This disclosure describes techniques for generating stimulation current pulses that have differing pulse shapes in a medical device. The second transverse seams are positioned such that the outlet parts projecting out from two neighboring tetrahedral shaped pouched are delimited by regions of neighboring transverse sealing seams that are arranged spaced apart from each other and their free ends lie facing each other separated by a common part of the transverse sealing seams. The third fine movement stage measurement system includes an encoder system including a plurality of Y heads and a laser interferometer system including a laser interferometer. Each list partition within the CTA is assigned to one of a plurality of concurrent threads, which executes a prefix sum operation the partition. The receptacle includes a panel and a docking lever pivotally coupled to the panel and movable between a first position wherein docking lever retains the one of a plow bracket and a bracket member so that the receptacle and the one of a plow bracket and a bracket member remain in a mated condition, and a second position. A third-frequency low-impedance circuit may electrically couple the second terminal to the circuit ground.
