Abstract: Disclosed is a video controlled beam steering mechanism for an adaptive filter in a sensor array system that receives input from a target and applies an averaging filter and appropriately steers the beam. An adaptive filter is then used if the SNR of the output of the averaging filter reaches a threshold.

Abstract: A miniature microphone enclosure is provided for use with a wireless headset. The microphone enclosure provides superior noise and wind cancellation without any circuitry. Two sound ports and wind suppression material help minimize any noise attributable to wind or air. Moreover the microphone enclosure has a directivity such that the microphone does not have to be placed directly in front of a user's mouth.

Abstract: 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 preferences. The intensity, frequency, and light patterns of the LEDs may change when a threshold level is reached.

Abstract: 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 front end and a back end enclosed by the microphone isolator; an windscreen placed in front of the microphone and internally behind the voice port; and an acoustical port to permit a pressure gradient noise porting placed at the back end of the microphone and internally behind the noise port.

Abstract: 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 noise, and for converting the first acoustic sound to a first signal, and second microphone means arranged at a predetermined angle .phi. in close proximity with respect to the first microphone means for receiving a second acoustic sound composed of substantially the background noise and for converting the second acoustic sound to a second signal. The first and second microphones are connected to a differential amplifier means of the noise cancellation apparatus so as to obtain a signal representing substantially speech. The amplifier means is for receiving acoustic sounds from each microphone and has a first terminal and a second terminal, wherein the second terminal is grounded.

Abstract: 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 back end enclosed by the microphone isolator; an acoustical tube having an acoustical waveguide connected to the microphone isolator for channeling an input signal; a chest piece having a sound diaphragm pickup for receiving the input sound and noise signal connected to acoustic tube to permit a pressure gradient noise porting placed at the back end of the microphone and internally behind the noise port.

Abstract: 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 transmission, and signal processing means for canceling the noise signals to create an inverted anti-noise signal within an acoustical waveguide located adjacent to the earphone of headset. The method for reducing noise according to this invention is provided by an open loop circuit allowing the input audio signal from an operator or caller to be transmitted to the user's ear without the disturbance of unwanted ambient noise. The method provides adjustments to the gain and/or phase of a noise signal for canceling the noise component detected, within an acoustical waveguide to produce a quiet zone for the desired audio speech to be transmitted.
