This paper presents a novel low air flow rate measuring device. The device was designed to accurately, easily, and in a repeatable way measure the air flow rate through the in-cabin temperature sensor used in automatic climate control systems. The design of the device is briefly discussed and calibration data are presented. Finally, data from some bench-top tests and from in-vehicle measurements are presented.

A Headlight Evaluation Model has been developed which provides a broader and more comprehensive method for characterizing the performance of headlamps than is possible in traditional headlight seeing distance field tests. The Headlamp Evaluation Model accepts as input the candlepower patterns of the headlamp system being evaluated and provides a measure of driver visual performance based on a large number of simulated seeing distance tests and glare discomfort checks on a standardized test route. The output of the Model, termed the Figure of Merit, is the percentage of the distance traveled by the simulated driver on the standardized test route in which the seeing distance to pedestrians and pavement lines, and the discomfort glare levels experienced by opposing drivers, simultaneously meet certain acceptance criteria.
