Balance control system for weight scales
View Patent ↗The present invention is directed to a weight scale having a balance control system that detects unequal load distribution to the scale's load sensors and produces an output signal that enables the user to re-distribute weight until a predetermined level of balance is achieved. Various load sensors are positioned in an array in the scale and are in communication with a controller that receives signals from the sensors indicative of relative load applied to each sensor. The controller generates a signal that is displayed or emitted to the user indicative of the position of the user's center of gravity relative to the sensors.
1. A scale for measuring the weight of an object, said scale comprising:
an upper surface;
a plurality of electronic sensors, each for sensing a load that is a portion of a total load applied to said upper surface of said scale by the object,
wherein the sum of the loads of said plurality of sensors equals the total load applied to said upper surface of said scale by the object; and
a plurality of feet, wherein each foot is positioned in a corner of said scale, wherein each of said plurality of sensors is located directly above a different one of said plurality of feet, and wherein each of said plurality of feet is movable relative to said upper surface, wherein said relative movement is in response to the load measured by said plurality of sensors.
2. The scale according to claim 1 , wherein said plurality of sensors are a plurality of strain gauges.
