Automatic weight and measures computing device and method
First Claim
1. An automatic weight and measures computing device comprising:
- a storage unit for storing a plurality of operational formulas, each operational formula being composed of at least two parameters and at least one logical operator;
an input device comprising;
a set of number buttons for inputting at least one number;
a set of symbol buttons for inputting at least one logical operator;
a set of selection buttons for selecting an operational formula; and
a confirmation button for confirming input data;
a display unit comprising;
a value display area for displaying values; and
a formula display area for displaying the selected operational formula; and
a control unit for executing a mathematical operational formula;
wherein the automatic weight and measures computing device is characterized in that the input unit inputs values corresponding to parameters according to the selected operational formula, and then the control unit provides an operational result according to the selected operational formula and the input values and displays the operational result in the value display area.

Abstract
An automatic weight and measures computing device and method includes: a storage unit, an input device, an input device, a display device and a control device. The storage unit is used for storing a plurality of operational formulas. When an input signal of a selected operational formula is received, the selected operational formula is displayed on the display unit. The input unit inputs values corresponding to parameters according to the selected operational formula, and then the control unit provides an operational result according to the selected operational formula and the input values and displays the operational result in the value display area. The present invention can also be combined with a measuring tool to directly read the measurement value from the measuring tool as an input value.
