    Abstract: A lost or stolen computing device is recovered. A trusted server is requested to locate the computing device. The trusted server requests coarse location information from the computing device, and the computing device reports its coarse location. The trusted server then requests that the computing device transmit wireless local area networks signal so that it may be recovered.

    Abstract: Correcting a signal offset may include observing a finite duration signal yn that comprises a representation of a mixture of a desired signal that may include data of interest, and an undesired signal based on interference of an external interference source. The undesired signal may include an offset component which may be modeled as comprising a step function u defined by unknown step function parameters. The unknown step function parameters may be estimated using, for example, a maximum likelihood method. Thereafter, yn may be corrected based on the estimated step function parameters.
