Communication Between Touch-Panel Devices
First Claim
1. A touch-panel device comprising:
- a processor;
a detect electrode; and
a controller coupled to the processor, the controller including a detection circuit coupled to the detect electrode, wherein the controller is configured to receive a first signal from the detect electrode with the detection circuit, detect a modulation in the received first signal, and determine information associated with the detected modulation, wherein the detected modulation in the first signal is indicative of a physical proximity between the touch-panel device and another touch-panel device, wherein the first signal is provided by a touch panel of the other touch-panel device.

Abstract
Technologies described herein generally relate to communications between electronic systems. Each electronic system includes a touch-panel device that may be positioned in proximity to one another such that the near field emissions of the touch-panel devices interact with one another. The touch-panel devices can be adapted to sense one another based on these near field emissions. Once detected, the touch-panel devices can be configured to establish a communication channel to communicate information between one another via modulated near field emissions. Such exchanged information may include identification information, network addresses, security keys, and so forth. The exchanged information may be used for discovery or pairing between the touch-panel devices. The technology presented herein can support an intuitive user experience and improved security over traditional wireless pairing approaches.

12. A computer storage medium having computer-executable instructions stored thereon for a method which, when executed by a computing device, adapt the computing device to establish communications utilizing a touch-panel device, the method comprising:
-
modulating information in a first signal; coupling the first signal to a drive electrode of the touch-panel device such that the drive electrode generates a first electromagnetic field in response to the first signal; receiving a second signal from a detect electrode of the touch-panel device, wherein the second signal is responsive to a second electromagnetic field associated with provided by a touch panel of another touch-panel device; and establishing a communications channel between the touch-panel device and the other touch-panel device using the first signal and the second signal. - View Dependent Claims (13, 14, 15, 16)

17. A computer-implemented method for communicating between a first touch-panel device and a second touch-panel device, the method comprising:
-
receiving, at the first touch-panel device, a first signal from a first electrode coupled to a first panel of the first touch-panel device, wherein the first signal is provided by a second touch panel of the second touch-panel device; detecting, at the first touch-panel device, a modulation in the first signal, wherein the modulation indicates a communication from the second touch-panel device; and determining, at the first touch-panel device, information associated with the modulation. - View Dependent Claims (18, 19, 20)
