The lancet device includes a housing and a lancet having a puncturing element. A group of devices may be grouped together to form a domain. An additional embodiment is disclosed which shifts automatically dependent upon the rotational speed of the wheel. The computer system is configured to generate a workpiece model based on the signals produced by the sensor subsystem. Methods for simulating vehicle operation include providing a computer having a pedal activation program, utilizing the pedal activation program to initiate output signals to a pedal sensor output relating to a vehicle condition and transmitting the output signals to an engine control unit to implement a driving profile programmable within the pedal activation program. The thermal conductor 11 is arranged to form no electrically closed loop.
