    摘要： Systems and methods are disclosed for determining a touch position from data received from a touch panel. In one implementation, an apparatus for processing a touch input signal includes a processor that may be configured for parallel processing, a touch device, a memory, operably connected to the processor, and configured to store processor instructions. The processor instructions can configure the processor to receive a plurality of data points corresponding to a plurality of touch events on the touch device, determine a center of mass estimate from the plurality of data points, determine a search radius of center of mass estimate, and determine an optimal touch point position based on the center of mass estimate and the search radius using the processor.

    摘要： Systems, methods, and devices for adjusting the position of a touch input are contained herein. In one aspect, a method of correcting the position of a touch input near the edge of a touch screen and across the touch screen is disclosed. The method includes receiving a touch input, determining a position of a centroid corresponding to the touch input, determining a bias based on the position and a bias model, and determining whether to adjust the position based on the bias.

    摘要： A client device presents streaming media and includes a stream manager, a request accelerator, and a source component coupled to the stream manager and the request accelerator for determining which requests to make. A rate selection process can make rate decisions so that the buffer is filled when it is low, avoiding erratically changing rates and can choose the correct steady rate quickly. Multimedia download strategies can be used for HTTP that allow for accurate rate estimations, achieving link capacity even if network delays and packet loss rates are high, achieving timely delivery of the stream, and achieving relatively steady download rates with little short term variability. A receiver might use multiple HTTP connections, decompose media requests into smaller chunk requests, synchronize the connections using TCP flow control mechanisms, and request data in bursts. In addition, the receiver might use an HTTP pipelining process to keep the connections busy.
