A first insulating film is formed on a semiconductor substrate. In one embodiment an apparatus can include a plurality of Bipolar Junction Transistors, and a base contact electrically coupled to the side walls of the intrinsic bases of each BJT. The device further includes a stimulation platform, including a sensing circuit connected to the at least one port to sense an intrinsic cardiac signal and a stimulation circuit connected to the at least one port via a stimulation channel to deliver a stimulation signal through the stimulation channel to the electrode. The generally planar surface is at least as wide as the signal trace and is preferably several times wider than the signal trace to provide a short standard with properties uniform over a wide frequency range. Device can include a member whereby it removes the tang portion of a surgical scalpel blade from the holder on the scalpel and places it onto a retention post, where it remains until the blade is safety removed from the handle by a movement of the blade guard. The horizontal arm assembly is configured to prevent reverse pivoting of the seat assembly such that reverse rotation of the golfer’s hips is prevented.
