Abstract: A model predictive controller (MPC) for predictive control of nonlinear processes utilizing an EKF (Extended Kalman Filter) and a nominal trajectory generator. The nominal trajectory generator includes another instance of EKF, a linear corrector, and a time-varying deviation model. A nominal control trajectory can be predicted and an optimal solution for the time-varying deviation model can be computed based on an approximation of a system inverse known as signal de-convolution. The EKF can be utilized to estimate a current process state by supplying a measured output and to predict a future nominal trajectory by supplying a reference output. A Kalman smoother can also be utilized for the signal de-convolution in order to obtain enhanced trajectory estimates.

Abstract: Methods and apparatus for a MEMS sensor package are provided. In one embodiment, a MEMS sensor package comprises a MEMS sensor; a sensor body permeable to gas leakage at a first leak rate; a backfill gas that pressurizes the sensor body to a backfill pressure; wherein the backfill pressure provides a dampening of the MEMS sensor; and wherein the backfill pressure is set such than any increase in pressure within the sensor body due to gas leakage will not cause a deviation in a Q value of the MEMS sensor beyond a predefined range for at least a specified design service life for the MEMS sensor package.

Abstract: A system for aligning data is provided. The system comprises a demultiplexing component adapted to bifurcate a double data rate (DDR) data stream into first and second single data rate (SDR) data streams, a delay architecture adapted to generate delayed SDR data streams from the SDR data streams, a logic circuit adapted to analyze the SDR data streams and delayed SDR data streams to detect a predetermined bit pattern conveyed in the DDR data stream and to indicate detection of the predetermined bit pattern, and a data aligning component adapted to determine the number of intervening bits between occurrences of the predetermined bit pattern and to frame the intervening bits, thereby producing aligned data.
