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.
