Abstract: A breath alcohol concentration detecting system includes an alcohol detector having a bridge circuit. Before testing a gas sample from a human subject, the system is cycled to provide a reference signal which is stored to indicate the imbalance initially present in the detector bridge circuit. The test is then run to provide an information signal which is compared with the stored reference signal and utilized in the production of an output signal which is some function of the difference between the information signal and the stored reference signal.

Abstract: A magnetic pickup senses rotation of the engine ring gear to provide a frequency-related signal which is translated into a speed-related voltage signal. This voltage signal passes a first speed level w1 at the commencement of a predetermined time period Delta t, established by a multivibrator circuit. At the end of the time period Delta t a second speed level signal w2 is provided. The engine horsepower is then determined by the expression WHERE J represents the motor inertia and k is a constant, to provide a value indicative of the engine acceleration horsepower.

Abstract: A null memory system is provided for gas testing systems of the type that produce a d.c. signal whose maximum amplitude is indicative of the alcohol concentration of a sample in which an initial, just prior to test, output of the gas detector is automatically taken and that d.c. signal stored in a holding amplifier with which the sample''s output is compared, to counter detector drift and to obviate meter nulling.

Abstract: A control system for a breath tester is disclosed. The tester includes a chamber in which a breath sample is stored, a detector unit positioned to test breath therein and means for shielding the detector unit from the chamber while breath is flowing into the chamber and for unshielding the detector unit thereafter to provide a relatively quiescent breath sample to the detector. A purge pump is also provided. The control system includes means for sensing the breath flow into the chamber during the test and for automatically cutting off that flow, timing a period to allow a quiescent state to be reached and only then allowing the detector unit to be unshielded. It also employs the initial offcycling of a thermostatically controlled heater, after the turning-on of the tester, to indicate the approach of operating conditions and includes interlocks to prevent improper operation and to ensure consistent results.

Abstract: A molten metal continuous casting mold level control system is disclosed employing an inductance detector positioned within a water cooled continuous casting mold. The detector is mounted in the jacket of the mold about the generally hollow cylindrical mold core which core includes an electrically conductive form having a billet shaping surface. The output voltage from the detector is bucked against a signal that is related to an input signal, filtered and amplified to derive a signal whose polarity from a reference level and magnitude are proportionate to the direction and magnitude of change in the steel level. This signal is used to control the billet drive to correct changes from the desired level.
