A thin film probe card includes a plate and a plurality of wires on the plate, each of which is electrically connected with at least a thin film probe. A preload is added to a torque command output from each of the velocity control units in the motor control systems for two motors so that torques in mutually opposite directions are generated to suppress backlash between gears. Related methods are also disclosed. The ingestible circuitry finds use in a variety of different applications, including as components of ingestible identifiers, such as may be found in ingestible event markers, e. It is further contemplated that therapeutic strategies that directly target CKS1B or related pathways may represent novel, and more specific means of treating high risk myeloma and may prevent its secondary evolution. The sample is collected in a measuring vessel, in which a piston is guided upwards and downwards in order to press the sample from each direction through a measuring sensor collected at the side of the measuring vessel via communicating tubes connected in an upper and a lower position to the measurement vessel, whereby the sample is stirred totally to eliminate flocculation in the same.
