Abstract

Electronic scales to efficiently control the amount of calories consumed include at least one weight or force sensor, a data processing unit having a memory unit, a control and input keyboard and a display device. The scales include an active bearing surface functionally connected to the weight or force sensor(s) and adapted to receive a plate of food or similar container, and the data processing unit is installed with a program which calculates the equivalent calorie value for each meal, in the form of liquid and/or solid food, based on the amount of weighed food and the stored or manually input weight-related calorie content of the meal, finally, the other food of a meal is added to the equivalent calorie content and a total value of calories of the daily consumed meal is calculated. The value is stored, displayed and/or printed out and the storage unit stores pre-programmed desired values.

Claims

1. Electronic scales for efficient monitoring of the number of calories consumed, with at least one weight sensor or force sensor, a data processing unit with memory means, a control and input keyboard and a display device, characterized in that they have an active bearing surface (5) which is functionally connected to the weight or force sensor(s) and which is adapted to holding a dinner plate or similar vessel, that the data processing unit (2) is equipped with a program which for any dish, in the form of liquid and/or solid food, based on the weighed amount of food and the weight-referenced calorie content of this food which has been stored or a manually input, computes the calorie equivalence value, adds the latter to the calorie equivalence values of the other dishes of a meal and computes the total value of the calories of foods consumed daily, and stores, displays and/or prints out this value and that the memory means (2) are suited to containing preprogrammed setpoints which are computed from the data inputs and measurements of a calibration period and are used as comparison or reference values during the period of calorie monitoring.

2. Electronic scales as claimed in claim 1, wherein the bearing surface (5) and the weight or force sensors assigned to it are designed such that plates of different sizes and shapes can be accurately weighed and wherein the program contains a routine which checks during each weight measurement phase that each weight or force sensor is loaded and is delivering a correct measurement signal which contributes to an effective measurement result.

3. Electronic scales as claimed in claim 1, wherein they contains at least one second active bearing surface (6) which separately from the first bearing surface (5) is equipped with its own weight or force sensor(s) and is functionally connected thereto and is suited for holding drinking vessels or containers, such as glasses or cups, at least one second measurement signal being delivered therefrom.

4. Electronic scales as claimed in claim 3, wherein their overall structure is essentially flat and thin, with a bearing surface (5) for the plate and a bearing surface (6) for a drinking vessel, the programming and control keyboard (3) and the display device (4) which consists for example of liquid crystal diodes, being arranged pushed to the side, and thus even when a plate and/or a drinking vessel is present, being visible or reachable.

5. Electronic scales as claimed in claim 4, wherein the scales can consist for example of two flat (jackets 1′

) which are hinged to one another via a hinge part (7), and the scales can thus be folded together when not in use and/or for transport.

6. Electronic scales as claimed in claim 1, wherein they contain blocking means which make it possible to rigidly lock the bearing surface (5) in a given position for the plate, and optionally the bearing surface (6) for the drinking vessel, outside of a measurement and computation phase and/or blocks and prevents any data transfer as the measurement signal to the data processing unit (2), thus the movements necessary for eating and drinking can be carried out safely and without disruption.

7. Electronic scales as claimed in claim 1, wherein the memory means (2′

) contain a programmable calorie equivalence table which can be interrogated and supplemented, and which can be interrogated and supplemented by data input via the keyboard 3, and interrogation can take place by input of only some of the letters of the name of the pertinent dish/food and the value which has been interrogated at the time is automatically used by the data processing unit (2) as a multiplication factor for computing the calorie value of a weighed dish/food.

8. Electronic scales as claimed in claim 7, wherein the calorie equivalence table which can be interrogated, for individuals who are suffering from a disease and thus are to consume specifically on a daily basis at least or at most values of an element or molecule, contains the specific content of the critical proportions of the given food list and its daily total is likewise computed.

9. Electronic scales as claimed in claim 1, wherein the program, upon the corresponding control by the keyboard (3), measures and stores the empty weight of the plate and/or of the drinking vessel and afterwards computes and stores the calorie value of each dish/food of a meal in place, the total calorie value of each meal and the cumulative calorie value of the different meals of a day, optionally also the plus/minus difference from a daily calorie setpoint which has been computed beforehand or input beforehand being computed and displayed.

10. Electronic scales as claimed in claim 1, wherein the stored values, optionally supplemented by a date and/or time indication and/or by data which have been input manually via the keyboard (3), can be transmitted from the corresponding integrated or separate connected means to a data medium, such as for example a sheet of paper, an electronic data card, a solid state memory or the like.

11. Electronic scales as claimed in claim 1, wherein they likewise have means for visual or audible reproduction of reports, especially of result reports, comments, warnings, deviations from the stored diet program and the like.

12. Process for monitoring the food consumption of an individual within the framework of a diet and using electronic scales as claimed in claim 1, wherein the process in terms of time consists of three successive phases, specifically a first calibration period of limited duration, a subsequent effective diet period and finally a long-term stabilization period, during all three periods the daily calorie equivalence values of the foods consumed being computed by means of the electronic scales (1), by weighing the individual foods of each meal, computing the corresponding calories and adding up the latter for each day of these three periods, in the third period or stabilization period the efficiency or the correctness of the number of calories consumed daily being monitored by regularly determining the body weight by weighing, and if necessary being empirically corrected to maintain the desired body weight.

13. Process a claimed in claim 12, wherein the values with respect to daily calorie intake of the individual during the first phase are used as the basis for computing reference values for the second and third phase, in the second and third phase a deviation of the effective daily calorie intake value from the corresponding reference value computed beforehand being displayed and/or reported.

14. Process a claimed in claim 1, wherein the reference value of the second phase constitutes 0.75 to 0.90 of the daily average of the first phase and the reference value of the third phase constitutes 0.95 to 1.15 of the daily average of the second phase, the reference value of the third phase optionally being empirically adjustable in conjunction with the prevailing weight change of the individual.

15. Process as claimed in claim 12, wherein the second phase ends with reaching the desired weight of the individual.

16. Process as claimed in claim 12, wherein for specific diet programs, in addition to the total calorie value of the food consumed, by expanding the stored calorie values of the individual foods, by additional storage of the content of proteins, carbohydrates, fat or other foods which are to be limited for medical reasons can be measured and thus can be kept within the desired limits.

17. Electronic scales as claimed in claim 2, wherein they contains at least one second active bearing surface (6) which separately from the first bearing surface (5) is equipped with its own weight or force sensor(s) and is functionally connected thereto and is suited for holding drinking vessels or containers, such as glasses or cups, at least one second measurement signal being delivered therefrom.

18. Process a claimed in claim 13, wherein the reference value of the second phase constitutes 0.75 to 0.90 of the daily average of the first phase and the reference value of the third phase constitutes 0.95 to 1.15 of the daily average of the second phase, the reference value of the third phase optionally being empirically adjustable in conjunction with the prevailing weight change of the individual.

19. Process as claimed in claim 13, wherein the second phase ends with reaching the desired weight of the individual.

20. Process as claimed in claim 13, wherein for specific diet programs, in addition to the total calorie value of the food consumed, by expanding the stored calorie values of the individual foods, by additional storage of the content of proteins, carbohydrates, fat or other foods which are to be limited for medical reasons can be measured and thus can be kept within the desired limits.
