  • Publication number: 20250097633
    Abstract: A playback device includes (i) at least one first transducer, (ii) at least one second transducer, (iii) a housing, and (iv) an acoustic resistive mesh filter. The housing includes (i) a first cavity having a first volume, the first cavity housing the at least one first transducer, (ii) a second cavity having a second volume, the second cavity in fluid communication with the at least one second transducer, and (iii) a vent fluidly coupling the first cavity and the second cavity, the vent defining an aperture having an open area. The acoustic resistive mesh filter is coupled to the vent and positioned to cover the open area of the aperture and thereby resist acoustic flow through the vent.

  • Publication number: 20060262938
    Abstract: Adapting an audio response addresses perceptual effects of an interfering signal, such as of a residual ambient noise or other interference in an earpiece of a headphone. In one aspect, an input audio signal is presented substantially unmodified when it is at levels substantially above the interfering signal and is compressed when at or below the level of the interfering signal. The approach can make use of a measured level of an acoustic signal, for example, within an earpiece of a headset, and use the measured level in conjunction with the level of an input audio signal to determine compression characteristics without requiring separation of an interfering signal present in the monitored acoustic signal from a component related to the input audio signal. In another aspect, presentation characteristics of an input audio signal are determined to reduce distraction from an interfering signal, such as from a background conversation.

  • Publication number: 20050248031
    Abstract: An electronic circuit can be produced by placing an electrically conductive compressible circuit bump on a circuit electrode of a mounting surface of first and second circuit devices, such as an integrated circuit and a base substrate. One or more auxiliary bumps can also be placed on one or both of the mounting surfaces of the circuit devices. During mounting, the first circuit device can be positioned over the second circuit device with the circuit bumps connecting circuit contacts on the two mounting surfaces. Pressure can be applied so that the circuit bumps and the auxiliary bumps are compressed between the chip and the base device sufficiently for adhering at least the circuit bumps to the circuit contacts.

  • Publication number: 20050203058
    Abstract: The present invention relates to stable compositions comprising ?- and ?-chitosan and derivatives thereof for controlled absorption and/or coagulation of fluids from a wound or bleeding site. The invention further provides methods for preparing these stable compositions and articles of manufacture comprising these compositions. The stable compositions of the present invention are particularly useful in methods for treatment of open wounds or bleeding sites in a mammal using disposable medical and personal care articles that require controlled absorption, hemostasis, and tensile strength.

  • Patent number: 4128065
    Abstract: An incinerator/combustor, comprising an elongated combustion chamber surrounded by an afterburner which is in turn surrounded by a housing, the afterburner and housing being coaxial with, and cooperating to provide redundant heating for, the combustion chamber, is disclosed. The combustion chamber is generally cylindrical with a horizontal axis, one end being adapted to receive materials to be burned. An ash chamber is spaced from the other end of the combustion chamber to define a circumferential opening which serves as an exhaust outlet. The two chambers are relatively movable to permit the flow of exhaust gases to be controlled. Air under controlled pressure is introduced to the combustion chamber to produce a cyclonic flow to enhance burning. A fuel supply may be provided to initiate combustion, but the system is designed to require no fuel other than the material being incinerated during normal continuous operation.
