Abstract

Certain example embodiments of this invention relate to a display device. The display device may comprise a display capable of displaying at least one design drawing. At least one storage location may be capable of storing at least one design drawing to be displayed. Display programmed logic circuitry may be capable of causing the display to display the at least one design drawing based at least in part on one or more scale parameters, such that the at least one design drawing is displayed on the display so as to allow measurements to be taken directly from the display. The displayed design drawing may be altered by means of a user interface to adjust, for example, the scale, viewable area, rotation, etc. The display device may portable, and it may useful for deployment in, for example, the engineering, real estate, mapping, surveying, construction, and other fields.

Claims

1. A display device, comprising:

a display for displaying at least one design drawing;

at least one storage location for storing the at least one design drawing to be displayed on the display; and

,

display programmed logic circuitry causing the display to display the at least one design drawing based at least in part on one or more scale parameters so that the at least one design drawing is displayed on the display so as to allow measurements to be taken directly from the display.

2. The display device of claim 1, further comprising a user interface for permitting instructions to be provided to the display programmed logic circuitry to adjust the display.

3. The display device of claim 2, wherein the user interface is capable of receiving user input to change the at least one design drawing in terms of scale, viewable area, and/or rotation.

4. The display device of claim 1, wherein the at least one design drawing comprises one or more of a specification, technical schematics, map, schematic, landscape, survey, and/or architectural drawing.

5. The display device of claim 1, wherein the one or more scale parameters comprise one or more of:

display size, display scale, display resolution, actual design size of the design drawing, and/or design drawing scale.

6. The display device of claim 1, wherein the display is a slow refresh display.

7. The display device of claim 1, wherein the display is a bi-stable display.

8. The display device of claim 1, wherein the at least one storage location is located on a removable or non-removable computer-readable storage medium.

9. The display device of claim 8, wherein the removable computer-readable storage medium is a flash card, SD card, or USB device.

10. The display device of claim 1, further comprising a port for connection with a device to transmit one or more design drawings.

11. A method of displaying at least one design drawing on the display of a device, the method comprising:

receiving the at least one design drawing;

determining scale parameters including at least the size of the display, scale at which the design drawing is to be displayed, and scale data of the at least one design drawing;

calculating display parameters; and

,

displaying the design drawing on the display based at least in part on the display parameters such that the at least one design drawing is displayed on the display so as to allow measurements to be taken directly from the display.

12. The method of claim 11, further comprising:

receiving input from a user interface to adjust the display;

re-calculating the display parameters based on the input; and

,

updating the display based at least in part on the re-calculated display parameters.

13. The method of claim 12, wherein the input corresponds to a change in the at least one design drawing in terms of scale, viewable area, and/or rotation.

14. The method of claim 11, wherein the at least one design drawing is a specification, technical schematic, map, schematic, landscape, survey, and/or architectural drawing.

15. The method of claim 11, further comprising displaying the scale used by the display.

16. A computer-readable storage medium, comprising:

at least one design drawing; and

,

scale parameters for each said design drawing;

wherein based at least in part on the at least one design drawing and the scale parameters, a device capable of reading the computer-readable storage medium is capable of causing a display of the device to display the at least one design drawing such that measurements can be taken directly from the display.

17. The computer-readable storage medium of claim 16, wherein the computer-readable storage medium is a flash card, SD card, or USB device.

18. The computer-readable storage medium of claim 16, wherein the computer-readable storage medium is updatable.
