摘要： Asymmetric scanning logic implements asymmetric panel scanning by scanning some rows on a touch panel more frequently than other rows. Note that although an entire row at a time may be driven, if only particular pixels in the row are of interest (e.g., included in any region of interest for focused asymmetric scanning), then circuitry may power down the receivers for the columns in which the pixels exist to save power. The asymmetric scanning logic facilitates focused attention to specific areas of interest on the touch panel, to compensate, for example, for high noise or low signal strength in those areas of interest.
摘要翻译：非对称扫描逻辑通过比其他行更频繁地扫描触摸面板上的一些行来实现非对称面板扫描。注意，虽然可以驱动一次的整行，但是如果行中的特定像素是感兴趣的（例如，包括在用于聚焦的非对称扫描的任何感兴趣的区域中），则电路可以将其中的列的接收器断电存在像素以节省电力。非对称扫描逻辑有助于将注意力集中在触摸面板上的特定感兴趣区域，以补偿例如在感兴趣的区域中的高噪声或低信号强度。

摘要： Control circuitry for a touch panel includes a touch panel interface, a memory comprising touch positioning logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the touch positioning logic is executed, to perform selected processing of the touch panel, including scanning a touch panel and determining a touch panel blob resulting from a touch, obtaining blob characteristics of the touch panel blob, and determining a position of the blob relative to the touch panel based on the blob characteristics. The blob characteristics can be adjusted to more accurately position the blob in circumstances where the blob is located near the edge of the touch panel, is in close proximity to another blob, or when the touch panel has variation in the received signal noise.

摘要： 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.

摘要： Operating a remote control to identify a user by receiving touch pad input from at least one touch sensitive element of the remote control that has a plurality of touch sensitive elements. The touch pad input corresponds to the user's touch of at least some of the plurality of touch sensitive elements. The touch pad input is at least partially processed by processing circuitry of the remote control and transmitted to a multimedia system console via a communications interface of the remote control for processing of the at least partially processed touch pad input to identify the user via pattern recognition. At least partially processing the touch pad input can be by identifying at least one finger orientation, at least one finger spacing, at least one finger width, a plurality of finger knuckle/joint locations, and/or a plurality of finger lengths based upon the touch pad input.
