Recent Patents in Signal Processing (August 2011) - Compressive Sensing

As readers of this section know, we have changed the format of the "Recent Patents" coverage. Thus far, we had simply listed patents issued in the previous 30 days from various signal processing areas. We think that a much better way to cover recent patents is to highlight an interesting area in contemporary signal processing, and list some interesting patents that have recently been issued in that area. The aim is to draw readers' attention to fertile technical areas as well as the industrial or academic organizations where research in these areas is taking place.

For our August 2011 edition we focus on patents in the area of Compressive Sensing. The selection below includes patents issued in the recent past, and includes inventions on the fundamental sensing apparatus, applications to radar imaging, MR imaging, array signal processing and error control coding. If you have an interesting patent to share when we feature compressive sensing-related patents the next time, or if you are especially interested in a signal processing research field that you would want to be highlighted in this section, please send email to Shantanu Rane (rane AT merl DOT com).
