The controller comprises several components: a first input for a reference signal indicative of a noise level; a second input for receiving an error signal indicative of a remnant noise level; an output for providing a noise cancellation signal; a fixed feedback controller for processing the error signal; a fixed feed-forward controller for processing the reference signal; and an adaptive feed-forward controller having a digital adaptive finite impulse response filter arranged for operation on the reference signal the error signal. | 07-17-2014 |
20150063589 | METHOD, APPARATUS, AND MANUFACTURE OF ADAPTIVE NULL BEAMFORMING FOR A TWO-MICROPHONE ARRAY - A method, apparatus, and manufacture of beamforming is provided. Adaptive null beamforming is performed for signals from first and second microphones of a two-microphone array. The signals from the microphones are decomposed into subbands. Beamforming weights are evaluated and adaptively updated over time based, at least in part, on the direction of arrival and distance of the target signal. The beamforming weights are applied to the subbands at each updated time interval. Each subband is then combined. | 03-05-2015 |

20160026402 | SYSTEM AND METHOD FOR PROVIDING CONSISTENT, RELIABLE, AND PREDICTABLE PERFORMANCE IN A STORAGE DEVICE - The solution described here is a method to provide consistent performance in a storage device. A performance manager module is implemented to measure the time interval in which a command takes to be completed. In case the time interval is longer than a certain threshold, the difference is annotated and used on the consecutive commands within a programmable time window. This time window can be a regular time interval e.g. every second. In case the time interval is shorter than a threshold, the control module delays sending the command completion to the host until the threshold value is reached. The delay is adjusted based on the credit annotation due to commands that took longer than the time interval to be completed in order to compensate for commands that took longer than the threshold to complete, during a certain time window. | 01-28-2016 |
