Abstract: A hearing assistance device includes two transducers which react to a characteristic of an acoustic wave to capture data representative of the characteristic. The device is arranged so that each transducers is located adjacent a respective ear of a person wearing the device. A signal processor processes the data to provide relatively more emphasis of data representing a first sound source the person is facing over data representing a second sound source the person is not facing. At least one speaker utilizes the data to reproduce sounds to the person. An active noise reduction system provides a signal to the speaker for reducing an amount of ambient acoustic noise in the vicinity of the person that is heard by the person.

Abstract: An active suspension system for a vehicle including elements for developing and executing a trajectory plan responsive to the path on which the vehicle is traveling. The system may include a location system for locating the vehicle, and a system for retrieving a road profile corresponding to the vehicle location.

Abstract: An active wheel damper. An active suspension damps vertical displacement of an unsprung mass in a frequency range and reduces vertical displacement of a sprung mass in another frequency range.

Abstract: A method of distinguishing sound sources includes the step of transforming data, collected by at least two transducers which each react to a characteristic of an acoustic wave, into signals for each transducer location. The transducers are separated by a distance of less than about 70 mm or greater than about 90 mm. The signals are separated into a plurality of frequency bands for each transducer location. For each band a comparison is made of the relationship of the magnitudes of the signals for the transducer locations with a threshold value. A relative gain change is caused between those frequency bands whose magnitude relationship falls on one side of the threshold value and those frequency bands whose magnitude relationship falls on the other side of the threshold value. As such, sound sources are discriminated from each other based on their distance from the transducers.

Abstract: An audio reproduction system substantially fits the dynamic range of recorded and broadcast music (or other type of audio content) into a desired output dynamic range, bounded by the available dynamic range of the listening environment. In some scenarios the output dynamic range may be defined as a function of the ambient noise level present in the environment and the maximum output capabilities of audio system. A listener may adjust the desired prominence of the program with a user control, with foreground (louder and more dynamic) as one extreme and background (quieter and less dynamic) as the other extreme. A control to adjust prominence, when used to provide background reproduction, may reduce the average volume of a reproduced signal and fit the input signal dynamic range into a suitably smaller but desired output signal dynamic range.
