Systems And Methods For Providing Enhanced Touch Sensing
US Patent:
2011019, Aug 11, 2011
Filed:
Feb 3, 2011
Appl. No.:
13/020613
Inventors:
John Walley - Ladera Ranch CA, US
Robert Lukas - Vancouver, CA
David Sobel - Los Altos CA, US

Assignee:
BROADCOM CORPORATION - IRVINE CA
International Classification:
G06F 3/041
US Classification:
345173
Abstract:
Provided are systems and methods for providing enhanced touch sensing. One system providing enhanced touch sensing includes a multi-mode touch screen and a processor configured to apply at least one test signal to a sense element of the multi-mode touch screen, detect at least one return signal from the sense element, and then determine a relative position of an object corresponding to the at least one return signal, the multi-mode touch screen being capable of sensing the first object using first and second detection modes. One multi-mode touch screen comprises a multi-mode multi-touch touch screen. One processor is configured to apply an adaptive test signal to a sense element of a touch screen.
Waterproof Baseline Tracking In Capacitive Touch Controllers
US Patent:
2013017, Jul 11, 2013
Filed:
Mar 2, 2012
Appl. No.:
13/410844
Inventors:
Tianhao Li - Tustin CA, US

Assignee:
BROADCOM CORPORATION - Irvine CA
International Classification:
G06F 3/044
US Classification:
345174
Abstract:
A method for a touch panel control circuit includes stimulating a touch panel and receiving signals responsive to the stimulating. Based on the received signals, water or another contaminant may be determined to be present on the touch panel. While the contaminant is present on the touch panel, a wet baseline mode of operation in which a different baseline value is used to detect a touch condition for the touch panel. When the contaminant is removed, operation returns to a dry baseline mode.
Fast Touch Detection In A Mutual Capacitive Touch System
US Patent:
2013017, Jul 11, 2013
Filed:
Mar 8, 2012

International Classification:

G06F 3/041
G06F 3/041
US Classification:
345174, 345173
Abstract:
A method for touch detection in a touch panel display includes entering a low power touch detection mode and intermittently stimulating the touch panel display with signals to determine if any touch event occurs without locating the touch event on the touch panel. If a touch event is detected, a full scan mode is entered to locate the touch event on the touch panel. This provides both faster touch detection and lower power operation for the touch panel display and controller circuit.
