US Patent:

20120162094, Jun 28, 2012

Filed:

Jan 25, 2011

Appl. No.:

13/013596

Inventors:

Joel C. Kent - Fremont CA, US
Selina Li - Sunnyvale CA, US

International Classification:

G06F 3/041

US Classification:

345173, 178 1803

Abstract:

A location of contact with a touch sensitive device is determined. Output signals associated with a plurality of electrodes such as formed on a single layer of the touch sensitive device are measured to identify a first electrode positioned at an approximate location of contact with the touch sensor. An output signal associated with a different electrode that is separated from the first electrode is measured to determine an undesired signal amount, such as due to deflection. An undesired single amount associated with the first electrode may be estimated based on the undesired signal amount measured at the other electrode. The signal amount measured at the first electrode is then compensated by the estimated undesired signal amount. The location of contact with the touch sensor is then determined based on the compensated signal amount.

Inventors:

Joel C. Kent - Fremont CA, US
Selina Li - Sunnyvale CA, US
Jong Yi - Hamilton NJ, US

International Classification:

G06F 3/044
G06F 3/041

US Classification:

345174, 345173

Abstract:

A location of contact with a touch sensitive device is determined. Values associated with each electrode of a plurality of electrodes formed on a single layer of the touch sensitive device are sampled. A determination is made as to whether a contact with the touch sensitive device has occurred. Values sampled subsequent to the contact are adjusted based on selected stored sampled values. A location of contact is then determined based on the adjusted values.
