Title: Web velocity modulator

Granted: 2010-06-22
Abstract: A process and apparatus related to a workstation adjacent to a traveling web including a device for intermittently performing an operation affecting the web. An important application involves ultrasonically welding multiple layers of a traveling web. First and second rollers on opposite sides of the workstation are simultaneously shifted in a direction counter to the machine direction each time a bonding force is applied. The overall running speed in the machine remains at a constant velocity due to the resultant festooning effect and thus the dwell time for bonding is increased. Thus the effective operating speed of processed having finite limits may be increased at least 33%. The first and second rollers are eccentrically rotationally mounted, respectively, on third and fourth hollow rollers which are provided with eccentrically positioned hollow cylindrical openings which, in turn, are mounted, respectively, on shafts positioned perpendicularly to the machine direction. Shifting of the rollers is effected by simultaneous rotation of the rollers. Preferably, the first and second rollers are driven synchronously in a first rotational direction and the third and fourth rollers are driven synchronously in the opposite rotational direction.

Abstract: This invention relates to a new type of reflective optical element made of a fluid that responds to a force if subjected to a magnetic field. As a consequence, one can impose any shape one wants to the reflecting surface by generating an appropriate magnetic field geometry with permanent magnets, electromagnets or a combination of permanent magnets and electromagnets, or the like. A preferred embodiment uses a ferromagnetic fluid made of water containing ferromagnetic nanoparticles. Liquid ferromagnetic surfaces thus obtained were successfully shaped using magnetic fields. In another preferred embodiment, to modify the reflectivity of the optical element, a reflective layer, such as a nano-engineered silver reflecting surface, is deposited on the surface of the magnetically sensitive fluid. The surface of the reflecting layer can therefore be warped by applying a magnetic field to the fluid. Coated or uncoated magnetically deformable liquid surfaces with reflective layers allows one to make inexpensive and versatile high-quality reflecting mirrors having complex shapes. The shapes of the reflecting surfaces can be changed within short time periods by changing the shapes of the magnetic fields.

Title: Method and apparatus for transmitting an audio stream having additional payload in a hidden sub-channel
Inventor: DING HEPING
IPC: G10L19/00
Filed: 2003-10-03
Granted: 2011-03-01
Abstract: Methods and apparatus are provided for communicating an audio stream.  A perceptual mask is estimated for an audio stream, based on the perceptual threshold of the human auditory system. A hidden sub-channel is dynamically allocated substantially below the estimated perceptual mask based on the characteristics of the audio stream, in which additional payload is transmitted.  The additional payload can be related to components of the audio stream that would not otherwise be transmitted in a narrowband signal, or to concurrent services that can be accessed while the audio stream is being transmitted. A  suitable receiver can recover the additional payload, whereas the audio stream will be virtually unaffected from a human auditory standpoint when received by a traditional receiver. A coding scheme is also provided in which a portion of a codec is used to code an upper-band portion of an audio stream, while the narrowband portion is left uncoded.
