Body weight measuring apparatus
First Claim
1. A body weight measuring apparatus, comprising sensing means responsive to the body weight of a person being weighed on said apparatus to provide a measured displacement value representing the actual body weight, signal generating means operatively connected to said sensing means for generating an electrical signal representative of said actual body weight, setting means for providing fixed conditioning data including at least a reference signal value associated with the height of said person being weighed, signal evaluating means operatively connected to said setting means for determining a standard range of body weight values correlated to said conditioning data, means operatively connected to said signal generating means and to said signal evaluating means for determining the relativity of said measured actual body weight value relative to said standard body weight range values, and display means responsive to an output from said relativity determining means for displaying the result of said determining and correlating, wherein said signal evaluating means for determining a standard range of body weight values comprise first means responsive to said fixed conditioning data to evaluate a standard body weight value out of said standard range of body weight values and second means responsive to said first means and thus to said standard body weight value for evaluating an extremity value of said standard body weight range, said first means comprise memory means for storing a list of a plurality of standard body weight values in the form of electrical signals as classified in accordance with said conditioning data, said apparatus further comprising means responsive to said setting means and operatively connected to said memory means for addressing said list of standard body weight values for selectively reading out the corresponding standard body weight value to provide a respective electrical signal.

Abstract
A body weight measuring apparatus, comprising a scale mechanism adapted to be displaced in accordance with the body weight of a person on the scale mechanism, means for converting the displacement amount of said scale mechanism into an electrical pulse train the number of which pulses is associated with said displacement amount, a counter for counting the number of pulses of said pulse train to provide a data associated with said body weight by way of a count value, and a display for displaying said body weight in a digital manner, wherein various conditioning data, such as the height, sex, age, nationality and the like of a person being measured is set, a standard body weight is evaluated in accordance with the set conditioning data, said standard body weight and said measured body weight are compared to evaluate the difference body weight, which is displayed by means of said display, an upper limit and/or lower limit for defining a desirable standard range of body weight determinable by said conditioning data is evaluated with said standard body weight, and said standard range and the measured body weight are compared to determine whether said measured body weight is "normal weight" , "overweight", or "underweight", which determination is displayed by individual lamps, if desired, said standard body weight being also displayed by said display.
