Abstract: A hand-held control device includes a housing including first and second housing pieces and a touch pad attached to an exterior surface of the first housing piece. The second housing piece defines a coupler well containing an electrical header. A speaker retention structure on an interior surface of the second housing piece includes an annular wall extending from an interior surface of the first housing piece and including a plurality of gaps at spaced intervals, and a resilient speaker retention finger extending from the interior surface of the first housing piece in each of the gaps. A cable connector assembly includes a coupler containing a socket, and a control cable electrically connected to the socket within the coupler. The coupler is sized and shaped to fill a coupler well in the housing so that the socket is connectable to the electrical header in the coupler well.

Abstract: A method of forming an article from a plurality of fiber bundles comprising the steps of providing at least one supply of fiber bundles, the fiber bundles having bonding fibers, supplying the fiber bundles to an injector, sequentially injecting fiber bundles from the fiber bundle feed assembly to predetermined positions within a mold member, heating the fiber bundles within the mold member to facilitate the adhesion of bonding fibers to, in turn, integrate the fiber bundle into an article, and, removing the fiber bundles from the mold member. An article and a system for forming same is likewise disclosed.

Abstract: A cushioning assembly (i.e., for bedding, chairs, sofas, couches among other surfaces which require or benefit from cushioning) which includes a plurality of springs and fiber bundles. The plurality of springs are disposed at predetermined locations. The fiber bundles are cooperatively associated with the plurality of springs. The fiber bundles are disposed into association with the plurality of springs. Subsequently, they are integrated through a heating process with the plurality of springs and each other.

Abstract: Spatialization of soundfields is accomplished by filtering audio signals using filters having unvarying frequency response characteristics and amplifying signals using amplifier gains adapted in response to signals representing sound source location and/or listener position. The filters are derived using a singular value decomposition process which finds the best set of component impulse responses to approximate a given target set of impulse responses corresponding to head related transfer functions. Efficient implementations for rendering reflection effects, air absorption losses and other ambient effects, and for spatializing multiple sound sources and/or generating multiple output signals are disclosed.

Abstract: A method and apparatus is capable of accurately deriving acoustic transfer functions such as head-related transfer functions (HRTF) at low cost. Various aspects of the invention include constraining the reflection geometry of a measurement system to facilitate removal of reflection effects, establishing ambient noise level and ambient reverberation time to calibrate test signals, generating soundfields using Golay code test signals, invalidating measurements by detecting test subject movement and short-duration ambient sounds, deriving distance and/or interaural time difference (ITD) using minimum-phase forms of impulse responses, and deriving equalized HRTF suitable for use in acoustic displays without knowing output or input transducer acoustical properties. Spatial resampling of derived HRTF and spectral shaping of test signals are discussed.
