Abstract: A device for infusing liquid into material samples includes a container assembly configured to contain multiple material samples submerged in liquid. The material samples have pores containing air or gas. A pressure source and a vacuum source are both operatively connectable to the container assembly and alternately communicable with the container assembly to force the liquid to at least substantially fill the pores. The samples are thus ready for further processing, testing or use. A method of filling pores in material samples with liquid includes supporting multiple material samples within liquid in an airtight container assembly. The method further includes alternately applying a vacuum source and a pressure source to the container assembly, thereby replacing air with liquid in the pores of the material samples.

Abstract: Ascertaining through integration a bias calibration level for a current control loop of a driver motor of a tape drive. The driver motor includes a current controller having as inputs a demand signal, a bias signal, and a feedback signal. The current controller includes an integrator coupled to the output. The method includes setting the demand signal to a zero current level, setting the bias signal to a level that substantially prevents the integrator from driving itself high, stepping down the bias signal to form a stepped down bias signal, measuring a sense parameter at the output of the current controller, determining whether the sense parameter is high for the stepped down bias signal, and setting the bias calibration level to a level sufficiently above the stepped down bias signal such that the integrator is not driven high when the demand signal is set to the zero current level.
