    Abstract: A signal processing device includes a single moment prediction and correction engine configured to receive a signal including a target signal, and to execute a single-moment filter, based on a current measurement sample of the signal and a model of the target signal, to obtain a single-moment state estimate and a single-moment state estimate error covariance for the target signal, a covariance renormalizer configured to determine a multi-moment state estimate error covariance for the target signal based on a prior single-moment state estimate error covariance, corresponding to a sample prior to the current measurement sample, and the single-moment state estimate error covariance, and a multi-moment prediction and correction engine configured to execute a multi-moment filtering extension based on the current measurement sample and the multi-moment state estimate error covariance to obtain a multi-moment state estimate, and further configured to determine an estimate for the target signal based on the multi-moment state estimate.

    Abstract: In a recognition method, movement characteristics of an object are determined based on sensor information; image information of the object is determined based on the sensor information; and one or more gesture recognition operations are performed based on the movement characteristics and the image information to generate gesture recognition information. The recognition method may further include determining one or more physical characteristics of the object based on the image information; performing one or more physical characteristic pattern recognition operations based on the one or more physical characteristics to generate pattern recognition information; and generating a recognition output signal based on the gesture recognition information and the pattern recognition information.

    Abstract: In some embodiments, the invention includes a system having a clock recovery circuitry to receive a data signal and a reference clock signal and in response thereto to produce an in phase clock signal which is in phase with the data signal and mirrors frequency changes in the data signal, wherein the data signal has embedded clock information and a varying frequency. The system also includes a receiving gate to receive the data signal and the in phase clock signal and to gate the data signal to produce a gated data signal in response to the in phase clock signal. Other embodiments are described and claimed.
