pulse width means, thereby to simulate natural flickering light, and said frequency control means comprising two light sensors and a Schmitt Trigger Gate electrically connected to said source means for producing output pulses of random frequency wherein said light sensors are connected in series.
Claim 2
Dependent Claim
182 words

Claim 5
Dependent Claim
21 words
The adornment of claim 1 wherein said frequency control means comprises a multivibrator operative to produce pulses at a fixed frequency.
Claim 6
Dependent Claim
29 words
The adornment of claim 2 or 4 wherein said frequency control means further comprises a counter/divider electrically connected in said circuit to modify the output pulses of said multivibrator.
Claim 7
Dependent Claim
