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 and an undesired signal. 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.

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.

Abstract: A first communication unit transmits a first signal to a second communication device and concurrently processes the first signal in its receiver. A second communication unit transmits a second signal to the first communication device and concurrently processes the second signal in its receiver. Both communication units use the first and second signals to calculate time difference values that in turn may be used to calculate the distance between the first and second communication units.
