A method, a system and a product are disclosed for executing a taskflow in a distributed taskflow architecture and for providing the latter. The cutting element has an elongate tubular body, having a proximal end, a distal end and a cutting tip. The control system may have a control loop controlling the outflow valve motors via open-loop PWM commands and may not have a motor speed feedback in the control loop. The buffer pass and driver transistors are coupled to a sourcedrain path of the cell pass transistor and the buffer pass transistor is coupled between a bitline node and the driver transistor. The shaft is loosely fitted through a hole in the block.
