Abstract: Techniques for data processing and control for a glucose monitoring system are provided, including obtaining a first sensitivity of a glucose sensor; obtaining a second sensitivity of the glucose sensor; comparing a difference between the first sensitivity and the second sensitivity to a predetermined range of values; if the difference is outside the predetermined range of the values, causing a calibration routine for the glucose sensor to be performed; and if the difference is within the predetermined range of values determining a composite sensitivity for a current calibration of the glucose sensor based on the first sensitivity and the second sensitivity and calculating the glucose level based on the current calibration of the glucose sensor.

Abstract: The multipurpose contact lens accessory comprises a casing having a contact end and a viewing end, the viewing end having a lens therein, wherein the contact end engages a contact thereon for viewing and/or insertion of same and the viewing end allows for viewing of the contact engaged to the contact end for determining if any visible defects exist in the contact and/or whether the contact is inside out.

Abstract: An apparatus for converting angular position to a linear voltage. A continuous element dual wiper potentiometer provides triangular waveforms 90.degree. apart to a waveform conversion circuit which generates a linear positive going ramp waveform in response to the angular position of the potentiometer wipers.
