Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic device comprising: a first input device configured to detect a presence of an object; a second input device capable of switching between a normal power mode and a reduced power mode; and a processor in communication with the first input device and the second input device and configured to switch the second input device to the reduced power mode based on a detection of the presence of the object by the first input device.…
