PROXIMITY AND MULTI-TOUCH SENSOR DETECTION AND DEMODULATION
First Claim
1. A first electronic device, comprising:
- a first sensor panel configured to detect a presence of a first object; and
a subsystem communicatively coupled to the first sensor panel and capable of communication with a second electronic device;
wherein the first electronic device is configurable for switching states based on a detection of a second object by a second sensor panel on the second electronic device.

Abstract
The use of one or more proximity sensors in combination with one or more touch sensors in a multi-touch panel to detect the presence of a finger, body part or other object and control or trigger one or more functions in accordance with an “image” of touch provided by the sensor outputs is disclosed. In some embodiments, one or more infrared (IR) proximity sensors can be driven with a specific stimulation frequency and emit IR light from one or more areas, which can in some embodiments correspond to one or more multi-touch sensor “pixel” locations. The reflected IR signal, if any, can be demodulated using synchronous demodulation. In some embodiments, both physical interfaces (touch and proximity sensors) can be connected to analog channels in the same electrical core.
