Abstract: An element of an automatic gain control system that automatically calibrates a Composite Gain vs Ambient Noise look-up table responsive to user zone gain inputs at various ambient noise levels. The table is a graph of adjacent (horizontally or diagonally) data points (nodes) mapping ambient noise to composite gain. Three algorithmic rules determine position changes of the nodes responsive to zone gain inputs. A curve may be fit to an arrangement of adjacent nodes. The curve, or the interpolated table value, is used with an ambient noise input to determine the current composite gain. The element may be used with many traditional ANC systems. Once calibrated over the full range of ambient noises in the user's space, the ANC system may never need further user zone gain inputs.

Abstract: An apparatus instantiating a method for computing automatic noise compensation gain with an adaptive filter that receives ambient sound and source audio, down samples ambient sound and source audio, and filters the down sampled ambient sound and source audio to compute an RMS noise estimate from which a gain is determined. The present invention features highly efficient computations, as sampling rates are significantly lower. The present invention keeps audio data secure by transmitting only the mean-square audio levels instead of the audio itself.

Abstract: Embodiments of the present invention may provide a step, rock guard, handyman jack storage and even jack lift point system that can be made for most 4×4 vehicles. One product may resolve individual problems that may become apparent once a lift kit and larger wheels are installed on a 4×4 vehicle. Products can be made to fit two-door Jeeps, four-door Jeeps, Trucks, SUV's, or the like.

Abstract: A frequency-domain peak detector is configured to detect harmonic content of a digital input signal. An equalizer-based feedback synthesizer is configured to generate simulated feedback at a specified frequency by filtering existing content of the digital input signal at the specified frequency. A tone-based feedback synthesizer is configured to generate simulated feedback at the specified frequency by generating a tone at the specified frequency. Feedback selection logic is configured to determine the specified frequency at which to generate simulated feedback based on the harmonic content, and whether to utilize the equalizer-based feedback synthesizer or the tone-based feedback synthesizer to generate simulated feedback at the specified frequency.

Abstract: A feedback suppression system for detecting a feedback peak may include a controller configured to identity at least one peak of an audio input signal that includes audio data and acoustic feedback, apply at least one signature to the at least one peak, determine a response of the at least one peak to the at least one signature, identify the at least one peak as a feedback peak in response to the determined response, and set a notch filter at the identified frequency to eliminate the acoustic feedback of the audio input signal.

Abstract: A vacuum cleaner comprises a hair collection assembly having a hair collection element adapted to collection hair from a surface. The hair collection assembly can be mounted to the cleaning head of the vacuum cleaner for movement between a use position in which the hair collection element is in contact with the surface and a second position in which the hair collection element in spaced from the surface. The hair collection element can further be configured to collect hair from the surface when the cleaning head is moved in a first direction and to not collect hair from the surface when the cleaning head is moved in a second direction. A method of removing hair from a surface is also described.

Abstract: Systems and methods for displaying maps and points such as points corresponding to points of interest on displayed maps are disclosed, the display of the points being dynamically and automatically altered in response to alterations in the displayed maps. The systems and methods include providing a map view and points therefor in response to a user request, as well as supplying preloaded map records for map views and points records so that the records and points are ready for display in the event the user selects actions to change the displayed view, such as by panning or zooming. For instance, the systems and methods may include AJAX techniques to download a library of points, as well as map records, a subset of which is initially displayed and a second subset is displayed in response to the user actions.

The plurality of projections comprise at least one row of aligned projections having a non-circular face extending opposite to the top portion of the brush head. The brush is disclosed for removing pet hairs from fabrics.
