D371133 Boom microphone headset June 25, 1996
8150054 Adaptive filter in a sensor array system April 3, 2012
Disclosed is a steerable sensor array that receives input from a target and applies an averaging filter. An adaptive filter is then used if the SNR of the output of the averaging filter reaches a threshold.
7319762 Headset with flashing light emitting diodes January 15, 2008
A headphone system is provided with two earbud headphones and a control module, each fitted with a plurality of light emitting diodes (LEDs). The LEDs may be of many different colors and flash to the beat of the music. Patterns, colors, and intensity may be adjusted based on a user's
6594367 Super directional beamforming design and implementation July 15, 2003
A sensor array receiving system which incorporates one or more filters that are capable of adaptive and/or fixed operation. The filters are defined by a multiple of coefficients and the coefficients are set so as to maximize the signal to noise ratio of the receiving array's output. In o
6483923 System and method for adaptive interference cancelling November 19, 2002
An adaptive system and method for reducing interference in a signal received from an array of sensors. Adaptive filters are used to generate cancelling signals that closely approximate the interference present in the received signal. The adaptive filter weights are converted into the
6377637 Sub-band exponential smoothing noise canceling system April 23, 2002
A noise canceling method and apparatus for canceling noise by time domain processing sub-bands of a digital input signal. The input signal is divided into a number of frequency-limited time-domain sub-bands. Each sub-band is then individually processed to cancel noise present in the
6363345 System, method and apparatus for cancelling noise March 26, 2002
A threshold detector precisely detects the positions of the noise elements, even within continuous speech segments, by determining whether frequency spectrum elements, or bins, of the input signal are within a threshold set according to current and future minimum values of the frequency
6332028 Dual-processing interference cancelling system and method December 18, 2001
A dual-processing interference cancelling system and method for processing a broadband input in a computationally efficient manner. Dual processing divides the input into higher and lower frequency bands and applies adaptive filter processing to the lower frequency band while applying
6198693 System and method for finding the direction of a wave source using an array of sensors March 6, 2001
A system and method for finding the direction of a wave source using an array of sensors. The system includes a sensor array for measuring waves from the wave source, an approximate-direction finder for finding the approximate direction of the wave source in terms of a sensor pair from
6178248 Dual-processing interference cancelling system and method January 23, 2001
A dual-processing interference cancelling system and method for processing a broadband input in a computationally efficient manner. Dual processing divides the input into higher and lower frequency bands and applies adaptive filter processing to the lower frequency band while applying
6108415 Noise cancelling acoustical improvement to a communications device August 22, 2000
A cellular telephone for reducing background noise comprising a housing having a receiver portion and a speaker portion; the receiver portion having a voice port and a noise port; a microphone isolator located within the receiver portion; at least one noise canceling microphone having a
6061456 Noise cancellation apparatus May 9, 2000
Disclosed is a transducer for use in a noise cancellation apparatus for reducing background noise. The transducer includes a housing having first microphone means for receiving a first acoustic sound composed of speech originating from an operator operating the apparatus and background n
5909495 Noise canceling improvement to stethoscope June 1, 1999
A stethoscope for reducing background noise comprising a housing having a receiver portion and an audio output means; the receiver portion having a plurality of noise ports; a microphone isolator located within the receiver portion; a noise canceling microphone having a front end and a
5825897 Noise cancellation apparatus October 20, 1998
This invention relates to a method and an apparatus for reducing ambient noise for use with a headset or a boom headset attached to a boom microphone device or the like. The apparatus can include a sensor microphone to detect a background noise signal, a desired input audio transmiss
5673325 Noise cancellation apparatus September 30, 1997
Apparatus for reducing acoustic background noise for use with a telephone handset or a boom microphone device or a boom headset or the like. The apparatus includes first and second microphones which are arranged such that the first microphone receives a desired speech input and the b
5381473 Noise cancellation apparatus January 10, 1995
Apparatus for reducing acoustic background noise for use with a telephone handset or a boom microphone device or the like. The apparatus includes first and second microphones which are arranged such that the first microphone receives a desired speech input and the background noise pr
5251263 Adaptive noise cancellation and speech enhancement system and apparatus therefor October 5, 1993
Disclosed is a headset apparatus for use in an intercommunications system, the headset suppressing both noise in the vicinity of a transducer delivering sound to an operator's ear and in outgoing speech from the operator.
