Abstract:
A Decision-Feedback Equalizer (DFE) includes a Maximum Likelihood Sequence Estimator (MLSE) for estimating a symbol sequence. The DFE also includes a signal level decoder, and a delay line having a first plurality of taps being connected to the output of the signal level decoder, and a second plurality of taps being connected to the output of the MLSE. Furthermore, the DFE has an error signal generator having a first input connected to the input of the signal level decoder, and a second input connected to the output of the signal level decoder for adjusting coefficients of the taps. The symbol delay line has been split into two sections with the output of the MLSE being fed to part of the delay line. Because symbols in the delay line are adjusted with the coefficients and fedback to the signal level decoder, the output of the MLSE is able to correct symbols whenever its output is available. In such a symbol updating approach, error propagation in the delay line is avoided during an error event.

Abstract:
A Global Navigation Satellite System (GNSS) receiver and associated method capable of tracking weak GNSS signals from a plurality of GNSS satellites. In a preferred embodiment, code and carrier tracking loops are initially closed around the code phase, carrier frequency, and data bit edge estimates handed over from an acquisition mode. In subsequent tracking, early, prompt, and late copies of the code replica are correlated with the incoming signal. The prompt correlations are coherently integrated over an extended updating interval for data bit edge and sign estimation as well as for carrier phase and frequency error discrimination whereas the early and late correlations are used for code error discrimination. Code delay and carrier phase and frequency errors are used to update the code and carrier tracking loop filters. Together with data bits, they form observables of a GNSS signal's time and frequency parameters for timing and position fixing.

US Classification:
428800, 427127
Abstract:
A perpendicular magnetic recording layer may include a hard granular layer, an exchange break layer formed on the hard granular layer, and a soft granular layer formed on the exchange break layer. In some embodiments, the exchange break layer may consist essentially of ruthenium. In some embodiments, the perpendicular magnetic recording layer may include n magnetic layers and n−1 exchange break layers, where n is greater than or equal to three, and where the n−1 exchange break layers alternate with the n magnetic layers in the magnetic recording layer.

Abstract:
A virtual vertical surface in a three-dimensional space that represents a physical room may be detected. Responsive to a first user input gesture, movement of a virtual object within the three-dimensional space may be displayed. The movement may be to a first location in which a portion of the virtual object intersects a portion of the virtual vertical surface. A virtual vertical surface designator may be displayed corresponding to the virtual vertical surface based at least in part on the portion of the virtual object intersecting the portion of the virtual vertical surface. Upon determining that a second user input gesture meets or exceeds a movement threshold, movement of the three-dimensional object from the first location to a second location within the three-dimensional space may be displayed. The second location may appear beyond the virtual vertical surface.

Abstract:
An improved analytics system dynamically generates, integrates, and deploys multiple models for use related to a particular user and/or user segment. The integrated model analytics system can deploy a set of models specifically identified for a user from a group of models related to the service. This set of models can be used to provide recommendations for the user related to content of the service. As the user continues to interact with the service, the integrated model analytics system can dynamically update multiple models from the set of models based on real-time user interactions. These updated models can be used to generate updated recommendations for the user that can be used to dynamically update content presented to the user. In addition, this updated model can be used when providing recommendations for users in other user segments.
