Abstract

An apparatus, such as a medical equipment product, has an integral user input device with a plurality of manually actuatable keys representing a predetermined item of data or function specific to the associated product. The data is entered or function carried out by actuating the keys of the device. Visually perceptible indicia are associated with a selected plurality of the keys that are indicative of the item of data or function represented by the keys. E-ink may be used for to form the indicia. The visually perceptible indicia for the keys are established in a given language and can be altered from those of the given language to those in another language. This permits operation of the product with keys labeled in differing languages. The user input device may also have status indicators for the apparatus and/or input device with changeable indicia.

Claims

1. Apparatus comprising:

a product;

user input device integral with said product and having a plurality of keys and indicators, each of a plurality of keys of the device representing a predetermined item of data or function for the product, the data being entered or function being carried out by actuating the keys of the device;

a plurality of manually actuatable elements forming the keys of the device;

a plurality of elements forming visually perceptible indicators of the device;

indicia means associated with at least a selected plurality of said keys and/or indicators for providing a visually perceptible indicium for each of the selected keys indicative of the item of data or function represented by the keys and/or a visually perceptible indicium for the nature of each of the indicators;

means for establishing the visually perceptible indicia in a form for use in a given language; and

means for altering indicia for the selected plurality of keys and/or indicators from a form suitable for use in one language to a form suitable for use in another language.

2. The apparatus of claim 1 wherein said indicia means provide indicia comprising an alpha-numeric character or characters or comprise other character or characters.

3. The apparatus of claim 1 wherein said indicia means is applied to the keys of said device.

4. The apparatus of claim 3 wherein indicia means are individually applied to the keys of said device.

5. The apparatus of claim 3 wherein said indicia means is applied to the keys as a unitary structure.

6. The apparatus of claim 5 wherein said indicia means is applied as a membrane.

7. The apparatus of claim 1 wherein said indicia means provides the indicia proximate to said keys or indicators.

8. The apparatus of claim 7 wherein said indicia means forms a template about keys or indicators of said device.

9. The apparatus of claim 1 wherein said indicia means comprises electronic-ink means.

10. The apparatus of claim 9 wherein said electronic ink means comprises an electronic ink film.

11. The apparatus of claim 10 wherein said electronic ink film is placed on said keys.

12. The apparatus of claim 10 wherein said electronic ink film covers a plurality of said keys.

13. The apparatus of claim 10 wherein said electronic ink film is placed in proximity to said keys or indicators.

14. The apparatus of claim 13 wherein said keys bear permanent indicia.

15. The apparatus of claim 1 wherein said indicia means is electrically operable and said indicia means maintains said indicia in visibly perceptible form when the electrical power is off.

16. The apparatus of claim 9 wherein said electronic ink means is electrically operable and maintains said indicia in visually perceptible form when the electrical power is off.

17. The apparatus of claim 1 wherein said indicia means comprise liquid crystal display means.

18. The apparatus of claim 17 wherein said liquid crystal display means is positioned proximate to said keys or indicators.

19. The apparatus of claim 18 wherein said keys bear permanent indicia.

20. The apparatus of claim 17 wherein said liquid crystal display means defines keys of said device and wherein said liquid crystal display means is covered with a touch screen.

21. The apparatus of claim 1 wherein said means for altering said indicia comprise part of said product.

22. The apparatus of claim 1 wherein said user input device comprises a keyboard.

23. The apparatus of claim 1 wherein said product comprises medical equipment.

24. The apparatus of claim 23 wherein said means for altering said indicia comprise part of said product.

25. An improved apparatus comprising:

a medical equipment product;

a keyboard integral with said product and having a plurality of keys and indicators, each of the plurality of keys of the keyboard representing a predetermined item of data or function for the medical equipment product, the data being entered or function being carried out by actuating the keys of the keyboard;

indicia means associated with at least a selected plurality of said keys and/or indicators for providing a visually perceptible indicium for each of the selected keys indicative of the item of data or function represented by the keys and a visually perceptible indicium for the nature of each of the indicators;

means for establishing the visually perceptible indicia in a character or characters for use in a given language; and

means for altering indicia for the selected plurality of keys and/or indicators from a form suitable for use in one language to a form suitable for use in another language, thereby to permit operation of the medical equipment product with keys and indicators labeled in different languages.
