  • Publication number: 20090276069
    Abstract: A transient echo can be avoided during time stretching of a digital audio signal by detecting a transient in a frame of a digital audio signal, identifying another occurrence of the transient in a subsequent frame of the digital audio signal, rotating the transient occurring in the subsequent frame to align the transient occurring in the subsequent frame with the transient detected in the frame, and aggregating the frame with the subsequent frame. Further, another occurrence of the transient can be identified in another subsequent frame of the digital audio signal and it can be determined that the transient occurring in that subsequent frame cannot be aligned with the transient detected in the frame. The copy of the transient occurring in the another subsequent frame can then be blended across that frame, such as by performing phase accumulation on one or more frequency components.

  • Publication number: 20080222525
    Abstract: Some embodiments of the invention provide a computer system for processing an audio track. This system includes at least on DSP for processing the audio track. It also includes an application for editing the audio track. To process audio data in a first interval of the audio track, the application first asks and obtains from the DSP an impulse response parameter related to the DSP's processing of audio data. From the received impulse response parameter, the application identifies a second audio track interval that is before the first interval. To process audio data in the first interval, the application then directs the DSP to process audio data within the first and second intervals.

  • Publication number: 20070202867
    Abstract: A wireless device incorporates decentralized spectrum management to dynamically control a power level for each channel in a transmission spectrum. The decentralized spectrum management uses a common reference signal received from a TV station to select a channel and coordinate the transmitter power to mitigate interference. The decentralized spectrum management ensures that the propagation loss between the desired and interfering transmitters exceeds a desired power ratio in order to facilitate frequency reuse on a non-interfering basis.

  • Publication number: 20070100456
    Abstract: An intervertebral disc prosthesis comprises a superior endplate, an inferior endplate, and an intermediate core positioned between the endplates. The core comprises a central disc portion and a radial flange. The central disc portion of the core is defined by a superior bearing surface and inferior bearing surface. The radial flange of the core includes a first portion that extends radially outward from the central disc portion of the core. The radial flange also includes a second portion that extends axially from the first portion of the flange. The second portion of the flange extends a substantially greater distance toward the inferior endplate than toward the superior endplate. In one embodiment, the second portion of the flange extends completely to the inferior endplate and engages the inferior endplate when the inferior endplate is in a neutral position relative to the core.

  • Publication number: 20050275240
    Abstract: The present invention is drawn to a cover for an automobile visor. The thin design of the present invention does not add significant bulk to the visor. This feature is welcome, as too much weight or bulk usually will cause the sun visor to sag and eventually work itself loose. The simplicity of the present embodiment is also its greatest feature. It is a low cost yet effective visor cover and protector. The cost and labor to produce such an invention would be very inexpensive and simple. Sun visors are prone to dirt, grease, or grime because drivers are always reaching for them during the drive to either block or unblock the sun. The present invention offers a low-cost and simple way to easily beautify and protect sun visors.
