Abstract: Sensor systems can be used to measure an analyte concentration. Sensor systems can include a base having a distal side configured to face towards a person's skin. An adhesive can couple the base to the skin. A transcutaneous analyte measurement sensor can be coupled to the base and can be located at least partially in the host. A transmitter can be coupled to the base and can transmit analyte measurement data to a remote device.

Abstract: A magnetic recording head motion translation apparatus for use in head/media evaluation systems is disclosed which includes a translator base for holding a magnetic recording head over a media surface, a linear drive unit, and a cam shaped in a pattern that is proportional to the path that the magnetic recording head will follow over the surface of the media. The translator base is equipped with head loading/lifting capabilities and a cam follower bearing, which maintains contact with the cam. The linear drive unit is a stepper motor in combination with a lead screw. Cross-roller bearings are used to connect the linear drive unit to the translator base, thereby providing a stable force in the direction of the Y-axis, while allowing the translator base to move in the direction of the X-axis. The cross-roller bearings are spring loaded in the direction of the cam to force the cam follower bearing to follow the cam's pattern.
