Electronic weighing apparatus

An electronic weighing apparatus employing a strain gauge type load cell and digital display, particularly applicable as a live body scale for babies and other live load articles whose movement changes the displayed body or article weight, comprising article placement means for placement of an article being weighed, analog signal generating means operatively coupled to said article placement means and responsive to the weight of an article being placed on said article placement means for generating an analog signal representative of the measured weight of said article, digital data generating means responsive to said analog signal from said analog signal generating means for generating digital data associated with said analog signal and thus the weight of said article, digital data storing means operatively coupled to said digital data generating means for storing said digital data, digital data display means responsive to said digital data stored in said digital data storing means for sequentially displaying in a digital manner the measured weight of said article, stable state detecting means operatively coupled to at least one of said analog generating means and said digital data generating means and responsive to at least one of said analog signal and said digital data for sampling said digital data at predetermined intervals of time, comparing the digital data from successive intervals, and determining that said article placement means has reached for the first time a substantially stable state after said article is placed on said article placement means, display maintaining means responsive to the output of said stable state detecting means for arresting the sequential display of digital data and for maintaining the data being displayed by said display means at said weighed value obtained when said stable state was determined in spite of movement of the body or article being weighed causing a variation in the measured weight sampled by said stable state detecting means, detecting means operatively coupled to at least one of said analog signal generating means and said digital data generating means for detecting that at least one of said analog signal and said digital data has become smaller than a predetermined value after said stable state detected output has been determined, and releasing means responsive to the detected output of said detecting means for releasing said display maintaining state by said display maintaining means.
