Handheld electronic scale with touch screen
First Claim
1. A portable electronic weighing device comprising:
- a platform on which an object is placed for weighing;
weighing circuitry in communication with said platform for weighing objects placed on said platform to provide weight data thereof;
a display having a first and second display area, said first display area for digital display of weight data of said object, and wherein said display further comprises an input device for receiving input from a user;
calculating circuitry responsive to said input device and said weighing circuitry for providing output data, said output data displayed on said second display area;
wherein said weight data is selectively transferred to said calculating circuitry through said input device by the user upon a single command without re-entering the weight data.

Abstract
The hand held scale of the present invention comprises a rectangular casing with a weighing platform, for supporting items to be weighed, a touch display screen, for displaying the weight of the objects and controlling the functions for the scale, and the electronic components for controlling such. The scale is preferably an electronic scale, where downward forces on the weighing platform are sensed by a transducer which produces an electrical signal indicative of weight. The visual display is touch screen. The touch screen display controls the calculator of the scale, which can also perform arithmetic calculations on the results of the weighing function. The calculator function can be used to perform price calculation based on unit price and the weight of the object. For example, the weight of the object can be transferred to the calculator function by depressing the weight on the touch screen display. The weight can then be multiplied by the unit price to determine the total price. If the weight is changed, the total price figure will also be updated instantly.
