All digital and adjustable scale device

Claim 2

An adjustable electronic scale comprising: at least one load cell for output of an analog loading signal responsive to a pressure force applied thereto; at least one A/D converter connected to the at least one load cell and converting the analog loading signal of the load cell into a digital loading signal provided at an output thereof; a single-chip microcomputer connected to the output of the A/D converter and receiving the digital loading signal therefrom, the single-chip microcomputer manipulating the digital loading signal to output an output signal; and a control circuit having an input connected to the single-chip microcomputer and receiving the output signal therefrom for further processing and output of signals representing a value of force loading corresponding to the pressure force, the control circuit having an input for a user to input commands for controlling the single-chip microcomputer through the control circuit for initiation of four-corner balancing, adjustment, calibration and self-testing.

Claim 3

The adjustable electronic scale as in claim 1 , wherein the A/D converter and the single-chip microcomputer are housed within a connection box.

Claim 4

The adjustable electronic scale as in claim 1 , wherein the control circuit is housed in a controller main body.

Claim 5

The adjustable electronic scale as in claim 1 , wherein the control circuit further comprises a microcomputer unit, a keyboard connected to an input of the microcomputer, and a display coupled to an output of the microcomputer for display of the value of force loading, the microcomputer unit being connected to an external device through an interface unit.

Claim 6

The adjustable electronic scale as in claim 4 , wherein the control circuit is housed in a controller main body and the keyboard is arranged on the controller main body.

Claim 7

An adjustable electronic scale comprising: a plurality of load cells, each of said load cells outputting an analog loading signal responsive to a respective pressure force applied thereto; a plurality of A/D converters respectively connected to said plurality of load cells, each of said A/D converters converting a respective analog loading signal of a corresponding load cell into a digital loading signal provided at an output thereof; a single-chip microcomputer having a plurality of inputs respectively connected to said outputs of said A/D converters and receiving said digital loading signals therefrom, the single-chip microcomputer manipulating the digital loading signals to output an output signal; and a control circuit having an input connected to the single-chip microcomputer and receiving the output signal therefrom for further processing and output of signals representing a value of force loading relating to said pressure forces applied to said plurality of load cells, the control circuit having an input for a user to input commands for controlling the single-chip microcomputer through the control circuit for initiation of four-corner balancing, adjustment, calibration and self-testing.

Claim 8

An adjustable electronic scale comprising: a plurality of load cells, each of said load cells outputting an analog loading signal responsive to a respective pressure force applied thereto; a plurality of A/D converters respectively connected to said plurality of load cells, each of said A/D converters converting a respective analog loading signal of a corresponding load cell into a digital loading signal provided at an output thereof; a single-chip microcomputer having a plurality of inputs respectively connected to said outputs of said A/D converters and receiving said digital loading signals therefrom, the single-chip microcomputer manipulating the digital loading signals to output an output signal; and a control circuit having an input connected to the single-chip microcomputer and receiving the output signal therefrom for further processing and output of signals representing a value of force loading relating to said pressure forces applied to said plurality of load cells, the control circuit having an input for a user to input commands for controlling the single-chip microcomputer through the control circuit for initiation of four-corner balancing, adjustment, calibration and self-testing.
