Abstract
Abstract According to the invention, a multiranging scale which operates in two weighing modes, a high range mode and a low range mode, and which displays not only weight but rate and/or charge information associated with mailing or shipping an article, is inhibited from displaying or outputting a signal indicative of the rate and/or charge when in the high range mode of operation the weight of the article is below a threshold, thereby causing the user to select the low range mode of operation. In addition to inhibiting the rate/charge display an audible or visual signal may be provided to more actively cue the user to switch to the low range weighing mode.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
An electronic scale for weighing an article, comprising: first means for providing an output indicative of the weight of an article; a data bearing element for providing rate information relevant to shipping or mailing the article; a programmed microprocessor for providing a signal indicative of the charge for mailing or shipping the article in response to the output of the first means and reflecting the information from the data bearing element; manually operable switch means coupled to the microprocessor for causing the microprocessor to operate in one of two weighing modes, being a high range mode and a low range mode; wherein the microprocessor is inhibited from providing the signal indicative of the charge for mailing or shipping the article when operating in the high range mode and the weight of the article is below a threshold, the threshold being from 1-5% of the full range of the high range mode.
Claim 2
Dependent Claim
151 words
An electronic scale for weighing an article, comprising: first means for providing an output indicative of the weight of an article; a data bearing element for providing rate information relevant to shipping or mailing the article; a programmed microprocessor for providing a signal indicative of the charge for mailing or shipping the article in response to the output of the first means and reflecting the information from the data bearing element; manually operable switch means coupled to the microprocessor for causing the microprocessor to operate in one of two weighing modes, being a high range mode and a low range mode; wherein the microprocessor is inhibited from providing the signal indicative of the charge for mailing or shipping the article when operating in the high range mode and the weight of the article is below a threshold, the threshold being from 1-5% of the full range of the high range mode.
Claim 3
Dependent Claim
79 words
An electronic scale according to claim 1, further comprising: a display responsive to the output of the first means for displaying the weight of the article and responsive to the signal from the microprocessor for displaying the charge for mailing or shipping the article; wherein the display is inhibited from displaying the charge for mailing or shipping the article when the scale is operating in the high range mode and the weight of the article is below said threshold.
Claim 4
Dependent Claim
30 words
An electronic scale according to claim 2 wherein the display is operable to display the weight of the article independently of displaying the charge for mailing or shipping the article.
Claim 5
Dependent Claim
36 words
An electronic scale according to claim 1, further comprising means for audibly or visually alerting the user when the microprocessor is inhibited from providing the signal indicative of the charge for mailing or shipping the article.
Claim 6
Dependent Claim
58 words
An electronic scale according to claim 1, wherein: the microprocessor is operable to provide a signal indicative of rate information for the article; and wherein the microprocessor is inhibited from providing the signal indicative of the rate information for the article when operating in the high range mode and the weight of the article is below said threshold.
