Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 52 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; means for measuring a diverse quantity and for developing output signals related thereto; and color control means responsive to said output signals for controlling the color of said indication in accordance with said diverse quantity.
Claim 2
Dependent Claim 52 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; means for measuring a diverse quantity and for developing output signals related thereto; and color control means responsive to said output signals for controlling the color of said indication in accordance with said diverse quantity.
Claim 3
Dependent Claim 21 words
A timepiece as defined in claim 1 wherein said color control means controls the color of said indication in three steps.
Claim 4
Dependent Claim 146 words
A timepiece as defined in claim 1 more characterized by: comparator means for effecting a comparison of said output signals with a low and high predetermined limits to determine whether measured value of said diverse quantity is lower than said low predetermined limit, or higher than said high predetermined limit, or within the bounds of said low and high predetermined limits, and for developing comparison signals accordingly; and said color control means illuminating said indication in a first color when the measured value of said diverse quantity is lower than said low predetermined limit, in a second color when the measured value of said diverse quantity is higher than said high predetermined limit, and in a third color when the measured value of said diverse quantity is within the bounds of said low and high predetermined limits, said first, second, and third colors being respectively different.
Claim 5
Dependent Claim 55 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; temperature transducer means for measuring temperature and for developing output electrical signals related thereto; and color control means responsive to said output electrical signals for controlling the color of said indication in accordance with the values of temperature.
Claim 6
Dependent Claim 55 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; temperature transducer means for measuring temperature and for developing output electrical signals related thereto; and color control means responsive to said output electrical signals for controlling the color of said indication in accordance with the values of temperature.
Claim 7
Dependent Claim 147 words
A timepiece as defined in claim 4 more characterized by: comparator means for effecting a comparison of measured value of temperature with a low and high predetermined limits to determine whether the measured value of temperature is lower than said low predetermined limit, or higher than said high predetermined limit, or within the bounds of said low and high predetermined limits, and for developing comparison signals accordingly; and said color control means being responsive to said comparison signals for illuminating said indication in a first color when the measured value of temperature is lower than said low predetermined limit, in a second color when the measured value of temperature is higher than said high predetermined limit, and in a third color when the measured value of temperature is within the bounds of said low and high predetermined limits, said first, second, and third colors being respectively different.
Claim 8
Dependent Claim 94 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; means for measuring a diverse quantity and for developing output signals related thereto; comparator means for effecting a comparison of said output signals with predetermined limits, to determine the range in which the measured value of said diverse quantity lies, and for developing comparison signals accordingly; and color control means responsive to said comparison signals for controlling the color of said indication in accordance with the range in which the measured value of said divrse quantity lies.
Claim 9
Dependent Claim 94 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; means for measuring a diverse quantity and for developing output signals related thereto; comparator means for effecting a comparison of said output signals with predetermined limits, to determine the range in which the measured value of said diverse quantity lies, and for developing comparison signals accordingly; and color control means responsive to said comparison signals for controlling the color of said indication in accordance with the range in which the measured value of said divrse quantity lies.
Claim 10
Dependent Claim 92 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; temperature transducer means for measuring temperature and for developing output electrical signals related thereto; comparator means for effecting a comparison of said output electrical signals with predetermined limits, to determine the range in which the measured value of temperature lies, and for developing comparison signals accordingly; and color control means responsive to said comparison signals for controlling the color of said indication in accordance with the range in which the measured value of temperature lies.
Claim 11
Dependent Claim 92 words
A timepiece comprising: timekeeping means; variable color analog display means for providing an analog indication of time; temperature transducer means for measuring temperature and for developing output electrical signals related thereto; comparator means for effecting a comparison of said output electrical signals with predetermined limits, to determine the range in which the measured value of temperature lies, and for developing comparison signals accordingly; and color control means responsive to said comparison signals for controlling the color of said indication in accordance with the range in which the measured value of temperature lies.
