A system for the intelligent management of knowledge and delivery of content is provided. The apparatus includes at least one suction box positioned downstream of the first dewatering zone. The head has a smooth spherical outer surface that is adapted to engage an acetabular component or native acetabulum. Both are sampled at different times. The conductive resilient component is hidden inside the housing when the sliding component slides into the interior chamber of the housing, and the conductive resilient component is exposed outside the housing to electrically contact the second set of metal contacts when the sliding component slides out of the interior chamber of the housing. The purchase data can be decrypted when fee processing is performed.
