Abstract

A multifunctional writing apparatus includes a writing device and a stylus operable to control a capacitive touch screen display device. The multifunctional apparatus includes an electrically conducting body having a first end and a second end. The first end includes a writing device such as a pen or pencil which allows a user to write on a paper or another type of media. The second end of the body comprises an electrically conductive portion which, when in contact with a capacitive based touch screen display device, allows a user to make a capacitive coupling and operate the touch screen display device.

Claims

1. A writing device and stylus combination apparatus comprising:

a body, the body comprising a first end and a second end;

the first end comprising a conductive material and the second end comprising a writing device and wherein the conductive material forms an enlarged or flared end for making limited contact with a touch screen display and wherein the limited contact comprises a surface contact area of ranging from 4-6 mm².

2. The apparatus of claim 1, wherein the writing device comprises a media ink cartridge.

3. The apparatus of claim 2, wherein the ink cartridge is adapted to write on a plurality of surfaces, to write upside down, or to write between temperatures of −

45°

C., to +200°

C.

4. The apparatus of claim 1, wherein the conductive material is comprised of one material selected from the group consisting of rubber, silicone, foam, fabric, PVC, and leather.

5. The apparatus of claim 1, wherein the conductive material is comprised of a material having a conductivity of below 10⁵ Ohm/cm².

6. The apparatus of claim 1, wherein the conductive material is comprised of a material having a density between 0.5 and 3.1 lbs/ft³.

7. The apparatus of claim 1, wherein the conductive material is comprised of a material having the property of not scratching a surface of a touch screen display when it is contact with the touch screen display.

8. The apparatus of claim 1, wherein the apparatus is adapted to allow a user to control a touch screen device with the first end, and write on a paper medium with the second end.

9. The apparatus of claim 1, wherein said first end is adapted to control a capacitive touch screen device when the conductive material of the first end is touched to the screen of the touch screen device and second end is adapted to write on a paper medium.

10. The apparatus of claim 1, wherein the conductive material of the first end comprises an angled tip, thereby allowing a user to control a capacitive touch screen device with the apparatus contacting the touch screen device at an angle less than 90 degrees.

14. The apparatus of claim 1, wherein the second end comprises at least one of a mechanical lead pencil, a ball point pen, or a writing device.

15. The apparatus of claim 1, wherein the conductive material is affixed to the first end of the apparatus by a conductive adhesive bond.

16. The apparatus of claim 15 wherein said adhesive bond is formed from one of the adhesives selected from the group consisting of a conductive epoxy or a conductive bonding resin.

17. The apparatus of claim 1, wherein the body is comprised of a conductive material, or comprises a conductive coating on the outer surface of a non-conductive material to provide capacitive coupling to the touch screen device.

18. The apparatus of claim 1 wherein the body comprises a first portion that is rotatable relative to a second portion of the body, whereby rotation of the first portion to the second portion serves to eject a tip of the writing device from the second end of the body.

11. A multifunctional writing apparatus comprising:

a body comprising a first end and a second end, and the first end comprising a writing member; and

a removable cap enclosing the first end, and wherein the cap comprises a tip, and a conductive material disposed on the tip for interfacing with a capacitive based touch screen.

12. The apparatus of claim 11, wherein the cap mechanically attaches on the first end and the second end of the apparatus.

13. The apparatus of claim 12 wherein the second end comprises a conductive material and wherein the apparatus is adapted to allow user to remove the cap and use the cap and the second end of the body simultaneously to control gesture capabilities of a multi-touch touch screen display device.

19. A writing device and stylus combination apparatus comprising:

a body, the body comprising a first portion and second portion rotatable to the first portion;

the first portion comprising a cavity for holding at least a stylet and a writing device wherein said stylet comprises a conductive material adapted to capacitively couple with a touch screen display.
