  • Patent number: 8345890
    Abstract: Systems and methods for utilizing inter-microphone level differences to attenuate noise and enhance speech are provided. In exemplary embodiments, energy estimates of acoustic signals received by a primary microphone and a secondary microphone are determined in order to determine an inter-microphone level difference (ILD). This ILD in combination with a noise estimate based only on a primary microphone acoustic signal allow a filter estimate to be derived. In some embodiments, the derived filter estimate may be smoothed. The filter estimate is then applied to the acoustic signal from the primary microphone to generate a speech estimate.

  • Patent number: 8340360
    Abstract: Automatic conflation systems and techniques which provide vector-imagery conflation and map-imagery conflation. Vector-imagery conflation is an efficient approach that exploits knowledge from multiple data sources to identify a set of accurate control points. Vector-imagery conflation provides automatic and accurate alignment of various vector datasets and imagery, and is appropriate for GIS applications, for example, requiring alignment of vector data and imagery over large geographical regions. Map-imagery conflation utilizes common vector datasets as “glue” to automatically integrate street maps with imagery. This approach provides automatic, accurate, and intelligent images that combine the visual appeal and accuracy of imagery with the detailed attribution information often contained in such diverse maps. Both conflation approaches are applicable for GIS applications requiring, for example, alignment of vector data, raster maps, and imagery.

  • Patent number: 8320823
    Abstract: For each audio and data service, a table of contents (TOC) specifies which logical channel may carry data. The TOC may be transmitted over the NRSC-5 transmission system using a pre-defined protocol, which is received and decoded at an NRSC-5 receiver apparatus that extracts the TOC. When a user or an application requests a specific service from the receiver, the receiver logic may examine the TOC and may identify which LC may carry the requested service data. The receiver may only decode the LCs that are needed for the requested service, and may not decode other unneeded LCs thereby conserving power and memory.
