Abstract: A typical data acquisition system takes periodic samples of a signal, image, or other data, often at the so-called Nyquist/Shannon sampling rate of two times the data bandwidth in order to ensure that no information is lost. In applications involving wideband signals, the Nyquist/Shannon sampling rate is very high, even though the signals may have a simple underlying structure. Recent developments in mathematics and signal processing have uncovered a solution to this Nyquist/Shannon sampling rate bottlenck for signals that are sparse or compressible in some representation. We demonstrate and reduce to practice methods to extract information directly from an analog or digital signal based on altering our notion of sampling to replace uniform time samples with more general linear functionals. One embodiment of our invention is a low-rate analog-to-information converter that can replace the high-rate analog-to-digital converter in certain applications involving wideband signals.

Abstract: The present invention discloses a surgical guide and accompanying depth bur with a method for its use during sinus elevation surgery utilizing the Caldwell-Luc Osteotomy procedure. The surgical guide of the present invention provides accurate transfer of the parameters of the surgical osteotomy to be performed during sinus elevation surgery. It bridges the gap between the precise information obtained from the CT scan and the surgical field on which this surgical plan must be placed. This is accomplished by the use of the surgical guide which is constructed based on the information in the CT scan and the treatment plan prepared utilizing 3-D imaging software.
