Abstract: Berührungserfassung (touch sensing) kann unter Verwendung von Master/Slave-Berührungssteuereinheiten erreicht werden, die Ansteuerungssignale (drive signals) an eine Berührungsoberfläche übertragen, und Erfassungssignale (sense signals) einschließlich Überlagerungen verarbeiten, welche aus Master/Slave-Ansteuerungssignalen resultieren. Der Master/Slave kann unterschiedliche Sätze von Leitungen der Berührungsoberfläche ansteuern bzw. erfassen. Eine Kommunikationsverbindung zwischen Master/Slave kann durch Übertragen eines Taktsignals (clock signal) zwischen Master/Slave, Übertragen eines Befehls einschließlich Sequenzinformation an den Slave, und Initiieren einer Kommunikationssequenz von dem Taktsignal und der Sequenzinformation hergestellt werden. Der Slave kann Kommunikationen vom/zum Master während ersten/zweiten Teilen der Kommunikationssequenz empfangen/übertragen. Berührungserfassungsoperationen können zwischen Master/Slave synchronisiert werden, durch Übertragen eines Befehls einschließlich Phasenausrichtungsinformation (phase alignment information) vom Master zum Slave, und Erzeugen von Slave-Taktsignalen basierend auf dem Taktsignal und der Phasenausrichtungsinformation, so dass Erfassungssignalverarbeitung durch Master-Taktsignale in Phase mit der Erfassungssignalverarbeitung durch die Slave-Taktsignale sind.

Abstract: MASTER/SLAVE CONTROL OF TOUCH SENSING Abstract Touch sensing can be accomplished using master/slave touch controllers that transmit drive 5 signals to a touch surface and process sense signals including superpositions resulting from master/slave drive signals. The master/slave can drive and sense different sets of lines, respectively, of the touch surface. A communication link between master/slave can be established by transmitting a clock signal between master/slave, transmitting a command including sequence information to the slave, and initiating a communication sequence from the 10 clock signal and sequence information. The slave can receive/transmit communications from/to the master during first/second portions of the communication sequence, respectively. Touch sensing operations can be synchronized between master/slave by transmitting a command including phase alignment information from master to slave, and generating slave clock signals based on the clock signal and the phase alignment information, such that sense signal processing 15 by master clock signals are in-phase with sense signal processing by slave clock signals.

Abstract: Embodiments of the invention include an IC that includes a core used for ordinary operation and a thin power circuit. The thin power circuit can be configured to use very little power. The IC can also include a digital interface and a connection 5 thereto. The IC can initiate transition to low power mode during which the core and various I/O pads can be shut down. However, the thin power circuit can be kept powered up. The thin power circuit can monitor the digital interface for a predefined wake up signal. When the wake up signal is detected, the thin power circuit can power up the core and any powered down I/O pads. The thin power circuit can also 10 include a dedicated power on reset (POR) cell. This POR cell can be distinct than other POR cells used for the IC and can be specifically designed to for efficient operation.

Abstract: A system and method for autonomously scanning a sensor panel device, such as a multi-touch panel, is disclosed. In one embodiment, the system and method disables a sensor panel processor after a first predetermined amount of time has elapsed without the sensor panel device sensing any events. One or more system clocks can also be disabled to conserve power. While the processor and one or more system clocks are disabled, the sensor panel device can periodically autonomously scan the sensor panel for touch activity. Accordingly, if one or more results from the autonomous scans exceed a threshold, the sensor panel device re-enables the processor and one or more clocks to actively scan the sensor panel. If the threshold is not exceeded, then the sensor panel device continues to periodically autonomously scan the sensor panel without intervention from the processor. Furthermore, the sensor panel device can periodically perform calibration functions to account for any drift that may be present in the system.
