ABSTRACT:
A weighing scale capable of weighing articles in a rapid and accurate fashion. The tray of the scale is supported by at least one spring and becomes vertically displaced in proportion to the weight of an article placed thereon. A voice coil is used to bias the tray to its original position, and the weight of the article is determined by measuring the current in the voice coil.
