Abstract

A digital scale includes a display and buttonless top platform. Contact with the scale platform alone allows a user to power the scale, identify a user of the scale, determine a mode of operation of the scale, and to establish a reminder. The scale has a first mode of operation displaying a reading of the user'"'"'s weight. The scale has a second mode of operation providing a display of the user'"'"'s current weight, a delta or differential weight with the most recent recorded weight measurement and if the data is available, additional deltas for weight measurements taken up to one year earlier. The scale has a third mode of operation in which it provides a reminder for tasks to be undertaken by a user within a specified time.

Claims

1. A digital scale comprising:

a display;

a buttonless top platform;

a controller operatively associated with said display and said top platform wherein physical contact with said platform activates said scale, determines a mode of operation from among a plurality of independent modes of operation and identifies a user of said scale;

a memory for storage of measured weight values; and

wherein said controller comprises a clock for generating a relative date-stamp for each of said stored measured weight values based on the period of time that has passed since the initial application of electrical energy to said scale.

2. The scale of claim 1, wherein a first mode of operation measures and displays a user'"'"'s weight.

3. The scale of claim 1, wherein a second mode of operation measures and displays at least a user'"'"'s current weight and a delta weight value between the user'"'"'s current weight and a most recently stored measured weight value.

4. The scale of claim 3, wherein said second mode of operation additionally displays any delta weight values between the user'"'"'s current weight and the stored measured weight values most closely aligned with four, eight and twelve weeks earlier, selection of the most appropriate stored measured weight values being based on the relativistic date-stamp associated with each stored measured weight value.

5. The scale of claim 4, wherein said display includes a combination numerical and textual indication of the relativistic time period between the current measured weight value and said delta weight values.

6. The scale of claim 3, wherein said display provides a visual positive/negative indicator of the delta weight value relative to said current measured weight value.

7. The scale of claim 1, wherein a third mode of operation functions to provide said user a reminder of an important event or task.

8. The scale of claim 7, wherein either one of said first or said second modes of operation may simultaneously function during the performance of the third mode of operation.

9. The scale of claim 1, wherein said display is a multi-segment LED or LCD display.

10. The scale of claim 1, wherein said scale has a plurality of display animations indicative of the operation said scale is performing.

11. The scale of claim 10, wherein said individual display animations include indications for an error, the calibration of the scale, the measurement of a weight value, and the reset of data for a given user.

12. A method of using a digital scale comprising a display, a buttonless top platform, a controller operatively associated with said display and said top platform wherein physical contact with said platform allows a user of said scale to activate said scale, determine a mode of operation of said scale and identify a user of said scale, a memory for storage of measured weight values, and wherein said controller comprises a clock for generating a relativistic date-stamp for each of said stored measured weight values based on the period of time that has passed since the initial application of electrical energy to said scale, said method comprising:

physically contacting said platform to power on said scale and to determine said operating mode of said scale;

using said platform to identify said user of said scale;

displaying a current measured weight value in a first mode of operation or displaying a current measured weight value and at least a delta weight value between the current measured weight value and the most recently stored measured weight value in a second mode of operation; and

automatically powering off said scale after said reading is displayed.

13. The method of claim 12, wherein said a first mode of operation functions to measure and display a user'"'"'s weight.

14. The method of claim 12, wherein said second mode of operation additionally displays any delta weight values between the user'"'"'s current weight and the stored measured weight values most closely aligned with four, eight and twelve weeks earlier, selection of the most appropriate stored measured weight values being based on the relativistic date-stamp associated with each stored measured weight value.

15. The method of claim 14, further comprising the step of displaying a combination numerical and textual indication of the relativistic time period between the current measured weight value and said delta weight values.

16. The method of claim 12, wherein said second mode of operation further comprises the step of displaying a visual positive/negative indicator of the delta weight value relative to said current measured weight value.

17. A digital scale comprising:

a display;

a buttonless top platform;

a controller operatively associated with said display and said top platform wherein physical contact with said platform allows a user of said scale to activate said scale, determine a mode of operation from among a plurality of independent modes of operation and identify a user of said scale;

a memory for storage of measured weight values, wherein said memory may be reset on a user-by-user basis through physical contact with said top platform; and

wherein said controller comprises a clock for generating a relative date-stamp for each of said stored measured weight values based on the period of time that has passed since the initial application of electrical energy to said scale.

18. The scale of claim 17, wherein said scale has a plurality of display animations indicative of the operation said scale is performing.
