Abstract
A weight scale system is for measuring the weight of an object, which includes a bed section, a vertical separator actuator and a controller. The bed section includes a lower-platform, an upper-platform and weight sensor assemblies located on the lower-platform, each includes at least one weight sensor. The bed section further includes at least one vertical-separator. The vertical-separator actuator is coupled with the vertical-separator and with the controller. The controller is coupled with the weight sensors. The controller directs the vertical-separator actuator to operate the bed section in at least two modes, a referencing mode in which the vertical-separator detaches the upper-platform from the weight sensor assemblies, thereby enabling referencing the weight sensors, and a weighing mode, in which the vertical separator re-attaches the upper-platform with the weight sensor assemblies, such that the weight associated with the upper-platform is fully applied on the weight sensors.
