Various methods and systems are provided for a drift-compensated force measurement. In one example, a method includes obtaining a single output voltage measurement from a strain gauge of an infant scale, the single output voltage reflective of a weight applied to the scale; obtaining a voltage measurement across each of four resistors of the strain gauge to determine four separate voltage measurements and determining a drift voltage based on the four separate voltage measurements; and outputting a corrected weight value determined based on a difference between the single output voltage and the drift voltage

It is recognized that an offset is added to a measurement value shown by a weight scale. In a case where a measurement value, shown by a body weight scale, has decreased from a first reference value by more than a first threshold, an offset determining section determines whether or not a difference between the measurement value and a second reference value is greater than a second threshold. In a case where the offset determining section determines that the difference between the measurement value and the second reference value is greater than the second threshold, the offset determining section stores the measurement value as a candidate second reference value.

An electronic scale includes a display unit for digitally displaying the weight of a load on a weighing dish, a tare subtraction key, a display control unit for controlling the display on the display unit and a memory for memorizing a zero adjustment range. The display control unit displays on the display unit a tare subtraction prompt display for prompting to push the tare subtraction key when the measurement value of the load increases over the upper limit of the zero adjustment range.

A cutting force analyser is provided, comprising weighing means adapted to determine the weight of an object and force applied to the object; a record of a force threshold for cutting the object; and indicating means. The analyser is formed to use the weighing means to differentiate between the weight of the object and cutting force applied to it, to compare the cutting force with the force threshold, and to use the indicating means to communicate how the force compares with the threshold.

A combination scale is provided that includes a combinatorial computation unit and two operation modes; a normal operation mode, and a corrective operation mode in which correction values are decided. The correction values are for use in correcting errors of measured weight values calculated from weight signals of weight sensors. In the normal operation mode, the combinatorial computation unit corrects the measured weight values using the correction values decided in the corrective operation mode. Then, the combinatorial computation unit executes combinatorial computations based on the corrected measured weight values.

An apparatus and method for automatically removing dough pieces from overhead dough proffer, weighing the dough pieces and reinserting them back in to the process stream. The weight information is analyzed to determine whether it represents the weight of pieces or the empty scale weight, and may be used to provide a signal proportional to the weight of a dough portion, or group of dough potions in order to automatically adjust the rate at which dough is fed to the dividing mechanism, thereby increasing or decreasing the dough piece weights to maintain the desired amount of dough per piece.
