Implantable, biocompatible scaffolds containing a biocompatible, porous, polymeric matrix, a biocompatible, porous, fibrous mat encapsulated by and disposed within said polymeric matrix, and a plurality of mammalian cells seeded within said tissue scaffold. The jig is made of a fracture resistant material such as aluminium or plastic. Preferably, the viewer may interact in real-time with the enhanced television programming to provide a higher level of engagement and customization potential. The internal components of the controller device include movement detection and measurement circuitry, a self-centering mechanism attached to the fixed central mast, and wires connecting the movement detection and measurement circuitry through the mast to device connection point on the electronic device. An efficiency of heat transfer from selected tissue to be treated to the distal surface of the cryogenic tip is thereby increased. The first and second differential signal pairs are arranged relative to each other in a manner to intentionally reduce or cancel crosstalk introduced by a pinout into at least one of the first differential signal pair and the second differential signal pair.
