Abstract

A body weight scale system with historical display. The system includes a transducer for generating a succession of digital weight signals representative of a user'"'"'s body weight at a succession of points in time. The system further includes a data entry device which provides time signals representative of the points in time associated with the various weight signals. A data processing network stores the time and weight signals, selectively extracts those signals and generates display signals representative of the body weight of the person as a function of time. A display is responsive to the display signals to display information representative of this time function.

Claims

1. A digital body weight scale system with historical display, comprising:

A. transducer including a force sensor and associated means for generating digital weight signals representative of the body weight of a person in sensed relation with said sensor,

B. data entry means for generating a digital time signal representative of a point in time associated with the generation of one of said weight signals,

C. storage means for storing said time signals and said weight signals,

D. control means including addressing means for controlling the storage of said time signals and said weight signals in said storage means, and further including signal processing means for selectively extracting said stored time and weight signals and generating display signals therefrom, said display signals being representative of the body weight of said person as a function of time, and

E. display means responsive to said display signals for displaying information representative of said body weight as a function of time,

wherein said display includes;

a rectangular array of selectively operative light generating cells including a succession of m columns of cells, each column having n cells therein where m and n are integers, wherein the cells of each column in said succession are associated with a corresponding point of a succession of points in time, and each cell of a column is representative of a predetermined weight associated with the point in time for that column, and

means responsive to said display signals to selectively illuminate at least one cell in each column having an associated point in time corresponding to the point in time associated with said generation of one of said weight signals, said one illuminated cell being representative of the body weight represented by that weight signal.

2. A system according to claim 1 wherein said selective illuminating means includes means to illuminate the cells in said columns below said one illuminated cell in said columns.

3. A system according to claim 1 wherein said selective illuminating means includes means to illuminate the cells in said columns above said one illuminated cell in said columns.

4. A digital body weight scale system with historical display, comprising:

A. transducer including a force sensor and associated means for generating digital weight signals representative of the body weight of a person in sensed relation with said sensor,

B. data entry means for generating a digital time signal representative of a point in time associated with the generation of one of said weight signals,

C. storage means for storing said time signals and said weight signals,

D. control means including addressing means for controlling the storage of said time signals and said weight signals in said storage means, and further including signal processing means for selectively extracting said stored time and weight signals and generating display signals therefrom, said display signals being representative of the body weight of said person as a function of time, and

E. display means responsive to said display signals for displaying information representative of said body weight as a function of time,

wherein said display includes;

means for displaying a continuous line segment in a two dimensional field, where said line segment is single-valued in one of said dimensions, said one dimension being representative of time and said other dimension being representative of body weight, and

means responsive to said display signals to selectively control said line display means whereby said line segment includes points in said field representative of said sensed body weights at corresponding weight signal generation times.

5. A system according to claim 4 wherein said line segment displaying means is a cathode ray tube and associated drive networks.

6. A system according to claim 4 wherein said line display control means includes means to display the area in said field below said displayed line segment.

7. A system according to claim 4 wherein said line display control means includes means to display the area in said field above said displayed line segment.

8. A digital body weight scale system with historical display, comprising:

A. transducer including a force sensor and associated means for generating digital weight signals representative of the body weight of a person in sensed relation with said sensor,

B. data entry means for generating a digital time signal representative of a point in time associated with the generation of one of said weight signals,

C. storage means for storing said time signals and said weight signals,

D. control means including addressing means for controlling the storage of said time signals and said weight signals in said storage means, and further including signal processing means for selectively extracting said stored time and weight signals and generating display signals therefrom, said display signals being representative of the body weight of said person as a function of time, and

E. display means responsive to said display signals for displaying information representative of said body weight as a function of time,

wherein said display includes;

a rectangular array of selectively operative light reflective cells including a succession of m columns of cells, each cell being selectively operable in a reflective state and a non-reflective state with respect to incident light, wherein each column has n cells therein where m and n are integers, wherein the cells of each column in said succession are associated with a corresponding point of a succession of points in time, and each cell of a column is representative of a predetermined weight associated with the point in time for that column, and

means responsive to said display signals to selectively control at least one cell to be in its reflective state in each column having an associated point in time corresponding to the point in time associated with said generation of one of said weight signals, said one reflective state cell being representative of the body weight represented by that weight signal.

9. A system according to claim 8 wherein said selective control means includes means to control the cells in said columns below said one reflective state cell in said columns to be in their reflective state.

10. A system according to claim 8 wherein said selective control means includes means to control the cells in said columns above said one reflective state cell in said columns to be in their reflective state.
