A method for cooling an imaging device includes providing, by a cold finger, a cold sink to the imaging device and conducting heat from a cold shield, a sensor chip assembly and a leadless chip carrier towards the cold finger through a plurality of parallel paths. The method is implemented by an actuator or sensor, and includes the steps of selecting one of the controllers as the master controller for one or more state variables of an actuator or sensor, detecting a change in the control topology of the cooperative control system, and reselecting a master controller for the one or more state variables responsive to the change in the control topology. The electronic device displays a first menu of the operation panel on the screen. The electrical generator connects to the turbine. The bulk tanks hold the cuttings slurry until it can be discharged via the discharge port to a transport vessel for processing or disposal.
