| 20100156525 | Method and System for Tuning Precision Continuous-Time Filters - Described embodiments provide a method for calibrating a continuous-time filter having at least one adjustable parameter. A square-wave signal is filtered by a continuous-time filter having a cutoff frequency less than fs. The filtered signal is quantized at the rate fs. An N-point Fourier transform is performed of the quantized signal into N real output values and N imaginary output values. At least one of the real output values are accumulated to form a real output signal and at least one of the imaginary output values are accumulated to form an imaginary output signal. The real and imaginary output signals are summed to form an output signal, which is then squared. The squared output signal is compared to a comparison value. At least one parameter of the continuous-time filter is adjusted based upon the comparison. The steps are repeated until the squared output signal is approximately the comparison value. | 06-24-2010 |

| 20100067621 | Feed Forward Detector for Pattern Dependent Noise Prediction - Various embodiments of the present invention provide systems and methods for processing data. As one example, a circuit is disclosed that includes a digital input signal that is provided to a pre-detector that detects an estimated pattern in the digital input signal. In addition, the digital input signal is provided to a summation element that subtracts the estimated pattern from the digital input signal to yield a noise estimate. The noise estimate is provided to a data dependent noise prediction filter that is statically tuned to detect a highly correlated noise pattern, and provides a filtered noise estimate. In some cases, the circuit further includes a post-detector that performs a data detection process on the digital input signal reduced by the filtered noise estimate. | 03-18-2010 |
| 20100067628 | Adaptive Pattern Dependent Noise Prediction on a Feed Forward Noise Estimate - Various embodiments of the present invention provide systems and methods for processing data. As one example, a circuit is disclosed that includes a pre-detector that detects an estimated pattern in a digital input signal, and a summation element that subtracts the estimated pattern from the digital input signal to yield a noise estimate. The circuit further includes a data dependent noise prediction filter that is adaptively tuned to detect a noise pattern, and that filters the noise estimate to provide a filtered noise estimate. | 03-18-2010 |
| 20120107921 | MODEL BASED CONTROLS FOR USE WITH BIOREACTORS - Embodiments of the present invention include model-based controls to control photobioreactor operation and the growth of algae for use as a biofuels feedstock. In some embodiments, the model-based control can accounts for future conditions such as weather, product pricing, customer demands and/or other variables to operate the reactors in a manner that optimizes product revenues, minimizes costs or energy, maximizes photosynthetic or energy balance efficiency, and/or any combination of the aforementioned factors. | 05-03-2012 |

| 20120107792 | SYSTEMS AND METHODS FOR DELIVERY OF GASES TO ALGAL CULTURES - Photobioreactors according to embodiments of the present invention deliver nutrient gas intermittently to the photobioreactor media. In some embodiments, one or more gases are delivered according to a duty cycle or timing pattern. According to some embodiments, algae is grown in a photobioreactor using intermittent introduction of carbon dioxide. In other embodiments, carbon dioxide is supplied to algae grown in a photobioreactor in whole or in part from a head space above the media of the photobioreactor. | 05-03-2012 |

| 20090088630 | Surgical navigation tracker, system and method - An adapter can be easily used to assist a surgical navigation system to determine the effector axis or the effector plane of a surgical device. The adapter has a body with a geometrical feature, the geometrical feature has a known relation with a navigation tracker device that can be attached to the adapter. When the adapter is held against a surgical device in a non-fixed manner, the effector axis or the effector plane of the device can be tracked by the surgical navigation system. The method includes a calibration method to determine the known relation between the effector axis or the effector plane and the location of the navigation tracker. | 04-02-2009 |
