Abstract: A touch sensitive device that detects the occurrence of an electrostatic discharge event on the device by analyzing an acquired touch image for characteristics associated with the occurrence of an ESD event is provided. An acquired touch image is analyzed for characteristics that differentiate it from a touch image generated by a user input and are correlated with an expected touch image generated by an ESD event.

Abstract: The use of multiple stimulation signals having one or more frequencies and one or more phases to generate an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have one or more mixers. Each mixer in the sense channel can utilize a circuit capable generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of one or more selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the one or more mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the one or more selected frequencies. After all steps have been completed, the demodulated signals from the one or more mixers can be used in calculations to determine an image of touch for the touch sensor panel at each of the one or more frequencies.

Abstract: Negative pixel compensation in a touch sensor panel is disclosed. The panel can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the panel. To do so, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and compute a composite image from the captured image and the reconstructed image to replace the captured image. In addition or alternatively, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and replace the captured image with the reconstructed image.
Abstract translation: 公开了触摸传感器面板中的负像素补偿。 由于接触面板的物体接地不良，面板可以补偿触摸信号输出中的负像素效应。 为了这样做，面板可以重构捕获的触摸图像以去除指示负像素效应的负像素值，并从捕获的图像和重构图像计算合成图像以替换捕获的图像。 另外或替代地，面板可以重建捕获的触摸图像以去除指示负像素效应的负像素值，并用重构图像替换所捕获的图像。

Abstract: A low power can for device wake up and unlock is disclosed. The low power scan can include one or more algorithms used to detect a sequence and/or one or more gestures to wake up a processor and unlock the device. A sequence and/or one or more gestures can be determined by a microcontroller and/or by a separate hardware component. The microcontroller can send a notification to the processor and/or switch the device from an idle to an active state. By detecting the sequence and gestures in the microcontroller before waking up the processor, the battery life can be extended. In some examples, the microcontroller can determine if the sequence and gestures are due to water splashes, water film, and/or noise. In such examples, the microcontroller can reject the touch without waking up the processor, and further extending the battery life of the device.
