Abstract

A system for acquiring and displaying data in a measurement process includes a local display unit enabled for wireless data reception, and a measuring tool for acquiring measurement data, the tool being enabled for wireless data transmission. The system is characterized in that the acquired data is transmitted from the measuring tool to the local display unit and displayed thereon.

Claims

1. A system for acquiring and displaying data in a measurement process, comprising:

a local display unit enabled for wireless data reception; and

a measuring tool for acquiring measurement data, the tool enabled for wireless data transmission;

characterized in that the acquired data is transmitted from the measuring tool to the local display unit and displayed thereon.

2. The system of claim 1 wherein the wireless data reception and transmission is conducted over a radio frequency connection, an infrared connection, or an ultrasonic connection.

3. The system of claim 1 wherein the wireless data reception and transmission is carried over a radio frequency connection and the band is the industrial scientific and medical (ISM) band.

4. The system of claim 1 wherein the local display unit is magnetized on a portion thereof for convenient mounting on a metal display surface.

5. The system of claim 1 wherein the local display unit is a calculator with an existing data input port enabled to receive the measurement data through a plug-in wireless adapter.

6. The system of claim 1 wherein the local display unit is a calculator with an internal wireless chip and circuitry for reception of the measurement data.

7. The system of claim 1 wherein the measuring tool is one of a micrometer, a caliper, a bore gauge, a dial indicator, an inclinometer, a protractor, a level, or a drop indicator having internal wireless chipset and circuitry enabling wireless data transmission.

8. The system of claim 1 wherein the measuring tool is one of a micrometer, a caliper, a bore gauge, a dial indicator, an inclinometer, a protractor, a level, or a drop indicator having an existing output data port enabled to transmit the measurement data through a plug in wireless adapter.

9. The system of claim 1 wherein the local display unit has calculative capabilities adapted to perform calculations using received measurement data as one or more variables in a calculation.

10. The system of claim 1 wherein fabrication involves mounting one or more work pieces to a machine tool and fabricating one or more features thereon the work piece features fabricated subject to measurement while mounted.

11. The system of claim 1 used in machine-assisted production.

12. The system of claim 1 further comprising additional measuring tools adapted to communicate to a single local display unit.

13. The system of claim 12 wherein each additional tool is physically adapted for communication with the local display unit as required using a modular adapter.

14. The system of claim 1 wherein the local display unit and measuring tool use frequency hopping to manage communication.

31. The system of claim 3 wherein the wireless protocol used is Bluetooth™

or Zigby™

.

32. The system of claim 1 wherein the measurement tool is a tool adapted to monitor resistance of a strain gauge and to record differences in resistance caused by deflection of a leaf spring supporting the strain gauge.

33. The system of claim 32 wherein the leaf spring supports more than one strain gauge.

15. A wireless communication adapter for enabling a measuring tool to transmit measured data to a local display unit comprising:

a chipset and circuitry for enabling wireless transmission of measurement data;

a power source; and

a connector for plugging the adapter to a port on the tool.

16. The wireless communication adapter of claim 15 wherein the power source is a battery cell.

17. The wireless communication adapter of claim 15 wherein the chipset includes a memory device.

18. The wireless communication adapter of claim 15 wherein the chipset includes receive-circuitry in addition to transmit-circuitry.

19. The wireless communication adapter of claim 15 wherein the port on the tool is a statistical process control port.

20. The wireless communication adapter of claim 15 wherein the port on the tool is a universal serial bus port.

21. The wireless communication adapter of claim 15 wherein the connector includes a power pin and a command pin for deriving power from the tool and for sending commands to the tool through the port on the tool.

22. The wireless communication adapter of claim 21 wherein the port on the tool is a statistical process control port.

23. A method for displaying data measured from a work piece by a measuring tool, comprising steps of:

(a) positioning the measurement tool to take a measurement of a feature of the work piece;

(b) recording the measurement data;

(c) transmitting the acquired data wirelessly to a local display; and

(d) displaying the data on the local display.

24. The method of claim 23 wherein in step (a) the measurement data is acquired from a feature of a work piece mounted in a machine tool.

25. The method of claim 23 wherein in step (a) the tool position renders the display or readable face of the tool not visible to an operator of the tool.

26. The method of claim 23 wherein in step (c) the transmitting step causes a mode shift from a power conservation mode or sleep mode to an active wireless transmission mode.

27. The method of claim 23 wherein in step (c) transmitting the data occurs repeatedly over one or more channels for a predetermined and timed sequence.

28. The method of claim 23 further comprising a step (e) for acknowledgement of transmission success, the acknowledgement sent back to the tool.

29. The method of claim 23 wherein the local display is one of a liquid crystal display or a light emitting diode display capable of numeric display capability, graphic display capability, or both numeric and graphic display capability.

30. The method of claim 23 further comprising a step for using the received data as a variable in a calculative sequence.
