Claim 7
Dependent Claim 119 words
In an electronic communication terminal, the combination comprising: keyboard means for selectively keying characters, said keyboard means having an output indicative of the keyed characters; variable color display means responsive to said output for providing an indication of the keyed characters; means for measuring a predetermined quantity and for developing output signals related to the measured value of said quantity; comparator means for comparing said output signals with predetermined limits, to determine the range in which the measured value of said 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 quantity lies.
Claim 8
Dependent Claim 131 words
The combination of claim 4 wherein: said comparator means compare said output signals with predetermined low and high limits, to determine whether the measured value of said quantity is lower than said low limit, or higher than said high limit, or within the bounds of said low and high limits, and develop comparison signals accordingly; and said color control means illuminate said indication in a first color when the measured value of said diverse quantity is lower than said low limit, in a second color when the measured value of said diverse quantity is higher than said high limit, and in a third color when the measured value of said diverse quantity is within the bounds of said low and high limits, said first, second, and third colors being respectively different.
Claim 9
Independent Claim 62 words
A method of simultaneously indicating a dialed telephone number and a value of temperature, on a single variable color display means, by causing an indication of the dialed telephone number to be exhibited on said display means, by measuring temperature to obtain a value of temperature, and by controlling the color of said display means in accordance with the value of temperature.
Claim 10
Independent Claim 62 words
A method of simultaneously indicating a dialed telephone number and a value of temperature, on a single variable color display means, by causing an indication of the dialed telephone number to be exhibited on said display means, by measuring temperature to obtain a value of temperature, and by controlling the color of said display means in accordance with the value of temperature.
