Programmable Fuel Cell and Grommet Warm-Up Circuitry and Methods for Use in Sobriety Testing Systems

摘要

A subsystem for warming-up a substance sensor within a sobriety testing system includes a memory storing a schedule of times at which tests are expected to be taken by a user. Processing circuitry responsive to the stored schedule activates a heater associated with the substance sensor sufficiently in advance of an upcoming time on the schedule such that the substance sensor is at operating temperature when the corresponding test is requested by at the user.
