Universal stylus

摘要

The present device provides for a universal stylus. The stylus emits a light incident upon a distal metallic object therein causing electrons on the metallic object to be ejected from the metallic object, resulting in a non-uniform electric field near the metallic object. When the metallic object is brought into close proximity of a capacitive touch-screen of a smartphone, tablet, kiosk, computer or other electronic device, the local disruption in the electric field surrounding the touch-screen is registered as a touch, in a similar manner as a human finger normally activates the touch-screen. In an embodiment, the device utilizes a light incident directly upon the electronic device, without the need for the light incident striking a metallic object.

主权项

1. An electronic stylus and a capacitive sensing touch-screen electronic device system comprising: an electronic stylus having a generally cylindrical housing having a first end and a second end; a touch-screen electronic device having an illuminating device located therein; a metallic object secured to and located near the first end of the generally cylindrical housing of the electronic stylus wherein the metallic object is capable of emitting a plurality of electrons when struck by a light incident generated by the illuminating device located within the touch-screen of the electronic device; wherein there is no physical permanent connection between the electronic stylus and the touch-screen electronic device having the illuminating device; wherein the illuminating device produces a light incident which strikes the metallic object and energizes the metallic object and causes the metallic object to eject electrons therein forming a non-uniform electric field near the metallic object; and wherein the non-uniform electric field created by the metallic object therein is detected by a capacitive sensing electronic touch-screen device and wherein the capacitive sensing electronic device may be operated and controlled by movement of the non-uniform electric field surrounding the metallic object.
