    • In an electrophysiology (EP) lab, a bedside interface device allows an EP physician to directly control various diagnostic and therapeutic systems, including an electro-anatomic mapping system. The bedside interface device can include a computer with wireless communication capability as well as a touch-responsive display panel and voice recognition. The bedside interface device can also be a hand-graspable wireless remote control device that is configured to detect motions or gestures made with the remote control by the physician, allowing the physician to directly interact with the mapping system. The bedside interface device can also be a motion capture camera configured to determine motion patterns of the physician's arms, legs, trunk, face and the like, which are defined in advance to correspond to commands for the mapping system. The bedside interface device may also include voice recognition capabilities to allow a physician to directly issue verbal commands to the mapping system.

    • The present invention is directed to the selective provision of interference canceled signal streams to demodulating fingers in a communication receiver. According to the present invention, potential interferer signal paths are identified. Signal streams having one or more potential interferer signals removed or canceled are created, and a correlation is performed to determine whether the strength of a desired signal path increased as a result. If the correlation indicates that the strength of a desired signal path was increased by the signal cancellation, the interference canceled signal stream is provided to the demodulation finger assigned to track the desired signal path. If the correlation determines that the strength of the desired signal path did not increase as a result of performing interference cancellation, the raw or a different interference canceled signal stream is provided to the demodulation finger.
    • 本发明涉及在通信接收机中选择性地提供干扰消除信号流来解调手指。 根据本发明,识别潜在的干扰信号路径。 产生具有去除或取消的一个或多个潜在干扰信号的信号流,并且执行相关性以确定所需信号路径的强度是否随之增加。 如果相关性指示所需信号路径的强度通过信号消除而增加,则将干扰消除信号流提供给被分配用于跟踪期望信号路径的解调手指。 如果相关性确定期望信号路径的强度作为执行干扰消除的结果没有增加,则原始或不同的干扰消除信号流被提供给解调手指。

    • The present invention provides systems and methods for interference matrix construction. Such an interference matrix may be used to generate a cancellation operator that when applied to a signal may substantially remove selected interfering signals. In one embodiment of the invention, a system comprises an interference selector configured for selecting one or more interferers for interference cancellation. The system also comprises a matrix generator communicatively coupled to the interference selector and configured for receiving selected interferers from the interference selector. The matrix generator is also configured for generating a matrix having one or more vectors, wherein each vector comprises elements of at least one of the selected interferers. Such an interference matrix and the subsequent generation of the cancellation operator may advantageously provide interference cancellation to systems employing CDMA (e.g., such as cdmaOne and cdma2000), WCDMA, Broadband CDMA, UMTS and GPS signals.
