Digital readout diet scale
First Claim
1. A scale for use in a personal dieting program, comprising:
- weight measuring means sensitive to weight increments at least as small as 1/2 pound for a weight measured by said scale;
means for storing a previous measurement of weight for comparison with a subsequent measurement; and
a digital display capable of displaying both said subsequent weight measured by said scale and the difference between said subsequent weight and said previous weight measured, indicating either weight gain or loss, said digital display providing for display of said subsequent weight measurement and said weight difference in increments at least as small as 1/2 pound, whereby measured weight gains and losses on the order of 1/2 pound may be observed by the user of said scale to thereby assist his dieting program.

Abstract
An electronic digital readout diet scale including means for accurately detecting and displaying minute changes of weight in a dieter accurate to small fractions of pounds is described. One embodiment comprises a transducer for generating a signal representing the weight of the dieter, and means for storing a signal representing a reference weight for the dieter. These signals are applied to a time gated oscillator whose output in turn is applied to an up-down counter. The counter is responsive to the oscillator output signals to display the dieter'"'"'s weight or change in weight, and provides a digital display of current weight or weight change. A switching device, either manual or automatic with a time delay, first couples the transducer output to the counter to display the current weight of a user and then couples the storage means to the counter to decrease the displayed weight by the reference weight, whereby the relative change of weight of the user may be displayed.

11. In a scale for use by an individual in a personal dieting program and having a digital display and means for measuring and displaying both the current weight of a user and the difference between such current weight and a previous weight, the improvement comprising:
-
said weight measuring means being adapted for measuring weight increments at least as small as 1/2 pound; and said digital display being adapted to display in 1/2 pound increments both the current weight of a user and the difference between said current weight and a preselected previous weight of such user, indicating either weight gain or loss, whereby measured weight gains and losses on the order of 1/2 pound may be observed by such user to assist his dieting program. - View Dependent Claims (12, 13, 14, 15)
