Latest Patents
Xiang Zhu's latest patents focus on interference removal in pointing device locating systems. The first patent describes an apparatus and method for determining the location of a pointing device in the vicinity of a set of receivers that can receive one or more locating signals transmitted through a medium. The method involves receiving a signal that includes both a locating signal and an interfering signal. It also includes determining an estimated interference signal indicative of the interfering signal, calculating the difference between the received signal and the estimated interference signal, and using this difference to compute the location of the pointing device on a surface near the receivers. One version of the method utilizes a separate receiver to determine the estimated interference signal, while another version relies on the received signal at a time when no locating signal is expected. An adaptive filter is employed to compute the estimated interference signal.
