A circuit employing an array of reconfigurable processing elements for wireless baseband processing. A binary image is traversed in windows. The knowledge management system displays via a user interface at least the following information related to at least one incident, the current status of the incident, the recovery guidelines for effecting resolution of the incident, and scoring values associated with the incident. The groove material may have a compressibility that is different from a compressibility of the outer cover layer material. Horizontal control links couple the guide links to a crank system and vertical control links couple the foot support links to the crank system such that rotation of the crank system moves foot receiving areas in a generally elliptical path.
