Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A photodosimeter comprising: a housing having an opening, means mounted beneath said opening for generating an output signal having a magnitude proportional to the intensity of ultraviolet radiation entering said housing opening, means for manually inputting and storing a value corresponding to the solar protection factor of a sunscreen material, means for accumulating said output signals and for storing the accumulated result, means for dividing said accumulated result by said value corresponding to said solar protection factor, means for actuating an alarm when the result of said division exceeds a predetermined amount.
Claim 2
Dependent Claim
92 words
A photodosimeter comprising: a housing having an opening, means mounted beneath said opening for generating an output signal having a magnitude proportional to the intensity of ultraviolet radiation entering said housing opening, means for manually inputting and storing a value corresponding to the solar protection factor of a sunscreen material, means for accumulating said output signals and for storing the accumulated result, means for dividing said accumulated result by said value corresponding to said solar protection factor, means for actuating an alarm when the result of said division exceeds a predetermined amount.
Claim 3
Dependent Claim
18 words
The invention as defined in claim 1 wherein said inputting means comprises a keyboard mounted to said housing.
Claim 4
Dependent Claim
42 words
The invention as defined in claim 1 wherein said generating means comprises a photocell mounted to said housing beneath said housing opening, an analog to digital converter, said photocell having an output which forms an input to the analog to digital converter.
Claim 5
Dependent Claim
18 words
The invention as defined in claim 3 wherein said accumulating means and said dividing means comprises a microprocessor.
Claim 6
Dependent Claim
85 words
The invention as defined in claim 2 and comprising means mounted to said housing for displaying a value and wherein said keyboard comprises a first key for displaying the solar protection factor on said display means, a second key for increasing the value of the solar protection factor, and a third key for decreasing the value of the solar protection factor, said second and third keys being operable to vary the value of the solar protection factor only upon the depression of said first key.
Claim 7
Dependent Claim
37 words
The invention as defined in claim 1 and comprising means for inputting and storing a further value corresponding to the relative radiation sensitivity of a person and means for varying said predetermined amount by said further value.
Claim 8
Dependent Claim
29 words
The invention as defined in claim 3 and comprising an optical filter which passes radiation only in the ultraviolet range, said filter positioned between said photocell and said opening.
