US 4,907,179 A · Electronic balance with quasi analog and digital display

Abstract

An electronic balance with a digital display for the exact display of the weighing result, with an quasi analog display for the estimated display of the balance (gross) load, whereby the a quasi analog display consists of at least one horizontal band of activatable points (7), and with a taring operation, that suitable activatable segments (8, 10) be located within, directly above or directly below the first horizontal band of activatable points (7) with which such suitable segments a "T" symbol (9) can be activated at a plurality of positions along the first horizontal band and that the "T: symbol be activated during taring at the horizontal position which corresponds to said tare weight on the horizontal band (7) of the quasi analog display while a horizontal bar formed by suitable activation of activatable points indicates gross weight. This makes it possible to display in a simple manner the relative position at which taring was performed. Still other segments (8, 10') can also be used in an advantageous manner as a scale for the quasi analog display.

Dependent claims

An electronic balance system comprising:

a balance weighing device producing a signal indicative of weight placed thereupon,
a digital display,
a quasi-analog display,
said display comprising
a horizontal band of activatable points,
said points having a full, faded, or null display intensity,
a digital signal processing unit having a tare memory,
a tare actuation button,
said band including a displayable horizontal bar and a displayable tare symbol,
said bar and said symbol displayed by separate activation of suitable of said activatable points
and wherein
said processing unit causes
(a) said digital display to digitally display (gross weight - tare weight),
said tare weight being a gross weight measured and stored in said tare memory upon actuation of said tare actuation button, and
(b) said quasi-analog display to:
(i) display said tare symbol at approximately a horizontal position of ratio of ##EQU1## from the left of said horizontal band from a time substantially starting with actuation of said tare actuation button, and
(ii) display said horizontal bar to approximately a horizontal position of ##EQU2## from the left of said horizontal band.
