Proximity and multi-touch sensor detection and demodulation
First Claim
1. A first electronic device, comprising:
- a first sensor array input device configured to detect a presence of a first object and generate one or more signals to enable a first feature; and
a subsystem communicatively coupled to the first sensor array input device and capable of communication with a second electronic device;
wherein the first electronic device is configurable for enabling the first feature when a second object is detected by a second sensor array input device on the second electronic device during an absence of the first object at the first sensor array input 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.
